Cup nest.
Adherent nests.
Platform nests.
Earth-hole nests.
Ground and mound nests.
Scrape nests.
Explanation:
Semen creates a(n)<u>alkaline </u>environment for sperm to safely travel through both the male and female reproductive tracts.
In the field of biology, semen can be described as a white, slippery fluid that is released from the male reproductory organ. Semen is also referred to as the seminal fluid.
The semen of males carries the sperm cells which are required for the fertilization of the female egg. The conditions should be favorable for the process of fertilization to occur.
The natural atmosphere of the vagina of a female is acidic in nature. The sperms need a neutral environment for survival. Hence, the semen is produced alkaline in nature to prolong the lifetime of sperm cells. The alkalinity of the semen neutralizes the acidity of the vagina.

The answer is They are able to produce ATP molecules to help power metabolic processes
The endosymbiotic theory explains that mitochondria and chloroplasts descended from the same type of bacteria. According to the endosymbiotic theory, a host cell ingested symbiotic bacteria. The bacteria later specialised into mitochondria or chloroplasts. The evidence for this theory is that mitochondria and chloroplasts, similarly to bacteria, have their own circular DNA and replicate in a manner similar to some bacteria cells. they have a double membrane that resembles that of some ancient prokaryotic cells and their inner membranes contain the same enzymes as prokaryotic plasma membranes.
However, chloroplasts do not produce ATP molecules, they are involved in the process of photosynthesis. On the other hand, mitochondria are able to produce ATP molecules to help power metabolic processes. So, this choice cannot be correct.
