How are the functions of the small intestine and the large intestine different? A: The small intestine absorbs nutrients and wastes out of the digested food, while the large intestine produces a digestive juice to break down the food. B: The small intestine breaks down food into a thin mixture containing nutrients, while the large intestine absorbs water from the food mixture and turns it into solid waste. C: The small intestine provides oxygen to the digested food before it goes to the rest of the body, while the large intestine absorbs nutrients and wastes from the food mixture. D: The small intestine pumps food and nutrients throughout the body, while the large intestine turns the digested food into a thin liquid mixture. PLS HELP
Answer:
B: The small intestine breaks down food into a thin mixture containing nutrients, while the large intestine absorbs water from the food mixture and turns it into solid waste.
Explanation:
Small intestine and large intestine are the important organs of digestive system in the human body. The small intestine functions by absorbing the nutrients of the simpler form of food. After absorbing the nutrients, the residue left is passed to the large intestine. The large intestine absorbs the water and further helps in eliminating the feces. It do not produces any enzyme to break the food unlike the small intestine. The process of digestion is completed by the small intestine.
Answer:The small intestine breaks down food into a thin mixture containing nutrients, while the large intestine absorbs water from the food mixture and turns it into solid waste. (B. I just took test got it right.)

Deer are eating Mr. Thompson’s rose bushes. He puts a new deer repellent on half of his rose bushes and then waters them. He uses the same amount of water on the other half of his rose bushes but does not put the repellent on them. What is the control group for his experiment?
Answer:
Explanation:
What he is trying to do is see if the repellant does any good. So the roses that do not get the repellent are the control group.
If they become 1/2 chewed up, and the others do not, the repellent works.
We had deer that visited our property and their favorite flower was the tulip. They are very sloppy eaters -- no table manners at all. So it was evident that they had been there, I don't think they liked coffee and that's how the problem was solved.

Just the tulips around the house.

Which of the following is lost to the environment as heat so that it cannot be continually recycled?
Group of answer choices
oxygen
nitrogen
phosphorous
energy
Answer:
Energy
Explanation:
Many chemical reactions release energy in the form of heat, light, or sound. These are exothermic reactions. Exothermic reactions may occur spontaneously and result in higher randomness or entropy (ΔS > 0) of the system. They are denoted by a negative heat flow (heat is lost to the surroundings) and decrease in enthalpy (ΔH < 0). In the lab, exothermic reactions produce heat or may even be explosive.

B. both species benefit
C. one species benefits and one is harmed
Answer:
C
Explanation:
In a parasitic relationship one species benefits while the other is harmed
Answer:
C: one species benefits and one is harmed
Explanation:
With parasitism, a symbiote takes over another body, so it would make sense for the symbiote to benefit while the other body would degrade and most likely die.

Explanation:
Sickle cell anemia illustrated in the picture below is the result of a mutation. What is the likely cause of this genetic mutation?
There's no picture.
Sickle cell anemia results from a mutation in a gene called HBB, which contains the blueprint for cells to make part of a protein called hemoglobin. The hemoglobin protein is made up of two alpha chains and two beta chains.
Sickle cell anemia is the result of a point mutation, a change in just one nucleotide in the gene for hemoglobin. This mutation causes the hemoglobin in red blood cells to distort to a sickle shape when deoxygenated. The sickle-shaped blood cells clog in the capillaries, cutting off circulation.
