Total peripheral resistance ________.

Biology
1 answer:
Gennadij [26K]3 years ago
5 0

Answer:

C). viscosity increases with increasing length of the blood

Explanation:

Systemic vascular resistance (SVR) refers to the resistance to blood flow offered by all of the systemic vasculature, excluding the pulmonary vasculature. This is sometimes referred as total peripheral resistance (TPR).

Some factors that decrease blood flow and increase resistance include increased viscosity of the blood, increased length of the blood vessel and decreased radius of the blood vessel. Blood vessels - and in particular, the more muscular arteries - are often the source of resistance.

What determines resistance are:

1. Resistance is proportional to LENGTH (L) of the tube (blood vessel)

-Resistance INCREASES as length increases

2. Resistance is proportional to VISCOSITY, or thickness, of the fluid (blood)

-Resistance INCREASES as viscosity increases

3. Resistance is inversely proportional to tube RADIUS to the fourth power

4. Resistance DECREASES as radius increases

Sam is studying the interaction between porcupines, pinion pine trees, and pine bark beetles. Over the course of his study in Colorado, he observes the behaviors of 25 porcupines, records the location of 151 pinion pines, and traps 332 beetles.

His study include 3 populations

  • Population ecology is the study of the factors influencing the number and distribution of animal and plant populations. 
  • The study of the development, control, and interactions of animal populations is known as animal population ecology.
  • A population's growth may be significantly influenced by the behavior of its constituent individuals, and the presence of predators, prey, and competitors in the community will also have significant effects.
  • The population is a level of organization that lies between individuals and communities, but there is no clear distinction between the phenomena that affect these levels and those of the population.
  • Here Sam studies 25 porcupines, records the location of 151 pinion pines, and traps 332 beetles. hence 3 populations are being studied here.

sp2606 [1]

Answer:

The correct answer is -

1. c. both

2. b. gluconeogenesis

3. d. neither

4. b. gluconeogenesis

5. a. glycolysis

6. c. both

7. a. glycolysis

8. d. neither

Explanation:

Gluconeogenesis is the formation or synthesis of glucose while glycolysis is the conversion of glucose into pyruvate. Gluconeogenesis requires an enzyme for a non-reversal reaction which is not required in glycolysis.

Glyceraldehyde 3-phosphate dehydrogenase is an enzyme present in glycolysis that converts glyceraldehyde 3-phosphate to 1,3-bisphosphoglycerate. It is a reversible reaction, this enzyme also present during gluconeogenesis converts 1,3-bisphosphoglycerate to glyceraldehyde 3-phosphate.

Glucose 6-phosphate to glucose during gluconeogenesis by glucose-6-phosphatase. Alcohol dehydrogenase is used for the conversion of ethanol into acetaldehyde and neither present in glyconeogenesis nor glycolysis. Oxaloacetate converts to phosphoenol pyruvate during gluconeogenesis by Phosphoenol pyruvate carboxykinase.

Fructose 6-phosphate changes into fructose 1,6-bisphosphate by Phosphofructokinase-1 during glycolysis.

Phosphoglycerate mutase is present in both pathways during glycolysis and during gluconeogenesis. This enzyme converts 3-phosphoglycerate to 2-phosphoglycerate and also converts 2-phosphoglycerate to 3-phosphoglycerate in glycolysis and gluconeogenesis respectively.

Hexokinase converts glucose to glucose 6-phosphate during glycolysis. However, Pyruvate dehydrogenase neither present in glycolysis nor gluconeogenesis.
