Answer:

Purple colour arises due to the dominant alleles whereas white colour arises due to the recessive alleles.

For the purple colour to arise, even one of the dominant allele will be enough to cause the effect. On the other hand to see the recessive white trait, both the alleles of the gene should be recessive.

To ensure that only white flowers are grown, the farmers need to cross both white flowered plants to get the desired result.

What results would you expect from a biuret test of steak solution?

creativ13 [48]

Answer:

A positive result.

Explanation:

Biuret test is a test performed to check whether proteins are present in a given sample or not. If the solution changes its colour to violet then it means that the sample contains proteins. If the colour is not changed to violet, then the result would be negative and protein would not be present in the sample.

Steaks contain a rich amount of protein. Hence, when Biuret test is performed for a steak solution, the results will be positive. The steak sample would change colour to violet.

larisa86 [58]

Copied but correct answer.

Answer: C (She hasn't fastened the slide to the stage

Explanation:

In Microscopy even if the slide is not yet in focus,she will be able to see part of the slide which may appear as transparent image.Therefore this is a wrong answer.

If the microscope is not plugged it light can not come up.

If there are no specimen on the slide,the slide will still as transparent image at the focus.

No doubt Stella forgot to fasten the slide to the stage.,therefore the specimen on the slide was not in focus of the objective lens,rather she was focusing on the stage only,hence the visible white light.
