What is types of tissue in the kidney?

The kidneys are made of many connective tissue called renal fascia and perirenal fat (a thick layer of adipose tissue) which helps to protect it.

Renal capsule (a connective tissue)  closely envelopes each kidney and provides support for the soft tissue that is inside.

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.
