Answer: D. It yields chromosomes that contain both maternal and paternal DNA.
Explanation:
The recombination or crossing over is a genetic process. It takes place during the Prophase I of meiosis. The homologous pair align and held together by synapsis. This results in the mixture of genes combination formed from both parents that can be represented as a single chromosome.
If the recombination do not occur then each chromosome will be either 100% maternal or paternal. Thus recombination assures the recombinant chromosomes which consists of genetic material from both parents. Thus the genetic diversity of offspring increases.
The main site of red blood cell production is the liver.
I believe the answer to be true
BUT I AM NOT 100% SURE!
Answer:
The crop has good yield because Compost has a good effect on root crops.
Explanation:
Compost has a great effect on the development of root crops such as onion, potato, garlic and ginger etc. Compost provide nutrients to these crops as well as soften the soil due to which they grow rapidly. It also improved ventilation, soil structure and soil texture which is very necessary for the crop. Due to ventilation, oxygen gas is available to the roots which increases growth and yield of these crops. Compost also retain water and nutrients so they are available to the roots. So those plots where compost is applied observed increase in yield as compared to other plots.
