What takes place when you inhale and exhale ?

Answers

When you inhale and exhale, you actually breathe. When you inhale, your intercostal muscles between ribs and diaphragm contract. This increases the space in chest cavity so your lungs can expand and the air enters the lungs. When you exhale, intercostal muscles and diaphragm relax reducing the space in the chest which leads to removing the air from the lungs.

Which phrase best summarizes the theory of evolution by natural selection? A.
Only the strongest animals survive.
B.
Populations change over long periods of time.
C.
Life must come from other life.
D.
Parent organisms pass on traits they have acquired during their lifetime.

Answers

Answer: A. Only the strongest animals survive.

The theory of natural selection - the survival of the fittest suggests differential survival and reproduction of the organisms. This means the organisms that have better phenotypic advantage over the others likely to survive and reproduce in the adverse environment. Such phenotypic traits will be passed from the parents to the offspring and will promote the evolution of the species.

On the basis of the above description, the only the strongest animals will survive is the correct option.

Explanation:

Estuaries are often highly polluted bodies of water and can be used to measure the overall health of an ecosystem. Devise a logical argument for why estuaries become so polluted and provide at least 2 examples of the importance of estuaries.

Answers

The reason why estuaries have become so polluted is that humans have been piling their various wastes in them. We have introduced chemicals and many waste products that are hazardous or potentially harmful to the estuaries ecosystem.

Estuaries are very important and vital for the ecosystem. They provide two important services that ensure life. They provide water filtration and habitat protection.
