Answer: a. Genetic recombination (crossing over)
b. Can also be explained in terms of crossing over
c. Non disjunction of homologous chromosomes in meiosis 1
Explanation:
The process that allows for the transfer of both the paternal and maternal materials to is the crossing over process that takes at meiosis 1 changing them to secondary spermatocytes. While they are still primary spermatocytes, they are still diploid cells having both the maternal and paternal chromosomes. But since the spermatozoon is an haploid cell, it is able to retail some of both parents chromosome by the crossing over event which takes place between homologous paternal and maternal chromosomes allowing them to exchange materials. Thus the chromosomal contents of the primary spermatocyte differs from that of the spermatozoon.
C. This can occur as a result of the one of the homologous chromosome pair refusing to separate at meiosis 1 with one gamete containing 4 chromosomes/8 sister chromatids and the second having 2 chromosomes/4 sister chromatids.
Answer:
I did this and i got A. I got it correct so you should too.
Answer:
C) OXIDATION
Explanation:
Oxidation is the reaction of a substance with oxygen. When a rock reacts with oxygen, it forms iron oxide, which weakens the rock.
Answer:
Algae is a primary producer
Explanation:
they use inorganic ions, co2, h2o and solar energy the complex organic molecules are produced. They release oxygen in this process. Algae, cyanobacteria and plants indirectly produce all food and all oxygen for all living organisms on our planet
Answer:
During photosynthesis the tree while convert the energy from sunlight into sugar (glucose). The xylem will transport the water to the leaves. The phloem will transport the glucose. The energy from sunlight will also be used to convert water and carbon dioxide into oxygen and glucose. Hence, the energy stored within the glucose/sugar molecules will be used to help the tree grow.
Explanation:
I wrote it in my own words but it will probably say i took it from go ogle since used similar terms apparently.
hope this helps and is right. p.s i really need brainliest :)
