murzikaleks [220]

Answer:

The correct answer will be option-B.

Explanation:

Meiosis is a type of cell division which proceeds in two stages: meiosis I and meiosis II and result in the formation of four daughter cells.

The meiosis I is known as the reductional division as two daughter cells are formed with reduced ploidy level that is haploid cells from diploid cells.  The cells formed contains chromosomes with two chromatids as the DNA amount gets doubled after the DNA synthesis.

Thus, Option-B is the correct answer.

Which is the term for numbers that appear in the chemical formulas of some compounds?
iogann1982 [59]

It is called subscript indicating the number of atoms.

Explanation:

The chemical compound is formed by two or more elements.

The compound is formed by the sharing, accepting or donating the electrons.

The compound formed by two elements will have different valencies of cations and anions.

In chemical formula of compound specific number of atoms of each element are present.

eg: H2O (2 atoms of hydrogen bonded with one atom of oxygen)

       NaCl  (1 atom of sodium and one atom of chloriine are bonded.)

     NaHCO3 ( 1 atom of sodium, 1 atom of hydrogen, 1 atom of carbon and 3 atoms of oxygen.)

Which of the following are contributing factors to the extinction of species?
meriva

Answer:

Deforestation

Climate Change

Invasive Species

Explanation:

Seventy percent of the Earth's plant and animals dwell in forests, and deforestation affects them directly. Once their habitat is lost, they are on their way to extinction.

Climate change also causes extinctions not only as a result of species intolerance to high temperature, but more commonly via a variety of related factors that alter a species’ interactions with other species.

Invasive species invade foreign territory. They use resources that the other species depend on. Then naturally one of the species will die off.

What is the biological significance of the temperature at which the amylase
kati45 [8]

Answer & explanation:

Amylase is part of enzymes, a group of large peptide molecules (formed by amino acids) whose role is to catalyze reactions in order to facilitate the synthesis of other biological molecules.

Amylase is found mainly in saliva (in the form of salivary amylase, or ptialin), acting in the breakdown of starch and glycogen in foods, reducing them to smaller particles, facilitating their digestion and absorption.

The action of enzymes depends on certain specific conditions, called optimal conditions. In the case of <u>amylase</u>, it depends on an optimum pH of 7 (neutral) and an optimum temperature of approximately 37 ° C.

This enzyme can still act between 35 ° C and 40 ° C, but below 35 ° C it is inactivated, preventing its functions from being performed, and above 40 ° C it suffers denaturation, causing changes in its structures.

Thus, it is concluded that the <u>temperature</u> (under optimal conditions) is important for enzymes because it keeps their actions and structures in proper operation.
