Answer:
B. 100% white
Explanation:
Since white is recessive each plant with white flowers will have the genotype ww. This is because it take two recessive genes to get a white flower. This also proves that the only possibility for offspring of the white flowers is white.
The period T of a pendulum is given by:
where L is the length of the pendulum while
is the gravitational acceleration.
In the pendulum of the problem, one complete vibration takes exactly 0.200 s, this means its period is
. Using this data, we can solve the previous formula to find L:
Answer:
d. W<0 and Q<0
Explanation:
Heat (Q) and work (W) are ways of exchange of energy.
When a system gains heat, that its temperature increases, and, because the heat flows to the system it's positive (Q>0), and when it loses heat the inverse happens and Q<0.
When the system expands, it does work at the surroundings, so the work is going from the system, and it's positive (W >0), when the inverse happens, the work goes to the system and W<0.
So, the gas is compressed, then W<0, and it warms up. To cold it, the tank has put a tub with water, do the gas will lose heat and Q<0.

The answer would be: <span>b. interactions between the atmosphere and geosphere during a drought
The experiment is clearly demonstrating what happens in drought. The soil that is put into direct sunlight without getting any water. The heat from the sunlight will be absorbed by the soil, makes the water content of the soil evaporates into the air. Since you don't give any water, the soil will be dry and start to crack.
The soil should represent the geosphere. The air represents the atmosphere.
