Answer:
what do they mean when they say "spheres" ???
It could be the lithosphere (land) hydrosphere (water) and the atmosphere (air)
Explanation:
if the water molecules are evaporating then there's obviously water involved (hydrosphere)if the water started to evaporate from the ground then lithosphere is involved, too. and the water is rising into the atmosphere, also.
Answer: Because some products in the market have prices depending on their weight and size, and we need to monitor that carefully to make sure it is the right amount.
Hope this helps!
Many clinicians diagnose disorders by using criteria listed in the DSM-5. The DSM-5 is the abbreviations for the diagnostic and statistical manual of mental disorders, it is the handbook used by the healthcare professionals as the guide to the diagnosis of mental disorders.

Answer: Option A
Explanation:
The effector response that increases the body is not associated with vasodilation of dermal blood vessels.
The skins's immense blood supply helps in temperature regulation of the body. The dilated blood vessels helps in heat loss and lowers the body temperature.
Unlike, them the vasoconstriction retains heat and increases the body temperature.
So, the correct answer is option A
Answer:
Smaller the size of the DNA fragment, farther it moves during electrophoresis. The sketch of the position of the fragments has been drawn in the figure below.
Explanation:
As we know DNA is a negatively charged molecule. So during electrophoresis the fragments move towards the positive electrode because opposite charges attract each other.
Different fragment move different distances according to their size during the electrophoresis. Smallest segment travels the largest distance in the gel medium while the largest one travels least distance.
In the question there are four DNA fragments with base pairs 4000, 2500, 2000 and 400 so the smallest segment with 400bp will be farthest from the starting point and the largest fragment with 4000bp will travel least distance in the gel medium. Their respective positions are shown in the figure below. The starting point is near the negative electrode.
