The type of glial cells are particularly at risk from the disease are the Schwann cells. This disease is caused by a bacterium, Corynebacterium diphtheriae, and is caused when the bacteria releases a toxin, or poison, into a person's body. The Schwann cells produces insulating myelin sheath that covers the axons of many neurons. These cells may suffers immune or toxic attacks with diphtheria infection.
Answer:
Homeostasis is the state of steady internal, physical, and chemical conditions maintained by living systems
Explanation:
(A property of cells, tissues, and organisms that allows the maintenance and regulation of the stability and constancy needed to function properly)
The correct answer is: a. A site in DNA that recruits the RNA Polymerase
Promoters are regions of DNA molecule located near the transcription start codons of genes, usually upstream on the DNA with the function to initiate DNA transcription. Promoters contain specific DNA sequences (e.g. TATA boxes) that are binding sites for the enzyme RNA polymerase and transcription factors that recruit RNA polymerase. Transcription factors can regulate gene expression and act as activators or repressors depending on sequences that attach to specific promoters.
Answer:
Option B, ionic bonds; salt
Explanation:
All medicines either in the form of pills or liquid interact with our body by forming a bond with target specific receptors. For instance if a pain killer is taken then it shall form bond with receptors produced by pain and inflammation
So medicines are basically chemical which interact with biomolecules such as enzymes, nucleic acid, hormones, ions etc. by forming ionic bond, hydrogen bond, van der wall force etc. in the active site of enzyme.
These salt molecule remain stable in normal conditions but as they come in contact with digestive system of the body (with different pH) they release the drugs
Hence, option B is correct
<span>The answer would be: a. inflammation is accompanied by an increase in peristaltic movements of his small intestine.
The pathogen will attract the white blood cells that will induce inflammation in the intestine. Inflammation of the intestine will cause increased permeability and increased bowel movement, makes the food transit time reduced and lead to diarrhoea. This mechanism is beneficial since it can help the intestine to "flush out" pathogen of toxins that induce the inflammation.</span>
