Answer:
The rate of diffusion, dn/dt, is the change in the number of diffusing molecules inside the cell over time. Since the net movement of diffusing molecules depends on the concentration gradient, the rate of diffusion is directly proportional to the concentration gradient (dC/dx) across the membrane.

Explanation:
Statements that explain how the human body is able to obtain energy without becoming too hot are :
B>breakdown of glucose occurs in many small steps.
C>Low-temperature breakdown of glucose is done by enzymes that catalyze specific reactions.
What is the importance of glucose?Series of reactions that remove energy from glucose by splitting it into two or three carbon molecules (pyruvates) is known as Glycolysis.
Glucose is the main energy source for cellular metabolism. Human beings derive energy from three classes of fuel molecules, namely carbohydrates, lipids, and proteins. The potential chemical energy is transformed into other forms such as thermal or kinetic.
Glucose is absorbed by stomach and small intestines absorb and then released into the bloodstream. Once they reach the bloodstream, then glucose can be used immediately for energy or stored, to be used afterwards. Human bodies require insulin to use or store glucose for energy.

Where do plants get the nitrogen they need to create amino acids and DNA?
A. Plants get their nitrogen from nitrogen gas (N2), which moves into leaves through holes called stomata.
B. Plants take up nitrates (NO3-) from the soil and convert them into ammonia (NH3).
C. Nitrogen-fixing bacteria convert nitrogen gas (N2) into ammonia (NH3), and plants take up some of the ammonia (NH3) through their roots.
D. Both B and C are correct.
E. A, B, and C are all correct.
Answer: It is D because they get it from soil and the gas
Plants get the nitrogen they need to create amino acids and DNA - option D. Option B and option C are correct.
Plants get nitrogen which is essential to form amino acid and nucleic acid that is DNA. Plants can not get the nitrogen gas directly from the air therefore, the process called nitrogen fixation takes place.
In nitrogen fixation, atmospheric nitrogen is converted to nitrates and ammonia with the help of nitrogen-fixing bacteria.Lightning and rainstorm also assist in the fixation process.plants take up nitrate from the soil and convert them into ammoniaNitrogen gas is converted into ammonia (NH3) by bacteria, and plants take up some of the ammonia (NH3) through their roots to the shoot via the xylem.Thus, the correct answer is - option D. both B and C are correct.

how are fungi organized to stay alive?
Fungi are eukaryotes and have a complex cellular organization. As eukaryotes, fungal cells contain a membrane-bound nucleus where the DNA is wrapped around histone proteins. Fungal cells also contain mitochondria and a complex system of internal membranes, including the endoplasmic reticulum and Golgi apparatus
HOPE THIS HELPED <3
Answer/Explanation:
Somewhat like animals, Fungi need oxygen and eat dead organisms in order to survive. A fungus may look like a plant, however it gets energy from living of dead plants and sometimes other fungi. Fungi need a moist area to live with plenty of oxygen making rotted out trees a perfect place to grow.
Fungi are eukaryotes and have a complex cellular organization. As the fellow answerer above said, it has mitochondria and cell membranes that are artistically arranged. Unlike plants, they do not have chloroplasts nor chlorophyll.
