D because gravitational force cannot pull or push
Answer:
Force = 15.4N
Explanation:
Force=Mass x Acceleration
Force = 20Kg x Acceleration
20Kg x 0.77m/s = 15.4N
<em>Answer is entirely dependent on what the acceleration is.</em>
Answer:
b
Explanation:
its b because it doesnt say any else then 15 or any clues so its tryna trick u
Biological systems do not contradict the second law of thermodynamics. Even in this case, entropy is still always increasing. Biological systems can only decrease their own entropy by using copious amounts of energy and by increasing entropy in their surrounding environment. Also, unfavorable anabolism reactions are always paired with more favorable reactions, such as the use of ATP in order to make the overall Gibb's free energy of the reaction negative.
Answer:
A) The gene flow between hatchery-reared and wild populations is leading to a decline in fitness of wild populations.
Explanation:
<u>we have relative fitness at its greatest in trouts whose parents are wild x wild. crossing the wild with hatchery reared causes a decrease in the fitness of the troutgene flow is the exchange of genes between two different breeds. the wild is a greatly diverse breed and it is highly adaptive. while the hatchery reared is less adaptive.when these two breed less fit alleles will then be transferred to the wild</u>
therefore option a answers the question
