pickupchik [31]

Answer:

1)required for cellular respiration(Oxygen only)

2) net diffusion from alveoli to lung capillaries(Oxygen only)

3)sometimes transported as bicarbonate(Carbon Dioxide Only)

4)net diffusion from body tissues to blood(Carbon Dioxide Only)

5)net diffusion from lung capillaries to alveoli(Carbon Dioxide Only)

6)waste product of cellular respiration(Carbon Dioxide Only)

7)enters alveoli during inhalation(Both Oxygen and carbon dioxide)

8)transported by hemoglobin(Both Oxygen and carbon dioxide)

Explanation:

Gas exchange is a mechanism that helps the body to get the necessary Oxygen that is required for cellular respiration to take place

There is diffusion of oxygen to capillaries that are present in the lungs from the alveoli.

Gas exchange is a mechanism that is also responsible for the body to get rid of waste such as carbon dioxide,

Which of the following methods involves counting the number of organisms in a specific area?
lara [203]
The answer is C. The method which involves counting the number of organism in a specific area is sampling. It is one common method to estimate the population of certain organisms used by biologists. In a given range, the number of plot is determined and per plot the number of individuals is multiplied to the number of plots then this results to an approximate population size.

Two steel balls that are the same mass and size are rolled with the same force across different level surfaces.
san4es73 [151]

Answer:

The reason why the ball rolling across carpet will come to a stop faster than the one rolling across concrete is the friction (option B).

Explanation:

The contact surface on which the balls move is different. Irregularities in the carpet cause the ball in it to stop faster. The concrete surface is less irregular, and allows the ball to move a little more and then stop. This is due to friction.

In physics,<u> friction is a force that is capable of opposing movement</u>, since the contact of two surfaces limits its movement. A smooth surface produces less friction than a rough or irregular surface.

Since the friction that stops both balls occurs when they are in motion, it is called dynamic friction, that is, the force that causes a moving body to stop.

Anestetic [448]

Answer:

If "New Hair" work better than "Rogaine", more men in Group C would grow hair over their head than the amount of men in Group B would.

Explanation:

Since Dr. Rodriguez thinks her drug, the "New Hair" would work better than "rogaine", the result of the experiment should be "more men in Group C would grow hair over their head than the amount of men in Group B would". Therefor the whole hypothesis would be: If "New Hair" work better than "Rogaine", more men in Group C would grow hair over their head than the amount of men in Group B would.

Hope it helps, drop a comment if you still have a question.
