This question has choices namely:

preload
afterload
contractility
cardiac reserve

The correct answer is preload. Preload is the filling capacity of the heart and it corresponds to the volume of the blood that fills the ventricles during a cycle. In this case, the left ventricle needs to accommodate the increased volume from the right heat therefore increasing the filling capacity therefore the preload. 

Afterload is the pressure that the heart needs to overcome to pump the blood. In the right ventricle, the pressure is the pulmonary arteries wherein the right ventricle needs to contract and generate a pressure greater than the pulmonary arteries for the blood to move out the ventricle. Similarly, in the left ventricle, the source of pressure is the aorta and the left ventricle needs to contract and generate a pressure greater than the aorta and the systemic circulation for the blood to move out of the ventricle. 

Contractility is the force of contraction of each ventricle in one cycle.

C. Parasitic.

D. Both a and b.

E. All of the above.

The correct option is all of the above.

Explanation:

Angiosperms are flowers and seed producing plants and their seeds are enclosed in ovary.The angiosperms are vascular seed plants in which the ovule (egg) is fertilized and then develops

into a or become a seed in an enclosed hollow ovary. They are most diverse and largest group of animal kingdom.

Some angiosperms are autotrophs that uses carbondioxide, water and sunlight energy to produce their own food and releases oxygen.

Examples include maize, rice..

Some angiosperms are saprophytic which obtain energy from dead and decaying matter in the soil. They form a symbiotic relationship with fungi. Example is Neottia.

Some angiosperms are parasitic and they attach to their host through haustoria their by feeding on the host and causing harm on the host.

Why are the cells produced by meiosis considered gametes?
BigorU [14]
Gametes are cells used to sexual reproduction. they are haploids and that means they have just one set of chromosomes (most of the cells of our body have 2 sets). that kind of cells is produced mainly by meiotic division of the gamete's stem cell (called oogonium or spermatogonium) and that's why meiosis usually leads to the production of gametes. gametes are haploids so that they could combine (egg with sperm cell) and create the whole new organism (adult organism is almost always diploid).
