What Cytokines that make cells resistant to viruses?
Interferons
Do lysosomes make steroid hormones?
No lysosomes do not make steroid hormones. Lysosomes are organelles that are found in the cells of animals. Steroid hormones are made by estrogen and testosterone.
What is the difference between cells and viruses?
Virus: is a strand of hereditary material surrounded by a protein coating that can infect and multiply in a host cell. Host Cell: a living cell invaded by or capable of being invaded by an infectious agent.
What does a virus ultimately do to the host cell?
After leaving the host cell, the virus goes to insert its DNA into even more cells. After a while, there are thousands of cells with the DNA of the virus. With that DNA, the cells make more viruses. There are two cycles for this; Lytic and Lysogenic.
Do viruses replicate in cells of organisms?
Yes. This is the reason that viruses infect cells. The virus injects its genetic material, either DNA or RNA, which then takes over the cell's activities and turns the cell into a virus factory, causing the cell to make new virus parts and assemble them. Eventually the cell ruptures and the new viruses are free to infect other cells.
What Cytokines that make cells resistant to viruses?
Interferons
Why do viruses make us sick?
A virus will make us sick because it disrupts the function of the cells or actually kills cells. Viruses uses healthy cells in order to replicate.
What structure is is a group of cells that make hormones?
I rock
Do lysosomes make steroid hormones?
No lysosomes do not make steroid hormones. Lysosomes are organelles that are found in the cells of animals. Steroid hormones are made by estrogen and testosterone.
A group of similar cells that make hormones are called?
endocrine tissue
What is a circulating hormone?
Most endocrine hormones are circulating hormones, they pass from the secretory cells that make them into interstitial fluid and then into the blood. circulating hormones are carried through the bloodstream to act on distant target cells. Paracrines act as neighboring cells, and autocrines act on the same cells that produced them.
What are viruses hidden in?
Cells, they reproduce by invading a cell and using its functions to make more viruses, eventually killing a cell. That's why viruses are bad, and that where they "hide".
What do the T-cells do?
If im correct, helper t-cells activate: b-cells that mark viruses and make them stick together, killer t-cells --which attack macrophages and infected cells, and memory b-cells, which remember how to stop viruses, this i believe is called active immunity

Are viruses a solid liquid or gas?
A virus is a solid but very tiny particle. It high jacks another cells to make more viruses.

Are hormones target molecules or signal molecules?
Hormones affect target cells because target cells have receptors that bind with certain hormones (they're specific). If a cell does not have a receptor then it is not affected by hormones. Target cells (which do have the receptor for a particular hormone) would be affected by the hormone.
