All of the following adaptations allow for reproduction on land except
external fertilization.
eggs with sufficient food supply.
desiccation-resistant eggs.
amniotic eggs.

Answers

Answer 1

External fertilization (a) is the adaptation that does not allow for reproduction on land, while the other adaptations listed (b, c, d) enable successful reproduction in terrestrial environments.

The adaptation that does not allow for reproduction on land is a. external fertilization. External fertilization refers to the process of fertilization that occurs outside the body, typically in aquatic environments. This method is commonly observed in many aquatic organisms, where eggs and sperm are released into the water, and fertilization takes place externally.

On the other hand, the remaining adaptations listed (b. eggs with sufficient food supply, c. desiccation-resistant eggs, and d. amniotic eggs) are all adaptations that enable reproduction on land.

b. Eggs with sufficient food supply: Land-dwelling organisms, such as reptiles and birds, produce eggs with a sufficient food supply to support the developing embryo. These eggs contain nutrients and protective structures that allow for successful development outside of water.

c. Desiccation-resistant eggs: Many terrestrial organisms, including insects and amphibians, have evolved desiccation-resistant eggs. These eggs have specialized membranes and structures that prevent them from drying out in dry environments, enabling them to survive and develop on land.

d. Amniotic eggs: Amniotic eggs are a defining feature of reptiles, birds, and monotremes. These eggs have a specialized protective membrane called the amnion, which surrounds the developing embryo and provides a stable internal environment. This adaptation allows for the development and hatching of embryos on land.

Overall, external fertilization (a) is the adaptation that does not allow for reproduction on land, while the other adaptations listed (b, c, d) enable successful reproduction in terrestrial environments.

Why are flowers so important to a plant?

Answers

Answer: Flowers help purify water and also helps hold the soil in place and prevent erosion.

CREDIT: fed.us

Answer:

The primary purpose of a flower is reproduction. Since the flowers are the reproductive organs of plant, they mediate the joining of the sperm, contained within pollen, to the ovules — contained in the ovary. Pollination is the movement of pollen from the anthers to the stigma.

chromosome 7 has a gene named foxp2. if this gene were spliced into non-human animals, would they be able to produce speech?

Answers

Chromosome 7 contains the gene FOXP2 which is involved in speech and language development. The FOXP2 gene is important in the development of certain parts of the brain that are necessary for speech and language. However, simply splicing the FOXP2 gene into non-human animals would not be sufficient for them to produce speech.

Speech and language are complex behaviors that involve a variety of factors including brain structure, neural connections, and muscle control. While the Chromosome 7 consisting FOXP2 gene is involved in some aspects of language development, it is not the only gene involved, and it cannot by itself give animals the ability to produce speech. Moreover, the human version of the FOXP2 gene differs from that of other animals in important ways. Mutations in the FOXP2 gene in humans have been associated with language disorders, and studies have shown that the gene plays a role in the development of certain brain regions involved in speech and language. Therefore, while splicing the FOXP2 gene into non-human animals might lead to some changes in brain development, it would not be sufficient to give them the ability to produce speech as seen in humans.

Answers

Answer:

1. an electrical nerve impulse sent by nerve fibers to the central nervous system for interpretation. Action potential.

2. neurons that detect chemicals such as those found in food. Chemoreceptors.

3. type of eyes many arthropods have; eyes that protrude outward and consist of many lenses. Compound eyes.

4. the structure that gives the response to an environmental change. Effector

5. neurons that detect electrical fields. Electroreceptors.

6. secretion of hormones into the blood stream to affect distant processes. Endocrine.

Explanation:  

An action potential is a change in the internal charge of a cell due to depolarization. These changes allow the transmission of a message from any part of the body to the central nervous system. The central nervous system will interpret the message and will give a response.

There are different types of receptors in our bodies. Chemoreceptors are the ones that detect chemicals and produce an action potential or a neurotransmitter. These receptors respond to chemicals. Another type of receptor is the electroreceptors. They detect electrical fields and are only on the skin of aquatic animals.

