<u>Cell culture i</u>s the method applied by scientists to grown, cells in the laboratory setting to study the cells for particular reasons.

Explanation:

Cell culture is basically a method for survival, reproduction etc which are done under controlled conditions in the space outside the environment. This is also used for data mining.

Purpose: Cell culture is used for propagation of virus

Advantages:

  • Vaccine production by replication of virus
  • Detection of viral cell of virus
  • Convenient easy and economical method

Disadvantages

  • Maintenance of sterile aseptic conditions.  
  • Increases microbial contamination
  • Cross contamination takes place

Much of the regulation of gluconeogenesis is a result of the inhibition of ________. Much of the regulation of gluconeogenesis i
Monica [59]

Answer:

The correct answer will be option- Glycolysis.

Explanation:

Gluconeogenesis is a metabolic pathway which synthesizes glucose from non-sugar precursors. This pathway is activated in the low concentration of glucose due to less intake or completely absent to conserve energy.

This pathway is somewhat the reverse of the glycolysis when excess energy is present as a result of glycolysis, gluconeogenesis is inhibited and when no energy is present, gluconeogenesis is activated.

Thus, option- glycolysis is the correct answer.

During metamorphosis, a tadpole's tail is reduced in size by the process of ______. A. regeneration B. apoptosis C. oxidative ph
jolli1 [7]

The process of apoptosis, I believe, is when the tadpole's tail is reduced in size during metamorphosis.

In most animal phyla, metamorphosis actually takes place in conjunction with morphological, ecological, and physiological changes.

Marine invertebrates' larva behaves as a drifting tiny creature in the ocean, expanding its habitat distribution to find the best location for its survival.

When muscle cells undergo apoptosis, which is the final stage of their metamorphosis, they are split into membrane-bound muscle fragments and consumed by macrophages.

As a tadpole becomes a frog, apoptosis occurs. The cells in its tail are induced and it will be lost.

Which process does not occur in the Krebs cycle?
nikdorinn [45]

Answer:

The correct answer is b glucose is broken down into two pyruvate molecules.

Explanation:

Krebs cycle is one of the most important step of aerobic respiraion.Krebs cycle occur within mitochondrial matrix.During krebs cycle the acetyl CoA generated from pyruvate reacts with oxalo acetate in a cyclic manner to regenerate 4 carbon compound oxaloacetate.

 During krebs cycle pyruvate is broken down or oxidized to form 2 carbon compound known as acetyl CoA and carbon dioxide as byproduct.

  But the breakdown of glucose into two pyruvate molecules occur during glycolysis.
