Answer:
Option c (No, T cells left from the previous infection can kill any virus.
)
Explanation:
When ever viral infection occur, body's immune system start to fight against it by activating B-cells and T-cells.
B-cells produce antibodies that bind with virus and act as label. This label indicate virus as foreign substance. Hence T-cells recognize it and kill it. Furthermore, B-cells form memory cell that keep the viral memory. if this viral infection occur again in future, T-cell recognize it and eliminate the virus.This mechanism is called immunity.
Explanation:
The structure relates to their function
Their structural components (i.e. their makeup) determine their function (what they do). In specific cell types, collected proteins may function as a unit called an organelle.
Further Explanation:
In all eukaryotic cells mitochondria are small cellular organelles bound by double membranes make most of the chemical energy required for powering the biochemical reactions within the cell. this chemical energy is stored within the molecule ATP which is produced.
Some organelles are bound by membranes like those that make up the external structure of the cell, with varying compositions of phospholipids and proteins. These are advantageous, as they
- may increase metabolic reaction efficiency;
- they allow cells to concentrate smaller fractions of enzymes and solutes separate proteins and molecules that may harm the cells by parceling them into membrane-bound organelles
- for example, hydrolytic enzymes concentrated within vacuoles may degrade macromolecules like DNA and RNA within the cytoplasm.

Yes, malaria is spread through inspect bites or stings and can possibly be spread through unsanitary needles. Therefore, malaria is HIGHLY contagious and can be spread through even a SINGLE DROP of blood.
