The right atrium<span> is one of the four chambers of the heart. The heart is comprised of two </span>atria<span> and two ventricles. Blood enters the heart through the two </span>atria<span> and exits through the two ventricles. Deoxygenated blood enters the</span>right atrium<span> through the inferior and superior vena cava</span>
Answer:
Density is nearly 3 cabs per hectare
Explanation:
Given -
There are three three intertidal regions.
Area of each intertidal region is hectares.
Number of crab in the intertidal regions are as follows -
Intertidal region I - 7
Intertidal region I - 2
Intertidal region I - 6
Sum of crabs in all three regions is equal to
Total area of all three intertidal regions is equal to
hectares
Now density per hectare is equal to total population of crab divided by total area of all the three intertidal regions
Density
Density is nearly 3 cabs per hectare
Answer:
Hence, during infection in vivo, a noncytopathic virus may turn off the "differentiation" or "luxury" function of a cell while not killing that cell (loss of vital function). This is turn can disrupt homeostasis and cause disease

In animals, gas exchange follows the same general pattern as in plants. Oxygen and carbon dioxide move by diffusion across moist membranes. In simple animals, the exchange occurs directly with the environment. But with complex animals, such as mammals, the exchange occurs between the environment and the blood.
