Answer:
Due to vegetative reproduction, his plants are not genetically diverse.
Explanation:
Strawberry plants do not reproduce via sexual reproduction, so we can immediately eliminate the options pertaining to sexual reproduction. Now, we can take a look at the options pertaining to vegetative reproduction.
With vegetative reproduction, the "child" plant has the same genetic makeup as the parent plant. If this happens over and over, then the offspring will not be genetically diverse. Either all of the strawberry plants or none of them would be fungi-resistant. The farmer did not find any fungi-resistant plants because they all have the same genes, and therefore all do not have the genes that would make them fungi-resistant.
The answer would be 5 miles per hour, as 5x4 = 20

Answer:
The semilunar valves prevent backflow of blood into the ventricles.
Explanation:
The semilunar valves are valves found at the junction between the left ventricle and the aorta and also between the right ventricle and the pulmonary artery. They are cup-like in shape and prevent blood from flowing back into the ventricles which are the pumping chambers.
There are two types of semilunar valves. The aortic semilunar valves and the pulmonary semilunar valves. They are made up of the endocardial and connective tissue.
The closure of the semilunar valves causes the second heart sound detected on the stethoscope.
Diseases that arise from the semilunar valves are caused by its stenosis which is the narrowing of the valves and regurgitation where the heart valves can no longer hold firm enough to prevent the backflow of blood.
