During meiosis but not during mitosis, which of the following is true? __.
A haploid gametes are produced that are identical in their allelic composition
B the cytoplasm divides
C chromosomes line up in the center of the cell during metaphase
D genetic variation among the daughter cells is increased
E two identical daughter cells are produced
Answer:
D. genetic variation among the daughter cells is increased
Explanation:
Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. Meiosis occurs in germ cells, as a result; genetic variation among the daughter cells is increased. These cells (germ cells) are our sex cells – sperm in males, eggs in females.
In meiosis, the haploid gametes that are produced are not identical in their allelic composition.
In prophase 1, the chromosome pair up.
During metaphase, The chromosome pairs line up next to each other along the center (equator) of the cell.
Answer:
Two example of ecosystem with high species is Tropical Rainforest Ecosystems and River and Stream Ecosystems. Both has large number of different species and large number of individuals of different species. I hope the answer helps. Thank you for posting your question here.
Explanation:
All the branches of science that deal with the scientific study of living organism are called life sciences. e.g; botany,zoology,anatomy,biochemistry,embryology etc..
1 - A ground level plant develops curling tendrils that wrap around other objects so it can "climb".
This is a species changing over time as it was originally a ground level plant but began to climb higher.
2 - Over many generations.
This is because diversity takes time and has to be integrated through generations; for instance, marriage. In a family, it becomes more diverse after the next generation as each generation is likely to marry someone of another ethnicity and allow the family tree to become more diverse.
3 - Mutate or Survive
It depends on what it means by mutate - develop a mutation to make it adaptable? If that's the case, then mutations within the DNA would be a result of adaptation and increase survival. Otherwise, survive is the obvious answer as adaption allows for species to move around and live longer.
Hope this helps!
In this question in which is the major source then of free oxygen in the earth's Proterozoic atmosphere is being produce by the evaporation of the ocean water. Hope this answer would be of big help to this assignment then.
