Yes, you're correct, it's the first one. He should do research before he does an experiment, because someone else may already know.
THE ACTIN has the active site to which the heads of the thick filament will bind.
The muscle is made up of two major protein fibers, which are the actin and the myosin. Muscle contractions occur when myosin and actin slide over each other in a series of repetitive events. The protein actin has a thin structure and is abundant in eukaryotic cells while myosin is a thick filament.
The answer is c! I don’t really have much of an explanantion I just know haha
<h3>Your answer is D.</h3>
The insects are the same species.
<h3>Explanation:</h3>
A species is a group of similar organisms able to reproduce (to exchange genes and interbreed) only within the group. That means that organisms from different species could not exchange genes. Since mentioned insect groups are able to reproduce and produce offspring that could also breed, these groups belong to the same species. If they could not reproduce and produce offspring that could also breed, these groups would belong to the different species.
I hope I helped, and I always appreciate Brainliest!!! :)
Answer: B
Explanation:
"Furthermore, ectomycorrhizal fungi can slow down decomposition, a natural process that returns carbon from forest soils back to the atmosphere. In these ways, ectomycorrhizal fungi enhance the ability of forests to keep carbon locked up in trees and soils, and out of the atmosphere."
