The answer is; SET B
Polar molecules interact well with water because there are charged. Water molecules are partially charged (the oxygen end is partially negative while the hydrogen end is partially positive). Therefore polar molecules can interact stably with charged molecules. The hydrophobic end is non-polar and is ‘water-hating’. When mixed with water, the non-polar region clumps up into globules so they don’t interact with water.
Answer:
False.
Explanation:
Cell membrane is made of the lipids and proteins with the attached moieties of carbohydrates. The plasma membrane is the selectively permeable membrane that allows the diffusion of some selected particles only.
The transport along the cell membrane depends on the size and the hydrophobicity of the molecule. The size of oxygen is although higher than magnesium but to its highly hydrophobic nature it can easily pass through the plasma membrane as compared with the magnesium. The oxygen diffuses out faster than magnesium.
Thus, the answer is false.
B- Reproducing more often. If the environment is not right for them then reproduction doesn’t help them adapt. They respond by changing behavior, moving to another area, and even modifying their physical bodies (diets included).
The correct answer is option (A) leaves > deer > wolf.
A food chain is a linear sequence of organisms through which the nutrients and energy flow as one organisms feeds on the other. They show organisms starting from the producers and end with consumers or sometimes with detrivores or decomposers. Each level of the food chain is called the trophic level. The producers which use solar energy and prepare their food occupy the first trophic level, followed by the primary, secondary, tertiary, quaternary consumers occupying the next trophic level.
In the food chain given above, leaves > deer > wolf, deers feed on the leaves which are maximum in number comparitively, wolf feeds on the deer which are comparitively more in number than the wolves. This is the correct sequence of food chain showing the tranfer of energy and decreasing number of organisms with subsequent increase in the trophic levels.
