Answer:
A
Explanation:
The pulmonary artery carries de-oxygenated blood from the right ventricle of the heart to the lungs. It is the only artery that carries de-oxygenated blood. This blood is usually from the tissues and has a lot of carbon dioxide from the cellular respiration of cells around the body. The blood is pumped to the lungs to be oxygenated and the carbon dioxide expelled.
Answer:

Explanation:
Symbiotic relationship is a type of relationship between two organisms in which the both of them gain something positive from each other. A good example is the relationship between the cattle and egret. The egret helps in grooming the cattle and the cattle in return provides food for the egret.

Think it would be True!!!
Answer:
In harsh winter, usually there's less food, therefore, rabbits will not be able to find enough food and the population of rabbits will decrease.
The answer is meiosis.
In meiosis, this process produces 4 daughter cells which are all genetically different to each other and their parent cell. They have only half of the chromosomes. This is because, at one point in the process before the cells divide, parent do not copy their genetic information, which ends up each daughter cells only receiving half of the chromosomes after division.
The daughter cells are also said to be haploid, and in human, these cells are usually gametes, which are for reproduction, so that after 2 of these haploid cells join together, the correct amount of chromosomes can be restored.
