Starch is a carbohydrate which is a polysaccharide and not a simple sugar like glucose, fructose,etc.
A carbohydrate is defined as a bio-molecule which consists of carbon,hydrogen and oxygen atoms which are usually in the ratio of 2:1 with the empirical formula C(H₂O).
This term is most commonly used in biochemistry as a synonym of saccharide which is a group of sugars, starch and cellulose.
They perform various functions in living organisms. They serve as an energy source and as well as structural components . They are a key component in providing nutrition and are found in wide variety of natural as well as processed foods.
Carbohydrates occur as cellulose in the cell walls of plants and is one of the components of insoluble dietary fibers.

Answer: The mass of aluminium cylinder is 4065 kg.
Explanation:
Density is defined as the ratio of mass of the object and volume of the object.
Mathematically,
We are given:
Density of aluminium =
Volume of aluminium cylinder =
Putting values in above equation, we get:
Hence, the mass of aluminium cylinder is 4065 kg.
The mass of the compound can be calculated by the molarity. The mass of the calcium bromide in the given solution is 2.5 g.
The mass of the given compound can be calculated by the molarity formula,
Where,
M- molarity of the solution = 0.25 M
w - given mass =?
m -molar mass of Calcium bromide = 200 g/mol
v-volume in mL= 50 mL
Put the values in the formula,
Therefore, the mass of the calcium bromide in the given solution is 2.5 g.

Vegetation slows and prevents sediment loss in rivers and streams by binding the soil together and slowing down the flow of water. Shade from plants also helps reduce phytoplankton growth.
Vegetation plays a crucial role in slowing and preventing sediment loss in rivers and streams. The roots of plants help bind the soil together, reducing erosion caused by the force of water. As water flows through vegetation, it is slowed down, allowing sediment to settle out. Additionally, plants provide shade, which helps keep the water temperature lower, creating an environment less suitable for phytoplankton growth.

Magnetizing steel is a physical change, not a chemical change because it does not change the chemical composition of the steel.
A chemical change is a change in which new substances are formed. This is because the atoms in the original substances are rearranged to form new atoms or molecules. There is no chemical change when magnetizing steel. For example, when iron rusts, it reacts with oxygen to form a new substance called iron oxide.
A physical change is a change in which the form of a substance is changed, but the substanceitself is not changed. For example, when you melt ice, you are changing the form of water from a solid to a liquid, but the water itself is not changed.
When you magnetize steel, you are simply aligning the magnetic domains in the steel. Magnetic domains are regions of a material that have a net magnetic field. When the magnetic domains are aligned, the steel becomes magnetized.
Magnetizing steel does not change the chemical composition of the steel. The steel is still made up of the same atoms, and the atoms are still arranged in the same way. The only difference is that the magnetic domains are aligned, which gives the steel its magnetic properties.
