I know that Malaria is a pretty common mosquito disease in some continents like Asia and Africa... With that in mind..

1.) Is there a cure for Malaria? If so, what is it?

2.) How many people die from Malaria each year? (Please show the statistics for men, women, and children.)
Uhh...
1.Antiparasitics. And I think antimalarial drugs are a thing too. Pretty sure the specific one would depend on each case, but common ones would include: chloroquine, dihydroartemisinin, daraprim (I only remember the brand name for this one, oops), qualaquine (again, only remember brand name), and mefloquine (<-- not sure, I may just be guessing --quines at this point). 2. Don't know. Probably around a million, and I think most are children.

Could we start this up again?

Name a heterotrophic organism that possesses plastids.

Hi!
Most bacteria have plasmids!

Question: Scientists have been trying to find a cure lately for HIV. Recently, there has been a treatment called "cocktail", which has been found to be effective. Describe how this treatment fights against the HIV virus.

In my question I wrote plastids, which are small, complex organelles with more than 2 membranes that were created by endosymbiosis. Chloroplasts are the most famous examples, but they are not found in heterotrophs

The answer I was going for was apicomplexans (formerly sporozoans) which are animal-like protists. They possess a type of plastid called an apicoplast.

-
"Cocktail" is a combination of drugs that each attacks the virus differently. I think there are six different types, but I don't remember them. And I don't think it's actually a cure--the goal is just to get the virus count low enough to not cause symptoms.

answer
Monotrichous: 1 flagellum on one end of the cell. Amphitrichous: 1 flagellum on each end of the cell. Lophotrichous: 1 or more groups or tufts of flagella. Peritrichous: flagella distributed relatively uniformly around the cell (cell envelope technically).

You're right, I'm sorry. I edited it to fix.

What does CLSM stand for and how does it work?

Answer
CLSM stands for Confocal Laser Scanning Microscope. Unlike regular microscopes, it uses a laser rather than light to obtain an image. It uses a pinhole to remove "out-of-focus" light. Whereas with a regular microscope, you either see the surface or deep within the cell but not both, the confocal microscope allows you to see multiple levels of the specimen allowing you to form a 3D image of the specimen.
