the correct statement would be cell p also has a cell membrane.explanation:
chloroplasts are the organelles responsible for capturing light, and since these are only present in plant cells. animal cells lack chloroplasts and cannot capture light, so if cell p does not capture light, it would not be a plant cell, but an animal cell.
cell q has cytoplasm, but no chloroplast. again, chloroplasts are absent in animal cells, but present in plant cells, so cell q must also be an animal cell.
this rules out the first three options because a large vacuole and cell wall are general characteristics of plant cell. cell membrane is present in animal cells, and hence the fourth option "cell p also has a cell membrane" is correct.
hope this !
- because there is an inverse relation between altitude and the number of gas molecules striking the outer surface of the bottle (pressure exerted on it).
- therefore, when the bottle is taken to lower altitude, the number of gas molecules striking the outer surface of the bottle increases and so changing its shape..
periods go left to right or horizontally. groups are a name for the vertical columns in a periodic table. each column is called a group. the elements in each group have the same number of electrons in the outer orbital.
the answer is by adding the vectors.

the river current is moving with velocity vc=10 km/h in a certain direction relative to the shore. the boat is moving with velocity vb=10 km/h relative to the current, and in the same direction as the current, so the total velocity of the boat relative to the shore will be equal to the sum of the two vectors (because they are in the same direction):
v=vb+vc = 10 km/h + 10 km/h = 20 km/h
co(s) + 2h+(aq) = co2+(aq) + h2(g)
