Explanation:
An antibiotic made by microorganisms and modified by chemists is called. semi-synthetic. The antimicrobials produced by some molds and bacteria are generally called. antibiotics
Histamines are chemicals released by the body as an allergic response.They help the body by reacting when their are "intruders" so when enters, histamine acts as a messenger and sends out a signal for the body to create a reaction helping to get rid of teh intruder through some type of reaction.
Answer:
B = hydrogen bonding
Explanation:
The water molecule consist of two hydrogen atom one oxygen atom. There is large electronegativity difference between oxygen and hydrogen. Both atoms are bonded through covalent bonds.
Covalent bond:
It is formed by the sharing of electron pair between bonded atoms.
The atom with larger electronegativity attract the electron pair more towards it self and becomes partial negative while the other atom becomes partial positive.
For example:
In water the electronegativity of oxygen is 3.44 and hydrogen is 2.2. That's why electron pair attracted more towards oxygen, thus oxygen becomes partial negative and hydrogen becomes partial negative. The partial positive end of one water molecule attracted towards the partial negative end of other moleucle. The attraction between them is called hydrogen bonding. In this way large mole are connected with each other. Hydrogen bonding is actually a weak bonding.
Because bacteria could get on our hands through out eyes, ears, mouth, or nose (since all of which is noted to be connected to one another) and it could make you extremely sick. Although some bacteria is good for you, an extreme amount can make you extremely sick.
For example, you can contract ecoli and if that's not treated it can be fatal because you lose a ton of fluid and nutrients! Good luck, rockstar. I hope this is what you were looking for, and you pass! (:
