Answer 2
Answer:

Answer:

It reduces the percentage of recombinants.

Explanation:

The independent assortment of genes gives rise to new gene combination and recombinants. Linkage refers to the tendency of two genes present in the vicinity on the same chromosome to get transmitted together.  

Since the linked genes are inherited together, they do not exhibit independent assortment. Due to the absence of independent assortment in linked genes, more of parental types and lesser recombinants are formed.

Orange roughy fish are a fourth-level consumer. We may see fifth- or sixth-level consumers, but not as many as at lower levels on a trophic pyramid. Why are the upper levels of a tropic pyramid limited?

Answers

As energy is lost through the energy pyramid, where it is the primary producers at the base, the upper levels of a tropic pyramid are limited as there is less to consume from as you go down the pyramid.

Answer:

An ecological pyramid is a graphical representation of the distribution of the biomass to different organisms in successive trophic levels. The energy is being lost by 10% in every higher trophic level, when one organism is consumed by another organism in a food chain. Therefore, the number of trophic levels in a pyramid will be limited.  

Which of the following factors does not favor a change in gene frequency and, therefore, evolution?(A) large populations
(B) mutations
(C) emigration
(D) genetic drift
(E) all of the above
Can anyone explain this one?

Answers

Genetic drift does not favour a change as it is all about the variation of genes within a SMALL population; smaller population = smaller variation of genes

All the rest do favour a change in gene frequency

Animals contribute to soil formation through decomposition of organic material. Please select the best answer from the choices provided T F

Answers

Animals contribute to soil formation through decomposition of organic material. This statement is TRUE.

How does animals contribute to soil formation?

  • Organic matter aids in decreasing compaction and surface crusting, enhances water infiltration into the soil, and acts as a reservoir for nutrients and water in the soil.
  • Numerous techniques exist through which animals contribute significantly to the creation of soil.
  • The decomposition of dead animals is one of them, and it provides the soil with organic material.
  • Additionally, animals are able to improve the organic matter in the soil and fertilize it through the excretion of their excrement as well as the saliva of some species of animals, such as the goat, which is beneficial to the soil and plants.

#SPJ2

The correct answer is - True.

The animals are contributing a lot to the formation of soil, and they do this in multiple ways. One of those ways is the decomposition of the dead animals, which gives the soil a nice organic material. Also, the animals manage to increase the organic material in the soil and fertilize it through their feces, as well as through their saliva that can be very useful for the soil and the plants from some types of animals, like the goat.
