If mitosis stopped in your body, what effects would you see most rapidly? Which tissues would
kogti [31]

Cell division during mitosis is necessary for replacing damaged or dying cells, as well as repairing damaged or worn-out cells that occur naturally. The main mechanism behind growth is this kind of cell division.

<h3>What are the consequences if mitosis stopped in the body?</h3>

Without mitosis, there wouldn't be any cell division or growth. The fact that genetic information cannot be passed on is most essential. All cell processes would be significantly impacted.

You might also suffer serious consequences, as your heart would have to beat by itself, among other things. Your bones or your brain wouldn't be immediately impacted, but your blood cells would.

Therefore, Every cell in your body would stop replicating itself if mitosis halted, which would induce a heart attack.

makkiz [27]

Answer;

Wundt; introspection

Describing the experience of a snowflake melting on one's tongue as "cold . . . Wet . . . Tingly . . . Slightly metallic in taste" echoes Wundt's method of introspection.

Explanation;

The pioneering psychologist Wilhelm Wundt used a method called introspection to enable subjects to examine their own mental processes. introspection is used to describe a research technique that was first developed by psychologist Wilhelm Wundt.

Introspection is the examination of one's own conscious thoughts and feelings. In psychology, the process of introspection relies exclusively on observation of one's mental state, while in a spiritual context it may refer to the examination of one's soul.

Attached earlobes are recessive to free earlobes. What genotypic ratio is expected when an individual with attached earlobes mat
Marianna [84]

Answer:

C

Explanation:

This is a monohybrid cross between involving a gene coding for earlobe. The allele for free earlobe (F) is dominant over that of attached earlobe (f).

N.B: let F represent the gene involved.

A genotypic ratio is the ratio derived from the offsprings based on the actual genetic make-up and not based on their phenotypic appearance as in phenotypic ratio.

A homozygous individual is an individual having the same kind of alleles for a gene while a heterozygous individual is one that has two different alleles i.e. combination of the dominant and recessive allele.

The monohybrid cross is between an individual with attached earlobe (ff) i.e. homozygous recessive individual. (Note that, a recessive trait will only be expressed in a homozygous state) and a heterozygous free earlobeb individual (Ff). (See attached picture). Ff × ff

The resulting four offsprings will

be expected to have only two distinct genotypes i.e heterozygous (Ff) and homozygous recessive (ff) in an equal ratio i.e. 2:2 ~ 1:1
