A student investigated the effect of different concentrations of sugar solutions on some potato cylinders. He took a large potato and used a cork borer to cut out several cylinders, each exactly the same diameter. He trimmed the peel off the ends of the cylinders, and then cut them into exactly 1 cm lengths.
He then measured the
mass of each piece.
He placed one piece of potato in each of six beakers. He then covered each piece with either water, or one of five
different concentrations of sugar solution. He used the same volume of solution in each beaker.
The student left the potato pieces in the beakers for 30 minutes. Then he removed them from the beakers, blotted
them dry with filter paper and measured their mass again.
These were the results he wrote down.
Before piece A = 5.2g piece B = 5.1g
piece C = 4.9 g
piece D = 5.0g piece E = 5.1g
piece F = 5.2g
Solutions A, distilled water B, 0.1% sugar solution C, 0.2% solution
D, 0.5% solution E, 0.8% solution
F, 1.0% solution
After A = 5.5g
B = 5.2g
C = 4.99
D = 5.3g
E = 5.0g
F = 5.0g
a In the space below, draw a results table and fill in the student's results. Include a row or column showing the
change in mass. Take care to head each column and row fully, with units.

mountains can affect the climate of nearby lands. in some areas, mountains block rain, so that one side of a mountain range may be rainy and the other side may be a desert. much of airborne moisture falls as rain on the windward side of mountains.

explanation:

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products

answer: grassland biomes are closer to the equator and receive more rain.

grasslands are biomes that are dominated by grasses rather shrubs and trees. savanna are biomes that exhibit grasses, shrubs and small tree as vegetation. grasslands are located near the equator of the earth. these are found in north america. savanna biomes are found in africa, south america, australia and india. grassland exhibit moderate climatic conditions, it receives   amount of rainfall higher than savanna.   therefore, savanna exhibit dry and hot climatic conditions.

protein makes up the building blocks of organs, muscles, skin, hormones and pretty much everything that matters in your body.

some choices are:

peanut butter

seeds

eggs

yogurt

meats

fish

so pretty much meat, dairy, nuts, and grains.
