Around the fall equinox and spring equinox the temperatures are more moderate because the Earth is at a position where it is neither in its closest, not furthest position from the Sun, the speed of the Earth slightly decreases as the spring equinox is nearing, so it starts to warm up, and slightly accelerates when the autumn equinox is nearing, so it starts to cool off. So to put it simple, these are the periods where the Earth is not in a position and speed where the Earth experiences extremes, but instead these are the transitional periods, so they are much more moderate than the extremes.
The right answer is non rebreather.
A non-rebreather mask (NRB) is mainly used to provide oxygen to treat hypoxia, in which arterial blood oxygen saturation is less than 90 percent.
Non-rebreather masks offer an increased level of moisture towards the nasal passage, which can become inflamed and irritated with prolonged oxygen treatment. Increased humidity also increases the patient's respiratory secretions.
By definition, a keystone predator is a predator that once it is eliminated from the food web, prey population thrives. This often leads to a decline in diversity within the food web. With this in mind, we can say that A and B are wrong. Additionally, from the information, we can say that D is the correct answer since they do play a very important role in the food web.
Answer:
C. Compaction
Explanation:
Chyme enters from the small intestine into the large intestine. In the large intestine, chyme becomes solid or semisolid as the water is absorbed from it. Absorption of excess water from chyme to convert it into the feces in the large intestine is called compaction. Feces consist of water, inorganic salts, unabsorbed digested materials, and indigestible parts of food. During compaction, enough water is absorbed and this makes large intestine one of the important organs in maintaining the body’s water balance.
C salt lowers the freezing point of water. I am not 100% sure how this works but I know you can put ice an water to cool sodas fast, or even make ice cream. And besides, the other answers don’t make sense.
