Question 4....??? What effect can bottleneck events have on population that have nearly become extinct????

Biology

ArbitrLikvidat [17]3 years ago
5 0

The answer is; D

It reduces the diversity of the population because some variations in the population can be completely eliminated by the bottleneck effect. Even if the population recovers in population size, the genetic variation will have reduced as compared to the initial population before the bottleneck. For a mall population, this effect can be grave because the reduced genetic variation may mean that the population may be unable to adapt to new selection pressures hence may go extinct.

GuDViN [60]

Answer:

This question lacks options, options are: A) Heterochromatin and euchromatin

B) Uniform in the genetic information they contain

C) Separated by large sketches of repetitive DNA

D) Each void of typical protein-coding sequences of DNA

E) Void of introns.  

The correct answer is A.

Explanation:

The chromatin or substance that makes up the nuclei of cells and that results from the interaction of DNA with histonic and non-histonic proteins and RNA; it can present different degrees of packing or contraction. When chromosomes are stained with chemicals that bind to DNA, densely stained regions and less densely stained regions appear. Heterochromatin are segments of the chromosome that stain strongly and remain visible, practically, during the entire cell cycle. There are few genes in these regions and therefore low transcriptional activity. They are supercondensed regions. Euchromatin are segments of the chromosome that are not visible during telophase and interphase, only in metaphase. It corresponds to regions that are less compact and in which there is a higher gene density.

Answer:

The plant that should be moved to not become malnourished is the plant 3.

Explanation:

The visible spectrum, or optical spectrum, is the portion of the electromagnetic spectrum whose radiation is composed of photons capable of sensitizing the human eye of a normal person. The corresponding range of visible light radiation is identified.

With that being said, plant 3 is in front of a green stained glass. plants have chlorophyll pigment that reflect back the green light, so the green light is least effective for photosynthesis and for that reason it will die as quickly as if it is kept in dark.
