The answer is an envelope.
A virus is an infectious agent that can replicate only inside a host cell. When it is outside the cell, it consists of genetic material coated with protein capsid. Some viruses also have an envelope which covers capsid. The function of the envelope is to identify and bind some receptor sites on the host membranes. After fusing with the cell membrane, it allows to capsid and genetic material to enter the cell and infect it.
I would say to divide 968÷250..I dk but iw would
Hi!
The answer would be B. Positive
Explanation:
A positive feedback mechanism is that in which a stimulus induces an output which in turn functions to magnify the same response <em>(acting as a stimulus to itself). </em>
As in this case, Ethylene acts as a stimulus for fruit ripening (<u>response</u>). When it is released during fruit ripening, it stimulates nearby fruits to ripen (<u>response</u>), which in turn acts to stimulate further fruits to ripen (<u>response</u>), resulting in the effect being widespread (<u>magnified</u>)
Hope this helps!
Answer:
It must be large particles move into cells, unless there is another option
Explanation:
Passive transport does not require energy, so the first one is incorrect
Particles are moved from areas of high concentration to an area of low concentration, so the last one is also incorrect
So it should be large particles can move into cells, unless of course there is another option
