Answer:
1st question Answer choice B, either A or B for question 2.
Explanation:
I said either A or B because for some people its hard for there grades to go up so it takes them longer and for answer choice A its hard for people to write so id say either A or B
Answer:
Digestive system breakdown small proteins into amino acids by chemical digestion using enzymes (option B).
Explanation:
One of the main functions of the digestive system is to degrade food to facilitate its absorption at the intestinal level. This degradation has a mechanical phase, which includes chewing and contracting the stomach, and an enzymatic phase.
The enzymes that allow the breakdown of proteins into amino acids are called proteases, or peptidases. They are enzymes capable of breaking peptide bonds, obtaining at the end amino acids that can be more easily assimilated by the organism.
<em>The other options are not correct because </em><u><em>mechanical digestion</em></u><em> reduces the size of the digested food and mixes it with the gastric juices, but does not break the peptide bonds.</em>
Hey! Let's break it all down!
Methicillin: It is an antibiotic formerly used in the treatment of bacterial infections caused by genus Staphylococcus. It's a semisynthetic derivative of penicillin. It contains a modification to the original penicillin structure that makes it resistant to an enzyme called penicillinase.
Resistant: Pertaining to the ability of a microorganism to remain unaffected by and antimicrobial agent. Or a lack of response to, or of influence by, a pathogen, toxin, treatment, or other stressors.
Staphylococcus aureus: Well, it is a type of bacteria. It is apart of the Staphylococcaceae family. It is a very bad bacteria to have as it can cause infections.
2. Alright. Let's see if this is correct.
1st Link: Infectious Agent.
2nd Link: Reservoir.
3rd Link: Portal of Exit.
4th Link: Route of Transmission. (Can only be spread through direct contact with infected material.)
5th Link: Portal of Entry. (Enters the body through open wounds, sores and such.)
6th Link: Susceptible Host
Signs and symptoms of MRSA could be:
Minor skin infections.
Boils, Cellulitis Folliculitis, Carbuncles.
Scalded Skin Syndrome and Abscesses.
Lung Infection or Pneumonia.
Brain Infection or Meningitis.
Bone Infection or Osteomyelitis.
Heart Infection or Endocarditis.
Life threatening blood infections or TSS (Toxic Shock Syndrome.)
Finally, the first way to break the chain of transmission is to simply block out the route of transmission, since this bacteria can only be spread through direct contact with infected material, doing things such as washing hands regularly, cleaning and covering wounds, taking antibiotics if they are prescribed can help break that chain of transmission.
Another way is to not come in contact with direct contact to people who do have it. This may sound obvious, however the MRSA bacteria would eventually leave the host through open sores or wounds. Meaning it is probably the best to stay away from them, so it doesn't transmit to you or others.
Last but not least. You can block its Portal of Entry. By quickly taking care of any type of injuries on your body and with the right treatment, you can quickly block off the Portal of Entry before it can be transmitted to you.
Have a nice day!
