How would genetic variation be affected if, during meiosis I, maternal chromosomes always lined up together on one side of the metaphase plate and paternal chromosomes always lined up on the other side (ignoring the effects of crossing over)

The chromosomes are pulled away from one another from the metaphase plate. Subsequently, all the chromosomes to 1 side are pulled one way, and all the chromosomes on the opposite side are pulled the other way. In the long run, every haploid cell would possibly contain either just maternal or fatherly chromosomes if traverse didn't happen.

The gametes contain either paternal or maternal chromosomes only.

Explanation:

Meiosis is a cell division process that occurs when a four daughter cell arises from a single cell that divides twice.

During meiosis, the identical sister chromosomes chromatids are held together by the chaismata. As the process progresses the chromosomes are separated from the identical pairs by microtubules, each moving away on its own.

These separated chromosomes contain haploid nuclei, each nucleus contains either the paternal chromosomes or the maternal chromosomes.

the element that provides strength to the exoskeletons of clams and oysters is phosphorus.

this is so because calcium carbonate is the main component in the shells. calcium carbonate is strengthened by phosphorus.

explanation:

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
