How much salt is in the human body?​

Answer»

The human body contains many SALTS, of which sodium chloride (AKA common table salt) is the MAJOR one, MAKING up around 0.4 per CENT of the body's weight at a concentration pretty well equivalent to that in seawater. So a 50kg person would contain around 200g of sodium chloride – around 40 teaspoons.

Angle of incidence 15 degree into angle of reflection​

Answer» SINCE the angle between the mirror and the INCIDENT ray is 75 degrees, the angle of INCIDENCE (i.e., angle between the incident ray and the normal) will be 90–75=15 degrees. Now, from the laws of reflection, we know that angle of incidence is equal to angle of reflection. Therefore, angle of reflection is 15 degrees.

Write a short note of regeneration of reproduction in lower and higher animals chapter​

Answer»

your answer... In biology, regeneration is the process of renewal, restoration, and tissue growth that makes genomes, cells, organisms, and ecosystems resilient to natural fluctuations or events that cause disturbance or damage.[1] Every SPECIES is capable of regeneration, from bacteria to HUMANS.[2][3] Regeneration can either be complete[4] where the new tissue is the same as the lost tissue,[4] or incomplete[5] where after the NECROTIC tissue comes fibrosis. At its most elementary level, regeneration is mediated by the molecular processes of gene regulation and involves the cellular processes of cell proliferation, morphogenesis and cell differentiation.[6][7] Regeneration in biology, however, mainly refers to the morphogenic processes that characterize the phenotypic plasticity of traits allowing multi-cellular organisms to repair and MAINTAIN the integrity of their physiological and morphological states. Above the genetic level, regeneration is fundamentally regulated by asexual cellular processes.[8] Regeneration is different from reproduction. For example, hydra perform regeneration but reproduce by the method of budding. Hope it will be helpful for you. Thanks for reading. Mark as brainliest.

Write notes o > a) blood Lymph xylem phloem​

Answer»

Blood, fluid that transports oxygen and nutrients to the cells and carries away carbon dioxide and other waste products. Technically, blood is a transport liquid pumped by the heart (or an equivalent structure) to all parts of the body, after which it is returned to the heart to repeat the process.Lymph- a colourless liquid containing white blood cells that cleans the inside of your body and helps to prevent infections from spreadingxylem - Xylem, plant VASCULAR tissue that CONVEYS water and dissolved minerals from the roots to the rest of the plant and also provides physical support. Xylem tissue CONSISTS of a variety of specialized, water-conducting cells known as tracheary elements.phloem - Phloem is the living tissue in vascular plants that transports the soluble organic compounds made during PHOTOSYNTHESIS and known as photosynthates, in particular the SUGAR sucrose, to parts of the plant where needed. This transport process is called translocation. hope it helps!!!

What is the optimum temperature for catalyses?​

Answer»

For any chemical reaction, the reaction rate INCREASES with TEMPERATURE, so the HIGHER the temperature, the faster the rate. For any enzymatic reaction, the reaction rate will increase with temperature until the temperature at which the enzyme BEGINS to denature is reached, and this is the optimum temperature.The denaturizing temperature depends on the composition of the protein (its amino acid sequence), which varies for catalyses from different organisms. Therefore, the answer to your question is that the optimum temperature is dependent on the source organism.Download Biology PDF Read All 198 Biology Questions

AIM : To observe the cells. MATERIALS REQUIRED : Root, blade,petridish, water, slide, brush,stain,water glass, needle, covering glass, glycerine, tissue paper, microscope.PROCEDURE : Thin pieces of the cross section of root are taken from the water using the brush and transferred to the water in the watch glass.The thinner pieces are selected and transferred into another watch glass and added two drops of stain. After two minutes the excess stain from the cross section is washed away and then it is placed in the glycerine on the glass slide. The piece of cross section is closed air tight using cover glass. The excess glycerine is wiped out by the tissue paper and then the slide is placed on the stage of the microscope. Looking through the eyepiece the knob is turned slowly to get the clear image.OBSERVATIONS : We got an enlarged vision of different cells. When observed through 10x lenses he sew the full and enlarged cross section. When observed through 45x lens a part of the section is found much enlarged. We could not see the cross section completely.INFERENCE : The plant body is made up of different kinds of cells. When we 'x' increase the size of the image also increase.
