Answer:
Why is vision considered to be a more effective sense in the terrestrial environment than in the aquatic environment?
Mostly its species bias. Our eyes are adapted to be more effective in a terrestrial environment during daylight. But sea creatures have far more impressive eye adaptations to seeing in the water where our eyes are less effective. The most amazing eyes across all species are the eyes of the octopus. In the water eyes don’t need to see color. Wasting valuable space on the retina for color receptors make it hard to see in the low light found in underwater environments. But the octopus’s eyes see color without having any color receptors. They do this by having lenses that act as a prism and separates light into its various colors. The octopus’s brain aligns the image scattered by color by where each color hits the retina. This allows it to see great in low light and also “see” colors. It uses this for camo to change its colors to blend in with its surroundings both to hunt prey and ide from predators. It can change colors instantaneously. The interesting thing about the octopus is it has no central brain. Its entire nervous system can act as individual brains allowing extreme ability to multitask. One of its eight limbs is thinking about what it will do while another is thinking both independently and with communication to the collective nervous system. reaction time of the octopus’s nervous system is unbelievable. We are very slow by comparison probably because a central brain is far less efficient when it comes to processing and reacting to stimuli. Anyway the question is about eyes so I will end my tangent there. The octopus eye system is probably the most advanced eye that exists. They even climb out of the water and demonstrate great visual acuity while out of the water. Our eyes are extremely limited when we are underwater.
The original base sequence of DNA is : CAG TTA CCA. If the amino acid sequence that results from translation of this DNA base sequence is: valine-tyrosine-glycine, what mutation occurred in the DNA? Explain
A. An addition mutation occurred
B. A deletion mutation occurred
C. A substitution mutation occurred
D. A mutation did not occur.
C
I think substitution, because the original translation of the original base sequence is glutamine-leucine-proline. The base sequence for valine-tyrosine-glycine is: GT# TA# GG# . of course the last codon is unclear, but the first two gives us enough to know too much change happened for a simple addition or deletion mutation. The bases were completely switched out, therefore it is a substitution mutation. I attached a codon chart.
Change to ecosystems occurs both slowly and quickly.

SLO-4.2. Within all tissues in the body, there are stores of undifferentiated cells that can become any specialized type of cell in that tissue for the purpose of growth and healing. Today, Regenerative Medicine is trying to employ these cells to replace tissues that have been destroyed by disease and trauma, such as spinal cord injuries. What are these cells
Answer:
These cells are stem cells.
Explanation:
Stem cells have not specialized to be in a specific tissue and have a particular function yet. They are the cells that give all the different cell types that our body has. In other words, they can become any cell type that the body needs. We call them pluripotent cells because they have the potential of becoming any specialized cell.
Scientists use stem cells in tissue or organ regeneration due to the pluripotential that they have.
can you heat alcohol over an open flame. Give reason for your answer

A big, powerful male gorilla is much more likely than a smaller, weaker
gorilla to become the population's silverback, the pack's leader who mates
far more than the other males of the group. The pack leader will, therefore,
father more offspring, who share half of his genes, and are thus likely to also
grow bigger and stronger like their father. Over time, the genes for bigger
size will increase in frequency in the population, and the population will, as a
result, grow larger on average.

why is one mutation not enough to result in cancer
Answer:
A single mutation is unlikely to result in cancer. Cancer is usually caused by a series of mutations that accumulate throughout the course of a person's life. As a result, cancer is more common in older adults. They've seen more chances for mutations to accumulate.

What is the function of glycoproteins?
A) to serve as identification for the cell
B) to allow specific ions or molecules to pass freely
C) to detect bacteria and other foreign bodies outside of the cell
Answer: Cell-cell recognition, cross-linking of cells and proteins give strength and stability to the cell
Helps in intercellular communication
Some hormones are glycoproteins
Blood clotting proteins are glycoprotein in nature like thrombin, prothrombin
Mucin glycoprotein found in mucus
It is important for reproduction, because they help in sperm-egg recognition
Immmune system relies on glycoproteins
If a pet has to survive without your care, how would its diet change? Write your ideas on the lines below. Read about how organisms get food and energy in their environment
Answer:
rather than consuming "pet food" that contains all proper nutrients required your pet would being to scavenge for food wherever they could find it. Survival instincts would kick in and they would eat whatever they could find. Depending on food availability, loss of muscle mass is a possibility.
Explanation:
If my pet is to survive without me, its diet will change. First of all, he will not get food, so how is it possible for a living being to survive without food. It will get skinny and starve to death after a few days.
What is Diet?Diet is defined as the sum of food that is consumed by a person or other organism. The term diet refers to the use of a specific intake of nutrition for health or weight-management reasons. Humans are omnivores so, every culture and every individual has some food preferences or some food taboos.
It is essential for good health and nutrition protects you from many chronic non-communicable diseases like heart disease, diabetes and cancer. Eating a variety of foods and consuming less salt, sugar, and saturated and industrially produced trans-fats are important for a healthy diet.
Thus, if my pet is to survive without me, its diet will change. First of all, he will not get food, so how is it possible for a living being to survive without food. It will get skinny and starve to death after a few days.

In the logistic growth model, as a population approaches the carrying capacity, what happens to its growth rate?
A
becomes exponential
B
doubles
C
increases
D
slows to zero
In the logistic growth model, as a population approaches the carrying capacity, the growth rate of the population will slow down to zero. Thus, the correct option is D.
What is Logistic growth model?The logistic growth model is a parameter which represents the rate at which the population would grow if it were unencumbered by the environmental degradation. A second parameter, that is K, represents the carrying capacity of the system of species which are being studied.
In logistic growth, a population's per capita growth rate gets smaller and smaller as the population size when it approaches a maximum imposed by the limited resources in the environment, known as the carrying capacity (K). Exponential growth model produces a J-shaped curve, while logistic growth produces an S-shaped curve.
Therefore, the correct option is D.
