Answer:
The correct answer would be B. Lungs, left ventricle, capillaries, veins, right ventricle.
It can be explained with the help of double circulation.
The oxygenated blood from the lungs is transported to the left atrium with the help of pulmonary veins.
The left atrium then passes the oxygenated blood to the left ventricle which passes the blood to all parts of the body via aorta.
The artery then divides into fine capillaries which supply cells and tissues of the body.
The cells use the oxygen and produce carbon dioxide as the byproduct of cellular respiration.
The blood is now termed as deoxygenated blood which is carried out by veins.
Vein transport this blood to the right atrium of the heart which passes the same to the right ventricle.
Left ventricle then pumps the blood towards lungs for oxygenation.
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.
