The biomass b(t) of a fishery is the total mass of the members of the fish population at time t. it is the product of the number of individuals n(t) in the population and the average mass m(t) of a fish at time t. in the case of guppies, breeding occurs continually. suppose that at time t = 4 weeks the population is 821 guppies and is growing at a rate of 50 guppies per week, while the average mass is 1.2 g and is increasing at a rate of 0.14 g/week. at what rate is the biomass increasing when t = 4?

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.
