Prompt
Explain how scientific theories differ from scientific laws.

Answers

Answer 1

Answer:

Some scientists will tell you that the difference between them is that a law describes what nature does under certain conditions, and will predict what will happen as long as those conditions are met. A theory explains how nature works.

Describe the difference in how a monosaccharide and polysaccharide are digested

Answers

Answer:

polysaccharides from cells walls make up the fiber humans eat, while monosaccharides provide the sweetness in food. As humans eat, chewing breaks down polysaccharides into smaller particles that eventually, through digestion, yield up the simple monosaccharides that can pass into the bloodstream

The monosaccharide provide longer storage and structural stability as humans eat chewing breaks down polysaccharide into smaller particles that go through digestion eventually, monosaccharide that goes into the bloodstreams

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.

Answers

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

ANSWER FAST PLEASE According to Dalton’s theory, why are carbon and oxygen differ.ent elements?

Answers

Carbon atoms have 6 protons while oxygen only has 8. Oxygen has more mass then a carbon atom since it has more protons and neutrons :)

According to the Dalton's theory, carbon and oxygen are different elements because they are made up of different atoms which have different numbers of proton and neutrons.

What is Dalton's theory?

John Dalton proposed his modern theory of atoms in 1803. He discovered atom, which is the smallest unit of particle. This theory is also known as the atomic theory of matter.

In this theory, he stated that every single atom of an element, such as sodium, is same as the other atoms of the same element. He also stated that the atoms of one element differ from the atoms of other elements. This theory is mostly found to be true. For example: A sodium atom is different from a carbon atom.

However, his theory was found to be found as the atoms present in the elements are found to be divisible into even smaller particles like protons, neutrons, and electrons.

how does the concentration of electrolytes in and outside a cell control the movement of water

Answers

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

can anybody help me with this?

Answers

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
