Answer:
1. C
2. B
Explanation:
1. When a plant cell looses some water due to dehydration or being placed in a hypertonic solution, the term used to describe the cell's intial, not severe shrinkage is 'flaccid'.
Here, it's clear that the cell shrank so much that the cell membrane pulled away from the cell wall. The correct term for this severe shrinkage is 'plasmolysed'.
We don't use 'wilted' as a term to describe a cell. We use it to describe the plant as a whole.
2. This is the function of each. Water and ions in xylem and sugars like sucrose in phloem.
I’m guessing Asia and North America to be closer
Given:
m = 12 g, the mass of the cylinder
r = 2 cm, the radius of the cylinder
h = 6 cm, the height of the cylinder.
Calculate the volume, V, of the cylinder.
V = πr²h
= π*(2 cm)²*(6 cm)
= 75.398 cm³
By definition,
density = mass/volume.
Therefore,
density = m/V
= (12 g)/(75.398 cm³)
= 0.159 g/cm³
= 0.16 g/cm³ (nearest hundredth)
Answer: 0.16 g/cm³
Answer:
Pseudopodia are temporary and cytoplasm-filled parts of the cell membrane that are able to change their form in order to move.
Explanation:
Pseudopodia are temporary and cytoplasm-filled parts of the cell membrane that are able to change their form in order to move. They are used in some eukaryotic cells to move around or to eat. Most cells that do this are called amoeboids. The amoeba is a common example. ... Pseudopods can also capture prey by phagocytosis.
