The molecule shown below is a molecule that is generally termed as the energy currency molecule of the cell, and that is ATP.
The components of it include:
1. Adenine nitrogenous base, the far left
2.Ribose, sugar the same sugar found in RNA molecules, middle.
3. Triphosphate - 3 covalently bound phosphate groups ready to split apart as they don't typically like being bonded in that manner, due to charges on phosphate, being negatively charged.
Maybe D but at the same time it could be A
Answer:
Environmental factors can influence natural selection because they can increase or decrease the amount of genetic variation in a population.
Explanation:
Natural selection is a process that involves the survival of species through changes in the expression of their genes, making possible the process of adaptation to environmental changes. It is one of the explanations for the biological evolution of species.
The second premise, necessary for natural selection to be possible, implies the existence of a variability (genetics) of traits among individuals in a population.
The other premises of natural selection are the faculty of traits to be inheritable and that genetic variability should lead to reproductive success and survival.
- <em>The other options are not related to the process of natural selection, since it is not possible for natural selection to increase or decrease the number of chromosomes, in addition to the fact that genetic variability must be observed in a population, not in a single individual, to be considered natural selection </em>
Answer:
h - height
Explanation:
gravitational potential energy = m * g * h
m stands for mass. Mass doesn't change in physics
g stands for gravitational acceleration. It is a constant.
h stands for height. When the skater moves up and down the track the height from the ground changes. Therefore this variable does change.
The answer to this question would be: on the rough endoplasmic reticulum.
Digestive cell produces many enzymes which were made by protein. Endoplasmic reticulum has a role in protein synthesis. It is important to have many rough endoplasmic reticulum to accommodate the protein synthesis function so that the digestive organ can produce enough enzyme
