I PUT THIS AS 20 POINTS SO PLEASE HELP! :(

Male elephant seals are five to six times heavier than females of the species. The males use their large body size to fight for control of groups of the smaller-sized females. Fights between two male elephant seals usually last only a few minutes, with one of the males backing off and the other establishing itself as the leader of a group of up to 100 females. What resource are male elephant seals competing for during these conflicts? food shelter mates water

3points hurry! what is the relationship between biotechnology, sharkskin, and disease resistance? bioengineers have developed an artificial sharkskin that does not allow resistant bacteria to grow on it. disease-causing microbes have been genetically modified to keep them from infecting the skins of sharks. scientists have created a device that can be attached to the skins of sharks that dramatically increases their abilities to resist disease. sharkskin produces many chemicals that can be collected and used to create antibiotics.
