Answer: C) N: Electrical energy and M: Kinetic energy
Explanation:
The first growth phase (G1): During the G1 stage, the cell doubles in size and doubles the number of organelles.
The synthesis phase (S): The DNA is replicated during this phase. In other words, an identical copy of all the cell’s DNA is made. This ensures that each new cell has a set of genetic material identical to that of the parental cell. This process is called DNA replication.
The second growth phase (G2): Proteins are synthesized that will help the cell divide. At the end of interphase, the cell is ready to enter mitosis.
Answer:
The error in tapping is ±0.02828 ft.
Explanation:
Given that,
Distance = 200 ft
Standard deviation = ±0.04 ft
Length = 100 ft
We need to calculate the number of observation
Using formula of number of observation
Put the value into the formula
We need to calculate the error in tapping
Using formula of error
Put the value into the formula
Hence, The error in tapping is ±0.02828 ft.
Answer:
B. Earth's internal heat is thermal energy generated from molten rock under great pressure.
ANSWER
B - Air density is lower, so there is less heat transfer
EXPLANATION
We want to identify why temperature decreases with higher altitude.
When radiation is absorbed by the earth's surface, it heats the surroundings and the air through convection and conduction.
However, as we ascend higher into the atmosphere, the amount of solar radiation absorbed by the troposphere's gases decreases significantly.
Due to less heat transfer, air molecules start to move away from each other causing a decrease in air density
Hence, we see that temperature decreases with increasing altitude because there is less heat transfer due to the lower air density.
The answer is option B.
