Answer:
Rough endoplasmic reticulum and Mitochondria.
Explanation:
Disulfide bonds are known as covalent bonds. They are formed by the oxidation of 2 cysteines and these bonds can provide stability to proteins. These bonds mainly formed in intermembrane space of mitochondria and cellular compartments outside the cytoplasm endoplasmic reticulum. Both of these organelles present in an oxidation state providing an atmosphere for disulfide bond formation.
Cytoplasm and Nuclei mostly exit in reducing state because of the existence of disulfide reductase which is reducing the disulfide bonds between the cysteine residue to thiolate state. So, the disulfide bond formation will not happen.
Answer:
The function of biomolecule inside our body system fully depends on the structure of that biomolecule.It is because the functional groups that participate in a chemical or biochemical reactions are arranged in a specific array in the structure of that biomolecule or macromolecule.
Explanation:
a enzyme structure/catalysis Enzymes are proteinecious in nature.Enzyme contain various amino acids in its active site such as histidine,serine,glutamic acid etc The amino acids of the active site of that enzyme interact with the substrate resulting in the formation of the product.
b mRNA structure/protein synthesis mRNA or messenger RNA consist of nucleotide sequence.The 3 concequetive nucleotides of an mRNA is termed as codons.Each codon codes for specific amino acid.The so formed amino acid linked with the adjacent amino acid by peptide linkage.
c cell membrane structure and signal transduction cell membrane contain various surface protein that act as receptor to detect signals by binding with signaling molecule during signal transduction process.

The correct answer is - They supply the energy needed for living processes.
Both the carbon and the nitrogen, are gases that are crucial for the survival of the organisms on the planet. They are mostly used by the producers in the ecosystems, as they need them to manage to perform their cycles, get nutrition, and of course energy. The producers are the basis of the ecosystems, so if they do not have a healthy supply of carbon and nitrogen, the ecosystems on the whole planet will collapse. The carbon and the nitrogen later go from one organism to another as the energy is transferred, and usually end up back into the atmosphere again.
Answer:
Medulla.
By analyzing the DNA extracted from the hair follicle, the medullary index and the pattern of medulla in the hair samples obtained from a crime scene, an investigator can identify the owner.
Explanation:
The hair consists of follicle and shaft. The follicle is the part of the skin, where the hair grows and the hair shaft has three layers: an inner medulla, a cortex, and an outer cuticle.
The morphology (physical characteristics) of hair provides a broad detail on the racial background of an individual and an investigator can identify a group of people who share similar traits. But the hair without follicle cells attached to it, cannot be used to identify a specific individual. If the follicle of a hair is present, then it can lead to individual identification by DNA analysis. Also the medulla of animals is larger than that in the humans. By comparing the medullary index (the ratio of the diameter of the medulla to the diameter of the entire hair), it can be determined if the hair obtained from crime scene belongs to animals or humans. The macroscopic (length, color, and curliness) and microscopic characteristics ( pattern of the medulla, pigmentation of the cortex, and types of scales on the cuticle) of the hair samples are studied during a crime investigation. If the entire hair follicle (follicular tag) is present in the hair samples found at the crime scene, the blood and tissue attached to the follicle is extracted and analyzed using DNA profiling. DNA analysis of the hair follicle provides an identification with greater accuracy than the hair shaft.
