Answer:

C) Increases its boiling point

Explanation:

Adding more solute to a solvent increases its boiling point! This is a phenomenon described by the colligative properties. When we add a solvent to a solute, the boiling point increases.

Put in vapor pressure terms, a liquid boils at the temperature when its vapor pressure equals the surrounding pressure. For the solvent, the presence of the solute decreases its vapor pressure by dilution. Thus, a higher temperature is needed for the vapor pressure to reach the surrounding pressure, and the boiling point is elevated.

zysi [14]

Answer:

The correct option is <em>B) Only triazine-resistant weeds survived and reproduced, so each year more pigweed was triazine-resistant.</em>

Explanation:

With time, the pigweed became resistant to triazine. As we know, according to the theory of natural selection only those species are able to survive and reproduce which are better adapted to live in an environment and adapt to the environmental changes. As the triazine- resistant weeds were better adapted survive and reproduce in the area, it began passing its resistant genes to offsprings. As a result, the population of the pigweed increases.

Lion vs elephant digestion lab

aalyn [17]

Answer:

In lions, digestion takes place in the stomach while in elephant, digestion takes place in cecum.

Explanation:

Lion eats meat which needs a powerful digestion of strong juices which helps in the breakdown of food. There are four compartments of the stomach of lion that are rumen, reticulum, omasum, and abomasum. These chambers have microorganisms which helps in the breakdown of food materials while in the elephant, the stomach primarily functions in the storage of food and digestion takes place in the cecum that is connected to the large intestine.

Suppose an exponentially growing culture of bacteria is treated with a potential antimicrobial compound. Over the next few hours

Marta_Voda [28]

Answer:

Bacteriostatic

Explanation:

The antibiotics are the compounds which are used to treat the bacteria and are of two types: the bacteriostatic and bactericidal.

The bacteriostatic antibiotics are the antibiotics that do not kill the cells but they stop the reproduction of the bacteria and keep them in their stationary phase.

In the given question, since the antibiotic does not kill the cell but stops the doubling that is reproduction therefore the antibiotic is bacteriostatic.

Thus, bacteriostatic is correct.
