An example of serious poaching problems is the diminishing population of Tigers.
For example in India, this has severely affected the survival-probability of tigers. There were 20000 Tigers in India in the 20th century, and now there are only 3000. This shows the severity of the problem. The government is now taking serious steps against the poachers.
Answer:
Shelter belts.
Explanation:
Trees are one of the important natural resources of the earth. Trees perform different important functions like purifying air, production of oxygen, reduction of the amount of carbon dioxide and consumptive use.
The shelter belts may be defined as the vegetative barriers producted by planting the trees in the specific rows. They are mainly designed to reduce the wind effect, its speed. The shelter belts also provide sheltered areas of the windward.
Thus, the answer is shelter belts.
Answer:
D) Vasopressin
Explanation:
Neurohormones are defined as those hormones which are reeased from the and secreted in to the blood.
Vassopressin is also a neurohormone released from the hypothalamus and secreted by the neurohyphophysis also called posterior loop of pituitary gland in to the blood and then act on the target organ. Vasopressin is also called anti diuretic hormone its function is to maintain osmolality (the concentration of dissolved particle such as salt in the serum).Its main site of action is kidney to absorb water and not to allow much water to loss trough the urine.Thus it help in maintaining water level and mineral maintenance in the body (homeostasis)
The answer is a C3 fixation.
Plants are located in different regions with a different condition, so they had to adapt the carbon fixation. There are three types of carbon fixation in plants - C3, C4, and CAM fixation. C3 and C4 plants open their stomata during the day while CAM plants open stomata during the night.
Plants in arid locations use CAM carbon fixation because of adaptation to water deficiency. In CAM plants, stomata are closed during the day and water loss is reduced. In the night when is colder, stomata open and carbon dioxide enters through stomata. In C4 carbon fixation, there is also adaptation to high temperatures thanks to enzymes that increase the rates of photorespiration, unlike the C3 fixation.
The answer to this question is hematocrit. Hematocrit is the
volume of red blood cells in the blood. Hematocrit is also known as packed cell
volume. Hematocrit levels of a person also notes health problems. When the level
of hematocrit is high it can cause sleep apnea, dehydration, COPD, and even
falling of plasma levels.
