Answer:

The statement is false

Explanation:

Rocks make many layers on the surface on earth which make the earth crust. Minerals are the ingredients which are responsible for making rocks and every rock is made up of one or a mixture of minerals and these minerals are made up of one or more elements.

The common mineral that is responsible for making rocks are amphibole, olivine,  calcite, mica, feldspar, and quartz. So when one or more than one of these minerals aggregate it form rocks. The common rocks are limestone, granite,  sandstone, and basalt. Therefore the statement is false.

The ovarian cycle describes the monthly events of a post-pubescent ovary that causes a small number of primary follicles to grow
Damm [24]

Answer:

The ovarian cycle regulates endocrine tissue preparation, and egg release in female body.  

The first half of the ovarian cycle as the follicular process. Slowly growing rates of FSH and LH are causing follicle development on the ovary surface. This cycle makes the egg primed for ovulation. As the follicles develop they start releasing estrogens and low progesterone levels. Progesterone locks the endometrium in order to help ensure pregnancy. It takes about seven days to travel ovum through the Fallopian tube and to get implanted in uterus. There are 30-60 cells at this point of evolution, called the morula. If there is no pregnancy implantation the lining would be sloughed off. estrogen levels increase after around 5 days, and the menstrual cycle enters the proliferative process. The endometrium starts to regrow, replacing the weakening blood vessels and glands at the end of the last cycle.

Alexeev081 [22]

The answer is they produce endospores.

Explanation:

The endospores are dormant, non-reproductive, tough bacterial spores that ensure the survival of bacteria in adverse conditions.

During the environmental stress, such as starvation, desiccation, radiation and chemical treatment many bacteria form dormant endospores. These endospores germinate again when the conditions become favorable.

Hence, if drought conditions lead the stream to dry up, the bacteria that live there would produce endospores to survive.