Compound eyes have a large number of ommatidia. As a result, the anthropods with this type of eyes have a large view angle. In other words, every ommatidium sees an image, and the final product is a combination of all of them.

The effector is the structure that gives an answer once an affector has sent the message to the nervous system that there was a change in the environment.

There are different kinds of secretions, autocrine, paracrine, and endocrine. In the endocrine secretion, the gland secrets hormones into the bloodstream so that they can travel long distances up to their target cell, which is far from the gland.

Select the correct statement about the three-chambered hearts of amphibians and nonbird reptiles. A scheme of blood circulation of reptiles except for birds. The reptiles have a three-chambered heart that consists of two atria and one ventricle with an incomplete septum. There are two circuits: pulmonary and systemic. In the pulmonary circuit, the blood from the right ventricle is pumped in to lung capillaries and returned to the left atria. In the systemic circuit, the blood is pumped from the left ventricle to the systemic capillaries via the left systemic aorta and is then returned to the right atria. There is also one vessel going from the right ventricle to the aorta right before it branches to smaller arteries. This vessel carries mixed blood. All blood on the right side of the circuits is venous and all blood on the left side is arterial. Select the correct statement about the three-chambered hearts of amphibians and nonbird reptiles. The three-chambered hearts of amphibians and nonbird reptiles are facultative, allowing variation in blood flow through the heart. The three-chambered heart is inferior to the four-chambered hearts of birds and mammals, limiting the evolutionary success of amphibians and nonbird reptiles. Pulmonary and systemic blood fully mixes in the ventricle of a three-chambered heart.

Answers

Answer:

The three-chambered hearts of amphibians and nonbird reptiles are facultative, allowing variation in blood flow through the heart.

Explanation:

In Anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.

Generally, the cardiac cycle occurs in two (2) stages;

I. Diastole : in this stage, the ventricles is relaxed and would be filled with blood.

II. Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.

All amphibians and reptiles except for crocodiles (having four-chambered heart) have three-chambered hearts, which typically comprises of a partially divided ventricle and two atria.

Hence, the correct statement about the three-chambered hearts of amphibians and nonbird reptiles is that, the three-chambered hearts of amphibians and nonbird reptiles are facultative, allowing variation in blood flow through the heart due to the partially divided ventricle.

which group of genes in drosophila embryos must be mutated if the result is elimination of a significantly sized, contiguous region of segmentation?

Answers

The group of genes in Drosophila embryos must be mutated if the result is the elimination of a significantly sized, contiguous region of segmentation is gap genes.

What are gap genes?

Gap genes are a group of genes that are expressed throughout the central region of the Drosophila embryo. Gap genes, along with other segmentation genes, are responsible for establishing the boundaries between segments in the developing Drosophila embryo. Gap genes are classified into three broad categories: anterior, middle, and posterior, based on their expression patterns.

Gap genes in Drosophila are required for correct patterning of the anterior-posterior axis of the embryo. Gap genes are necessary for defining the broad regions of segmentation, which are then subdivided into smaller regions by pair-rule genes. The proper patterning of the Drosophila embryo requires the activity of gap genes.

In contrast to maternal genes, which establish the anterior-posterior axis of the embryo, gap genes define large, contiguous regions of the developing embryo and are necessary for setting up the basic body plan.

.how does contraction of a single muscle cell, which would cause tension on the surrounding endomysium, ultimately cause tension on the tendon of the muscle?

Answers

When a single muscle cell contracts, the causes tension on the surrounding endomysium, ultimately causing tension on the tendon of the muscle to be transferred to the surrounding endomysium.

What is a contraction?

Contraction is the act of pulling or tightening a muscle through the movement of the muscle fibres. This movement generates tension, which is transmitted through the endomysium to the tendon of the muscle.

