If a forest fire explodes in the thousands of acres of trees then the population of animals and birds decreases in the surrounding forests.
<u>Explanation:</u>
The shelter and food for animals will be affected to the most. They also feel difficult to breathe during a forest fire.
Some animals may suffer to escape from the forest fire as they may be isolated from parents.
Forest is the home for many plants, animals and birds. If the trees start burning, then these animals and birds quickly replace their shelter to somewhere safe.
As the forest has been providing the necessary food and other elements to the surrounding forest’s animal, so they too find a better place with good resource. Hence the overall population of animals and birds decrease.
A white blood cell engulfing foreign materials is more likely to carry out Endocytosis.
Explanation:
Endocytosis is the process by which a cell takes up a macromolecule into is cytoplasm by forming a vessicle.
In the question two cases are given, both the cases involve the formation of membrane bound vessicle but in different ways.
The excretion of hormones involves the movement of molecule outside the cytoplasm. This process is exocytosis.
The engulfment of an antigen by WBC involves taking up of molecule within the cell so that it can be killed and digested. Thus in this case Endocytosis is more likely to occur..
Electron transport trains create a concentration gradient of hydrogen ions outside the mitochondria and fewer inside the mitochondria and creates energy(ATP) by diffusing the hydrogen ions back in
