The classes under Protista consists of Chrysophytes, Dinoflagellates, Slime moulds, Euglenoids and protozoans. These organisms are all unicellular. They are all the eukaryotic organisms. Euglenoids are photosynthetic where the protozoans are consumers and Slime moulds are saprophytic. They prefer to live in water or moist lands.

Explanation:
TATC is being inserted into the sequence
Answer: A protein acts as a pump and moves calcium ions from an area of low concentration to an area of high concentration.
There are primarily two types of the transport system which occurs through the cell membrane. These are Active transport and passive transport. Active transport facilitates the movement of substances from a medium of lower concentration to a medium of higher concentration. Energy is required for the movement of substances against the concentration gradient. This is accomplished by ATP ( adenosine triphosphate) powered pumps or some other source like an electrochemical gradient.
On the other hand, in passive transport, substances move from a medium of higher concentration to lower concentration.
As 
ions are moving from low to higher concentration via protein pump, therefore, it accurately describes the movement through active transport.
Answer:
Chicken pox, Tuberculosis, etc.
Explanation:
Chickenpox was caused by a infectious agent by inoculating volunteers with vesicular fluid from a patient with acute varicella.
Tuberculosis originated from East Africa and is caused by poverty,HIV infection, homelessness, substance abuse,organ transplants,etc. It can also be transmitted by air if you are near and breathe the same air as someone with Tuberculosis you can get it.
