Answer:

Option 1: XnY

Explanation:

X-linked recessive traits can occur in both males and females. Since its recessive it needs both XnXn in females to show up but for males who are hemizygous (XY) they only need a defective copy of Xn for the disease to show up thus option 1 is correct.

6 reasons why Meiosis and mitosis are different (PLEASE HELP)

Answers

Answer:

Reasons why they're different :

Explanation:

1. Mitosis is reserved for somatic cells while meiosis is reserved for sex cells (gametes).

2. Mitosis results in identical cells , while meiosis results in genetically distinct cells.

3. Mitosis undergoes one round of cell division while meiosis undergoes two rounds of divison.

4. Mitosis results in diploid daughter cells, while meiosis results in haploid daughter cells.

5. Unlike mitosis, meiosis differs in males and females.

6. Mitosis creates a human cell with 46 chromosomes, while meiosis creates a human cell with 23 chromosomes.

Julio is studying the evolutionary history of desert cottontail rabbits, sea otters, and grizzly bears. All three species share some body structures, but all three also have some differences in their body structures. Below is a table that includes some of the body structures Julio is studying. How could Julio explain why all three species share some body structures and have some differences? Why do only grizzly bears and sea otters have canine teeth?

Answers

Answer:

Explanation:

One way that Julio can explain such differences is that their environments are very similar and therefore the traits that were best suited for their survival were passed on from generation to generation. The traits that each species developed differently would have been due to their diet. Each species has a different diet and certain traits allow them to more easily hunt/gather the food that they need to survive. For example, grizzly bears and sea otters both eat fish as their main diet and therefore have both developed canine teeth, while rabbit teeth are different due to them only eating vegetation.

What type of mutation occurs when a nucleotide is added to the DNA?

Answers

Answer:

A frameshift mutation.

Explanation:

A frameshift mutation is when one adds an extra nucleotide to a series of nucleotides. This will mess up the order of the nucleotide, thus when it forms the codons, and eventually, the amino acids; all of the codons are wrong, thus all of the amino acids are wrong.

In this situation, an extra nucleotide is added to a sequence of DNA, this results in all of the other nucleotides getting pushed over by (1). Thus, all of the nucleotides form the wrong codons and the wrong amino acids. Therefore, a frameshift mutation has occured.

Using a specific example, predict and explain how the release of non-native organisms can affect local, national, and even global ecosystems.

Answers

A nonnative species may not have any natural predators when being introduced subsequently it won’t have any competition with the other organisms living in the same ecosystem. This will make the other organisms struggle for food and other resources and could potentially make them go extinct. They can also have drastic effects to the local biodiversity (for the previous reason). Also, due to the competition or newly introduced predator (assuming they’re a predator) the preexisting organisms of the ecosystem may start to relocate and start a new ecosystem or if there are neighbouring towns/cities may have to forage for food there - which would obviously be dangerous for both them and us. Hope these few examples help.

Answers

Answer:

25%

Explanation:

If a parent is heterozygous, it has 2 difterent alleles. Both parents are heterozygous for blood type A, so the genotype is AO. A masks the O because A is dominant over O, so A is the blood type.

Create a punnett square to find possible offspring

AA = Blood type A

AO = Blood type A

OO = Blood type O

There is 1 child out of 4 that have blood type O. So to find the percentage divide 1 and 4 and multiply by 100.

1÷4×100 = 25

Answers

the process that plants go through to capture and use energy from the sun to make food (glucose ) is called Photosynthesis

The process that plants go through to capture and use energy from the sun to make food ( glucose ) is called [tex]\sf\purple{photosynthesis}[/tex].

..................................................More:-

Photosynthesis is a process by which phototrophs convert light energy into chemical energy.

The word “photosynthesis” is derîved from the Greek words "phos" (which means “light”) and "σύνθ-εóîς" (which means “combining together.”) And so it means “combining together with the help of light.”

The process of photosynthesis occurs in green plants (the primary producers in a food chain) and a few other autotrophic organisms such as cyanobacteria, purple bacteria and green sulfur bacteria.

Following is the photosynthesis formula:

︎︎︎ 6 CO2 + 6 H2O —> C6 H12 O6 ([tex]\sf\blue{glucose}[/tex]) + 6 O2 ([tex]\sf\pink{oxygen}[/tex]).

B. Into the cell. They want to move from low to high concentration (UP the concentration gradient).

Answers

Answer:

A. Out of the cell. They want to move from high to low concentration (DOWN the concentration gradient)

Explanation:

Although the cuticle provides important protection from excessive water loss, leaves cannot be impervious because they must also allow carbon dioxide in (to be used in photosynthesis), and oxygen out. These gases move into and out of the leaf through openings on the underside called stomata (Figure 3b).

Answer:

ground penetrating radar

Ground penetrating radar technological tool helps earth scientists gain new knowledge about earth’s subsurface. Thus the correct option is C.

What is Ground penetrating radar?

Ground penetrating radar detects non-metal and metal objects, as well as voids and underground irregularities. It makes possible to measure the depth, dimensions, thickness of targets. It provides data quickly and can cover a large site area.

Ground penetrating radar can go deep up to 100 feet (30 meters) in low conductivity materials such as dry sand or granite. Moist shale, clays, and other high conductivity materials, may attenuate or absorb GPR signals, greatly decreasing the depth of penetration to 3 feet (1 meter) or less.
