Answer:
Acar starts moving at 85 m/s for 10 seconds. Then the car decelerates for 5 seconds to 30 m/s. After 10 more seconds, the car is traveling 120 m/s and continues at this speed for 10 additional seconds. What is the acceleration of the car between seconds 10 and 15?
Explanation:
so that's it
Answer:
Biological membranes have three primary functions: (1) they keep toxic substances out of the cell; (2) they contain receptors and channels that allow specific molecules, such as ions, nutrients, wastes, and metabolic products, that mediate cellular and extracellular activities to pass between organelles and between the cell and the outside environment; and (3) they separate vital but incompatible metabolic processes conducted within organelles.
Answer:
Water that falls to Earth from the atmosphere.
Explanation:
Precipitation is any form of liquid or solid water particles that fall from the atmosphere and reach the surface of the earth.
Answer:
Precipitation is water that goes through a process that prosses is water evaporates and the turns into clouds then when there is enough water in the clouds it rains and starts over again.
Explanation:
B/The second choice
Answer:
The correct answer is option C.
Explanation:
The human gastrointestinal microbiota or the gut microbiota or the gut flora refers to the microbes, which thrive in the digestive tracts of humans. The human gastrointestinal tract comprises the gathering of all the genomes of gut microbiota. It is the niche where the human microbiota is found.
The microbial composition of the gut microbiota differs across the digestive tract. In the small intestine and stomach, very small species of bacteria are found, while the colon comprises the densely populated microbial ecosystem. Of these over 99 percent of the bacteria found in the gut are anaerobes, as the space within the intestines is highly anaerobic.
These microbes are confined deep within the body where oxygen cannot reach as it is not supplied with the help of blood vessels. Thus, a highly anaerobic environment is witnessed deep within the intestinal regions.

Proteins have multiple functions in living organisms, including enzymatic activity, transport, and structural support.
Proteins have several important functions in living organisms. They can serve as enzymes, which are molecules that speed up chemical reactions. Proteins can also act as transporters, helping to move molecules and ions across cell membranes. Additionally, proteins are essential for structural support in cells and tissues.
For example, hemoglobin is a protein that transports oxygen in the blood. It binds to oxygen molecules in the lungs and releases them to cells throughout the body. Another example is the sodium-potassium pump, which is a protein that helps maintain the balance of ions inside and outside of cells. This pump is crucial for nerve cell communication and muscle contraction.
