Answer:
<h2>
Protein exists in different forms- primary, secondary, tertiary and quaternary structure.</h2>
Explanation:
Primary structure of protein consists of amino acids joined by a peptide bonds. Peptide bond exists as covalent bond. Secondary structure of protein is stabilized by hydrogen bonds. Tertiary structure is stabilized by hydrophobic interaction, electrostatic interaction and disulphide bonds. Similarly, quaternary structure is stabilized by non-covalent interactions and disulphide bonds. So, each structure of protein is stabilized by different types of bonds.
Answer: diastema
Explanation:
Diastema is condition in which a gap develops in between the two teeth. The spaces or gaps develop in the upper front teeth. The space or gap may appear between the biting teeth (canines or incisors) and in between the grinding teeth (molars or premolars). This occurs when there is unequal relationship develop between the size of jaw and teeth. The space can be too large that it can accommodate the parts of lower canine.
According to the above description, the condition can be considered as diastema.
Answer: A. Nitrogen
Explanation: Nucleic acids contain the same elements as proteins: carbon, hydrogen, oxygen, nitrogen; plus phosphorous (C, H, O, N, and P). Nucleic acids are very large macromolecules composed of repetitive units of the same building blocks, nucleotides, similar to a pearl necklace made of many pearls.
The answer is: sustained (or extended) release preparation.
<span>A sustained-release medication is a drug whose release of the active ingredient is controlled over time, that is to say, that it diffuses more slowly and longer in the body.
</span>These medications can be any type of preparation, it could be tablets, capsules, ophthalmic or dermal insert, suppository...
These biomoleules are found in following cellular structures.
<span>Carbohydrates- Cell wall, Golgi apparatus </span>
<span>Proteins- Plasma membrane, Endoplasmic reticulum, nucleus, cytoplasm, mitochondria, chloroplast etc. </span>
<span>Lipid- Plasma membrane, cytoplasm </span>
<span>Nucleic acid- Nucleus, chromosomes, mitochondria, chloroplast, ribosomes.</span>
