Describe the components in the blood that affect viscosity. Your answer: The viscosity of blood is due to the presence of plasma proteins, white blood cells, red blood cells, and platelets. These elements and plasma proteins create resistance as they slide past one another, increasing resistance to flow.The usual pressure difference between the left and right ventricles is about 100 mmHg. The normal cardiac output (the blood flow in the above equation) is about 5 liters/minute. The total peripheral resistance is about 20 (mmHg*min/liters).Prolonged aerobic exercise training may also increase stroke volume, which frequently results in a lower (resting) heart rate. Reduced heart rate prolongs ventricular diastole (filling), increasing end-diastolic volume, and ultimately allowing more blood to be ejected.

Use the probability method to calculate the genotypes and genotypic proportions of a cross between AABBCc and Aabbcc parents.

lora16 [44]

For this, you need to use Punnett squares.

You know the genotype of the parents, and for the cross, you need to separate into two alleles, both genes.

AABBCc divided like ABC and ABc.

Aabbcc divided like Abc and abc.

Now you can cross them, and all probabilities will be:

AABbCc, AaBbCc, AABbcc and AaBbcc

So, you could say 25% of the offspring will be AaBbCc, 25% AaBbcc, 25% AABbCc, and 25% AABbcc

In which situation would new technology be most likely to cause a change in an existing theory about a cell?

ELEN [110]

The situation that a new technology would be most likely to cause change in existing theory about cell is : D. The technology allows detection of a substance that could not be detected previously

Cell is incredibly small and we still hasn't 100% figured out their perfect mechanism yet. New technology might found the new substance that alter the cell's theory as a whole
