Show the following as a food chain: omnivore, autotroph, herbivore
Thepotemich [5.8K]

omnivore⇒herbivore⇒autotroph

this is because an autotroph makes its own food (photosynthesis) so it doesn't have the need to eat other organisms. Herbivores eat only plans (remember this with the word herb is a type of plant) and an omnivore will eat either meat or plants so it can eat either of the things below it.

What 3 functions do proteins have in a plasma membrane?*
Aliun [14]

Answer:

Explanation:

Proteins in the plasma membrane have several functions based on their components, location etc. For instance, if the protein transcends the entire plasma membrane it could be a transport protein, responsible for the import and export of certain molecules between the cell and the extracellular matrix (ECM). If the proteins are resting at the surface of the cell, facing the ECM, their role could be to detect components in the ECM, relaying a series of messages back to the nucleus so that the cell can ‘decide’ what it should do with this information (is it being told it should undergo apoptosis, should it begin to divide, should it migrate?). As well as this, it could be involved in the detection of foreign bodies such as pathogens. This is an extremely job for these proteins because if the cell does come in contact with a pathogen, the cell can use these proteins to engulf the pathogen and through a series of steps, present the antigen on their major histocompatibility complexes (either 1 or 2 depending on the cell type) or HLA’s for human cells. Thus it can be concluded that protein functions vary widely in the plasma membrane and due to the vast number of proteins that can be found there, it’s difficult to narrow down the exact main of functions of all these proteins put together.

What happens during the lytic cycle of a viral infection?
mina [271]
1) Bacteriophage injects its DNA into the host cell
2) The DNA circularises
3) Viral gene activates the host cell's DNA synthetic machinery
4) Rapid reproduction of viral DNA occurs
5) Host makes viral capsomeres, allowing viral assembly to take place
6) Due to the large volume of new bacteriophages inside the host cell, the cell splits (cell lysis), releasing the new bacteriophages
