What is RNA virus?Deoxyribose and ribose, respectively, are the names of the pentose sugars found in DNA and RNA. The presence of the hydroxyl group on the 2' carbon of ribose and its lack on the 2' carbon of deoxyribose distinguishes the sugars.While the sugar used to construct both DNA and RNA is named deoxyribose (left in the image), the sugar used to construct RNA is simply referred to as ribose.Ribose, a 5-carbon sugar, is present in RNA, whereas deoxyribose, a 5-carbon sugar, is present in DNA. Both kinds of sugar are crucial parts of nucleotides. Pentose sugars, which are a component of DNA, can be found in nucleic acid.

A and B are linked genes. In a study of 100 offspring, 94 had parental genotypes for A and B, while 6 were recombinants. A and B are _____ centimorgans (cM) apart
A and B are linked genes. In a study of 100 offspring, 94 had parental genotypes for A and B, while 6 were recombinants. A and B are 6 centimorgans (cm) apart.
Genes that are physically adjacent to one another on the same chromosome are said to be linked genes because they are more likely to be inherited together. Chromosomes are recombined during meiosis, causing gene swaps between homologous chromosomes. Together, they are inherited. For instance, certain eye and hair colors are inherited jointly and are related genetically.By dividing the total number of recombinant gametes by the total number of gametes, X 100 the linkage distance is determined.Thus here the total recombinant genes are 6 and the total number of gametes or offspring are 100 so,
[(6/100) x 100]
= 0.06 x 100
= 6
Hence, A and B are 6 cm apart.

Thyroid gland
Our body turns the food and liquid you consume into energy through a process known as metabolism. This intricate process releases the energy your body requires to function by combining calories from food and beverages with oxygen.
Anabolism is the process of constructing new body tissues and energy reserves, while catabolism refers to the process of destroying existing body structures and energy reserves to get additional fuel for bodily operations (called catabolism). The thyroid gland produces and secretes a hormone that is crucial in controlling how quickly or slowly the body's chemical reactions for metabolism move. A crucial hormone gland, the thyroid gland is important for the growth, development, and metabolism of the human body.

Briefly define osmosis and diffusion, being sure to explain how they are different and how they are similar?
Osmosis is the process by which solvent particles flow from a dilute solution to one that is more concentrated. Diffusion, in contrast, is the transfer of particles from a region of higher concentration to one of lower concentration.
What are the differences and similarities between osmosis and diffusion?Differences:
While osmosis describes the process by which water, or other solvents, flow through a semipermeable membrane, leaving other bits of matter in its path, diffusion involves molecules in a high concentration area moving to areas with a low concentration. As an illustration, oxygen diffuses into red blood cells, and salt placed outside a cell would osmotically suck the water out of the cell, drying it.Molecular size and electric charge affect how quickly molecules diffuse through a membrane.

Advances in Epidural Spinal Cord Stimulation to Restore Function after Spinal Cord Injury: History and Systematic Review.
Spinal cord stimulation (SCS), and more especially epidural SCS (eSCS), was first created to treat chronic pain and has been described since 1967. It includes the surgical insertion of a tiny array of electrodes into the epidural region.
Abstract:Recent research has identified epidural spinal cord stimulation (eSCS) as a viable treatment for chronic spinal cord damage (SCI). It has been demonstrated that eSCS can find undiscovered routes in the injured spinal cord. The main conclusions that have been drawn so far about the application of eSCS in SCI are summarized in this review. Utilizing the reference lists from the included papers as well as the databases MEDLINE, EMBASE, and Web of Science, searches were conducted. Studies looking into the application of eSCS to enable volitional movement and to reestablish autonomic function in SCI patients were found using a combination of medical subject heading terms and keywords.

It was first recognized that miRNAs suppress gene expression at both the mRNA stability level by conducting mRNA degradation and the translation level (at initiation and after initiation) by inhibiting protein translation or degrading polypeptides by binding complementarily to the 3'UTR of the target mRNAs.
