Explanation:

Unlike Eukaryotic cells, PROKARYOTES have no nuclear membrane. Instead, their genetic material (DNA) EXISTS as a naked, tightly coiled clump in the cytoplasm of the cell. While they can vary greatly in length, plasmids are typically from 103 to 105 base pairs of DNA LONG.

Answer:

hi dear,

(iii) The DIFFERENCE between passive transport and ACTIVE transport is that the active transport requires energy, and moves substances against their respective concentration GRADIENT, WHEREAS passive transport requires no cellular energy and moves substances in the DIRECTION of their respective concentration gradient.

Answer:

The role of osmosis is twofold – it helps maintain a stable INTERNAL environment in a living organism by keeping the pressure of the inter and intra-cellular FLUIDS balanced, and it allows the ABSORPTION of nutrients and expulsion of waste from various bodily organs on the cellular level.

Answer:

When a stimulus is detected by a sensory receptor, it can elicit a reflex via stimulus transduction. An internal stimulus is often the first component of a HOMEOSTATIC CONTROL system. ... Although stimuli commonly cause the BODY to respond, it is the CNS that finally DETERMINES whether a signal causes a reaction or not

Answer:

In classical mechanics, Newton's laws of motion are THREE laws that describe the relationship between the motion of an OBJECT and the forces ACTING on it. The FIRST law states that an object either remains at rest or continues to move at a constant velocity, unless it is acted upon by an external force

Answer:

The brain is a soft and DELICATE ORGAN. A hard blow to the head can injure the brain or spinal cord even when there are no visible signs of trauma to the scalp or face. That's why all head INJURIES are considered serious and should be assessed by your DOCTOR or the nearest hospital EMERGENCY department.

Explanation:

Eyepiece: The lens the viewer looks through to see the specimen. The eyepiece usually CONTAINS a 10X or 15X power lens.

Diopter Adjustment: Useful as a means to change focus on ONE eyepiece so as to CORRECT for any difference in vision between your two eyes.

Body tube (Head): The body tube connects the eyepiece to the objective lenses.

Arm: The arm connects the body tube to the base of the microscope.

Coarse adjustment: BRINGS the specimen into general focus.

FINE adjustment: Fine tunes the focus and increases the detail of the specimen.

Nosepiece: A rotating turret that houses the objective lenses. The viewer spins the nosepiece to select different objective lenses.

Explanation:

Biogas, naturally occurring gas that is generated by the breakdown of organic matter by anaerobic bacteria and is used in energy production. Biogas differs from natural gas in that it is a renewable energy source produced biologically through anaerobic digestion rather than a fossil fuel produced by geological processes. Biogas is primarily COMPOSED of methane gas, carbon dioxide, and trace amounts of nitrogen, hydrogen, and carbon monoxide. It occurs naturally in compost heaps, as swamp gas, and as a result of enteric fermentation in cattle and other ruminants. Biogas can also be produced in anaerobic digesters from plant or animal waste or collected from landfills. It is burned to generate heat or used in combustion engines to produce electricity.

The use of biogas is a green technology with environmental benefits. Biogas technology enables the effective use of accumulated animal waste from food production and of municipal solid waste from urbanization. The conversion of organic waste into biogas reduces production of the greenhouse gas methane, as efficient combustion replaces methane with carbon dioxide. Given that methane is nearly 21 times more effective in trapping heat in the atmosphere than carbon dioxide, biogas combustion results in a net reduction in greenhouse gas emissions. Additionally, biogas production on farms can reduce the odours, insects, and pathogens associated with traditional manure stockpiles.

Animal and plant wastes can be used to produce biogas. They are processed in anaerobic digesters as a liquid or as a slurry mixed with water. Anaerobic digesters are generally composed of a feedstock source holder, a digestion tank, a biogas recovery unit, and heat exchangers to maintain the temperature necessary for bacterial digestion. Small-scale household digesters containing as little as 757 litres (200 gallons) can be used to PROVIDE cooking fuel or electric lighting in rural homes. Millions of homes in less-developed regions, including China and parts of Africa, are estimated to use household digesters as a renewable energy source.

