The Major function of the respiratory system is to exchange oxygen and carbon dioxide. Inhaled oxygen enters the lungs and reaches the alveoli, the layers of the cells lining the alveoli and the surrounding capillaries are each only one cell thick and are in very close contact with each other, the barrier between air and blood averages about 1 micron in thickness. Oxygen diffuses quickly through the air-blood barrier into the blood in the capillaries. Similarly, carbon dioxide passes from the blood into the alveoli and is then exhaled.

Answer:

False

Explanation:

Sex is a biological term and gender is depended on the roles performed by an individual. In our society it is mandatory for a man or woman to behave and develop sexual preference for its opposite gender and this conservative thought process had strongly held the base of defining a sexual acts which is intended to happen between a male and female only.

However, this is not something defined by nature but by individual likeliness. This is the reason why even after being a male by sex, a male by gender can have likeliness for another male. This is something which cannot be bounded by social and cultural belief even after being into it for years.

Hence, the given statement is false

Hello!

your answer is A.  How much energy is used to make one paper bag?

the word "should" is a giveaway of B, C, and D being questions for personal opinions. everyone has different views on what SHOULD be, so if you asked 100 people, chances are you'd get many different answers.

A can only have one possible answer.

(I don't know the answer to how much energy is used to make one paper bag so let's just leave it at that, shall we?)

I hope this helps, and have a nice day!
