Answer:
The surface area of a sphere = 48 ²
Explanation:
Given:
The radius of a sphere = 2 meters
Use π = 3 (Approx)
Find:
The surface area of a sphere.
Computation:
⇒ The surface area of a sphere = 4πr²
⇒ The surface area of a sphere = 4(3)(2)²
⇒ The surface area of a sphere = 4(3)(4)
⇒ The surface area of a sphere = 48 meter²
Answer:
B
Explanation:
Measurement of Water in the Air
The specific humidity of air is a measure of how much water is in the air. Warmer air can hold more water than colder air. When the air reaches its capacity, it is saturated. This capacity doubles for about every 11°C rise in temperature.
Answer:
The rough endoplasmic reticulum
Explanation:
The rough endoplasmic reticulum (ER) is an organelle that has the main function of producing proteins for the cell.
Antibodies are a type of protein, so they are made by the ER.
Since the immune cell can rapidly produce antibodies, it must have a significant amount of rough ER to make the proteins.
