In prokaryotes, new mutations accumulate quickly in populations, while in eukaryotes, new mutations accumulate much more slowly.
musickatia [10]

In prokaryotes, new mutations accumulate quickly in populations, while in eukaryotes, new mutations accumulate much more slowly. The primary reasons for this are prokaryotes reproduce quickly and have vast populations.

<h2> Prokaryotes V/S Eukaryotes</h2><h3>Prokaryotes</h3>

Prokaryotes are organisms consisting of cells that don't have cell nuclei or any organelles that are enclosed in membranes. It follows that prokaryote's DNA is not contained within a nucleus.

The following components could be found in a normal prokaryotic cell:

  •  The membrane enclosing and guarding the cell is known as the cell wall.
  • All of the cell's internal components, excluding the nucleus, are called cytoplasm.
  • Some prokaryotic cells have filaments made of proteins called flagella and pili.
  • A nucleoid is a cell structure that resembles a nucleus and contains genetic material.
  • A plasmid is a little DNA molecule with independent reproduction.
<h3>Eukaryotes</h3>

Eukaryotes are organisms made up of cells with membrane-bound organelles and a nucleus that contains DNA in the form of chromosomes. Eukaryotic organisms can have several cells or just one cell. Eukaryotes make up all animal life. Protists, fungi, and plants are examples of additional eukaryotes.

Distinguish between metabolism and homeostasis.
ElenaW [278]

Answer:

Metabolism refers to chemical reactions that occur within the cells of living organisms -that involve the interaction of substrates, co-factors and enzymes to obtain a product- while homeostasis refers to the internal balance within the body.

Explanation:

<u>Metabolism</u> involves a series of processes that occur in order to obtain a result or product necessary for life. Exist chemical reactions that are part of various metabolic pathways, where chemical substances are transformed into others through the intervention of specific substrates and enzymes. In metabolism reactions can be :

  • Anabolic, when necessary molecules are constructed or synthesized, such as the biosynthesis of proteins from amino acids
  • Catabolic, when a substrate is broken down to obtain a product, such as glucose to produce energy (ATP) .

<u> </u><u>Homeostasis</u><u> </u>is the maintenance of the proportion of elements for the body to function properly. It is the equivalent of internal balance, which makes use of internal regulation mechanisms.

<em> A correct functioning of the metabolic reactions guarantees an adequate homeostasis, and the balance that is required for the organism to function properly, implies a regulation of the metabolic processes that occur.</em>

Which condition is essential for natural selection to result in a new species?
RSB [31]
Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.
