Through dating a sample of that rock, we determined the extrusion to be 250 million years old. An intrusion extends from the bottom layer into the fourth oldest layer. Through dating a sample of that rock, we determined the intrusion to be 100 million years old. The principle of superposition states that the oldest sedimentary rock units are at the bottom, and the youngest are at the top. Based on this, layer C is oldest, followed by B and A. So the full sequence of events is as follows: Layer C formed.

The protein encoded by the mutant allele is shorter than the one encoded by the normal allele, the protein encoded by the mutant allele could be non-functional and the mutant allele could be associated with disease. In addition, DNA and mutation can happen possibly wherever on these molecules at any time. The most severe variations take place in the useful units of DNA is the genes in which the mutated form of a gene is named a mutant allele.

How is instructions for your traits carried on DNA molecule​
Anna007 [38]
DNA carries all of the information for your physical characteristics, which are essentially determined by proteins. So, DNA contains the instructions for making a protein. In DNA, each protein is encoded by a gene (a specific sequence of DNA nucleotides that specify how a single protein is to be made).

1.) Which of the following is an electron carrier used to transfer energy in cellular respiration?
Anestetic [448]

Answer:

1. B. NADH

2. B. hydrolysis of ATP.

3. C. ATP is produced from protein.

4. Option C.

5. Option C. Oxygen

6. Option D. Glucose.

7. Carbondioxide.

8. Metabolism.

9. Electron carriers.

10. Electrons.

Explanation:

Cellular respiration is a series of metabolic processes that break down sugars or food to produce energy. ATP is the cellular energy produced during cellular respiration. Cellular respiration requires oxygen which is also called aerobic respiration. There are stages of cellular respiration and they include; glycolysis, pyruvate oxidation, Krebs cycle or citric acid and oxidative phosphorylation. During cellular respiration, glucose is broken down into carbondioxide and water. Along the way, ATP is produced from the processes that transform glucose.

What happens in the alveoli in the process of gas exchange
Andreas93 [3]
Inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli. This is what happens in the alveoli during gas exchange
