The Answer is B................
Answer:
The type of evidence is<u> Mechanical incompatibility.</u>
Explanation:
Copulation is often impossible between different animal species because of the incompatible shape and size of the genitalia.It is called mechanical incompatibility.
This isolation prevents species that diverge from interbreeding thus they lo longer able to mate with each other.
Here morphological difference takes place which ultimately leads to behavioral isolation and thus no mating takes place.
Here snail can not mate because their morphological structures are incompatible.
An observation may generate a scientific question, which may lead to a hypothesis. The hypothesis can be tested the experimentation. The results of experimentation lead to changes in scientific knowledge.
Answer:
A. humans going underwater and exhaling
Explanation:
The dissolved oxygen in water refers to the amount of oxygen that is found in water. However, there are various ways that oxygen dissolves in a body of water, these includes;
- Photosynthesis of aquatic plants: Oxygen is the waste product of the photosynthetic process carried out by green plants. Hence, when aquatic plants undergo photosynthesis, oxygen from them tend to dissolve into water.
- Diffusion from the atmosphere: Oxygen from air or atmosphere also dissolves in water
- aeration as water moves over rocks and debris, and from wind and waves
However, humans do not exhale oxygen but carbon dioxide, hence, it is not a source of dissolved oxygen
Transpiration occurs when plants take in water through the roots and release it through the leaves, a process that can clean water by removing contaminants and pollution.
