PLEASE HELP. I REALLY NEED THIS!!!!
Viefleur [7K]

Answer:

In nature, populations are usually evolving. The grass in an open meadow, the wolves in a forest, and even the bacteria in a person's body are all natural populations. And all of these populations are likely to be evolving for at least some of their genes. Evolution is happening right here, right now!

To be clear, that doesn't mean these populations are marching towards some final state of perfection. All evolution means is that a population is changing in its genetic makeup over generations. And the changes may be subtle—for instance, in a wolf population, there might be a shift in the frequency of a gene variant for black rather than gray fur. Sometimes, this type of change is due to natural selection. Other times, it comes from migration of new organisms into the population, or from random events—the evolutionary "luck of the draw."

I hope this helps a little bit.

Biotic factors in the environment include ???
Anon25 [30]
Biotic factors are anything in a ecosystem that is living, was living, or is going to live.

From this we can conclude that the biotic factors are remains of dead organisms and flora and fauna.
Temperature and minerals in the soil are abiotic, meaning they will never live.

Explain how is it possible that when you look at the nice guy he may be looking at stars for millions of years ago
USPshnik [31]

Answer:

The reason is because it takes a long time for the light from the stars in the sky to reach earth, so the light the star was producing millions of years ago has just now reached Earth.

Hope this helped! :)
