Gas exchange between the air in the lungs and the blood takes place in the alveoli.

ALVEOLI:

  • Gaseous exchange is a phenomenon whereby gases (carbon dioxide and oxygen) are taken in and out of the body.

  • Carbon dioxide is a product of respiration, hence, giving out. Oxygen is a reactant, hence, taken in. Carbon dioxide and oxygen are absorbed and removed from the blood in the general respiratory process.

  • The alveoli are richly supplied with blood capillaries and are sites of gaseous exchange in some living organisms.

How is mass wasting different from other forms of erosion?
Romashka-Z-Leto [24]

Answer:

A

Explanation:

Examples of mass wasting are slides, falls, creeps, and flows.  Mass wasting processes are easily observable because they happen fast and suddenly and the changes are vividly evident in very short bit of time.   However, other methods of erosion such as mechanical and physical weathering occur very slowly and it would take many years for the changes associated wth their proceses to be vivid to the naked eye.

Explain how natural selection could lead to a change in allele frequency leading to a change in the color of the frogs.
Pie

Answer:

Due to increasing the survival.

Explanation:

The natural selection causes a change in allele frequency leading to a change in the color of the frogs because the colour of the frog helps it in hiding from predators. The population of that frog specie increases which has the ability to hide from the predators in that environment while on the other hand, the population of frog decreases which can easily be seen by the predator due to its colour so this change in allele frequency will leads to natural selection.
