Answer:
See the complete question and the answer below
Explanation:
<em>Suppose that you and a friend see brightly colored pigeons like these at a nature park. Because pigeons are usually gray and white, you both wonder where these colors came from. Suddenly, your friend says, "I have a theory. These birds must get their colors from eating food that has the same colors."Is your friend's explanation a scientific theory? Give reasons to explain your answer</em>
<em>The answer is </em><em>no</em><em>. My friend's explanation is not a scientific theory.</em>
A scientific theory is a tested and proven phenomenon. In order for a statement to become a theory, it must have been tested through experimentation by several independent researchers and found to be true. A mere statement based on perception with little or no experimental test is just a hypothesis and not a theory.
Instead of my friend to have said, "I have a theory", he should have said, "I have a hypothesis".
<span>The limiting factor that keeps the birds from arriving too early in the taiga is the climate surrounding including the temperature and also the precipitation. The following limiting factors are natural occurrences and may have an effect or impact on their own health and lifestyle.</span>

Answer:
3 (Cells carry out the respiration process)
Explanation:
Cellular respiration is a metabolic (catabolic) process common to all living things as all living things need energy for their life processes.
Respiration is the biochemical process in which the cells of an organism obtain energy by breaking down organic molecules in presence or absence of oxygen (aerobic or anaerobic) resulting in the release of Carbondioxide (CO2), water and Adenosine triphosphate (ATP).
Food molecules (containing stored energy in their chemical bonds) absorbed after digestion are broken down and the energy within their molecules are freed. This freed energy in form of ATP, is used to power the organism's movement and physiological functions.
Note that, ATP is an energy carrying molecule and a usable form of energy by cells. This is so because ATP releases energy quickly. Energy is released from ATP when the end phosphate (Pi) is removed to become ADP (adenosine diphosphate), which is a low energy molecule.
Aerobic cellular respiration consists of Glycolysis, Kreb's cycle and Oxidative phosphorylation. A total of 38 ATP molecules is produced in the cytosol of prokaryotes while a total of 36 ATP molecules is produced in the mitochondria of eukaryotic cells.
