<h2>Exhaustion stage of general adaptation.</h2>
Explanation:
The final stage of general adaptation theory is known as exhaustion stage.
The general adaptation is has been divided into three stages- Alarm stage, resistance stage and exhaustion stage.
The theory of adaptation describes the physiological changes that an organism undergoes when it is exposed to stress.
The first stage,which is the alarm stage which is characterized by the burst of energy and the stressor acts as a stimulus.
The second stage is the resistance stage when the organism develops the resistance against stressor.
The last stage is the exhaustion stage when the energy is sufficiently depleted and the final adjustment is attained.
Answer:
9:3:3:1
Explanation:
If alleles of two genes separate randomly during anaphase-I of meiosis, some new combinations of the alleles are formed in the gametes. A heterozygous genotype for two loci (let's support TtRr) produces a total of four types of gametes in 1:1:1:1 ratio (TR, Tr, tR, and tr). The random fusion of these gametes from two double heterozygous parents (TtRr x TtRr) gives a phenotype ratio of 9:3:3:1. Here, 9/16 F2 progeny exhibit dominant phenotype for both loci while 1/16 exhibits recessive phenotype for both the genes. Rest 3/16 and 3/16 F2 progeny express dominant trait for one gene and recessive for the other.
Answer:
Yes
Explanation:
At room temperature, exposed elemental mercury can evaporate to become an invisible, odorless toxic vapor. ... Elemental mercury is an element that has not reacted with another substance.
I recommend reading a passage about it. Hope this helps!
