Answer:

Genes coding for proteins involved in chiasma formation.

Explanation:

Chiasma is the connecting link between two non sister chromatids from homologous chromosomes. At chiasma chromosomal crossover takes place in which the genetic material is exchanged between the chromatids. During meiosis aneuploidy occurs if chiasma is absent or impaired due to a mutation in genes encoding for proteins involved in chiasma formation.

Aneuploidy is characterised by presence of abnormal number of chromosomes in cells. They can be 45 or 47 in number apart from the usual 46. Due to impaired chiasma, chromosome pair fails to separate and is passed on to the egg or sperm as it is hence there is one gamete with an extra chromosome and one gamete with a less chromosome. Aneuploidy can result in many genetic disorders like three copies of chromosome 21 can result in Down syndrome.

olganol [36]

Answer:

The world climate would drastically change.

Explanation:

  • First off, both poles would have rapid expansion, with the freezing of more water near the poles.
  • Many species of trees and plants would die out in certain areas, since they tend to be in their ideal locations, so the change in climate will make the northern parts of many habitats destroyed.
  • Deserts would expand and the average temperature would rise.
  • Also, many animals would also die out, because of the change in their environments.
  • Conifers would shift southward, causing many forests / parts of forests to turn into wastelands, causing the earth's oxygen production to decrease.

Explain how the data supports your hypothesis.
Viktor [21]

Answer: It is verified by testing it. If the data supports the hypothesis, then we consider the hypothesis to be verified and true. If however, the data does not support the hypothesis or refutes it, then the hypothesis is in trouble, and we have to come up with a different hypothesis to explain the observations.

The answer would be: Increased intracranial pressure caused by blood pooling in the head
A tumour will also apply pressure to the surrounding when growing. <span>It can also obstruct the nearby blood vessels, cause the blood or cerebral fluid to be trapped. The trapped fluid will increase the intra cranial pressure because the skull is a closed space organ. </span>

Does mitosis or meiosis occur more frequently in your body? Explain your answer
vodomira [7]

Answer:

Mitosis

Explanation:

Meiosis is the splitting of sex cells which happens during reproduction. Mitosis is the splitting of body cells in order to make more body cells. Mitosis is how your body grows, therefore it occurs more frequently because the body is not constantly reproducing.
