Explanation

The most abundant carbohydrate in nature is cellulose

It is a structural polysaccharide that forms the cell walls of plants and is found in vast quantities throughout the plant kingdom. 

Explanation

The salt content in seawater is mainly due to the presence of sodium chloride i.e sodium and chlorine. The abundant element in  seawater is chloride, which accounts for 1.94% of  the total composition. 

 Chloride is followed by 1.08% sodium, 0.04% potassium  and a small amount of iodine.

Explanation

Concrete drying is a continuous and fluid event, and usually reaches its full effective strength after about 28 days.

Explanation

Answer:

A

The feature of the dynamo is to alternate mechanical strength into electricity. The managed equipment related to the dynamo regulates the modern output in step with the needs of the electrical device and the country of the battery.

Explanation

Explanation

In a solid state, particles cannot move from their position.

They can only vibrate at their mean position.

 The particles in solids vibrate about fixed positions; even at very low temperatures.

Answer:

B

There are two ways to freeze and store sperm: dry ice and alcohol (100 degrees Fahrenheit) and liquid nitrogen (320 degrees Fahrenheit). Liquid nitrogen is preferred because there is no evidence that fertility declines with age. Sperm stored in dry ice alcohol will gradually reduce their chances of giving birth.

Explanation

Answer:

Radionuclides (or radioactive substances) are a type of chemical substance whose atomic nucleus is unstable. They achieve stability through nuclear fission (spontaneous fission, emission of alpha particles, or conversion of neutrons to protons, or vice versa).

Explanation

The admixtures slow down the initial rate of hydration of cement or prolong the setting of cement paste in concrete.

Retarding admixtures are frequently required in hot weather conditions to facilitate delaying the setting time

Explanation

• A voltaic cell is an electrochemical cell that makes use of a chemical reaction to supply electrical energy. Zinc is used as anode and copper is used as cathode.
• The voltaic cell makes use of  extraordinary metal electrodes, each in an electrolyte answer. The anode will go through oxidation and the cathode will undergo reduction. The steel of the anode will oxidize, going from an oxidation kingdom of zero (in the solid form) to a positive oxidation nation, and it becomes an ion. at the cathode, the steel ion within the answer will accept one or extra electrons from the cathode, and the ion’s oxidation kingdom will lessen to 0.
• This paperwork a strong steel that deposits on the cathode. the two electrodes ought to be electrically linked to each different, taking into consideration a go with the flow of electrons that depart the metal of the anode and glide thru this connection to the ions on the surface of the cathode. This float of electrons is an electrical modern-day that can be used to do work, inclusive of flip a motor or electricity a mild.
