Answer:
Gravitational time dilation occurs because objects with a lot of mass create a strong gravitational field. The gravitational field is really a curving of space and time. The stronger the gravity, the more spacetime curves, and the slower time itself proceeds.
Answer:
A
Explanation:
I know this because I just took the test and got it right.
Answer:
The correct option is d. In C3 plants the conservation of water promotes photorespiration.
Explanation:
Photorespiration is a metabolic pathway that leads to the loss of half the carbon fixed by photosynthesis, it occurs when the rubisco enzyme (which is responsible for carrying out the carbon fixation) of the Calvin cycle acts on oxygen instead of dioxide carbon. Photorespiration occurs in C3 plants, (considered C3, by the three carbon compound) when the CO2 concentration is reduced. The first step of the Calvin cycle is the fixation of carbon dioxide by rubisco, but at low concentrations of CO2, oxygen begins to be set in place. In conditions of moderate temperatures when C3 plants have enough water, the carbon dioxide supply is abundant and photorespiration is not a problem.
Based on the genotype of AB blood, the a and b genes are codominant.
Since both A and B antigens are equally prevalent on red blood cells, the A and B genes are related in a codominant manner.
<h3>What is gene?</h3>
- A gene is a fundamental building block of heredity and a DNA sequence of nucleotides that codes for the production of a gene product, either RNA or protein.
- DNA is initially transcribed into RNA during gene expression.
- The RNA may execute a specific function directly or may serve as an intermediary template for a protein.
<h3>What is codominance?</h3>
- In terms of genetics, codominance is a sort of inheritance in which two distinct expressions (alleles) of the same gene result in distinct features in a person.
- Animals that exhibit codominance include roan cattle and speckled chickens, which have alleles that express both red and white hair as well as both black and white feathers.
- Plants also exhibit codominance.
