vova2212 [387]

Answer:

A) The two genes are unlinked and are assorting independently, leading to a 1:1:1:1 ratio of phenotypes in the offspring.

Explanation:

The χ2 value means nothing on its own--it is used to find the probability that, assuming the hypothesis is true, the observed data set could have resulted from random fluctuations. A low probability suggests the observed data is not consistent with the hypothesis, and thus the hypothesis should be rejected. The hypothesis that you are testing are two genes are unlinked and are assorting independently, leading to a 1:1:1:1 ratio of phenotypes in the offspring.

Griffith, in his 1928 experiments, demonstrated that bacterial strains could be genetically transformed. The evidence that DNA w
Nadusha1986 [10]

Griffith's experiment worked with two types of pneumococcal bacteria (a rough type and a smooth type) and identified that a "transforming principle"  could transform them from one type to another.

At first, bacteriologists suspected the transforming factor was a protein. The "transforming principle" could be precipitated with alcohol, which showed that it was not a carbohydrate. But Avery and McCarty observed that proteases (enzymes that degrade proteins) did not destroy the transforming principle. Neither did lipases (enzymes that digest lipids). Later they found that the transforming substance was made of nucleic acids but ribonuclease (which digests RNA) did not inactivate the substance. By this method, they were able to obtain small amounts of highly purified transforming principle, which they could then analyze through other tests to determine its identity, which corresponded to DNA.

What is the magnitude (amplitude) of an action potential? <br> a. 30 mv <br> b. 70 mv <br> c. 100 mv
Stella [2.4K]
Option C 100mv because the membrane goes from -70 mV to +30 mV. Thus, during the action potential, the inside of the cell becomes more positive than the outside of the cell.

AlladinOne [14]
The independent variable is the temperature. Independent variable refers to the  variable in an experiment that can be changed by the scientists or the one making the experiment. A good experiments has a single independent variable and the changes observed will be the dependent variable. In this case, the dependent variable is the gender of the turtle.
