The right answer is: vitamin C and choline
Choline (vitamin B4) is the precursor on the one hand acetylcholine (important neurotransmitter and neuromodulator) and on the other hand, the cascade initiated by betaine (intermediate in the biological methylation and precursor of membrane lipids). In this, it is considered, by extension, as an integral part of the family of B vitamins,
Vitamin C protects against cellular aging, is essential for the immune defenses and increases the assimilation of iron of plant origin. It also contributes to the formation of collagen. Its deficiency leads to a disease called scurvy (hence the ascorbic acid name of vitamin C).

All organisms in an ecosystem are interrelated by the abiotic and biotic resources they use in the course of their lives:
jonny [76]

<span>a)      </span>The milkweed is the primary producer in the ecosystem. It manufactures food from the abiotic factors in the soil such as nitrates and water and those in the atmosphere such as carbon-dioxide and sunlight. The milk weed is then fed on by the caterpillar and a primary consumer. The caterpillar is then fed on the mocking bird (secondary consumer)

<span>b)      </span>Increased human population growth and their activities have resulted in the emission of carbon dioxide and other greenhouse gases in the atmosphere. This has increased the global temperature. This increase of global temperature increase ocean temperatures causing coral bleaching.

Another example is depletion of water sources by human activities hence causing drought. Drought reduces the amount of vegetation growth due to scarcity of water in the soil (due to lowering of the water table) for plant growth.

Assuming no genetic recombination, how many genetically distinct types of gametes can a single human being make?
Georgia [21]

Answer:

Explanation:

Each chromosome represents a twin.like pairs of socks.

This is an analogous problem: you have 2 pairs of socks, one white, one black. Each of the sock is tailored to a specic foot, right or left. How many different ways can the socks be mixed and matched , one for each foot?

Here are the possibilities : left = black, right = black is one such match. Left = white, right = black is another.

so also we will have 23 chromosome pairs
