The question is incomplete. Th ecomplete question is

A population of birds lives on a small island. Another population of the same species lives on the mainland. The distance between the island and the mainland is too great for birds to fly back and forth. Recently, a series of sandbars and tiny islands have formed between the island and the mainland. what is the most likely effect of this?

A) an increase in mutations in both bird populations

B) an increase in gene flow between the bird populations

C) an increase in genetic drift between the bird populations

D) an increase in mutations in the island population

Answer:

B) an increase in gene flow between the bird populations

Explanation:

same species divided by geographic boundaries are unable to migrate due to distance but if both the species with able to migrate, then there will be increase in gene flow.

Gene flow is defined as transferring of genetic diversity among the population due to introduction of migrants. Migrants allows the chnages in genetic diversity by modifying the allele frequencies among the population.

Formation of sandbars and tiny islands will increase the chances of migration, as now either birds can take hold at tiny islands while moving to mainiland or small islands or both the population can migrate to tiny islands which directly results into increasing gene flow. Gene flow will further increases the diversity among bird populataion.

Hence, the correct answer is B.

Answer: B) an increase in gene flow between the bird populations.

Explanation:

The formation of tiny island will connect the island and the mainland. The distance between the two habitats will reduce due to the tiny island which can also become another habitat for birds. Thus the gene flow will increase between the birds of two different habitats as the population of two habitats can mate and produce progeny.

Leto [7]

Answer:

Behavioural

Explanation:

There are three components of behaviour that makes us act and think in a way that allows us to run our lives the way we feel comfortable and these are

  1. Behavioural
  2. Cognitive and
  3. Affective

In terms of Behavior, this component is the one that drives the way a person will behave towards a certain thing. In this case, an undesired pregnancy. This will be for the benefit of the person in long or short term and will provoke them in a way to take precautionary measures.

I need help with number 28,, anyone wanna answer it for me ?
Amanda [17]

Answer:

Carbohydrates: Carbohydrates are the most abundant organic molecules in nature. stored in the body in the liver and muscles in the form of glycogen.

Proteins and Amino Acids: Proteins are the most abundant organic molecules of the living system. There are twenty amino acids (AA) which have been found to occur in all proteins and for which genetic codon exits.

Lipids are broadly classified (modified from Bloor) into simple, complex, derived and miscellaneous lipids, which are further subdivided. found in cell membranes, cholesterol, blood cells, and in the brain

Dephosphorylation of glycogen synthase: ____________
jenyasd209 [6]

Answer:

b. Increase in activity of glycogen phosphorylase.

Explanation:

Glycogen synthase exists in two forms which is phosphorylated form which is covalent modification of serine residues by ATP and dephosphoryated form which is obtained using phosphatase on phosphorylated form. Glycogen phophorylase catalyzes hydrolysis of glycogen which shortens glycogen molecules.

What type of molecule contains the most energy?
Effectus [21]

Answer:

Lipids

If i were to guess, without any answer choices, I would say that we get out energy from carbohydrates, and we store energy in lipids, so Lipids (being long chains) might have the most energy.

Explanation:

Please tell me if this is wrong, I did not have much to work with without any answer choices, and this was very broad. :)
