After the Cretaceous–Paleogene extinction event wiped out the non-avian dinosaurs (birds being the only surviving dinosaurs) and several mammalian groups, placental and marsupial mammals diversified into many new forms and ecological niches throughout the Paleogene and Neogene, by the end of which all modern orders had appeared.
Answer:
(Answers will vary.)
In many forest ecosystems, squirrels and chipmunks compete for acorns and some other resources. However, they don’t have the exact same niches. Squirrels nest in trees, while chipmunks live underground. These species don’t compete with each other for mates either. Thus, squirrels are in interspecific competition with chipmunks.
All squirrels in a particular ecosystem share the same niche. The same is true of all chipmunks. So, both of these species are in intraspecific competition. Competing with an individual from the same species is harder than competing with members of other species. For example, squirrels compete with other squirrels for not only food (acorns), but also shelter and mates. However, they also compete with some other species, such as deer and acorn weevils, for acorns. Furthermore, they are both prey for many of the same predators, such as hawks, raccoons, foxes, and weasels.
Explanation:
The Coriolis effect<span> is caused by a combination of the inertia of moving air and the rotation of the Earth. Air tends to move from high pressure to low pressure in a straight line, but the rotation of the Earth means that, to an observer at one spot on its surface, the moving air appears to turn.

His genotypes are X to the power of H and X to the power of h the second numbers are exponents so it goes X to H and X to h i hope this makes sense i couldn't make them into exponents but i tried :)
I would assume it is choice b.
because in the summer there are more hours of light, and n the winter there are less.
