Explanation:
first of all our eyes recognise to train and send the message to our brain then our ears and then the brain send motor impulses to muscles of leg
<u>Answer</u>:
Substance A affects the amount of the activation energy needed by the process by catalyzing the reaction. Enzymes are the natural biological catalyst that lowers the activation energy for a reaction to proceed faster at a low energy requirement.
<u>Explanation</u>:
The reactants in the solution react to form a product. For a reaction to happen some energy is needed. The energy which helps reactants to break some bonds and make other bonds to make a product is known as activation energy.
Enzymes are the biological molecules which lower this activation energy by catalyzing the reaction by helping in breaking old bonds and forming new bonds to create a product.
Answer:
It is true
Explanation:
The aerobic exercises produce an acceleration in metabolic process. To obtain the necessary energy to do them, the body start to use the carbohydrates. After transforming these carbohydrates into energy, if the body is still in movement, to continue producing energy, the body will continue with the lipids present in the body. In this way, doing aerobic exercises, the carbohydrates and lipids that was used, reduces the volume (and mass) of tissues, in general, from all the body.
Answer:
An inclined plane is a simple machine. An inclined plane is a ramp used to reduce the effort needed to raise or lower an object over a vertical height.
It is easier to climb stairs to get to a second floor than to climb straight up a rope. It is easier to walk up a long, gentle hill than to climb up a short, steep hill
, both condition work is done by gravity which is conservative force. So work is same. But if we will take friction force then for your kind information total world done on plane will be more than stairs due to longer path of plane were against of non conservative force.
The following are examples of inclined planes:
* Loading ramp
* Stairs or wheelchair ramp
* Mountain road
* Threaded screw.
The ancient Egyptians used inclined planes, or ramps, to move huge blocks of stone to build the pyramids.
