Answer:

A) provide energy for cellular work

Explanation:

The Adenosine triphosphate (ATP) molecule is the nucleotide known in biochemistry as the "molecular currency" of intracellular energy transfer; that is, ATP is able to store and transport chemical energy within cells. ATP also plays an important role in the synthesis of nucleic acids.

ATP always GIVES ENERGY

Final answer:

The primary function of ATP is to provide energy for cellular work. It does so by transferring a phosphate group to a molecule and forming ADP. This key process drives cellular metabolism and enables life-critical activities.

Explanation:

The key role of ATP, also known as Adenosine Triphosphate, is to provide energy for cellular work. ATP carries out this function by transferring a phosphate group to a molecule. This breaks a high energy bond and forms ADP (Adenosine Diphosphate), releasing energy that can be utilized by the cell to do work.

ATP acts as the primary energy currency of the cell. This process is at the heart of cellular metabolism and is common to all living organisms. Essentially, ATP acts as a bridge, transferring energy from chemical reactions that yield energy to cellular processes that consume energy, such as muscular contraction, cell division, or the synthesis of biomolecules.

This is a "Exothermic Reaction."

I did the same test and this was the correct answer.

I hope this helps!

Answer:

(A.) three dimensional folded structure of the protein

Explanation:

The secondary structure of a protein is a regular structure built from interactions between neighboring amino acids as the polypeptide starts to fold or coil into its functional three-dimensional shape.

The two kinds of secondary structures arising from this polypeptide 'flexing' are either the  α-helix and β-pleated structures, all of which are vital to globular and fibrous proteins.

Final answer:

The secondary structure of a protein is the initial folding of the amino acid chain into a corkscrew-like shape (alpha helix) or a zigzag folding pattern (beta-pleated sheet). This occurs due to hydrogen bonding between the peptide bonds.

Explanation:

The secondary structure of a protein refers to the sense in which the polypeptide chain (the linear assembly of amino acids) begins to fold. This folding occurs due to the formation of hydrogen bonds between the peptide bonds in the chain. The two most common types of secondary structures are alpha helix (corkscrew-like shape) and beta-pleated sheet (zigzag folding pattern). Therefore, the correct answer to your question is option d: the twisting of the amino acid chain into a corkscrew-like shape or into a zigzag folding pattern.

Answer:

B absorption

Explanation:

because absorption is the transfer of energy carried by light waves to particles of matter

Answer: Option (A) is the correct answer.

Explanation:

An urban area is an area which is developed and it is a place where people can get almost all the things of their need easily.

Therefore, more an more people would like to live in an urban area as there will be more resources which can make people's work easy.

Hence, we can conclude that out of the given options an urban area is characterized by a dense human population.

Answer: The nucleus of radium-226 is unstable and hence undergoes decay.

Explanation: Radium has many isotopes. One of them is which has 88 protons and 138 neutrons. It is a radioactive isotope and undergoes decay process.

This isotope undergoes alpha - decay and produces Radon-222 isotope.

Equation for alpha - decay follows:

Hence, the nucleus of radium-226 undergoes decay process.
