Fusion is the process which sun use to produce energy
Answer:
In the natural world, limiting factors like the availability of food, water, shelter and space can change animal and plant populations. Other limiting factors, like competition for resources, predation and disease can also impact populations.
Explanation:
Answer: True
Explanation: Ion channels are very specific and are voltage gated channels. They are highly specific and selective for particular ions only.
Example: Some of the channels allow the flow of potassium ions but do not allow sodium ions to cross the membrane to maintain the concentration.
Some of the positive ion channels allow only the movement of positive ions and no negative ions. These channels are not always open and opens only when there is a concentration gradient.
Answer:
Letter b. Gluconeogenesis
Explanation:
Immediately after eating we use the sugars in the food and utilize for energy and last a couple of hours. After that and about 15 hours later our body uses the energy stored in the liver in the form of glycogen, a process called glycogenolysis, that is the action of breaking the glycogen to free the energy. After 24 hours, the body starts to use another molecule for energy like fatty acids and start to synthesize glucose from other precursors, this process is called gluconeogenesis, and fuels the vital organs like the brain to maintain its function.
