Anerobic recporation1-:-In thos ptocess the bteakdown of food takes place in the presence of oxugen .

Piyush Thakur 6 years, 4 months ago

When the breakdown of glucose occurs with the use of oxygen, it is called aerobic respiration. Food can also be broken down , without using oxygen .This is called anaerobic respiration.

.. ... 6 years, 4 months ago

Anaerobic respiration:- -It takes place in absence of oxygen. -It involves incomplete oxidation of glucose to produce either Ethyl alcohol, CO2,energy or Lactic acid. -Very less amount of energy(2 ATP molecules). -It occurs in lower groups of organisms like bacteria,yeast,and some times in human muscles when they do rigrous exercises. -1)C6H12O6----------->2C2H5OH+2CO2+2ATP Glucose------------>Ethyl alcohol+carbon dioxide+energy 2)C6H12O6-------------->2C3H6O3+2ATP Glucose---------->Lactic acid+Energy

.. ... 6 years, 4 months ago

The similarities between aerobic and anaerobic respiration, is that they both use glucose as the starting molecule. This is called the substrate. In addition, both aerobic and anaerobic respiration produce ATP. ---------------------- i) Aerobic respiration:- -It takes place in presence of oxygen. -It involves complete oxidation of glucose to produce CO2,water vapour and energy. -Large amount of energy is produced (38 ATP molecules). -It occurs throughout the life of plants and animals. -C6H12O6+02------------>6CO2+6H2O+38ATP Glucose -------------> carbon-dioxide+water vapour+energy

How the cell caries blood into all the body parts?

Through blood vessels

.. ... 6 years, 4 months ago

The right upper chamber (atrium) takes in deoxygenated blood that is loaded with carbon dioxide. The blood is squeezed down into the right lower chamber (ventricle) and taken by an artery to the lungs where the carbon dioxide is replaced with oxygen. The oxygenated blood travels back to the heart, this time entering the left upper chamber (atrium). It is pumped into the left lower chamber (ventricle) and then into the aorta (an artery). The blood starts its journey around the body once more. Oxygenated blood is pumped from the heart along arteries, which are muscular. Arteries divide like tree branches until they are slender. The largest artery is the aorta, which connects to the heart and picks up oxygenated blood from the left ventricle. The only artery that picks up deoxygenated blood is the pulmonary artery, which runs between the heart and lungs.

Ask for details Follow Report by NetaBorra369 19.05.2015 Answers MessiFCB MessiFCB Helping Hand Time was measured by Sundials when pendulum clocks were not available. 4.6 18 votes THANKS 39 Comments Report smartbrainz Ace Time was measured during the period when pendulum clocks were not available with the help of devices like sundial, sand clock, shadow clocks, obelisks, water clocks, wrist watch, and equator clock. Explanation: •The discovery of pendulum clocks was done during the 15th century and that marked the era of precise timekeeping. Earlier to that period, many devices like sundial or the sand hour clocks were used. All these devices were quite primitive and had drawbacks to calculate the time precisely. Sundial for example was a type of shadow clock that depended on the shadow falling during a sunny day. •However, due to lack of shadows on a rainy or cloudy day, this could not accurately provide the time during winter or rainy seasons, when the sun was not visible. The Egyptian obelisks were also a type of shadow clocks. The hourglass or sand glass calculated the time with the passage of sand from the top to the bottom compartment of the glass. Astronomical clocks were used by the Eastern countries like China.

What is low pressure and when temperature increases does pressure also increases

Posted by Gaming Ghost Pro Player 6 years, 4 months ago

CBSE > Class 07 > Science

1 answers

.. ... 6 years, 4 months ago

A low pressure area, or a ‘low’ in short, is a region where the atmospheric pressure is lower than that of a surrounding area. Pressure is created by the number of collisions that occur between the molecules and the surface of container. If the temperature in the container is increased this will cause the molecules to move faster. As molecules move faster the number of collisions that will occur will increase. By increasing the number of collisions, this will increase the pressure in the container.
