1-2 days before it needs its light for vitamin D
Answer:
Option-1 and 4
Explanation:
Fatty acids can be distinguished into two types: saturated and unsaturated fatty acids.
The saturated fatty acids are the fats that do not contain any double bond as a result of which they are tightly packed and are found in solid-state whereas unsaturated fatty acids are the acids that contain double bond in their structure and are found in liquid form.
The cold-tolerant species show an adaptation to survive in cold species by modifying their cell membrane composition that is they increase unsaturated fatty acids which help in maintaining the fluidity of the cell membrane.
Thus, in the given question option-1 and 4 show, this adaptation and are true options.
D. The daily release of hot water into the pond from a local factory.
Explanation:
The daily release of hot water into the pond from a local factory would most likely affect the health of fish in a local pond.
Fishes are cold blooded animals. They derive their temperature from the water around them. They need a fairly stable daily temperature.
If the temperature of the water varies to a large extent too much daily, they will suffer.
Hot water will affect the fish population badly. It will cause the fishes to die off and suffer from too much increase in temperature.
Other factors listed in the options will improve the fish life.
