dedylja [7]3 years ago
5 0

Answer: (A) Natural selection tend to reduce genetic variation as there was a smaller distribution of beak depths, but it tends to select for the most fit phenotypes, as there was an increase in average beak depth after the drought.

How much energy is needed to heat enough water to make s cup of tea (250 mL), if the water is initially at 20.0 degrees Celsius
vredina [299]
To solve this question you need to know the specific heat of the object, which is water. The specific heat of water is 1 calorie/gram °C = 4.2<span>joule/gram °C. The energy needed would be:

Q= c*</span>m*ΔT
Q= 1 calorie/gram °C * 250 g * (85-25°C )
Q= 15000 calorie= 63000J

Marcia is given an incomplete chemical equation that includes the number of nitrogen atoms present in the products of the reacti
marysya [2.9K]

Answer:

She can conclude that the reaction started with three nitrogen atoms because she can be based in the law of conservation of matter which states that the amount of matter in a system is conserved: there were three atoms of nitrogen in the reactants and they produced three atoms of nitrogen.

Explanation:

In science, a law is a general statement that explains a large number of observations. One law that provides the foundation for understanding in chemistry is the law of conservation of matter: it states that in any given system that is closed to the transfer of matter (in and out), the amount of matter in the system stays constant, or in other words, the amount of matter in a system is conserved.

So, in this case, for Marcia to conclude that the reaction started with three nitrogen atoms, she can be based in the law of conservation of matter, and because the matter of that system is conserved, there were three atoms of nitrogen in the reactants and they produced three atoms of nitrogen.
