when a neutrophil detects a bacterial pathogen, where do Rac and Rho signaling proteins become activated?

Answers

Answer 1

Answer:

Neutrophils do not have memory of any pathogen. They attack any pathogen indiscriminately, not selectively. This is why they belong to the innate (non-specific) arm of the immune system.

Memory T- cells are lymphocytes that are specifically produced and act against pathogens that were encountered at least at one time before. The memory of that encounter is kept and when the same kind of pathogen is encountered a second time, it is remembered by these cells and they very specifically single it out and destroy it. These cells belong to the specific or adaptive arm of the immune system.

List the key differences between mitosis and meiosis please!

Answers

KELPEL (again)!!!

This is easy:

When reproducing, mitosis can reproduce two different ways: sexually and asexually. I personally find this to be very interesting. :P
Mitosis allows DNA to replicate only one time for cell division.
In mitosis there is no synapsis.

Meiosis on the other hand is more complicated.
In meiosis this allows DNA to replicate twice for cell division.
Meiosis includes synapsis.
When reproducing, meiosis only allows sexual reproduction.

There, I'm finally done. xD

Hope this helps!

The differences between Mitosis and Meiosis is as follows:

·Mitosis has only one round of genetic separation and cellular division, while Meiosis has two.

·Daughter cells in Mitosis are genetically identical to both parent cells, and each other, whilst Daughter cells in Meiosis are not.
