Fats, such as olive oil and sesame oil, are produced in plants and are liquid at room temperature. a) hydrogenated b) oxidized c) polysaturated d) polyunsaturated

The correct answer is option D. polyunsaturated.

The olive oil and the sesame oils are produced in the plants and they are PUFA rich. The PUFA refers to the trans fatty acids, which are Polyunsaturated Fatty acids. The plants oils are the rich source of the fatty acids. The trans fatty acids are considered as the healthy fatty acids and they are not so bad for regular consumption purpose.

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.

explanation:

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
