Caenorhabditis Elegans Is a Nematode That Scientists Have Shown Grows

question 10

Multiple Choice

Caenorhabditis elegans is a nematode that scientists have shown grows from a single cell into about 1000 cells,of which the same 80 cells die during development through apoptosis.Studying this process in Caenorhabditis elegans has helped scientists identify the genes that regulate similar processes in humans.Which of the following statements is supported by this observation?

• A) Caenorhabditis elegans have all of the same genes as humans.
• B) Caenorhabditis elegans give live birth like humans.
• C) Caenorhabditis elegans infections in humans trigger apoptosis.
• D) Caenorhabditis elegans and humans have a common ancestor.
• E) Caenorhabditis elegans has the same organs that are present in humans.

One-sample T Test

A statistical test used to determine whether the mean of a single sample differs significantly from a known or hypothesized population mean.

Standard Error

A statistical measure that estimates the accuracy of a sample mean by quantifying the dispersion of sample means around the population mean.

Standard Deviation

A measure of the amount of variation or dispersion of a set of values, showing how much the values differ from the mean.
