Because nutrients are the building blocks of cellular parts, a lack of nutrients can reduce the ability of cells to build new molecules that protect them from environmental stress. Dorival Martins and Ann English (2014) investigated this phenomenon with Saccharomyces cerevisiae yeast exposed to hydrogen peroxide. The researchers grew three cultures of yeast on a nutrient-rich solution and three cultures of yeast on a nutrient-poor solution. They then exposed each yeast culture to 0.2mM hydrogen peroxide and measured catalase activity (U/mg). Required:
Identify the independent variable.

work input is how much work you put into a machine and work output is the work done by the machine according to how much work you put into it. i think?

the genotypes would be 50% bb and 50% bb

the phenotypes would be 50% brown and 50% white. hope this : )

answer: mannn ion even know fam

explanation: just try asking yoo teacher yo parents or just simply another sight

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.
