Explanation:
As tectonic plates drift due to the convection currents of the mantle below, so does the climate on the tectonic plates. This is because the drift causes the continents to glide across latitudes. Different latitudes have different climatic conditions associated with them. An example is an equatorial climate in the equator, the subtropical climate in the mid-latitudes and polar climate in the polar region.
Therefore, even though this drift is happening very slowly over millions of years, the plant and animal species in these continental also slowly adapt to the changing climatic condition in their environment associated with these continental drifts.
Answer:
Binding of <u>ACh (acetylcholine) </u> to receptors (ligand-gated) on the sarcolemma at the neuromuscular junction is vital for depolarization of the muscle fiber.
Explanation:
It allows acetylcholine to be released into this synapse when an action potential hits a neuromuscular junction. Acetylcholine attaches to the nicotinic receptors localized on the post-synaptic membrane of the muscle fibre's motor end plate, a specialized region.
Hence , the answer is <u>ACh (acetylcholine) .</u>

If reproduction didn't exist, all species would eventually go extinct.

These three
traits definitely standout as a challenge for every living creature in the ecosystem.
In Darwin’s Natural Selection Survival of the fittest: being fit is one
category in order to survive the wild, in other words, being flexible. Reproduction
is battle royale in both humans and animals, even for plants too. Why? Because
the ecosystem changes, the weather changes, the food chain is a combat to chase.
Some can’t even reproduce due to hereditary or physical causes. Energy is as
important as living. If plants can make their own food how about the carnivores
and the omnivores. Food is a challenge. Structure is sustaining the capacity
and ability to hunt and survive. Important and a by-product of obtaining
energy.
