Answer:
A. The use of only the most productive breeds improves genetic diversity.
Vision is the least developed of a newborn baby's senses. <span>The visual capacity of the baby develops progressively in the first 8 months. From then on, the baby's vision will be as good as that of the adult. Although at birth, the eyes of the newborn have the physical ability to see without problems, your brain is not yet ready to process all that information; that's why he sees everything blurred. With the development of the brain, your visual ability improves.</span>

Answer:
It will depend on the type of virus that infects the host's cells. For example, if it is a poliovirus, the answer will be <em>"D. poliovirus protein coats and poliovirus genetic material"</em>
Explanation:
A virus is composed of genetic material encapsulated by a protective coat protein (capsid). The genetic material of a virus can be either DNA or RNA and single-strand or double-stranded (either DNA or RNA). Moreover, the capsid may be surrounded by an additional spikey coat known as envelope. During infection, a virus invades the host´s cells to replicate both its genetic material and its proteins (they use host cellular machinery to synthesize new viral proteins). Depending on the type of virus, they can integrate and replicate its genetic material into the host genome (DNA viruses and RNA retroviruses) or replicate its genetic material outside the host genome (RNA viruses in general).
Answer:
a) Increased heart rate, increased blood pressure, increased respiration rate.
Explanation:
When a person do any physical activity like running, jogging, cycling, swimming and stair climbing, the heart rate, blood pressure and respiration rate of a person are increased because due to physical activity, the body needs more and quick oxygen and energy. This oxygen is provided by heart through pumping of blood and energy is released due to the breakdown of glucose molecules that occurs in mitochondria of the cell in the process of respiration. For providing oxygen and energy quickly, blood pressure of the body is increased.
