Answer and Explanation:
Biogeographic distribution is the large-scale geographic pattern in the distribution of species, and the causes and history of this distribution. The evolution of analogous structures is called convergent evolution which occurs due to different organisms exploiting the same environment.
The ancestors of modern mammals arose in the northern hemisphere and migrated in three major directions before the drift. Separation of the continents isolated the animals bringing about different patterns of evolution.
Answer: The earth is made up of three different layers: the crust, the mantle and the core. This is the outside layer of the earth and is made of solid rock, mostly basalt and granite. There are two types of crust; oceanic and continental. Oceanic crust is denser and thinner and mainly composed of basalt.
Explanation:
When we're sick, our noses are often blocked with mucus. Also, the tissues inside our nose can become swollen and inflamed. This prevents us from smelling properly. Because your sense of smell is so tied to your sense of taste, if you can't smell things properly, you won't be able to taste them properly, either.
It would be false. Because a hydrogen bond is characterized by an electrical attraction and a hydrogen is attracted to weakly negative atoms. So it doesn't transfer its electron.
