Answer:

e. The statement is true for meiosis I only.

Explanation:

When we talk about homologous chromosomes, we talk about two chromosomes forming a pair of genes. One comes from the mother, and one comes from the father in sexual reproduction.

The random segregation of chromosomes is what we call the result of crossing over during meiosis I, and is what generates genetically unique individuals in each reproduction.

garik1379 [7]

Answer:

The correct answer is- A) two, B) yes, the number is the same as monosaccharides.

Explanation:

There are three atoms are present in a molecule of water which includes two atoms of the hydrogen and one atom of the oxygen. The hydrogen atom is two times larger in the number of the oxygen atom in a single molecule of the water.

In monosaccharides, the ratio of the atoms of carbon, hydrogen, and oxygen is 1:2:1 which means one hydrogen atom would be twice in the number of the carbon and oxygen atoms in a single molecule of monosaccharide molecule.

Thus, the correct answer is - A) two, B) yes, the number is the same as monosaccharides.

Which is most likely not a beneficial contribution made by biologists?
Elodia [21]

Answer:

The activity that does not represent a beneficial contribution made by biologists is to improve the durability of non-stick coatings (option C).

Explanation:

The development and improvement of non-stick coatings does not correspond to an activity within the field of biology. Anti-stick coatings, such as Teflon, are products developed through industrial activity.

Biologists' activity is focused on living organisms and their interaction with the surrounding environment. Improving arable soils and food quality, as well as increasing life expectancy are activities that fall within the field of study of biology and its related disciplines.
