From the given below list, transgenic models exist for which one of them:-

zoology health and diseases diabetes mellitus lifestyle diseases non-infectious diseases

  1. Cancer

  2. Crystic fibrosis

  3. Rheumatoid arthitis

  4. Alzheimer's

Show answer
Correct Option: A
Explanation:

Transgenic models are genetically modified organisms in which the genome has been altered through random integration of gene sequences.

Mouse, Rat, Cell genome are some types of models used for cancer treatment.
So, the correct option is 'Cancer'.

Which branch of biology is helpful in prevention of cancer by identification of certain genes

zoology health and diseases diabetes mellitus lifestyle diseases non-infectious diseases

  1. Cryobiology

  2. Teratology

  3. Molecular biology

  4. Gerontology

Show answer
Correct Option: C
Explanation:

Cryobiology is the branch of biology that deals with effects of low temperatures on living things. Teratology is the branch of science which deals with the study of congenital abnormalities and abnormal physiological development. Molecular biology is the branch of biology which deals with the the structure and function of the essential macromolecules. The major application of molecular biology to prevention and early detection of cancer and other diseases by identification of certain genes. Gerontology is the branch of science which deals with the study of old age, the process of ageing and the problems of aged people.

Thus, the correct answer is 'Molecular biology.'

Which is most common chromosomal aberration seen in cancer-

zoology health and diseases diabetes mellitus lifestyle diseases non-infectious diseases

  1. Deletion

  2. Invention

  3. Duplication

  4. Translocation

Show answer
Correct Option: A
Explanation:

A deletion mutation occurs when part of a DNA molecule is not copied during DNA replication. This uncopied part can be as small as single nucleotide or as much as an entire chromosome. The loss of this DNA during replication can lead to genetic disease.

So, the correct option is 'Deletion'.

Cancer cells differ from non-cancerous cells, because

  1. They have elevated levels of telomerase

  2. Theya are virtually immortal

  3. They have the ability to resist apoptosis

  4. They can maintain the telomere length as they divide

Show answer
Correct Option: C
Explanation:

One of the hallmarks of human cancers is the intrinsic or acquired resistance to apoptosis. Evasion of apoptosis may contribute to carcinogenesis, tumor progression and also to treatment resistance, since most current anticancer therapies including chemotherapy, radio- and immunotherapy primarily act by activating cell death pathways including apoptosis in cancer cells.

Therefore, the correct answer is option C.

The bacterial disease cholera is accompanied by 

some infectious diseases infectious diseases health and diseases biology

  1. Peptic ulcers

  2. Rapid loss of fluid from the intestine

  3. Infection of heart muscles

  4. Rose spots

Show answer
Correct Option: B
Explanation:

Cholera is caused by the bacterium Vibrio cholerae. It can cause severe diarrhea, which comes on suddenly and may quickly cause dangerous fluid loss - as much as a quart (about 1 liter) an hour.
Therefore, the correct answer is option B.

some infectious diseases infectious diseases health and diseases biology

  1. Diarrhoea

  2. Dehydration

  3. Fever

  4. All of the above

Show answer
Correct Option: D
Explanation:
Symptoms may range from none, to mild, to severe fever. The classic symptom is large amounts of watery diarrhea that lasts a few days. Vomiting and muscle cramps may also occur. Diarrhea can be so severe that it leads within hours to severs decreased skin elasticity, and wrinkling of the hands and feet. The dehydration may result in the skin turning bluish. Symptoms starts two hours to five days after exposure.

So, the correct answer is 'All of the above'.

Which of the following are the symptoms of cholera?

some infectious diseases infectious diseases health and diseases biology

  1. Diarrhea

  2. Nausea

  3. Dehydration

  4. All of the above

Show answer
Correct Option: D
Explanation:

Most people exposed to the cholera bacterium (Vibrio cholerae) do not become ill and never know they've been infected. Yet, because they shed cholera bacteria in their stool for seven to 14 days, they can still infect others through contaminated water. Most symptomatic cases of cholera cause mild or moderate diarrhea that's often hard to distinguish from diarrhea caused by other problems. Symptoms of cholera infection may include diarrhea, nausea and vomiting, dehydration.
