Myopia also is known as short-sightedness, while Hyperopia is also known as long-sightedness. These are the defects of vision of an eye in which a person is unable to see the near by or distant objects. The condition in which the person is not able to see the distant object is known as myopia or short-sightedness. Although long-sightedness is opposite to that of earlier given condition, as in this the person is not able to the nearby objects. There are other vision problems also like … [Read more...]

When one allele for a specific trait does not completely dominate over the other allele, and therefore the phenotype produced is the complete mixture of both dominant and recessive allele is known as Incomplete Dominance. While in Co-Dominance both the allele for a specific trait are equally expressed. The resultant phenotype will express both the character equally of both participating alleles. As stated by Gregor Mendel, traits are inherited by the transfer of genes from parents to their … [Read more...]

Saturated fatty acids do not contain double bonds C-C (only single bonds), whereas unsaturated fatty acids contain one or more double bonds C=C. The chain length of most common fatty acids is of 16-18 number of carbon. The triglyceride is considered as the common and simple type of fat, having three fatty acids and glyceride. By the chemical structure of fatty acid chain, the division is done. Fatty acids are the carboxylic acids with the side chain of hydrocarbon and also the simplest form … [Read more...]

Cilia are short, hair-like structure, present in large numbers in a cell, while flagella are long, hair-like complex structure and are few per cell. Cilia and flagella are hair-like appendages, extending through the surface of the living cell, they differ in their mode of beating, size, and number. Cilia and flagella are the locomotory structure, which is the extension of the plasma membrane of the cell. Besides the locomotion, they also help in other processes like respiration, excretion, … [Read more...]

The respiratory disease which is diagnosed during childhood, resulting in shortness of breathing, dryness of a cough, chest tightening is called asthma. On the other hand, COPD also known as Chronic Obstructive Pulmonary Disease is also one of the respiratory disease, which occurs after the age of 4o, and the condition gets progressively worse with age. The cell's of our body need oxygen to work and grow, and this oxygen is taken by the lungs through the simple process of breathing. Usually, … [Read more...]

The significant difference between these two is that the nervous system uses electrical signals or impulses to send the signals through neurons, while the Endocrine system uses hormones acting as the chemical messenger to send signals to the target cell through the blood stream in the body. However, both are the regulatory system allows the communication between the tissue, organs, and cells. These systems have the responsibility to control and coordinate the signals given to the body, … [Read more...]

Plasma is that part of the blood, which contains blood clotting agent called as fibrinogen, while serum is the fluid part of the blood and does not contain clotting agent. The plasma and serum can be extracted from the centrifugation of blood. The serum is obtained after the clotting of blood, while plasma can be obtained before the coagulation of the blood. Centrifugation separates the blood components by its weight, size, and density. The fluid circulating in the body through arteries and … [Read more...]

Nature and the cause are the main difference between the osteoarthritis and rheumatoid arthritis. Osteoarthritis is the kind of degenerative condition, while rheumatoid arthritis is a kind of autoimmune disease, where the body itself attacks the body's joints. Osteoarthritis is due to the increased wear and tear on joints, whereas rheumatoid arthritis produces the inflammation of the joints throughout the body, also resulting in fever and severe fatigue. There are many forms of arthritis like … [Read more...]

The major difference between heterochromatin and euchromatin is that heterochromatin is such part of the chromosomes, which is a firmly packed form and are genetically inactive, while euchromatin is an uncoiled (loosely) packed form of chromatin and are genetically active. When the non-dividing cells of the nucleus were observed under the light microscope, it exhibited the two regions, on the ground of concentration or intensity of staining. The dark stained areas are said as heterochromatin … [Read more...]
