80/120 mm Hg.Normal blood pressure is considered to be at or below 120 over 80 (120/80). Normally, blood pressures are usually categorized into three groups: low (90/60 or lower), high (140/90 or higher), & normal (values above 90/60 & below 130/80).
Thigmotropism.Thigmonasty (thigmotropism) refers to plant movement in response to touch or physical contact without regard to the direction of the stimulus.) as a result of contact with an insect. Thigmonastic movements are exemplified by the closing of the insect-eating plant Venus's flytrap (Dionaea muscipula) & the bending of the glandular hairs of sundew (Drosera sp.
water.The source of oxygen produced during photosynthesis is the splitting of water molecule into hydrogen & oxygen. Although photosynthesis can happen in different ways in different species, some features are always the same. Photosynthesis uses carbon dioxide & water, releasing oxygen as a waste product. For example, the process always begins when energy from light is absorbed by proteins called photosynthetic reaction centers that contain chlorophylls. In plants, these proteins are held inside organelles called chloroplasts, while in bacteria they are embedded in the plasma membrane. Some of the light energy gathered by chlorophylls is stored in the form of adenosine triphosphate (ATP). The rest of the energy is used to remove electrons from a substance such as water. These electrons are then used in the reactions that turn carbon dioxide into
in the Brain.The pineal gland is a small endocrine gland in the vertebrate brain. Its shape resembles a tiny pine cone (so its name), & it is situated near the core of the brain. It produces the serotonin derivative melatonin, a hormone that affects the modulation of wake/sleep patterns & seasonal functions.
Penicilin.Penicillin is a group of antibiotics derived from Penicillium fungi. Penicillin antibiotics are historically significant as they are the 1st drugs that were effective against many previously serious diseases,such assyphilis, & infections caused by staphylococci & streptococci. They include penicillin G, procaine penicillin, benzathine penicillin, & penicillin V. Penicillins are still widely used today, though many types and categories of bacteria are now resistant. All penicillins are Ã¢-lactam antibiotics & are used in the treatment of bacterial infections caused by susceptible, usually Gram-positive, organisms.
fermentation.On industrial scale, ethanol can be prepared by the fermentation of molasses. It is a dark colored viscous liquid. Molasses is the mother liquor left after the crystallization of sugarcane juice. Molasses contains about 60% fermentable sugar.
Photosynthesis.Plants reduce the CO2, as they use it with photosynthesis. It is for this reason that plantation of trees has been stressed by environmentalists. They use it to give oxygen & carbohydrates as the final product.
D. it has the water sac in the walls of the lumen of stomach
Answer & Explanation
Answer : Option
Camels, in ideal conditions, can go 6-7 months without water but as the temperature rises they have to drink water more often. Camels are well known for their humps. They do not, however, literally store water in them as is commonly believed, though they do serve this purpose through roundabout means. Their humps are a reservoir of fatty tissue, while water is stored in their blood. However, when this tissue is metabolised, it is not only a source of energy, but yields through reaction with oxygen from the air 1111 g of water per 1000 g of fat. This allows them to survive without water for about two weeks, & without food for up to a month. Camels are able to withstand changes in body temperature & water consumption that would kill most otheranimals. Their temperature ranges from 34 Â°C at night & up to 40 Â°C during the day. Camels rarely sweat, even when ambient temperatures reach 49 Â°C. Any sweat that does occur evaporates at the skin level rather than at the surface of their coat, & the heat of vaporization so comes from body heat rather than ambient heat. Camels can withstand losing 25% of their body weight to sweating (most mammals can withstand only about 12â€“14% dehydration before cardiac failure results from circulatory disturbance). A feature of their nostrils is big amounts of water vapor in their exhalations is trapped & returned to their body fluids, thereby reducing the amount of water lost through respiration. The kidneys & intestines of a camel are very efficient at retaining water.
