Identical and obviously duplicated gene sequences have gotten from one chromosome to another by chromosomal translocation.
In terms of genetics, a translocation takes place when chromosome fragments and the (often two) fragmented portions reassociate with other chromosomes. For the diagnosis of several genetic diseases and syndromes, the finding of chromosomal translocations can be crucial.
Multigene families are groups of related or identical genes that have developed by gene duplication. It is thought that a single ancestral gene was duplicated and varied to create multigene families. The multigene families that code for actins, hemoglobins, immunoglobulins, tubulins, interferons, histones, etc. are a few examples.

#SPJ4
True, because the kidneys filter out waste in most living things.
Answer;
Adrenal glands
Explanation;
-When confronted with a stressor, the adrenal glands respond by producing stress hormones, including catecholamines, cortisol, and epinephrine.
-In response to acute stress, the body's sympathetic nervous system is activated due to the sudden release of hormones. The sympathetic nervous systems stimulate the adrenal glands triggering the release of catecholamines, which include adrenaline and noradrenaline.
-These "stress hormones" cause several changes in the body, including an increase in heart rate and blood pressure.
Answer:
Basically, when organisms combine stuff to make different stuff and get rid of other stuff.
Explanation:
cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.
Answer:
Types of Transpiration
There are three different types of transpiration in plants:
Stomatal Transpiration
It is the evaporation of water from the stomata of the plants. Most of the water from the plants is transpired this way. The water near the surface of the leaves changes into vapour and evaporates when the stomata are open.
Lenticular Transpiration
Lenticels are minute openings in the bark of branches and twigs. Evaporation of water from the lenticels of the plants is known as lenticular transpiration.
Lenticels are not present in all the plants. A minimal amount of water is lost through lenticels.
Cuticular Transpiration
It is the evaporation of water from the cuticle of the plants. The cuticle is a waxy covering on the surface of the leaves of the plants. About 5-10% of the water from the leaves is lost through cuticular transpiration. During dry conditions when the stomata are closed, more water is transpired through the cuticles.
