During the industrial revolution in England, a population of light-colored moths population fell while a population of dark-colo

red moths population rose. Both types of moths were usually found on the trunks of trees in cities.
Apparently, birds were eating the light-colored moths at a faster rate than they could reproduce. But they were leaving many of the dark-colored moths alone. What is the BEST explanation for this data?




a

The trees had become coated with soot and the dark moths were better camouflaged.

b

Dark-colored moths flew faster than light-colored moths.

c

The birds' vision had become impaired.

d

The white moths had become tastier.

Answer:

A

Explanation:

The darker moths would be harder for the bird to see due to the amount of soot on the trees. The darker moth population would thrive and continue to grow, while the lighter colored moth population would decrease.

Need help with this evolution chart some I've filled in yet I'm not sure if they are correct.Plz help anybody
Svetllana [295]

Answer:

This is correct. The remaining portion:

Sympatric species that form interrelationships undergo coevolution.

Allopatric species in different environments can undergo convergent evolution.

Allopatric species in small populations and under intense environmental conditions can undergo genetic drift.

Explanation:

On the basis of geographical distance, speciation is of two major types:

  1. Sympatric
  2. Allopatric

Sympatric Speciation:

Sympatric speciation is the formation of new species with no gergraphical separation from the ancestor. The new and parent species both exist in the same environment but do not interbreed due to mechanisms of reproductive isolation. These involves both prezygotic and post zygotic barriers to reproduction such as timing of mating, sensitivity to pheromones, choice of mating sites or infertility and mismatched gametes. Species formed through sympatric speciation can form interrelationships and undergo coevolution i.e. the evolution of ones species is dependent on the other.  

Allopatric Speciation:

It involves the geographical separation of the parent and new species. These species could be geographically separated by a river, mountain range or land mass.

Although, allopatric species evolve independently, they may develop similar characteristics that serve different functions. Allopatric species in radically different environments undergo convergent evolution i.e. species evolve similar characteristics without any ancestral homology.

Allopatric species that reside in small populations and are under harsh environmental pressures undergo a rapid genetic revolution i.e. genetic drift. This includes the Founder's and bottleneck effect that involve the continuation of a species from very few individuals after a drastic, sudden environmental change.

Why is the shape of a protein one of its most critical characteristics?
ValentinkaMS [17]

Protein becomes denatured and cease to perform the work if structural changes occur because protein is highly specific in its function. It is stated that the function of the protein is determined by its structure. The proteins are the product of the continuous process of replication, transcription, translation and post-translational modifications. The information stored in it highly specific.

Protein binds with other molecules and perform various physiological functions as it has specific complementary attachment sites, the alteration in the structure would not let it bind to the target and hence desired result will not come out.

Two friends are arguing about the structure of the universe. Caleb says that the universe is made of many galaxies that are made
Fittoniya [83]

Answer:

C. Caleb is incorrect when he says that some galaxies are made of stars and some are made of planets, and Maria is incorrect when she says that galaxies are made up of universes.

Explanation:

Caleb is incorrect because galaxies contain both millions of stars and planets, not one or the other. Maria is incorrect because universes are made up of many galaxies, which are smaller bodies.
