Answer:
presence of sugar means that the outside of the fruits is less dilute (more concentrated in sugar than water) than the inside of the fruits
in osmosis (diffusion of water molecules), water molecules have a net movement from a more dilute substance to a less dilute substance
sugar is the less dilute substance, so water is drawn out of the fruits and mixes with the sugar around them
the sugar dissolves in water, creating a sugar solution
this results in fruits with less water inside them, and surrounded by sugar solution

A car drives 150 m to the east then backtracks 30 m to the west. Describe the mathematical operation you will use to determine the net movement of the car.
Answer:
Subtraction operation
The car's displacement is 120 m west
Explanation:
Given;
first motion of the car as 150 m east
second motion of the car as 30 m west
The mathematical operation that will be used to determine the net movement of the car is subtraction operation.
The net movement of the car is the car's displacement.
Displacement is given by;
D = final position - initial position
D = 30 m - 150 m
D = - 120 m
The negative sign is direction = west ward direction
Thus, the car's displacement = 120 m west

6
75
375
450
Answer: the carrying capacity for adult giraffes in this area is: 6.
Explanation: [ 450 pounds divided by 75 = 6. ]
Fun Fact - Giraffes can drink up to 10 gallons of water a day and spend 16-20 hours a day feeding, their favorite food is Acacia Leaves.
Adult giraffes eat 75 pounds of food in a day. On average, an area can provide 450 pounds of food per day for giraffes.
The carrying capacity for adult giraffes in this area are 6.
How the carrying capacity for giraffes in given area is determined?Adult giraffes eat = 75 pounds of food per dayArea provides = 450 pounds food per dayso, carrying capacity for giraffes in the area equals,
food provided by are per day\ food eater by giraffes in a day
=450\75
= 6.

how does the concentration of electrolytes in and outside a cell control the movement of water
Answer:
Maintaining an isotonic environment for the cell ensures that the cell does not shrink or swell due to water.
Explanation:
If the cell was in a hypotonic solution, water would rush in the cell causing it to burst, and if it was in a hypertonic solution it would cause water to move out of the cell, causing the cell to shrivel. It is important that the cell is always in a solution with an almost equal electrolyte solution inside the cell

Ancient Greek philosophers spent lots of time thinking about science and imaging explanations for the natural world. What part of the scientific process did they need to do
Answer:
Experiments
Explanation:
The ancient Greek philosophers spent more time philosophising and thinking about scientific explanations to phenomena in the natural world.
How ever, they relied solely on reasoning while attempting to explain scientific observations. Contemporarily, science is highly empirical. The scientific process can only be complete when scientific observations are subjects to rigorous experiments in order go determine the actual relationship between variables and provide better explanation for scientific observations.
Hence the ancient Greek philosophers should have used experiments rather than sole reason in proffering scientific explanations to natural phenomena.
Answer:
Experiments
Explanation:
The ancient Greek philosophers spent more time philosophising and thinking about scientific explanations to phenomena in the natural world.
