Answer:

Water, carbon dioxide, and oxygen.

Explanation:

It's kind of like the lungs in your respiratory system! It takes in oxygen and submits carbon dioxide out. However, in this case, the cell membrane decides what can come in and what can't. Water, carbon dioxide, and oxygen are essential for cells which is why the cell membrane allows them to cross. This is what Paul and Jessica should show in their model.

A woman without hemophilia marries a man with hemophilia they have a daughter with hemophilia what is the genotype of the mother
Alecsey [184]

Answer:

Mother- XXH

Father- XHY

Explanation:

The mother is a carrier for hemophilia and since the disease is sex linked and found on the X chromosome, only one of the alleles has that H allele attached to it. The father is male so he only has one X chromosome, which is why he is effected by the disease and not just a carrier like the mother.

What should you do if every dilution of your sample results in a plate that is too few to count (tftc)?
lyudmila [28]

When every dilution of your sample results in a plate that is too few to count we should filter the original sample and use most probable number method .

Probable number method count and determine the number of bacteria in a culture, plate aliquots of the dilutions onto agar with sterile pipettes, spread with glass sticks, incubate at 37°C and count the number of colonies. It is imperative that you utilize your best culture technique.

Not all bacterial cells produce colonies, as some bacteria tend to clump or aggregate, and some are nonviable. For this reason results are reported as colony forming units (CFU)/ml of bacterial culture. Ideally only plates with 25-250 colonies are used.
