Answer:
Spermatogenesis is stimulated by FSH acting on sertoli cells.
Explanation:
Spermatogenesis is the process by which spermatozoa grow and develop from germ cells into mature form. There are many hormones that are involved in this process and one of them is FSH (Follicle Stimulating Hormone). Another factor that play a vital role in the process are sertoli cells.
The FSH stimulates sertoli cells to release androgen-binding protein into the lumen portion of seminiferous tubules. The sertoli cells are the epithelial supporting cells that are located inside the seminiferous tubules. The sertoli cells are responsible for keeping the germ cells nourished and for extracting excess cytoplasm from newly formed spermatozoa cells just before they are released into the lumen of the seminiferous tublules.
Answer:
The offspring with large, deeply colored flowers is produced from vegetative reproduction which the offspring with small, lightly colored flowers is produced from sexual reproduction.
Explanation:
Reproduction of a plant is the propagation of that plant and it occurs via the sexual or asexual means. The asexual means also called vegetative reproduction involves only one parents and the resulting offspring grows from a part of this parent. Sexual reproduction involves the union of sex cells from two parents (male and female).
In asexual or vegetative reproduction, the offsprings are genetically identical to the parent they emanate from while in sexual reproduction, the offsprings can be genetically different due to the process of recombination that occurs in gametes during their formation (meiosis). This allows for genetic variation among the offsprings.
Therefore, the offspring that resembles the parent i.e. large and deeply colored was likely produced by the vegetative or asexual means of reproduction while the offspring that exhibited a different characteristics from the parent was produced from sexual reproduction.

Answer:
The top blank is atmospheric CO2, the right blank is combustion (i think, I can't see the bottom), the left blank is plants use CO2, the bottom blank is organisms release CO2.
