Once energy from the Sun gets to Earth, several things can happen to it: Energy can be scattered or absorbed by aerosols in the atmosphere. ... Light colored surfaces are more likely to reflect sunlight, while dark surfaces typically absorb the energy, warming the planet.
You should mix
4µl of DNA sample and complete it with
96µl (100-4) of water.
You can figure this out by using
C1.V1 = C2.V2C1 = 250 <span>ng/μl (Sample Concentration)
</span>V1 = ?
(the necessary volume to take from the DNA sample)C2 = 10 <span>ng/μl (PCR concentration)
</span>V2 = 100 µl (total volume)
V1 =

=

=
4µl
For the water: 100µl (total volume) = 4µl + Water
Water volume = 96µl
The normal force is greater than the force of gravity
Answer: 1. True
2. Between six and right hours
Explanation:
1. Energy simply refers to the ability to do work. It's the strength that's required to be able to sustain a mental or physical activity.
It should be noted that fir positive interaction, energy requires physical activity, a balanced diet, adequate sleep, satisfying work and opportunities. Therefore, the statement is true.
2. Even though the hours of sleep that's used by people typically varies, adults generally need about six to eight hours of sleep.
