B, the others are not testable under lab conditions.
The most plausible hypothesis to explain why species richness is higher in tropical than in temperate regions is that B) tropical regions have more available water and higher levels of solar radiation.
Hope this helped!!
Answer:
C. All plankton are closely related to plants.
Explanation:
Plankton are organisms found in water that exist in a drifting state. They are too small or weak to swim on their own, so they let the current or tide carry them. They are usually microscopic but include larger species as well, such as some crustaceans and jellyfish.
Phytoplankton are autothrophic plankton. This means that they produce their own food. They are primary producers and closely related to plants.
Zooplankton are heterotrophic plankton, which means that they feed on other organisms. They are animals and aren't closely related to plants.
Nekton are organisms found in water that swim actively.
Based on this information, we can conclude that statement C is the only incorrect statement.
Answer:
adaptation-the inherited characteristic that increases an organism's chance of survival and to reproduce.
fitness -the ability of an organism to survive and reproduce in its environment
In humans, new neurons are continually born
throughout adulthood in two regions of the brain:
<span>·
</span><span>The subgranular
zone (SGZ), part of the dentate gyrus of
the hippocampus.</span>
<span>·
</span><span>The striatum;
however the adult-born neurons are a type of interneuron,
not a type that projects to other brain areas.</span>[5]
<span>In other species of mammals, particularly rodents,
adult-born neurons also appear in the olfactory
bulb. In humans, however, few if any olfactory bulb neurons are
generated after birth.</span>
