The Golgi apparatus has a polarity or sidedness to its structure and function. Which of the following statements correctly describes this polarity?A) Transport vesicles fuse with one side of the Golgi and leave from the opposite side. B) Proteins in the membrane of the Golgi may be sorted and modified as they move fromone side of the Golgi to the other. C) Lipids in the membrane of the Golgi may be sorted and modified as they move fromone side of the Golgi to the other. D) Soluble proteins in the cisternae (interior) of the Golgi may be sorted and modified asthey move from one side of the Golgi to the other. E) All of the above correctly describe polar characteristics of the Golgi function.

The correct answer is E)  All of the above correctly describe polar characteristics of the Golgi function.

Explanation:

Golgi apparatus is a single membrane-bound organelle that is made up of 5-8 flattened sacs known as cisternae. It is divided into two-phase cis face which is the entry phase and trans face which is maturing face.

Proteins and lipids produced in RER(rough endoplasmic reticulum) and SER(smooth endoplasmic reticulum) enters through the cis face and mature in trans face and exits through trans face.

Therefore protein, soluble proteins, lipids in the membrane of the Golgi may be sorted and modified as they move from one side of the Golgi to the other.

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.

not necessarily. higher fitness requires the organism to be reproductive successful. for example, an organism at age 10 with 15 offspring is much more fit than an organism at age 15 with only 5 offspring.
