For this question, we are being asked which one of these items uses pseudopods to engulf food.
00:07
First of all, we'll have to determine which of these are cells and which aren't, because non -cells, they don't eat.
00:12
They're not alive.
00:13
They don't need to use the pseudopods.
00:16
Of these, it looks like two of them aren't cells.
00:20
Histomines are a kind of signaling molecule or a kind of chemokine that immune cells use, specifically mast and blast and neocinophil cells will secrete them.
00:29
So it's not histamines.
00:32
Antibodies, they're those, i'm sure you've seen them, the little y -shaped molecules that will bind to various antigens, but they are not a cell.
00:41
So they can't use pseudopods.
00:44
The rest of these are cells.
00:53
Now, which ones are the ones that we are looking for? let's take a look at their function.
00:59
What do t -lenticides do? they, you know, if they're cd8, plus they kill cells, infected ones.
01:11
If they're cd4, they will not kill cells, but they will help regulate the immune response...
