4.Sam and John were arguing in a group about osmosis. Sam said that osmosis is when water moves across a cell membrane from an area of higher concentration to an
area of lower concentration. John says that it is when water moves across a cell
membrane but from lower concentration to higher concentration. Who is correct and
why are they correct? (S7L2a)
A. John is correct because he said that water is moved across the cell membrane
and then describes active transport and osmosis is an example of active
transport
B. Sam is correct because he said that water moves across a cell membrane from
an area of high concentration to lower concentration,
C. John is correct because he said that water moves from lower concentration to
higher concentration.
D. Neither is correct because osmosis has nothing to do with water

Sam said that osmosis is when water moves across a cell membrane from an area of higher concentration to an. membrane but from lower concentration to higher concentration.

Explanation:

white blood cells or wbc s are mainly 2 types-

1.agranulocytes

2.granulocytes

the monocytes or macrophages of agranulocytes , dendritic cells which are accessory leucocytes, and b cells which is one type of lymphocytes   identify the antigens present on the pathogen's surface. these three cells are called antigen presenting cells(apc) which are phagocytes and destroy the antigens by secreting antitoxins. besides this leukocyte is always plays vital role in the immunity of the body.

the answer is admiramos

the rule for verbs is whoever you are referring to (in this case 'nosotros'), you need to change the ending of the word.

nosotros - amos

yo - o

tu - as

el, ella, usted - a

ellos, ellas, ustedes - an

(examples: nosotros bailamos (instead of bailar) or yo hablo (instead of habla)
