Answer:
Natural selection
Explanation:
Adaptation deals with organisms becoming more suited for their environment. It does not directly determine survival and reproduction.
Artificial selection is caused by humans. Therefore, adaptability may not play a role in this selection.
Natural selection is caused directly through adaptability. It results in organisms reproducing if they are capable of survival. Organisms that cannot adapt do not survive.
Answer: B
Explanation: sorry if I'm too late but i just did this question and that was the right answer
The answer for the following problem is mentioned below.
Explanation:
Given:
mass of iron (m) = 15.75 grams
heat (q) = 1097 J
initial temperature () = 25°C
final temperature () = 177°C
To find:
specific heat (c)
We know;
c = q ÷ mΔT
where;
c represents the specific heat
q represents the heat
m represents the mass
t represents the temperature
c =
c = 0.45 J/kg°C
<u><em>Therefore the specific heat capacity of iron is 0.45 J/kg°C.</em></u>
