Aerobic denotes the term 'in the presence of oxygen' while the word anaerobic denotes the 'absence of oxygen'. So the respiration which occurs in the presence of oxygen is called as aerobic respiration, on the other hand, respiration occurring in the absence of oxygen is known anaerobic respiration. So accordingly the chemical reaction involving the breakdown of the nutrient molecule with the aim of producing energy is called respiration. Thus the energy required by the body to perform well … [Read more...]
Difference Between Osmosis and Diffusion
Osmosis and Diffusion both depict the movement of particles from higher concentration to lower concentration. However, osmosis is a type of diffusion that is limited to fluids. Whereas, diffusion is not restricted and is prevalent in solids, liquids and gases. The passage of the solvent molecules in osmosis occurs through a selectively permeable membrane. In contrast, for diffusion, the membrane is not mandatory. It can spread the particles directly within the given medium. Osmosis … [Read more...]
Difference Between Abiotic and Biotic Factors
We can divide the ecosystem into two main categories: abiotic and biotic, based on whether they are living or non-living. Our ecosystem acts as a platform that portrays the interaction between the biotic and abiotic factors. The biotic factors include the living components that can grow, survive and adapt. Whereas the abiotic factors are simply the non-living elements of the environment. They tend to impact the rate of growth, survival and adaptation of the biotic components. Thus, you can … [Read more...]
Difference Between Heterochromatin and Euchromatin
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...]
Difference Between Bones and Cartilage
Both bones and cartilages are connective tissues. But they vary in their structures and functions. Bones on one hand are harder, solid and rigid structures. Their primary function is to provide structure and stability to the body. They also protect the internal organs from getting injured. While the cartilages are soft and flexible tissues. They are present between two bones to support joints. Also, they reduce the impact of friction while moving. The cells of bones are osteocytes and … [Read more...]
Difference Between Hepatitis and Jaundice
Hepatitis is said to be the inflammation of the liver cells due to the attack of virus, bacteria, parasites, drugs, ischemia, toxins, etc. On the other hand, when there is surplus deposition of the bile pigment in blood especially of bilirubin, resulting in the yellow discoloration of the eye (sclera), skin, it is called as Jaundice. Hepatitis is the liver disease, while jaundice is a sign of the increased production of a yellow pigment called bilirubin in the blood. Hepatitis and jaundice … [Read more...]
Difference Between Pollination and Fertilization
Pollination is a process of transferring of pollens from one flower to another. While fertilization is the process after the successful transfer of pollination, which involves the fusion of male gametes and female gametes of plants. Both of these are the natural process. But only flowering plants undergo the process of pollination, while fertilization is the common process of almost all living being. Continuation of life would not have been possible without the presence of plants, as directly … [Read more...]
Difference Between Inhalation and Exhalation
The inhalation and exhalation are the two basic mechanisms involved in the process of breathing. These processes facilitate the exchange of oxygen and carbon dioxide. During the process of inhalation, the diaphragm contracts and moves in a downward direction. And the ribs move outwards and upwards. These movements cause an increase in the intrapulmonary volume and the expansion of the thoracic cavity. As the volume inside increases, the intrapulmonary pressure falls down. So, in order to … [Read more...]
Difference Between Hypothyroid and Hyperthyroid
The condition when the thyroid gland produces less amount of thyroid hormones is called hypothyroid, while the condition when there is the overproduction of hormones by the thyroid gland is called hyperthyroid. The thyroid gland is located in a front portion of the neck and affects almost whole body's metabolic process. The main function of thyroid gland is to store, secrete, and produce hormones especially triiodothyronine (T3) and thyroxine (T4) into the bloodstream that regulates numerous … [Read more...]
Difference Between Phytoplankton and Zooplankton
The basic difference between phytoplankton and zooplankton is that the word 'phyto' is used for the small plants like diatoms and algae and word 'zoo' is used for the small animals like tiny fish, crustaceans, which are the weak swimmers and just move along the currents. The word "plankton" refers to the smallest aquatic plants or animals that float and drift in the limnetic zone of water bodies. Planktons are divided into two categories where one is called as permanent plankton and the other … [Read more...]
