Organisms use different types of adaptations to aid in their survival. many different types of animals hibernate throughout the
zalisa [80]

Option (A) Torpor is the correct answer

Organisms that undergo hibernation have the ability to slow down their metabolism so as to lower the core temperature. This process is known as Torpor.

<h3>Why is torpor important for organisms undergoing hibernation?</h3>

Torpor is a state in animals where they lower all their metabolic activities and bodily functions so as to keep the body temperature low.

It is done by the animals to conserve resources in conditions where scarcity of food is there.

Some birds undergo torpor to conserve fat in the body.

Some animals use this technique of torpor to survive competition with other species.

These organisms come back to normal physiology when the conditions become favorable.

The science of describing, naming, and classifying extant and extinct organisms is:__________
Sloan [31]

The answer is Taxonomy.

The science of describing, naming, and classifying extant and extinct organisms is <u>Taxonomy</u>.

What is taxonomy?

All of the world's plants, animals, and microorganisms are included in taxonomy, which is the science of naming, describing, and classifying species. Taxonomists identify, describe, and classify species, particularly those that are novel to science, using morphological, behavioral, genetic, and biochemical observations. Taxonomy recognizes and catalogs the elements of biological diversity, offering the fundamental information necessary for the management and application of the Convention on Biological Diversity. Unfortunately, our understanding of taxonomy is far from complete. Taxonomists have identified roughly 1.78 million species of animals, plants, and microorganisms throughout the past 250 years of study, but the true number of species is unknown and likely between 5 and 30 million.

Generally speaking, superficial categorization of living things develop according to necessity. Any crawling object, such as a snake, earthworm, intestinal parasite, or dragon, has been referred to, respectively, by the Anglo-Saxon phrases worm and fish. There are more anatomical distinctions between a shellfish and a starfish than there are between a bony fish and a man, despite the fact that the terms shellfish, crayfish, and starfish all include the term "fish." There are many different types of vernacular names. The English robin (Erithacus rubecula) is not the American robin (Turdus migratorius), for instance, while the mountain ash (Sorbus) only superficially resembles a real ash.

5. DNA replication of the circular chromosome in E. coli begins when a protein called DnaA binds to the replication origin on th
dem82 [27]

Answer:

Adenine; Thymine

Explanation:

  • The origin of replication in E.coli is called the oriC
  • This region is rich in Adenine and Thymine bases because their base stacking interactions are weaker than those of Cytosine and Guanine.
  • Between A and T bases there are only 2 hydrogen bonds (not a very strong interaction so requires less energy to separate) while between C and G bases there are 3 hydrogen bonds (strong interaction thus requires more energy to separate)
  • The oriC is a region which needs to be separated when replication occurs. It is thus a region which requires easy separation with as little energy as possible so that proteins like DnaA can bind.