A single muscle cell is the fundamental unit of muscle contraction. The contraction of these cells results in a number of biochemical and biophysical changes within the cells, culminating in muscle tension. The tension is transferred to the surrounding endomysium, which is a thin layer of connective tissue surrounding each muscle fiber. When tension is applied to the endomysium, it transfers the force to the perimysium, which is a thicker connective tissue layer that surrounds bundles of muscle fibers.

Finally, the tension reaches the epimysium, which is a dense layer of connective tissue that surrounds the entire muscle. The epimysium is continuous with the tendon, which is a tough band of connective tissue that connects the muscle to the bone. Therefore, the contraction of a single muscle cell causes tension in the tendon of the muscle.

If a mutation has no effect on fitness, it may stay in the gene pool indefinitely.
TRUE/FALSE

Answers

The given statement "If a mutation has no effect on fitness, it may stay in the gene pool indefinitely" is true because If a mutation has no effect on fitness, meaning it neither enhances nor reduces an organism's ability to survive and reproduce.

It is considered neutral in terms of natural selection. In this case, the mutation can persist in the gene pool indefinitely. Since natural selection acts on traits that affect an organism's fitness, mutations that have no impact on fitness are not subject to selective pressures. As a result, these neutral mutations can accumulate and persist in a population without being eliminated by natural selection.

Over time, the frequency of these neutral mutations may fluctuate due to genetic drift, migration, or other factors, but they can remain in the gene pool over generations. It's important to note that even though a neutral mutation may persist, it may still be lost or go to fixation in a population due to random chance or other evolutionary forces.

A 15.0 kg block is attached to a very light horizontal spring of force constant 475 N/m and is resting on a smooth horizontal table. (See the figure below (Figure 1) .) Suddenly it is struck by a 3.00 kg stone traveling horizontally at 8.00 m/s to the right, whereupon the stone rebounds at 2.00 m/s horizontally to the left.A. Find the maximum distance that the block will compress the spring after the collision.(Hint: Break this problem into two parts - the collision and the behavior after the collision - and apply the appropriate conservation law to each part.) Metal Pad Manufacturer: MetalCo Pile driving machines like the one pictured below use a powerful hammer to drive metal or cement piles into the ground to form the foundations of buildings. Your company, MetalCo, has invented a new product, a curled metal pad that can be used to cushion the shock between pile driving machine hammers and the piles. Cushioning pads keep the shock of the hammer strike from damaging the pile as they are hammered into the ground. Each year about 300 million feet of piles are driven in the US. In the past, the pile driving companies simply used blocks of wood which sometimes caught on fire, so now they mainly use unbranded pads made of pieces of asbestos-like material that they buy from local industrial supply houses for about $3 a piece. These supply houses sell a wide variety of products needed by construction companies. They mark-up their products to sell for 30% over their cost to buy the products. Typically, pile-driving companies rent their equipment and pay their workers an hourly wage. Rental and labor costs geth are about $150 per hour per machine. MetalCo is a small ($20m in sales) but successful firm specializing in a metal wire twisting technology typically used for making various kinds of filters for the automobile industry. Your new product is a completely new application of this technology. It is made from metal wire twisted to form a coil and then wound to form a pad. The pad is expected to transfer the driving energy to the pile much more efficiently and is protected by a patent. Each pad costs $25 to make and will not require any additional investment in plant or equipment. Your company has a policy of marking up its products by 50% over the variable costs of manufacturing. After months of effort, a responsible pile-driving contractor, PileCo, finally agreed to try your new metal pads - no strings attached. The test job was typical and required 15,000 feet of piles to be driven. A job this size would require approximately 100 of the asbestos-like pads and would drive piles at a speed of 100 feet per hour. PileCo appeared to be very excited by the results. So far all you know is that the new pads significantly increased the speed with which piles could be driven and that just 5 pads were needed for the entire job. You are scheduled to meet with PileCo to negotiate selling your metal pads to them directly (i.e. skipping the supply house) for a period of 1 year. How would you price the new metal pads?1. Calculate the price you would be willing to accept for metal pads.2. Consider how you would promote the new pads.