Large-scale farm digesters store liquid or slurried manure from farm animals. The primary types of farm digesters are covered lagoon digesters, complete mix digesters for slurry manure, plug-flow digesters for dairy manure, and dry digesters for slurry manure and crop residues. Heat is usually required in digesters to maintain a constant temperature of about 35 °C (95 °F) for bacteria to decompose the organic material into gas. An efficient digester may produce 200–400 cubic metres (7,000–14,000 cubic feet) of biogas containing 50–75 percent methane per dry ton of INPUT waste.

The natural decomposition of organic matter in a landfill occurs over many YEARS, and the biogas produced (also known as landfill gas) can be collected from a series of interconnected pipes located at various depths across the landfill. The composition of this gas changes over the life span of the landfill. Generally, after one year, the gas is composed of about 60 percent methane and 40 percent carbon dioxide. Landfill collection varies according to the percentage of organic waste and the age of the facility, the average energy potential being about 2 gigajoules (1,895,634 BTU) per ton of waste.

Landfill gas collection systems are increasingly being implemented to prevent explosions from methane accumulation inside the landfill or to prevent the loss of methane, a greenhouse gas, into the atmosphere. The collected gas can be burned at or near the site in furnaces or boilers, but it is instead often used in internal combustion engines or gas turbines to create electricity, given the limited need for heat production at most remote landfill locations.

Answer:

DETRITIVORES are organisms that FEED on the ORGANIC waste of DEAD plants and animals while decomposers are the organisms that DECOMPOSE dead plants and animals.

Explanation:

(a)

Aerobic Respiration ANAEROBIC Respiration

1. Aerobic respiration takes place in the presence of free oxygen. 1. Anaerobic respiration takes place in the absence of free oxygen.

2. The first STEP of this process (glycolysis) takes place in the cytoplasm while the second step (Krebs cycle) is carried out in mitochondria. 2.The complete process is carried out outside the mitochondria i.e., in the cytoplasm.

3. Glucose is completely oxidized into carbon dioxide and water. 3. Glucose is incompletely oxidized into carbon dioxide and ethyl alcohol.

4. 38 molecules of ATP are produced by the complete oxidation of one gram-mole of glucose. 4. Only 2 molecules of ATP are formed in this process.

(b)

Glycolysis

Fermentation

1. Glycolysis is a common process during aerobic and anaerobic respiration. 1. Fermentation is a type of anaerobic respiration.

2. PYRUVIC acid is produced as its end product. 2. Ethanol or lactic acid is produced as its end product.

(c)

Glycolysis Citric acid cycle (Krebs cycle)

1. It is a LINEAR PATHWAY. 1. It is a cyclic pathway.

2. It occurs in the cell cytoplasm. 2. It occurs in the mitochondrial matrix.

3. It occurs in both aerobic as well as in anaerobic respiration. 3. It occurs in aerobic respiration only.

4. One glucose molecule breaks down to generate 2 NADH22 and 2 ATP molecules. 4. It produces 6 NADH22, 2 FADH22, and 2 ATP molecules on the breakdown of two acetyl-CoA molecules generated after glycolysis.

Answer:

Plastic containers are favoured for storing food DUE to the following reasons :

Plastic containers are lightweight. They do not REACT with the food ITEMS and so safer to store unlike ALUMINIUM which reacts with lemon PICKLES. It has good strength,durability and quality.

Chemical METHODS include ion exchange, PRECIPITATION, oxidation and REDUCTION, and neutralization. Among thermal methods is high-temperature INCINERATION, which not only can detoxify certain organic wastes but also can DESTROY them.

Answer:

If water is consumed after taking these FRUITS, it can UPSET your digestion. This is because water CONTAINING food smoothens the digestion process and makes the BOWEL movement easy. If water is consumed over them, the bowel movement becomes too smooth and can LEAD to loose motion/diarrhoea
