Answer: A
Explanation:
Reproductive cells are haploid, meaning that there's only one copy of each chromosome. Somatic cells are diploid so there's 2 copies of each chromosomes.
if n = 18, then 2n = 36 so A is the answer
Endocrine system is involved in this
The correct answer is D. to a mitochondrion.
<span>Cellular respiration is a four-stage process where a glucose molecule is gradually broken down into CO2 and H2O and some ATP is produced. The steps are:</span>
<span>1: Glycolysis- It occurs in the cytosol, glucose is Broken down into two molecules of pyruvate, ATP is made, and NAD+ is converted to NADH.</span>
2. Transition Reaction-Pyruvate is shuttled into the mitochondria and converted to Acetyl CoA for further break down pyruvate oxidation).
<span>3. The Krebs Cycle, or Citric Acid Cycle- Occurs at the mitochondrial matrix. The acetyl CoA goes through a cycle of reactions and as a result, ATP, <span><span>NADH and FADH2 </span>are produced, CO2 is released.</span></span>
<span>4.The Electron Transport Chain-Occursin the inner membrane of mitochondria, The NADH and <span>FADH2<span> which are made in other steps deposit their electrons in the electron transport chain, (becoming NAD and FAD). As electrons move down the chain, energy is released and used to pump H+ out of the matrix, forming a gradient for further ATP production (oxidative phosphorilation). </span></span></span>
Answer:
The best answer to the question: Which process is the best interpretation of this scenario, would be: C) Microevolution.
Explanation:
Microevolution is defined as the changes in allele expression and frequency within a specific population and which take place within a relatively short period of time regarding evolution. There are different reasons why microevolution might take place, instead of genetic evolution at a much larger scale, and throughout a much larger period of time, which would be typical of macroevolution. These reasons are: mutations, natural and artificial selection, gene flow and genetic drift. In the case of the bird found in Galapagos by Peter and B. Rosemary Grant in 2002, the differences in the finches arose due to natural selection when confronted with a change in their climatic conditions, and therefore, the availability of food. These changes in the environment drove the birds with larger beaks to be first privileged in food acquisition and also in reproduction, making their genetic make-up more prevalent, while those with smaller beaks, due to shortage of food availability, became incapable of passing on their genes to future generations. Natural selection played its role and one set of genes expressed themselves more frequently due to the circumstances and the reproductive process. But when things changed, the situation reversed. This is all characteristic, given the small changes and the reversion, of microevolution, or evolution at a small scale.
