Describe THREE examples of the effect of altitude on animals.(life science)
Altitude is an elevation from the sea level. It plays an important role in animals as it affects the respiratory rate, pressure on the cells, and homeostasis.
What is the respiratory rate?Respiratory rate is the breathing that involves the inhalation and exhalation of gases through the respiratory system. The breathing rate is reduced due to decreases in oxygen transport at a higher altitude which causes fatigue.
At higher altitudes, the pressure is more and in turn, affects the cells as the body also maintains an osmotic pressure to balance the fluid and internal organs. As the altitude increases the temperature drops which affects the homeostasis of the body resulting in more use of energy to keep warm.
Therefore, altitude affects respiration, cell pressure, and homeostasis.

Explanation:
How many amino acids could be specified if codons consisted of two nucleotides instead of three? What problem would this present for an organism making proteins using all 20 amino acids? I need help with the last part i dont undertsand
Answer:
This could result in a mutation.
Explanation:
A change in the DNA can affect the work of cells because it can cause a mutation; it can be a good mutation or bad. The three main mutations that occur are Insertion, Deletion and Substitution. Insertion is when DNA base(s) are added in, Deletion is when DNA base(s) are removed. Lastly, Substitution is when DNA base(s) are switched on. All of these mutations can have effects. These effects are Silent effect, Missence, and Nonsense. Silent effect is a mutation that does not change the sequence of amino acids in a protein. Missence is a mutation that causes the sequence of amino acids to change. This can cause incorrect protein folding and protein malfunction. Nonsense is a mutation that causes an early stop codon. This effect leads to a protein that is too small. Also a Frameshift can occur. Framshift is when the reading of a frameshift is moved over by one or more bases such that every subsequent amino acid changes. An example of a frameshift is THE CAT ATE THE RAT. If you insert an A at the Beginning this happens ATH ECA TAT ETH ERA T. IN Conclusion there are two Mutations that also play a role in this Point Mutation and Chromosomal Mutaion. Point Mutation is when a single DNA base is either substituted, inserted or deleted from the sequence. Chromocomal Mutation is when large pieces of a chromosome or an entire chromosome is either substituted, inserted or deleted.
16 amino acids could be specified if codons consisted of two nucleotides instead of three.
What do you mean by Codons?Codons may be defined as an arrangement of three consecutive nucleotides in a DNA or RNA molecule that codes for a specific amino acid.
A mutation may be responsible for such problems that would present for an organism making proteins using all 20 amino acids.
A synonymous mutation means that one base within the codon gets substituted for another. Even though the same amino acid is still produced.
It changes the sequences of nucleotide bases within the codon, but ultimately the coded amino acids remain the same.
Therefore, it is well described above.

Which of the following would likely move through the phospholipids of the
cell membrane most easily? *
CO2
Glucose
K+
Starch
Answer:
CO2
Explanation:
Oxygen and CO2 can move through the cell membrane through simple diffusion because they are small molecules.
It's possible that CO2 travels through the lipid bilayer far more quickly than any other molecule. Therefore, option (A) is correct.
What is the structure of cell membrane ?According to the fluid mosaic model, the plasma membrane is a mosaic of components—primarily, phospholipids, cholesterol, and proteins—that move freely and fluidly in the plane of the membrane.
All cells have a cell membrane, also known as a plasma membrane, which separates the interior of the cell from the external environment. A semipermeable lipid bilayer makes up the cell membrane. The movement of materials into and out of the cell is controlled by the cell membrane.
Therefore, small and simple molecules like water, H2O , CO2 can pass through the cell membrane easily as it is partially permeable.

1. What is a stimulus?
2. Why does the body respond to stimuli?
3. What are some different types of stimuli?
4. What are sensory organs and what type of stimuli do these receptors respond to?
5. What is an explanation of how the information from stimuli is communicated to the brain?
6. What is a description of the two things that can happen when the brain processes the information from stimuli?
Hello, 3Coli Here!
Here are your answers:
1. What is a stimulus?
Stimulus is a natural body reaction caused by changes in the environment around or inside the organism. This is a response from the brain.
2. Why does the body respond to stimuli?
The body responds to stimuli, because it needs to protect itself.
3. What are some different types of stimuli?
The two main types of stimuli are external stimuli and internal stimuli. External stimuli are reactions triggered by changes that occur outside of the body, while internal stimuli are reactions triggered by changes inside of the body.
4. What are sensory organs and what type of stimuli do these receptors respond to?
The most commonly used sensory organs include Eyes, Ears, Tongue, Nose, and Skin. Eyes respond to light and motion, because they are used to see. Ears respond to sound, because they hear. The tongue is used to taste, so it senses flavors. The nose is used to smell, so it responds to scents. Finally, the skin is used to feel, so it responds to whatever it feels.
5. What is an explanation of how the information from stimuli is communicated to the brain?
Neuron receptors convert internal and external environments into electrical signals, and then is sent to the brain through nerves.
6. What is a description of the two things that can happen when the brain processes the information from stimuli?
After the brain receives the signal, it will provide a response. One type of response is that the body will physically react to the change. The second type of response is to avoid the change.
Hopefully, this helps! :D
