Which of these statements is true about adaptive evolution? The ability to learn plays a key role in the process of adaptive evo
pentagon [3]
<span>The correct answer is "Sudden changes in the somatic cells of organisms play a key role in the process of adaptive evolution". Adaption in evolution is caused by sudden gene mutations that affect an organism's offspring and give it - potentially - a better chance of survival. For example, a giraffe who passed on a mutated gene for a slightly longer neck to its offspring gave its offspring a better chance of reaching untouched food, and thus a survival advantage.</span>

Which two codons in the mRNA represent the amino acid phenylalanine
Trava [24]

Answer:

UUU and UUC

Explanation:

Information that encodes certain functional products called PROTEIN are present in the DNA molecule. However, the information needs to be expressed via the processes of transcription and translation. Transcription is the synthesis of a mRNA using a DNA template.

The mRNA then undergoes translation, where it is read in a group of three nucleotides called CODON. Each CODON specifies a particular amino acid. Due to the degenerate nature of the genetic code, more than one codon can specify one amino acid.

Hence, in the case of phenylalanine amino acid, codons UUU and UUC both specify it. This means that whenever UUU and UUC are read during translation, a phenylalanine is added to the peptide chain.

1: There are four stages of meiosis including prophase, metaphase, anaphase, and telophase. In the prophase phase (first stage) the chromosomes becomes visible as paired chromatids. When this happens the nuclear envelope disappears. During metaphase (second stage) the chromosomes attach to the spindle fibers. Throughout anaphase (third phase) the chromosomes move to opposite sides of the spindle fibers. While in telophase (fourth stage) two nuclei form by chromosomes and chromatids moving to the opposite ends of the cell.

2: The cells that outcome from meiosis are haploid daughter cells.

3: Haploid.

4: The similarities of meiosis and mitosis are that they both outcome with daughter from a parent cell. Differences are that mitosis has one round of genetic separation and cellular division while meiosis has two. In meiosis it creates daughter cells that aren’t identical.

Sexual reproduction combines genetics from two parents while asexual reproduction have offspring exactly the same as the genetics of the parent.

Asexual reproduction has the advantage of quicker reproducing. Sexual reproduction have all different offspring that can adapt to many different environments.

What is the main difference between aerobic respiration and anaerobic respiration?
garri49 [273]
The main difference between aerobic respiration and anaerobic respiration is that aerobic using oxygen in the reaction, while anaerobic does not.

Even though both aerobic and anaerobic respiration releases energy, but their reactants and other products are completely different.
For example in human, in aerobic respiration, oxygen and glucose reacts to give out carbon dioxide and water; while in anaerobic respiration, which usually happens during exercise when oxygen is not enough, the muscle cells uses only glucose to produce energy and lactic acid.

Therefore, the main difference is where aerobic uses oxygen, and anaerobic don’t.
