Your answer is correct, Vasoconstriction
Hello there!
Well, that sentence is easy to memorize because it is short. Compare to what I have to memorize :)
How can I remember the definition?
Well, personally, I used different strategies to study Biology.
The first one "Flashcards".
Not every students like flashcards, but I do. In front of the card, you write "Gene". Then at the back of the card, you write the definition of it.
You keep reading it for like 3 times then you'll remember it.
Another strategy I used it writing it down. And this comes after you finished with the flashcards.
Take a piece of paper and write the definition down without looking at the flashcard. Write it down several times.
The next strategy is to test yourself. Leave it for like 4 minutes and go do something else. (Personally, I usually listen to music).
Then after 4 or 5 minutes, come back to it. Without looking at the flashcards or the paper, try to repeat the definition in your mind. Then repeat it out loud. Then write it down again to see if you remember the correct grammars. For example, you might don't remember how to spell "Chromosome".
That should be enough! :)
I used these tips to study Anatomy and some other science stuff. It works for me. I hope it works for you too.
As always, it is my pleasure to help student like you!
Answer:
Penicillin binds and inhibits bacterial enzyme DD-transpeptidase.
Explanation:
Penicillin is made up of 4 rings of β-lactam and acts by binding to DD-transpeptidase of bacteria. The DD-transpeptidase facilitates the cross-linking of the peptidoglycan cell wall of bacteria. This leads to malformation of the protective cell wall of the bacteria and causes it to lyze and die.
Water would move out of the cells of the microorganisms by osmosis and the cytoplasm would become dehydrated, killing the cells.
The brine is a hypertonic solution, thereby "pulling" the water out of the bacterial cells.
