what will most likely happen in the absence of a vacuole photosynthesis will not take place genetic information will not be transmitted by the cell energy will not be released during cellular respiration the cell will not store food water nutrients and waste

Answers

Answer:

D) The cell will not store food water nutrients and waste

Photosynthesis in plants takes place to synthesis food and energy. In the absence of this process, plants cannot store food and nutrients .

What is photosynthesis ?

Photosynthesis is a biochemical process takes place in plants to synthesis chemical energy in the form of glucose by the aid of light energy. The green pigment in leaves called chlorophyll helps to absorb sufficient light energy for this process.

In a photosynthetic reaction, water and carbon dioxide combines to form oxygen gas and glucose. This glucose is the source of energy in plants. The oxygen gas released by photosynthesis is used by animals for respiration.

If photosynthesis does not  taking place, plants fails to synthesis their food which further affect the cellular respiration as well. Therefore, option d is correct.

While at the beach, Sam and Sal recorded the temperatures on land and at sea. They discovered that at night the ocean air temperature was higher than the temperature over land. During the night, which direction will the wind MOST LIKELY blow?

Answers

If the air over the ocean is warmer than the air over the land,
the air over the ocean will rise, and the air from the land will
slip in under it. 

The wind will blow FROM the land out TO the ocean.

Answer: From land towards sea

Explanation:

Land breeze occurs at night in coastal regions. At night, the land cools down faster a compared to water in the sea. Thus, the air above the sea is less dense and thus, has low air pressure as compared to air over land. Thus, the wind would blow from land towards sea during night. This is known as land breeze.

A wheel rotates clockwise 10 times per second. what is its angular speed answer

Answers

Final answer:

The angular speed of a wheel that rotates clockwise 10 times per second is 20π rad/s. The direction of this rotational movement is determined by the right-hand rule used in physics and engineering. It is important to note that if the angular velocity is not constant, then the system has an angular acceleration.

Explanation:

The question is asking about the angular speed of a wheel that rotates clockwise 10 times per second. In physics, angular speed is defined as the measure of how quickly an object moves through an angle. It is calculated by dividing the number of rotations or revolutions by the time period. In this case, the wheel rotates 10 times per second, which is the same as making 10 complete revolutions each second. We know that one complete revolution (360 degrees) is equivalent to 2π radians, so the angular speed in radians per second would be 10 * 2π, which is equal to 20π rad/s.

The concept of angular speed is often used in physics and engineering to describe the motion of objects rotating around an axis. The direction of angular velocity is determined by the right-hand rule. The right-hand rule is such that if the fingers of your right hand wrap counterclockwise from the x-axis (the direction in which increases) toward the y-axis, your thumb points in the direction of the positive z-axis (Figure 10.5). An angular velocity that points along the positive z-axis therefore corresponds to a counterclockwise rotation, whereas an angular velocity that points along the negative z-axis corresponds to a clockwise rotation. If the system's angular velocity is not constant, then the system has an angular acceleration.
