    After a rose (Rosa spp.) is pollinated, the petals drop off to reveal the rose fruit, which is called a hip. Rose hips are actually seed pods, and each one contains dozens of seeds. Although you can grow roses from seeds, most are hybrids, so the results are unpredictable. Rose Apples are not apples; they are another fruit altogether that grow in the tropics. ... Other times the fruit will be more pear or bell-shaped, or a pink or reddish skin, particularly Malaysian varieties. The white flesh inside is crisp, faintly sweet and fragrant.

    The mechanism of hearing. Sound waves enter the outer ear and travel through the external auditory canal until they reach the tympanic membrane, causing the membrane and the attached chain of auditory ossicles to vibrate. Sound transfers into the ear canal and causes the eardrum to move. The eardrum will vibrate with vibrates with the different sounds. These sound vibrations make their way through the ossicles to the cochlea. Sound vibrations make the fluid in the cochlea travel like ocean waves.

    A countercurrent mechanism system is a mechanism that expends energy to create a concentration gradient. ... For example, it can refer to the process that is underlying the process of urine concentration, that is, the production of hyperosmotic urine by the mammalian kidney. The counter-current multiplier or the countercurrent mechanism is used to concentrate urine in the kidneys by the nephrons of the human excretory system. The nephrons involved in the formation of concentrated urine extend all the way from the cortex of the kidney to the medulla and are accompanied by vasa recta.

    Epithelial tissues are thin tissues that cover all the exposed surfaces of the body. They form the external skin, the inner lining of the mouth, digestive tract, secretory glands, the lining of hollow parts of every organ such as the heart, lungs, eyes, ears, the urogenital tract, as well as the ventricular system of the brain and central canals of the spinal cord.

    The main functions of simple epithelial tissues are:

    (i) The cells form the outer layer of skin. They protect the underlying cells from drying, injury, infection and chemical effects.

    (ii) They regulate the exchange of materials between the body and the external environment. 

    (iii) They help in absorption of water and other nutrients, especially in alimentary canal.

    (iv) They help in the elimination of waste products.

    (v) Some of them are greatly specialized (glandular cells) and perform secretory function.

    Transaminases or aminotransferases are enzymes that catalyze a transamination reaction between an amino acid and an α-keto acid. They are important in the synthesis of amino acids, which form proteins. The liver has transaminases to synthesize and break down amino acids and to convert energy storage molecules. The concentrations of these transaminases in the serum (the non-cellular portion of blood) are normally low. Transaminitis, sometimes called hypertransaminasemia, refers to having high levels of certain liver enzymes called transaminases. When you have too many enzymes in your liver, they start to move into your blood stream.

    Photorespiration is the phenomenon only in C3 plants where RUBP combines with oxygen tl form phosphoglycerate aling with the main product that is phosphoglyceric acid.the formation of phosphoglycerate decreases the amount of PGA.its a totally wasteful process because nothing is formed and even 1 atp is utilized. C4 plants have an inbuilt machenism to control this.also there is much CO2 concentration in the intercellular spacea which prevents the RUBO in bundle sheat cells to form any other product other than PGA

    The increase in CO2 ensures that the enzyme RuBisCo does not act as an oxygenase, but as a carboxylase. This prevents photorespiration and increases the rate of photosynthesis. Thus, C4 plants are highly productive.The enzyme RuBisCo is absent from the mesophyll cells of C4 plants.
