Eosinophils are most likely to be involved in an allergic reaction in mammals regardless of species. However, mast cells can also be involved.

What stage of the cell cycle is the nucleolus always visible?
The nucleolus is always visible during interphase, particularly during the G1, S, and G2 phases of the cell cycle. This is when the cell is actively growing and synthesizing proteins.
What is a type of cell that does divide actively?
A meristematic cell
What phase of cell division is the cell not dividing?
During the interphase stage of the cell cycle, which includes G1, S, and G2 phases, the cell is not actively dividing. Instead, it is preparing for cell division by growing and replicating its DNA. It is only during the M phase, which includes mitosis and cytokinesis, that the cell actually divides.
What what happens during interphase?
the chromosomes are duplicated.
What activities are going on in the cell during interphase?
During interphase, the cell is actively growing, carrying out its normal functions, and preparing for cell division. DNA replication occurs, resulting in each chromosome being duplicated. Additionally, organelles are also replicated during this phase.
Why does penicillin kill only actively multipling cells and lysozyme will kill cells in any stage of growth?
Penicillin targets actively multiplying cells by inhibiting cell wall formation during division. Lysozyme can kill cells at any stage of growth because it disrupts the bacterial cell wall by breaking down peptidoglycan, a key component of the cell wall, leading to cell lysis.
How oxygen is passed from a red blood cell to an actively respiring muscle?
The oxygen passes through a bloodvessel called artery to an actively respiring muscle cell.
Animal cells actively replicate their genetic material during?
Animal cells actively replicate their genetic material during the S phase of the cell cycle, which occurs prior to cell division. This process ensures that each daughter cell receives a full set of DNA and genetic information.
What actively regulates what enters and exits the cell?
the bladder
Which cell is most actively photosynthesising?
[object Object]
If you were examining a skin cell during one complete cell cycle which phase would you never observe?
You would never observe the G0 phase. Skin cells typically do not enter the G0 phase since they are actively dividing to replenish the skin. The G0 phase is a resting phase where cells are not actively dividing.
What process is used by some protists to actively ingest food particles?
Some protists use a process called phagocytosis to actively ingest food particles. During phagocytosis, the protist surrounds the food particle with its cell membrane and forms a vesicle, called a food vacuole, to bring the food particle into the cell for digestion.
