Hi, I have a biology test with 50 questions on it and I need help ASAP before the class ends tomorrow at midnight. I need help f

rom an expert on brainly or someone who is really good or has already taken the test. Should I post each question one by one or as a giant question? Is there anyone who can help? Maybe I could email the questions? I currently have 375 points that I am more than willing to give away to anyone who can help. Thank you!

Selection that acts over evolutionary time to preserve traits that increase an individual's ability to mate is known as ________
deff fn [24]

The selection that acts over evolutionary time to preserve traits that increase an individual's ability to mate is known as se_xual selection.

<h3>What is se_xual selection?</h3>

The expression 'se_xual selection' makes reference to the type of evolutionary constraint on the individual's ability to mate.

Se_xual selection is fundamental to increase the genetic variation and thus enhance adaptive chances.

Se_xual selection can be considered a special type of natural selection that acts at an individual level.

What controls the timing of The Great Migration?
Andreyy89

Answer:

The best time to see the Great Migration is during the dry season, between July and early October. It's warm, weather is stable, and animals are abundant. The sparse vegetation and dried-up waterways force the animals to head up north to find food and drink.

Know what makes a solution acidic or basic (the pH number and the ions).
Brrunno [24]

To determine whether an acidic or basic solution, it is first necessary to compare the concentrations of the hydronium (H3O +) and hydroxide (OH-) ions in the solution.

In acidic solution, the concentration of H3O + ions is higher than that of OH- ions.

  • In acidic solution, the concentration of H3O + ions is higher than that of OH- ions. Such a solution can be achieved by adding a small part of the H3O + ions, for example. Acid solutions have a pH below 7, the further away from 7 the pH of the solution is the higher its acidity content.  According to Le Chatelier's principle, when a disturbance is caused to an equilibrium system, it tends to readjust in order to diminish the effects of that force. This means that if an acid is added to water, the H3O + ions will be in excess and the equilibrium will shift in the opposite direction to the left. Then these excess ions will react with the OH- ions. Thus, the concentration of OH- ions will decrease and the solution will become acidic.
  • In basic solutions, the concentration of OH- ions is higher than that of H3O + ions.  If we add a base to the water, it means that we will be adding OH- ions and, as explained in the previous section, by Le Chatelier's principle, the equilibrium of the water selfionization reaction will shift in the opposite direction, and the excess ions will react. with the H3O + ions, decreasing their concentration and making the basic solution.  Basic solutions have a pH greater than 7, the farther from 7 and closer to 14 the pH of the solution, the higher the basification content.
