Explanation:
Water enters the atmosphere through three processes: evaporation, transpiration, and sublimation.
Answer:
Attachment stage
Explanation:
Viruses are organisms that are incapable of replicating on their own, instead they infect a living host in order to make use of its transcriptional, replication and gene expression abilities to multiply. This process of infection characterizes the reproductive life cycle of the viral cell.
Normally, viruses are specific when infecting their hosts but they generally commence the infection cycle with ATTACHMENT. In this stage, the viral cell with the aid of its proteinous capsid binds to specific receptor site on the cell membrane of its host cell before making entry by incorporating its genetic material.
Answer:
The correct answer is option d.
Explanation:
An illustration of epigenetic change is a microbe, which can stimulate modifications in the host DNA, causing suppression of defenses or weakening of individual cells. Epigenetic changes modify the physical composition of DNA.
One of the examples of epigenetic change is DNA methylation. DNA methylation refers to the supplementation of methyl group, which inhibits some of the genes from getting expressed. One of the conditions of DNA methylation is cancer.
In the majority of cancer, the tumor cells go through global hypomethylation. The tumor suppressed genes seem to turn highly methylated in the conditions of cancer.
The correct answer is B. Hypothalamus.
Explanation
The hypothalamus is a part of the brain that is located below the thalamus, it is an area of the brain where several and very important homeostatic regulatory functions of the organism are integrated. Its main function is to link the autonomic nervous system with the endocrine system. Other functions are to control body temperature, control thirst and urine production (water balance in the body), control food intake, control uterine contractions and milk ejection in mammals, the coordination of the nervous system Autonomous, which affects smooth muscle and cardiac activity, influences behavior and expression of emotions. Therefore, the correct answer is B. Hypothalamus
