You have spent time working with a population of beetles. Sexually mature males range in size from 2-6 cm in length. You realize
babymother [125]

Answer:

Option B, No

Explanation:

Complete question is as follows -

You have spent time working with a population of beetles. Sexually mature males range in size from 2-6 cm in length. You realize that the females only mate with males that measure less than 3 cm long. If you measured allele frequencies at a single gene (locus) that contributes to overall length, would you expect this population to be in H-W equilibrium from one generation to the next?

Select one:

a. Yes

b. No

Solution -

No, because Hardy Weinberg’s equilibrium theory is not applicable in practical scenario as it assumes that H-W equilibrium persists from one generation to the other only when these is no disturbing factor . These disturbing factors include – natural selection, non-random mating, genetic drift, gene flow and mutations. Since this theory works only in an idealized state where no such disturbances occur, it is very difficult to say that the beetle population can remain in H-W equilibrium. Also the females in the beetle population are selecting the males for mating thereby exhibiting sexual selection. Hence, H-W equilibrium will not be applicable.

Hence, option B

The oldest fossil identifie so far , the stromatolites , represent which type of cell ?
telo118 [61]

Answer:

The correct answer will be option-B

Explanation:

Stromatolites are the sedimentary deposited mounds made of layers of phototrophic microbes which were usually present in the primordial times. The stromatolites are one of the oldest fossils is known today which were formed in the shallow water.

They are composed of the phototrophic bacteria or cyanobacteria which survived and still survive by using the carbon dioxide and sunlight to make food material.

Since the bacteria are the prokaryotic organism therefore, the Option-B is the correct answer.

grigory [225]

Answer:

Charles Darwin

Explanation:

Natural selection, most famously proposed by Charles Darwin, states that when presented with an environmental challenge, some individuals in a species will develop adaptations to face these challenges. Successful individuals will be more likely to mate and their offspring will inherit these adaptive traits, and will continue to pass for generations.

In this sense, plants face the challenge of the cold. Those that adapt to the cold will survive and reproduce, those that can't adapt to the cold will die. Eventually, only plants that can tolerate the cold will survive.

What are two ways in which photosynthesis is important ?
pantera1 [17]
Photosynthesis is a very important thing in nature that affects everyone. It is important because it provides oxygen which is something we must have to be able to survive. Another reason it is important is because photosynthesis is the ultimate source of energy for all the food that humans require and all is the source of energy for some of the supplies we use in life.
