Answer:
Blood clotting normally occurs when there is damage to a blood vessel.
Explanation:
Platelets immediately begin to adhere to the cut edges of the vessel and release chemicals to attract even more platelets. A platelet plug is formed, and the external bleeding stops.
Next, small molecules, called clotting factors, cause strands of blood-borne materials, called fibrin, to stick together and seal the inside of the wound. Eventually, the cut blood vessel heals and the blood clot dissolves after a few days.

Answer:
All of the above are possible proximate causes of the behavior
Explanation:
Cats have reproductive organs, these organs go through a normal cycle, called heat cycle, that let reproduction to occur. During this cycle, they have hormonal fluctuations that mean that their body is ready to breed.
During the heat cycle, cats have several behaviors and signs such as spraying urine, rolling on the floor and scratching at doors begging to go outside. When a female cat is in heat, she is likely to urine more frequently and even spray urine on objects, <u>to let any nearby male cats know that she is ready to be mated with</u>. The urine contains pheromones and hormones, signals of her reproductive status to other male cats.
In the wild, females cats pee on trees or objects <u>to find a male cat to mate with</u>. This is why one might infer that <u>female cats did this in the past </u>and the domestic cats inherited this behavior.
The short segments of newly assembled DNA from which thelagging strand is built are calledOkazaki fragments. As replication proceeds and nucleotides are added to the sugar end of the Okazakifragments, they come to meet each other. The whole thing is then stitched together by another enzyme called DNA ligase.
