Answer:
1. circulate through the slug, engulfing bacteria
Explanation:
A sentinel cell is a cell of the immune system that is in charge of "eating" any kind of parasite in the body. In this case, it circulates through the slug and whenever it sees a bacterium, virus or foreign object, the sentinel cell engulfs it immediately.
Once the sentinel cell has eaten the bacterium, it produces several enzymes and substances that degrade the bacterium.
Altitude affects weather determines how dense the air is and how much heat energy the air can hold.
Option C is the correct one.
<h3>What is the relationship between authority and climate?</h3>
The relationship between climate and altitude is manifested through variations in atmospheric pressure and temperature. Although higher locations are closer to the sun, they tend to receive less heat, becoming colder, in addition to having a smaller thermal amplitude (temperature variation).
With this information, we can conclude that Higher elevations cause temperatures to drop because the higher up in the atmosphere you go the colder it gets due to air pressure in turn causing precipitation to freeze creating snow.

Answer:
Explanation:
Based on the astronomical definition of seasons, yes, the autumnal equinox does mark the first day of fall (in the Northern Hemisphere). However, according to the meteorological definition of seasons, which is based on temperature cycles and the Gregorian calendar, the first day of fall is September 1.
stole this from g**gle, but it explains it farily well. Autumnal equinox is the turning point
Answer:
Substances from an area of low concentration to and are of high concentration
Answer:
C. Nitrogen
Explanation:
One way to get this answer is through context clues and knowledge of basic chemistry:
<em>Ammonia, or </em><em>NH3 is a gas that only contains nitrogen and hydrogen</em><em>. Of all our answer choices, only (c.) Nitrogen is present in ammonia</em>
Another way to solve this is by considering biology,
<em>in which we know that plants rely on the </em><em>nitrogenous wastes</em><em> in soil to help with growth. </em>
