Answer:
up-regulation
Explanation:
Upregulation is where a increases the quantity of a cellular component like protein or RNA in response to an external stimulus.By controlling the number of its receptors, cells may increase and decrease their cell sensitivity.... Hormones can also trigger cells to control themselves by upregulation.( Estrogen is the primary sex hormone for females).
Answer: option B) Sympatric speciation is best described as a random event that disrupts the allele frequencies in a population
Explanation:
Sympatric speciation is an event/situation whereby organisms of the same species:
- live in the same territory or nearby territories ( i.e do not live in geographical isolation)
- DO NOT interbreed, but select a sexual mate from a much diverse territory to yield new species or offsprings.
This sexual selection then results in generations of offsprings that are genetically different from the rest of the same species due to uneven gene flow or disruption of alleles among the population of same species.
Thus, only option B is true.
Answer:
biosphere is the answer bro
Answer:
Sequence C
The answer is letter A. In most organisms cellular respiration usually involves oxygen to produce the most energy. Except in the process of fermentation, where the cells are deprived with oxygen causing it to form bacteria and other forms of organisms within the fermented sample.
