pangea
Explanation:
once all of the world was connected and we call that pangea then over time the continental plates moved making the earth formation we know now. the theory is that could the dinosaurs have moved while pangea was still a thing.
The underlying assumption of the Harrod-Domar growth model is that
Growth is mainly determined by capital accumulation through savings
The Harrod-Domar model is a model of economic growth.<span> According to the
Harrod-Domar model, economic growth depends on two important factors, the
saving ratio and the capital output ratio.</span>

The correct answers are:
b. Human influenza a virus evolves escape variants, resulting in a distinctive cactus-shaped phylogeny.
All types of Human influenza viruses evolve to escape immunity induced by prior infections and vaccinations.
c. Measles experiences strong selection for escape variants, resulting in a phylogeny similar to a nonpathogenic species.
As a result of measles infection, specific antibody and CD4 and CD8 T cell responses are generated and contribute to virus clearance and protection from reinfection.
Chemotherapy is a term which we usually related to the treatment of cancer. In cancer the malignant cell keeps on dividing themselves and also infect the near by cell to enter into a phase of no restrictive division. In chemotherapy, a drug or medicine either individually or in combination with other medicines is either directly introduced in the blood or is injected only on the targeted cell. The chemotherapy interacts with the cell division process of the cell directly or indirectly. In the direct process the cell division process either mitosis or meiosis is impaired or the essential hormones or enzymes required for cell divisions are attacked through cytotoxic drug. It also inhibits cell division through apoptosis strategy where the cancerous cell starts dividing themselves. The chemotherapy process is to be done regularly over a certain period of time. Usually the treatment course occurs from a day to few weeks’ time. The dosage of chemical is given either orally or injected into the body fluid or either through intravenously.
Apart from benefits there can be several side effects of chemotherapy:
a) A patient may get pucky feelings and in some cases may have nausea or vomiting
b) There are also chances of hair loss.
c) It can also adversely affect the skin, as it may get dry or oversensitive.
d) The blood platelet count may decrease
e) There can be chances of hearing and vision impairment.
1. The given blank can be filled with vestibular nerve.
The vestibular nerve in humans conducts sensory information conducted by the vestibular hair cells situated in the utricle and the saccule, that is, the two otolith organs, and the three semicircular canals through the vestibular ganglion. It relays information to the brain about balance.
2. The correct answer is option b, that is, the vestibular sense may be capable of sensory adaptation.
The awareness of the movement and the balance of the body are controlled by the vestibular system. The vestibular senses, that is, the feelings of gravitation and movement and rotation of the body originate in the inner ear. The sense organs are the cells of the hair, which transmit signals over the auditory nerve.
