Cells are the primary unit of structure in living organisms.
=============================================================
Explanation:
According to cell theory, cells are the building blocks of any living organism. This pertains to unicellular organisms (aka creatures that are one cell only) or multicellular organisms. This is why choice D is the answer.
Choice A is false because animal cells range in size. The largest animal cell is the ostrich egg that is about 5.1 inches across. In contrast, a neuron in the human body is about 100 microns across.
Choice B is false because plant cells have different shapes depending on the role they play in the plant itself.
Choice C is false. The number of cells varies even within the same species of a plant or animal. This is because the number is randomly determined and changes all the time. Old cells die and new ones are created constantly.

An air pressure gradients forms as the sun heats the air around an island. In which direction will the wind blow during the day?
A- from the island toward the ocean.
B- from the ocean toward the island
C- counterclockwise around the island
D- clockwise around the island
The wind will blow during the daytime in the direction from the ocean towards the island. This occurs due to the pressure gradient. Thus, the correct option is B.
How to determine the direction of wind?During the daytime, the island gets heated up faster than the ocean as the heat in the ocean gets dissipated over a large area due to convection currents. Also, the specific heat of water is greater in ocean than that of island. Since the island is hotter than the ocean, there is a build up of low pressure area on the island as hot air rises, creating a low pressure.
On the other hand, there's a relatively higher pressure at the ocean resulting in the development of pressure gradient. The wind blows from a higher pressure area to a lower pressure area, therefore wind blows from ocean towards the island (sea breeze).
Therefore, the correct option is B.

How could you increase the total energy of the spring-and-weight system?
Answer:
By increasing the displacement from the rest point or equilibrium position.
Explanation:
The energy of an oscillating spring is given by
E = (1/2) Ky²
Where K is the spring constant and y is the extension of the spring.
E is proportional to y²
meaning that: An increase in the extension will lead to an increase in the Energy of the system.
Also,
when y is maximum ( when you have pulled it to the farthest point possible without exceeding the elastic limit), it can be written as A (amplitude: meaning maximum displacement)
Then,
E = (1/2) KA²
Following the principle of energy conservation,
E = (1/2) KA² = (1/2)mv² + (1/2) Ky²
(Kinetic. (Potential
energy) energy)
We can further see that an increase in the mass of the body can also lead to a corresponding increase in the total energy of the system.
But extra careful, so you don't exceed the elastic limit (◠‿・)—☆
Answer:
Explanation: By increasing the displacement from the rest point or equilibrium position.
