Answer   Migration, in turn, covers both immigration and emigration. Another key difference is, immigration is permanent while migration doesn’t have to be. People who travel and stay in a country for a few months — for instance, because of a seasonal job they have — are also called migrants.

How could fish-eating birds land on rocky islands be important in the formation of a new community of living things?
maks197457 [2]

Answer:

they would provide nutrients for new living things to feed on.

Explanation:

Fish eating birds would need important in the formation of a new community of living things because as they feed on these fishes on the rocks, they would also be eliminating wastes. The wastes that are being eliminated would serve as a source of nutrient on the Island. With time there would be enough nutrients for plants to tart growing

Write a paragraph explaining how genetic variation, reproductive strategies and environmental pressures have impacted the surviv
Andreas93 [3]

Answer: Genetics and Pressures

Explanation:

For natural selection to occur, a population must have a wide variety of individuals with different traits. For example, natural selection would not influence fish body color if all individuals in a population were exactly the same color. Variation of scale color can help a fish species have a higher chance of survival by confusing predators as to what species they are.

Reproductive strategies represent a set of behavioral, morphological, and physiological adaptations that facilitate access to potential mates, improve the chances of mating and fertilization, and enhance infant survival. Male peacocks have bright, big tail feathers, for example, to attract females. If an organism has a high appeal, this will make them more likely to be able to meet and continue the survival of the species.

Environmental pressures, such as plant death, could influence the survival of herbivorous organisms. Say a small land creature consisted off grass, and an epidemic killed all the grass in their region. They would either die off, or they would evolve to find different types of food. The former could reduce population, while the latter could increase it.

"In genetic modifications, DNA inserted can come from _____ ." any organism containing the DNA of interest only the same plasmid
liq [111]

Answer:

<h2> any organism containing the DNA of interest</h2>

Explanation:

  • Such type of process in which the modification of the genes of the organisms takes place is known as genetic modification and also called genetic manipulation or genetic engineering.
  • In such type of the process, the branch of biological science that is known as biotechnology is used.
  • In this mechanism, genes of interest are separated from the certain organism and then this gene of interest is inserted into the host organism and such type of DNA that is formed after the addition of foreign genes or DNA is called recombinant DNA.
  • Such type of DNA is used in the production of genetically modified organisms and some other fields for the benefit of human beings.
