Answer:
Adverse heart conditions do not occur in isolation. It is usually accompanied by other risk factors, like coronary artery dysfunction, diabetes, high blood pressure, etc.
In addition to the above, the following factors are indicative of left-sided heart failure:
- Shortness of breath caused by the collection of fluid in the lungs. Shortness of breath usually becomes pronounced upon physical exertion
- An increase in the girth of the torso (mainly the abdomen) due to ascites which is the buildup of fluid in the abdomen.
- engorged scrotum (in males of course)
Explanation:
Left-Sided Heart Failure is simply the inability of the heart to pump oxygen-rich blood into the body.
Blood filled with oxygen is moved from the lungs to the atrium on the left and then to the left ventricle. The blood is then pumped from the ventricle on the left to other parts of the body by a contracting and relaxing action. Left-sided heart failure can be classified into two:
- Systolic Failure and
- Diastolic Failure
1. Systolic Dysfunction: When the left ventricle can no longer shrink properly, the pressure with which the heart can pump enough blood into circulation is reduced.
2. Diastolic Dysfunction: This occurs when the left ventricle can no longer relax as it ought to due to the hardening of the muscle.

Answer:
A and C are correct! :)
Explanation:
A is correct because the poachers are not intentionally trying to increase the number of tuskless elephants, but they are accidentally doing so because elephants without tusks are less likely going to be killed by them.
C is correct because where the Rams with smaller rams are more likely to survive.
The body cell has more genetic information. A gamete only has half the information of a body cell. So when two gametes combine (a sperm and an egg), together they provide the child with all the genetic information needed for its body cells.
Hope this helps :)
