I think it's true. It might be wrong but if you want you can put false.
Answer:
Variation can be acted on by natural selection.
Explanation:
Variation are the difference that exist in the organism in terms of the body size and can be acted upon by natural selection.
Natural selection could act on the owl body size, favor the selection of owl with small body size especially when resources available are limited and can only sustain small number of individuals leading to availability of owl with small body size in such area and a gradual reduction in the number of owl with large body size.
The correct answer is chromosomal mutations
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.
