Answer:
Explanation:
Warm fronts bring stormy weather as the warm air mass at the surface rises above the cool air mass, making clouds and storms.As the front passes over an area, the clouds become lower, and rain is likely. There can be thunderstorms around the warm front if the air is unstable.
Answer:
I think option B is right answer
Answer:
<u>3. exothermic, because the products are at a lower energy state in the reactants</u>
Explanation:
It is also because the average enthalpy is negative.
![{ \boxed{ \triangle H = \triangle products - \triangle reactants}}](https://tex.z-dn.net/?f=%7B%20%5Cboxed%7B%20%5Ctriangle%20H%20%3D%20%5Ctriangle%20products%20-%20%5Ctriangle%20reactants%7D%7D)
since products are at lower energy state, the ∆H will be negative. But the negative represents loss of heat hence exothermic reaction.
Answer: A T G G T A T A A
Reason: Adenine pairs with thymine and guanine pairs with cytosine. Just do the opposite paired letter of the DNA strand
