Answer And Explanation:
The advantages of asexual reproduction compared to sexual reproduction include the population being able to increase rapidly when the conditions are in their favour, only one parent is needed, it is more time and energy-efficient due to not needing a mate and it is faster than sexual reproduction.
What Molecules are involved in a Nitrogen Cycle?
Answer:
The nitrogen cycle represents one of the most important nutrient cycles found in terrestrial ecosystems (Figure 9s-1). Nitrogen is used by living organisms to produce a number of complex organic molecules like amino acids , proteins , and nucleic acids .
Explanation:
The molecules which are involved in a Nitrogen Cycle include the following:
Nitrate ions (NO3−)Ammonium ions (NH4+)UreaNitrogen cycle is the biogeochemical cycle which involves the conversion of
nitrogen into various forms. This helps to ensure adequate availability and
distribution of the element in the soil and in the atmosphere.

Which part of a flower becomes a fruit?
A.the anther
B.the ovary
C.the stigma
D.the pistil
Explanation:
Anther is where the pollen is released. It drops off from the flower after fertilization.
The stigma is where the pollen falls onto to move down through the pistil towards the ovary to fertilize the ovules.
Both the stigma and pistil drop off after fertilization. Only the ovary and ovules remain, where the ovary becomes the fruit and the ovules become the seeds. (B)

Explanation:
dev, s blood report suggest that the X components in his blood has significant increase because he is suffering from an infection disease. Identify X.
Answer:
The X components of Dev's blood, which increase significantly with infectious disease, are leukocytes.
Explanation:
Leukocytes, also called white blood cells, are the cellular components of the blood that are responsible for the body's defenses and protection.
When a pathogen —usually a bacterium— enters the body, an infectious disease occurs. In response to an infection, white blood cells increase in number in order to fight the infection.
This is why the X component of Dev's blood, leukocytes, increases significantly when Dev has an infectious disease.

Question. Do you think China's one child policy was justified? What alternatives, if any, do you think would have been preferable? Did the policy reduce the impacts of human activity on the environment and if so how?
Answer:
Based on overpopulation, the one-child policy did reduce the amount of offspring, however, it did not account for the preference of males by Chinese parents. The policy was partially justifiable for overpopulation, as the alternative would be to make having children incredibly expensive, to deter anyone from wanting children. The policy did not show large signs of reduction on the impacts of human activity on the environment, however, it did provide less competition in the job market.
