Many cacti do not have leaves but rather have oversized stems.. what role of leaves is therefore taken on by the stems of cacti

a. they produce food by photosynthesis

b. they absorb water and nutrients from the soil

c. they transport materials throughout the plant

d. they store excess water

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.

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.

hope this : )
