Answer:
I think is the second one
Answer:
Explanation:
Water tends to move in nature. This movement is facilitated by an osmotic gradient created as a result of OSMOSIS. Osmosis is the movement of water from a region of low solute concentration (high solvent concentration) to a region of high solute concentration (low solute concentration) through a semi-permeable membrane.
Salt contributes to the tonicity of the soil it was sprinkled in the sense that it makes the solute concentration of the soil higher (hypertonic) than that of the plant cell (hypotonic). This creates an osmotic gradient causing the movement of water from the plant cell into the road containing salt in order to form an osmotic balance. The water passes through the cell membrane of the plant cell which acts as the semi-permeable membrane in this case.
The movement of water out of the cell will eventually make the plant cells around that road area shrink (reduce) and likely die, due to loss of water content.
Answer: It shows a diagrammatic representation of biomass at different tropic levels in an ecosystem
Explanation:
Goat eat grass. The goat are in turn eaten by the Man. The grass has the greatest biomass in this chain. Its biomass, therefore, sits at the bottom of the pyramid. Conversely, the man has the lowest biomass in the chain and hence sits on top of the pyramid.
Answer:
The correct option is;
7:32 AM
Explanation:
The information given are;
The time at 45 degrees W and 72 degrees N = 9:32 AM
The variation of time with lines of longitude is given as 15 degrees for each 1 hour variation, therefore, where we have the other location at 75 degrees W and 45 degrees S, the difference in the longitude = 75 - 45 = 30 degrees west of the initial location
Moving west is in the opposite direction of the Earths rotation, therefore, we subtract 1 hour for every 15 degrees giving 30/15 = 2 hours subtracted
The time at 75 degrees W and 45 degrees S is therefore, 9:32 AM - 2 hour = 7.32 AM
The latitude of a place left out in the calculation of the relative time of a place.
