The correct answer is option C
The stage of evolution represented by the middle finger must be imbibed by the letter ‘M’ in its name which depicts the “mutation”. In mutation a new gene is added to produce variation in the frequency. The other fingers depict the following stage of evolution:
a) Pointer finger depict the evolution caused by the movement of an individual or species into or out of the area. This finger represents gene flow.
b) The small finger represents the shrinking of population and thus represents the change in gene flow due to any mishappening or epidemic or calamity. This finger represent the small population
c) The ring finger represents the evolution caused by mating/sexual intercourse. This finger represent non random mating
d) The thumb represents the natural selection through adaption.
Answer:
Capillary Exchange Mechanisms
Diffusion, the most widely-used mechanism, allows the flow of small molecules across capillaries such as glucose and oxygen from the blood into the tissues and carbon dioxide from the tissue into the blood.
Explanation:
Answer:
1. D. Only DNA contains genetic information
2. D. Nitrogen and Phosphorus
Explanation:
1. Lipids are insoluble in water unlike other molecules. It stores energy within the fat tissues and cushion internal organs against trauma.
Carbohydrates are sugar units such as monosaccharides, disaccharides molecules which makes up starch that is fuel to your cells.
DNA is a type of nucleic acid that contains genetic information which influences your personal characteristics.
2. The family Rhopalodiaceae has the ability to perform nitrogen fixation, which allows diatoms to fix atmospheric nitrogen. And phosphorus has been found in some diatom species in the Black sea region which does not affect its reproduction rate and also helps in carbon cycle.
Answer:
We can find carbon in diamond
Normal cells in the body follow an orderly path of growth, division, and death. Programmed cell death is called apoptosis, and when this process breaks down, cancer begins to form.
