What would be the advantages of using “natural regeneration” over stem cell transplants?
Serhud [2]
In the science world today, both the natural regeneration and stem cell therapy can be used to generate new cells and both processes have thier advantages and disadvantages. The following are the advantages of natural regeneration over stem cell transplants:
1. Natural regeneration is cheaper compares to stem cell transplant.
2. The process of natural regeneration is safe and does not involve the fear of unknown, long time effects like that of stem cell transplant.
3. Naturally regenerated cells can not be rejected by the patient's body but a stem cell transplanted cell can be rejected by the patient's body.

Select all of the true statements regarding non‑shivering thermogenesis.
lora16 [44]

Answer:

a, b, d y e

Explanation:

We can define thermogenesis as the method of production of lime or temperature that a living body generates, in biology it is studied that this does not occur in all animals, but is seen in so-called warm blood and some plants, there are three types of processes identified in animals:

NEAT: defined as thermogenesis that occurs without the presence of physical activity

DIT: defined as the thermogenesis that occurs with physical activity

EAT: defined as the thermogenesis that occurs with the consumption of food or diet

Thermogenesis under the thermogenin protein found in brown adipose tissue produces a disengagement of protons within the mitochondria, prevents ATP synthesis and is capable of inducing temperature with the flow of protons, it also intervenes by increasing glycolysis, lipogenesis and gluconeogenesis with which its final result in these processes is the production of energy. The effect of the sympathetic nervous system and thyroid hormones that can balance heat production without generating abnormal movements such as tremor is also recognized.

Thus we deduce that:

electron transport allows heat flow without causing tremors

Thermogenin is involved in allowing protons to enter the mitochondria and the ATP production process is carried out.

hydrolysis of fatty acids occurs in the presence of norepinephrine

in brown adipocytes ATP synthase can be avoided

The original source of all genetic variation is _____. the original source of all genetic variation is _____. sexual reproductio
IceJOKER [234]
The answer for the above question is Mutation. 
Mutations are random spontaneous changes that occur suddenly in the DNA. A single mutation can have a large effect, however in may cases evolutionary changes are based on the accumulation of many mutations. The gene flow is any movement of genes from one generation to another and is an important source of mutation

The pH of blood is not affected by: ______a. hyperventilation.b. the pKa of acetic acid or acetate. c. consuming large amounts o
julsineya [31]

Answer:

The correct option is the pKa of acetic acid or acetate.

Explanation:

The blood pH is affected by hyperventilation since it triggers hypercapnia, an increase in metabolic acids and therefore a decrease in blood pH.

Excessive consumption of sodium bicarbonate, since this would alkalize the blood, and finally, prolonged fasting or excessive hunger generates the degradation of fat sources, with the consequent formation of ketone bodies as a product, and therefore entering a metabolic acidosis.
