Answer:
Explanation:
example of osmosis in animals is the shrinking of slugs on exposure to salt. The skin of slugs is a semi-permeable membrane that on exposure to salt, draws out water from the cells resulting in the shrinking of the cell and, in turn, the animal. hope this helps you.
Are starch molecules or glucose molecules bigger?
Answer: Starch
Explanation:
Why is starch larger than glucose? Based on the experiment, starch molecules are bigger in comparison to glucose molecules because they could not leave the tubing. This is supported by the presence of color change in the tubing for the starch test.
Starch molecules are polysaccharides and big sugar molecules, whereas glucose is a monomeric carbohydrate. Thus, starch molecules are bigger than glucose molecules.
What are starch molecules?Starch is an insoluble carbohydrate that is tasteless and soft sugar with molecular formula, (C₆H₁₀O₅)ₙ. They are categorized as polysaccharides as they are made of more than two sugars linked through glycosidic bonds.
The starch is a complex sugar molecule made of many glucose monomeric units linked by α 1,4 linkages. It is present in food sources and is consumed for energy. On the other hand, glucose is a simple carbohydrate that is categorized as a monosaccharide due to single sugar.
As starch is a polysaccharide and has n number of carbons they have a large molecular weight and structures as compared to the glucose molecule with less molecular weight.
Therefore, starch is a bigger molecule.

Answer: colavent
Explanation:
Using d = m/V, what is the (V)olume of a solid that has a density is 14g/cm² and has a
mass of 7 grams.
Answer:
0.5cm²
Explanation:
the volume is found by dividing the mass over the density
v=m/d
=7g/14g/cm²
=0.5cm²
i hope this helps
Answer:
[tex]\boxed {\boxed {\sf 0.5 \ or \ \frac {1}{2} \ cm^3}}[/tex]
Explanation:
We are asked to find the volume of a solid given the density and mass. The formula for density is:
[tex]d= \frac {m}{v}[/tex]
We know the solid's density is 14 grams per cubic centimeter and the mass is 7 grams.
d= 14 g/cm³m= 7 gSubstitute the known values into the formula.
[tex]14 g/cm^3 = \frac{7 \ g}{v}[/tex]
We are solving for the volume of the solid, so we must isolate the variable v. First, cross multiply. Multiply the first numerator by the second denominator, then the first denominator and second numerator.
[tex]\frac {14 g/cm^3}{1} = \frac{7 \ g}{v}[/tex]
[tex]14 \ g/cm^3 * v= 7 \ g * 1[/tex]
[tex]14 \ g/cm^3 * v= 7 \ g[/tex]
Now the variable is being multiplied by 14 grams per cubic centimeters. The inverse operation of multiplication is division, so we divide both sides by 14 g/cm³.
[tex]\frac {14 \ g/cm^3 * v}{14 \ g/cm^3}= \frac {7 \ g }{14 \ g/cm^3}[/tex]
[tex]v= \frac {7 \ g }{14 \ g/cm^3}[/tex]
The units of grams cancel.
[tex]v= \frac {7 }{14 \ cm^3}[/tex]
[tex]v= \frac {1}{2} \ cm^3[/tex]
The volume of the solid is 1/2 or 0.5 cubic centimeters.
