B greenhouse effect
C photosynthesis
D transpiration

Answers

B. Greenhouse effect

The condition that is caused by carbon dioxide, methane, and water vapor trapping heat in the Earth's atmosphere is known as the greenhouse effect. Thus, the correct option is B.

What is the Earth's atmosphere?

The earth's atmosphere may be defined as the significant presence of a layer of various gases that surrounds the whole planet. It is known that the Earth's atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases.

Carbon dioxide, methane, and water vapor are considered greenhouse gases that ultimately capture the heat radiations from the sun and liberate the earth's atmosphere. As a result of this, the average temperature of the earth's surface has gradually increased for four to five decades.

This is all known as the greenhouse effect. The Greenhouse effect may be defined as the phenomenon of keeping the earth warm due to the presence of certain gases in the atmosphere that captures heat from the sun.

Therefore, the condition that is caused by carbon dioxide, methane, and water vapor trapping heat in the Earth's atmosphere is known as the greenhouse effect. Thus, the correct option is B.

Answers

Answer:

Yo i dont know but when someone does please help me bro

Explanation:

In cell A, the structure labeled X is a centriole.

Centrioles are cylindrical organelles found in animal cells, usually existing in pairs called the centrosome. They play a crucial role in cell division by organizing and forming the spindle fibers during the process of mitosis and meiosis.

Centrioles are involved in the separation of chromosomes, ensuring that each daughter cell receives the correct number of chromosomes.

Additionally, centrioles are essential for the organization of microtubules in the cytoskeleton, which provides structural support and maintains cell shape.

Their function in cell division and cellular organization makes centrioles vital components of animal cells.

How does starting the y-axis at 300 affect the graph? Remember that no matter what number you start labeling an axis at, you have to go up by the same amount for each subsequent tick mark!

Answers

Not sure if this applies to biology, but I’m using more statistics for this.

Basically, when you change the y-axis to 300, you are able to exaggerate the patterns on the graph. From afar, or starting the y-axis at 0, a person cannot easily identify the increases and decreases of CO2. However, with a y-axis at 300, you see these changes much more easily, so you can make accurate inferences and conclusions regarding the graph.
