Answer:
Gas exchange occurs at two sites in the body: in the lungs, where oxygen is picked up and carbon dioxide is released at the respiratory membrane, and at the tissues, where oxygen is released and carbon dioxide is picked up.
Explanation:
Water plants in the solution are placed under a bright lamp. Thus, option "B" is correct.
<h3>Explain your answer briefly?</h3>
As we know adding carbon dioxide in as solution result in the change of its acidity this is result in the indicator to change from blue to yellow. In the question, it is asked that what factors from the given option will cause yellow indictor to blue which means what factors cause the solution to be alkaline from acidic.
Placing the green water plants in the solution under a bright lamp will cause the is utilizing and remove present carbon dioxide in the solution and leads the to blue color from the yellow color of the solution.
Thus, this could be the answer.
The question is incomplete, however, the missing part is given as below:
A. Yeast cells and sugar are placed in the solution. B. Water plants in the solution are placed under a bright lamp. C. Algae are placed in the solution and left in a dark room. D. A person blows air into the solution through a straw.

Answer: Orbit
Explanation: The Earth’s axis being in orbit means that the Earth is in different positions around the sun at different points in time, causing day and night.
Answer:
According to Hardy Weinberg law (p+q)2=1 where p is fequency of one allele and q is the frequency of another allele.
According the question
q represent the short legs and 33 of 100 organism have short legs.
As a result the frequency of q with respect to the 100 organism is 33/100
=0.33
Therefore q=0.33
we all know that
(p+q)2=1
∴ p+q= 1
∴ p=1-q
p= 1-0.33
p=0.67
The frequency of p is 0.67

Answer:
Although the drop-down boxes are not shown, I will answer the question as follows:
The etymology of the word pericardium comes from the Greek perikardion; Greek prefix "peri" meaning "around" and the suffix "cardio" meaning "heart"
With this information you can solve the question.
Explanation:
The pericardium is a double layer where the heart is lodged. It has two membranes: the fibrous pericardium and the serous pericardium. The fibrous pericardium is formed by connective tissue. Its function is to protect the heart from the outside, it also allows you to join it with the heart cavity. While the serous pericardium is a bag where the myocardium is lodged. It consists of two layers: the visceral layer, joins the heart muscle, and the parietal layer, attached to the serous pericardium.
