B.
prokaryotic because prokaryotic cells lack a nucleus and membrane-bound structures.
This is could be both negative and positive but in this case I believe it’s referring to the reclamation of the environment in order to grow our agricultural
A 60.0 kg secretary running up a 4.0 m tall flight of stairs in 4.2 s has an average power of 560 W (Option b).
<h3>What is power?</h3>
Power is the work done over a period of time.
A secretary with a mass (m) of 60.0 kg runs up a 4.0 m (d) tall flight of stairs. Given gravity (g) is 9.81 m/s², the work (W) done is:
W = m × g × d = 60.0 kg × 9.81 m/s² × 4.0 m = 2.35 × 10³ J
They do 2.4 × 10³ J of work in 4.2 s (t). The average power (P) is:
P = W / t = 2.35 × 10³ J / 4.2 s = 560 W

Had to look for the options and here is my answer.
Given the situation that a poison is consumed and this prevented the acetylcholine release, the one that would most likely occur at a myoneural junction is that "sodium and potassium gates on the motor end plate will not open". Hope this helps.
Answer:
No, not at all. This kinetic energy of car is converted/lost in the form of sound and heat under the tyre when driver apply brakes.
Explanation:
This law states that energy can neither be created nor destroyed but it changes from one form to the other.
In this case reduction of kinetic energy of car does not contradict the law but it changes into heat and sound energy. When driver apply brakes we hear the sound of Tyre due to friction with the road. The tyre become hot too.
So it is not in contradiction to the law of conservation of energy (First Law of Thermodynamics).
Please mark branliest if you are satisfied with the answer. Thanking you in anticipation.
