Answer:

The zygote simply is the fertilized ovum or egg cell or female reproductive cell. It is the result of the process of fertilization of the fusion of the male reproductive cell (gamete) and the female reproductive cell ( gamete). In human, the zygote is the resulted cell of fertilization of the sperm and the ovum. It is diploid or 2N which means it contains two sets of chromosomes; one set from the male and the other from the female.

The gamete is the reproductive cell. There are two types of gametes; male gamete and female gamete. In human, the male gamete is called the sperm and the female gamete is called the ovum. The gamete is the last stage of the reproductive cells to be completely formed.

Fertilization is the fusion of the male gamete and the female gamete to form the zygote. Fertilization may be external as in fish or internal as in human.

roposed that the 32P label was entering PE molecules by direct exchange (swapping phosphate groups with those found in solution)
Eva8 [605]

This can be demonstrated by using an acellular environment to observe the 32P label entering phosphatidylethanolamine (PE) molecules by direct exchange.

Phosphatidylethanolamine (PE) is a major lipid component of cellular membranes in a wide range of organisms.

A scientist proposed that the 32P label was entering PE molecules by direct exchange, this can be proved using acellular environment.

In acellular environment, there aren't any bacterial cells to synthesize new PE. So if the 32P is incorporated into the PE in the acellular environment that means the proposed idea in the question stem is correct.

If no 32P is incorporated into PE in the acellular environment, then that means proposed idea is not correct.

Disclaimer: The question is not completed.

A scientist proposed that the 32P label was entering PE molecules by direct exchange (swapping phosphate groups with those found in solution) and NOT through synthesis of new PE by bacterial cells. What experimental modification can show this is NOT the case?
