Answer:
Genetic variability. (Ans B)
Explanation:
Sexual reproduction is defined as the development of the new gamete, and it involves the characters of both parents, and showing the new characters from the fusion of male, and female gametes. Some characteristic of sexual reproduction are:
1) It is biparental in nature.
2) Gametes are always synthesized.
3) Fertilization occurs.
4) Meiosis and mitosis both involves.
5) New gamete genetically different from parents.
6) Multiplication is not so rapid.
Answer:
The organism is a prokaryote from the domain Archaea since it lacks organelles and lives in what can be considered an extreme environment.
Explanation:
The organism is <u>single-celled </u>and<u> lacks a nucleus</u>. Prokaryotic organisms generally lack nuclei and other membrane-bound organelles such as mitochondrion and chloroplast. Hence, both attributes are characteristic of a typical prokaryote although being unicellular is not exclusive only to prokaryotes.
<u>Prokaryotes can be bacteria of Archaea</u>. The organism, in this case, also lives in an area that is humid all year round. Such an area can be considered to be an extreme environment. Living in extreme environments is a characteristic that is peculiar to Archaea only.
Organisms in the Archaea domain are generally prokaryotic, unicellular, and live in extreme habitats such as hydrothermal vents, marshes, hot springs, etc.
Answer:
Accumulation of lactic acid
B- have the potential to differentiate into various specialized cell types.
Answer:
An advantageous allele might be dominant or recessive in population. In case of dominant advantageous allele the dynamics is relatively simple because being dominant the allele is expressed both in homozygous and heterozygous condition. Combined with the advantage of natural selection, its frequency increases rapidly.
However, recessive advantageous allele does not increase rapidly because despite being advantageous it gets masked by the dominant allele. When it is rare, it is present in very less number of recessive homozygotes and in slightly more number as heterozygotes. Over the generations, natural selection selects the recessive allele so the number of heterozygotes start to increase slowly. Recessive homozygotes are still rare because they need both the copies of recessive allele. Eventually recessive homozygotes also start increasing in number which leads to the fixation of recessive allele in the population.
