Answer:
The hormone Oxytocin is produced in the hypothalamus and released into the bloodstream from the pituitary gland. Facilitating childbirth is its main function.
Answer:
Cell membrane is a semi-permeable membrane that surrounds the cytoplasm.
Explanation:
Archea contains only 1 cell and they are prokaryotic organisms. They have a different molecular setting, thus making them different from bacteria.
Cell membrane of Archea:
- In archeal cell membrane, isoprene chains are connected to glycerol lipid monolayer,
- The cell membrane is either lipid bi layer or lipid mono layer.
- Archeal cell wall contains pseudo peptidoglycan.
Cell Membrane of Bacteria:
- In bacteria, the fatty acid chains are linked to glycerol.
- The cell membrane is a lipid bilayer.
- Bacterial wall contains peptidoglycans.
Answer:
Like healthy cells, cancer cells can't live without oxygen and nutrients. So they send out signals called angiogenic factors. These encourage new blood vessels to grow into the tumour.
Explanation:
<h3>Under this conditions virus might favor lysis instead of lysogeny:</h3>
- according to the state of the host cell (can switch)
- in a healthy host, the virus can multiply and create new virions.
- unhealthy host: Lack of energy permits the lysogen to incorporate DNA into the host cell, where it can wait for the cell's health to improve.
<h3>What is lysis?</h3>
A common result of viral infection is cell lysis. Cellular membranes are damaged, which causes cell death and the release of cytoplasmic substances into the extracellular environment.
<h3>What is lysogeny?</h3>
One of two viral reproduction cycles is lysogeny, sometimes known as the lysogenic cycle. The bacteriophage nucleic acid is integrated into the host bacterium's genome during lysogeny, or a circular replicon forms in the bacterial cytoplasm.
