Answer:

total blood volume

Explanation:

Resistance to blood flow or vascular resistance refers to the slow down of the blood flow due to friction between the flowing blood and the walls of the blood vessels.

The resistance to blood flow is regulated by the viscosity of blood, total length, and diameter of the blood vessels. Higher blood viscosity imparts more resistance to the blood flow. The reduced diameter of blood vessels also restricts the blood flow through the blood vessels. Similarly, the resistance to the blood flow is directly proportional to the total length of the blood vessels.

However, total blood volume present in the body of the organisms does not affect vascular resistance. The total blood volume affects the blood pressure which in turn would affect the systemic vascular resistance.

soldi70 [24.7K]

Answer:

Lactose is more likely to be utilised by E. Coli than Arabinose because Lactose will yield more energy (ATP) and lactose breakdown will give glucose and galactose and these will enter into the glycolytic pathways to pyruvate for ATP generation until Arabinose which will undergo Pentose phosphate pathway and this does not produce enough energy.

What genes direct the
Valentin [98]

Answer:

a. hox genes.

Explanation:

HOX genes have the following functions:

  • HOX genes are the homeobox subset.
  • They specify the areas of the embryo's body plan along the animal head-tail axis.
  • They are encoding Hox proteins that specify the position characteristics and ensure that the right structures form at the right position in the body.
  • They regulate high-level executive genes, such as transcription factors and intracellular signaling molecules, which adhere, number, form, and growth to cells.

The vertebrates are highly preserved.

The clusters and other genes occur uninterrupted.

Evolutionary, the heterogeneous regulatory areas between the genes most previously present are larger and more preserved than those present at the other ends of the clusters.

The characteristical feature is that these are homeodomain proteins with a highly preserved area of DNA binding encoded with homeobox gens.
