The gametes are formed by cellular reproduction process of meiosis.

Meiosis is the cell division that splits the chromosomes into half the number resulting in four haploid cells. The daughter cells are completely different from the parent cell.

Hence the option Meiosis is the right answer

If the pair of materials listed below were rubbed together, give the charge that each would have in the same order as listed. us
const2013 [10]

Answer:

Simply put, the property of electron affinity refers to the relative amount of love that a material has for electrons. If atoms of a material have a high electron affinity, then that material will have a relatively high love for electrons. This property of electron affinity will be of utmost importance as we explore one of the most common methods of charging - triboelectic charging, also known as charging by friction or rubbing.

Suppose that a rubber balloon is rubbed with a sample of animal fur. During the rubbing process, the atoms of the rubber are forced into close proximity with the atoms of the animal fur. The electron clouds of the two types of atoms are pressed together and are brought closer to the nuclei of the other atoms. The protons in the atoms of one material begin to interact with the electrons present on the other material

A color-blind (X-linked recessive) human with Klinefelter syndrome has parents both of whom have normal color vision. 4a. From w
sineoko [7]

The extra X chromosome is received from mother.

<h3><u>Explanation</u>:</h3>

Klinefelter's syndrome is the condition of chromosomal aberration where the person has an extra X chromosome. This means the genotype of the person is 44+XXY and the total chromosome number is 47. This condition is achieved due to inappropriate meiotic division and one of the sperm or ovum has the an extra X chromosome.

Here both the parents are normal in terms of colour vision. So the father cannot have the gene of colour blindness because if it was present, then father would have been colour blind because he has only one X chromosome per cell. So its present in mother who is heterozygous in terms of colour blind gene. So the extra X chromosome also came from her which made the presence of two defective X chromosomes in the offspring and made it colour blind.

After examining the fossil record, scientists have determined that scorpions today are much smaller than their extinct ancestors
BabaBlast [244]

Answer: C. scorpions have changed as a result of natural selection

Explanation:

The text tells us that scorpions today are now smaller than they were in the past. This means that the scorpions have changed since then i.e. they have evolved.

The primary reason for evolution is natural selection which refers to a situation whereby only the organisms that are better adapted in their species survive.

The conclusion that can be drawn from this research therefore is that we have smaller scorpions today because they stood a better chance of survival than the larger ones and so survived whilst the larger ones died out.
