An E. coli F(+) cell

Phantasy [73]

Answer:

The correct answer will be option- C.

Explanation:

The bacteria can transfer its genetic material through three processes: transformation, conjugation and transduction. The process of conjugation takes place through the formation of the conjugating tube formed of the pili, the membrane extensions of the bacteria.

These pili are known as fertility pili or F-pili as they transfer the F-plasmid or fertility plasmid from the F⁺ bacteria containing the F-plasmid to the F⁻ cells or the bacterial cells which lack the F-plasmid.

Thus, option- C is the correct answer.

Explain how super-antigens, such as toxic shock syndrome toxin produced by staphylococcus aureus, often lead to the development

GaryK [48]

Toxic shock syndrome toxin is a super-antigen produced by Staphylococcus aureus bacteria .it causes toxic shock syndrome by stimulating the release of large amount of interleukin-1, interleukin-2 and tumor necrosis factor .

Interleukin-1:

It is a group of 11 cytokines that plays a central role in the regulation of immune and inflammatory responses to infections .

Interleukin-2:

It is a type of cytokine signaling molecule in the immune system .interleukin-2 is apart of the body's natural response to microbial infection and in discriminating self and non self foreign.

tumor necrosis factor :

Tumor necrosis factor is protein superfamily of type 2 transmembrane protein containing tnf homology domain and trimers .these proteins are expressed predominantly by immune cells and they regulate diverse cell functions ,including immune response and inflammation ,but also proliferation, differentiation and embryogenesis.

Staphylococcus aureus:

Staphylococcus aureus is a gram positive pathogen cable of producing a variety of bacterial exotoxin known as super antigens .

Toxic shock syndrome :

Toxic shock syndrome is an acute disease mediated by the production of super-antigenic toxin .it is rare , life threatening complication of certain type of bacterial infections. often it results from toxins produced by staphylococcus aureus bacteria but the condition may also be caused by toxins produced by group a streptococcus bacteria.

Toxic shock syndrome can affect anyone ,including men , older woman, children and postmenopausal women.risk factors of toxic shock syndrome includes skin wounds ,surgery ,and use of tampons and devices such as menstrual cups contraceptive devices ,etc.

Symptoms of toxic shock syndrome toxin:

A sudden high fever,low blood pressure ,vomiting or diarrhea ,rash resembling sunburn ,muscle aches ,redness of eyes ,mouth and throat ,headache and seizures.

Conclusion:

If you have these symptoms of toxic shock syndrome then immediately call your doctor or consult a doctor and take precautions.

When the cap of an average gilled mushroom is cut off and shaken, a cloud of powdery material is released. The material released

lys-0071 [83]

Answer:spores

Explanation:

Fungi are eukaryotes .they do not possess chloroplast.as a result they

are heterotrophs that feed on dead and decaying matter.mushrooms are a type of fungi. They consists of individual filaments collectively called hyphae, which form the mycellium. They form visible fruiting bodies above the ground. This body is umbrella shaped and is called the pileus.

Underneath the pileus are gills ,from where the spores drop.

Mushrooms produces spores as a means of reproduction. When the spores are released ,they are carried by agents of dispersal such as water,air etc.when fall on favourable substrates, they germinate to form a single hyphae which then branches to form mycellium.

Though not all tumors or polyps bleed, occult blood in the stool may be an indication of colon cancer or polyps in the colon or rectum.

<h3>What causes occult blood in stool the most frequently?</h3>

Small bowel tumors, esophagitis, peptic ulcers, gastritis, inflammatory bowel disease, vascular ectasias, portal hypertensive gastropathy, and colon cancer are a few of the more prevalent causes (eg, GI stromal cell tumor, lymphoma, carcinoid, adenocarcinoma, or polyp)

If the fecal occult blood test results are positive, blood has been discovered in the stool. Your doctor will need to identify the cause of the bleeding, either by doing a colonoscopy or by performing an examination to establish if the stomach or small intestine is the source of the bleeding.
