Answer:
A chromosome contains hundreds of genes, which are composed of DNA.
Explanation:
A chromosome contains hundreds of genes, which are composed of DNA because chromosomes are structures in the cell that contains long strand of genes and the genes are composed of DNA which are located in the cell nucleus.
The genes on chromosomes are arranged in sequence and these have different location within the cell.

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.

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)

write a constructed response on the immune system
Answer:
An immune response is a reaction which occurs within an organism for the purpose of defending against foreign invaders. The first contact that an organism has with a particular antigen will result in the production of effector T and B cells which are activated cells that defend against the pathogen.

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.

many cellular functions can be compared with functions that occur in organisms. which is not a function that both cell and an organism share. A stores waste material for removal B provides structure and support C learn behaviors that aid in survival D conversion of nutrients into usable energy
Answer:
learn behaviors that aid in survival
Explanation:
learn behaviors that aid in survival is not a function that both a cell and organism share because a cell is a basic unit of life and contains some organelles that perform little functions while an organism comprises of many specialised cells that work to perform similar functions. An organism have central nervous system which comprises of brain and spinal cord. Organisms learn new behavior and acquire cognitive skills through the brain development. The brain and spinal cord receive electrical impulses sent from neurons and interpret it to meaningful information.
Learning behaviors that aid in survival is not a function that both cell and an organism share.
LEVEL OF ORGANIZATION:The cell is the basic and functional unit of living organisms. This means that the cell harbors the functional characteristics of living organism.
However, some functions are performed both at the cellular and organism level. Some of these functions include;
