<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

A cell with a diploid number of 24 undergoes MITOSIS, how many chromosomes are in each daughter cell?
GalinKa [24]

Answer:12.

Containing two complete sets of chromosomes, one from each parent.

Explanation:   Once mitosis is complete, the cell has two groups of 46 chromosomes, each enclosed with their own nuclear membrane. The cell then splits in two by a process called cytokinesis, creating two clones of the original cell, each with 46 monovalent chromosomes.

Why might using retroviral vectors for gene therapy increase the patient's risk of developing cancer? a. Retroviral vectors may
Svetllana [295]

The use of retroviral therapies can increase the patient's risk of developing cancer because they may integrate recombinant DNA into the genome in ways that may misregulate the expression of genes. Therefore the correct option is D.

<h3>What is retroviral therapy? </h3>

Retroviral therapy is an HIV treatment where medicines are taken as prescribed by a healthcare professional. This treatment reduces the amount of HIV in an HIV-infected person.

HIV does not have a cure but antiretroviral therapy can reduce the risk of potential health issues caused by HIV.

This treatment can help to control the virus in an HIV-infected person within 6 months. The treatment for HIV cannot prevent the transmission of other sexually transmitted diseases.

Therefore the correct option is D.

During the absorptive state, metabolism adjusts to either provide energy for immediate use or store excess energy to be used lat
Effectus [21]

Answer:

A. Catabolic

B.Anabolic.

C. Anabolic

D. Catabolic.

E.Anabolic

F. Catabolic

G. Anabolic

H. Catabolic

Explanation:

Catabolic process is a metabolic processes that breakdown complex or larger molecules into smaller sizes by releasing energy.

The examples of such metabolic processes are;

Glucose is used as the primary fuel for energy

Dietary carbohydrate from a meal is digested and absorbed as monosaccharides, mainly glucose

Dietary protein from a meal is digested and absorbed as single amino acids.

Fatty acids are used as fuel sources for some tissues.

All this processes are catabolic processes because large molecules are broken to smaller ones and all this processes release energy.

Anabolic process is a metabolic process where smaller molecular are build up to form larger molecules and this requires the input of energy.

Examples are;

Glucose is used as the primary fuel for energy

Excess glucose is stored as glycogen in the liver and muscle.

Excess glucose is converted to fatty acids and stored as part of the triglyceride molecule in adipose tissue

Excess tatty acids combine with glycerol to form which are stored in adipose tissues.

All these processes requires the build up of smaller molecules to larger molecules and requires input of energy.
