I think it’s sperm for your question
The answer would be <span>thunderstorms.
From what i can see from that picture it seems to me that it's filled with a lot of dark clouds. Because of that, it can mean that it's going to rain a lot or cause a thunderstorm. The option"</span><span>heavy rain or snow" it's not right because when it snows, there are no dark clouds.</span>
Answer:
E) horizontal gene transfer
Explanation:
Horizontal gene transfer(HGT) is mainly seen in bacteria. Bacteria exchange their genetic material from the horizontal gene transfer method. There are three methods in HGT- conjugation, transduction, and transformation.
In conjugation, the bacteria exchange their plasmid through sex pilus. In transformation, bacteria take up other's genetic material from its environment and in transduction virus-mediated gene transfer occurs.
Therefore in bacteria and nucleus, the genetic material exchange can occur only through HGT.
A conversational plan with two habitat preserves, measuring a total of 20 square kilometers combined will preserve more species because this cause segregation of species based on their adaptability towards a safer and secure environment. For example if a lion and deer try to live in the same conservation area, then it’s obvious that the life of deer is always at risk. But in cases of segregated preserved areas both herbivorous and carnivorous animals can live separately. Also if there is special inclination of one species towards other then also these two species can live separately.
Segregation also enhances the diversity in the sense that it could lead to a new ecosystem with a new ecological balance within it. Conservation biologists focus on these areas as they claim that where the greatest number of unique species can be found and protected with in the large number of reserve areas with the least amount of effort
Answer:
The positive charge of the histone proteins get reduced due to the process of histone acetylation, thus making the wrapping of DNA around the histones less tightened. The loose connected DNA afterward associates with the transcription factors for the articulation of the genes situated in that area.
Generally, when there is no requirement of gene anymore, the acetyl groups from the histones get withdrawn by the activity of histone deacetylase enzyme (HDAC9) that makes the DNA tightly wrapped and inaccessible again. In case, when less expression of histone deacetylase enzyme occurs, the process of deacetylation fails to take place. This indicates that within an immune cell, at the time of infection, the inflammatory gene, which was made available does not get re-wrapped firmly around the histones.
