Answer:
Natural selection by directional selection, was the driving force of evolution at work. The purple flowers parents were able to withstand the selective pressure and therefore emerged from completions with other flowers from previous generation, thus their dominance follow directional selection. This was the trait inherited by their offspring, the dominant purple
The gene pool of purple flower will be large; because of dominance in expression with each successive generation in both homozygote and heterozygote state, and therefore higher frequency of expression compared to the white flowers.
The frequency of allele depends on the rate expression of the allele in the population. Thus, the dominant purple flowers have high frequency of expression compared to the recessive white flowers which can only express itself in homozygote recessive state
Answer:
Carbohydrates, proteins, and fats are all supplementallly neccesary energy reserves in the human body. Another shared characteristic they have is they are all macromolecules.
Explanation:
Answer: Energy at this point is stored as NADH
Explanation: Glycolysis is a catabolic reaction that is made of many steps that breaks down food to give off energy in a form of ATP. Pyruvate the product of glycolysis, is converted to Acetyl-coA using enzyme pryruvate dehydrogenase. During this process between krebs cycle and oxidative phosphorylation NAD takens electron (reduction) and turns to NADH(oxidation) which travels to the mitochondria, our power house, where its converted to energy using redox reactions. To sum up, energy from glucose molecules are transported and exist in forms of NAD to NADH.
Answer:
The answer to your question is below
Explanation:
Because similar to living things, some rocks are formed and it takes a long period to degrade them. During this period new rocks are born, some of these rocks can react with some compounds of the environment and can form new rocks or can be degraded.
What I try to say is that rock formation takes a lot of time and while some rocks disappear new rocks are created.
