I think that the answer is 1 and III
Answer:
The formula for specific gravity, given that the reference substance is water, is the density of the object divided by the density of the water.
Sperm need temperatures between 2 to 10 degrees Centigrade lower and then the body temperature to develop. This is the reason why the testes are located in a bag of skin called the scrotal sacs<span> (or </span>scrotum<span>) that hangs below the body and where the evaporation of secretions from special glands can further reduce the temperature and adjust to the temperature it needs.

Answer: True
Explanation:
Over past decades the scientists have found evidence that indicates that the increase in the change of climate may lead to an increase in the frequency and intensity of the events. This may contribute to the events like extreme heat, rainfall and can even lead to disastrous events like hurricanes.
For other events like tornadoes, drought periods the evidences like little or no rain have been found.
The scientists have also found that the change in the global average temperature is because of human influence. Climatic attribution has been developed so that the scientists can identify and quantify that can measure the human-caused climatic changes resulting in the extreme weather.
