The remains of fossils give scientists clues as to what the world may have been like a long tome ago. If fish fossils are found on the side of a mountain, there may have been a lake there. If a skeleton is found, they can decide what creature it was.
Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP.
<h3>What is respiration?</h3>
Respiration is the process in which cells use oxygen to break down sugar in order to obtain energy. Glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation are the stages of cellular respiration.
So we can conclude that Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP.

Answer:
D. a red allele present on at least one of two homologous chromosomes;
D. unplanned ecosystem interactions
Explanation:
A dominant allele or trait would always mask the expression of a recessive trait when both are present in a pair. The only way a recessive trait can express itself is when it is in a homozygous state. Since red color is dominant over white color in the beetle species, the genotype of any red color species would have a red alelle present on at least one of two homologous chromosomes. For example, if red allele is represented by R and white allele is r, the genotype of a red nettle species would be RR or Rr.
In the second question concerning the most reason for concern that some scientists recommends caution be taken regarding genetically modified plants is that in the process of introducing new genes into a population, unforseen and unplanned disruption of the ecosystem may occur as a result of interaction with the ecosystem that these process and it's product may present.
The correct answer is sympathetic.
Along with the enteric and the parasympathetic nervous systems, it completes the autonomic nervous system of humans. This part of the brain is responsible for 'fight or flight' situations, meaning that if a stressor influences us, the sympathetic nervous system will decide what our course of action is going to be.
