Answer:
Explanation:
Yes. Animals and humans have instincts. Every creature does. Most of the time offspring are born in populations that are thriving so their young and their genes can be passed on.
Gases are less dense than solids. this is because, since density refers to how close the particles are together, in gases, there is more space for the particles to move, making it less dense than solids.
The best answer would be B
Answer:
The best answers to the question: Which of the statements are true? Would be the following:
1. Fats that contain more saturated fatty acid residues than unsaturated fatty acid residues are more likely to be solid at room temperature.
3. Unsaturated fats are more likely than saturated fats to be liquid at room temperature.
5. Triacylglycerols (tryglicerides) are composed of fatty acid residues and glycerol.
Explanation:
The options chosen from the five options are all characteristics of triglycerides. These molecules, which are pretty complex, have all of the options above except for 2 and 4 because these molecules, especially unsaturated fats do not have a high melting point, that is why they remain liquid at room temperature. So that option is wrong. Also, although tryglicerides do have carboxyl groups, chemically speaking they are better categorized as esters.
