Answer:
When a bullet strikes, a characteristic ‘keyhole’ is formed—a defect that is circular at one end with tangential fractures radiating outwards in parallel, allowing the bone between them to lever out. So, in other words a major surgery is needed to get the bullet out. It is very risky as well
Explanation:
Answer:
increases; protein denaturation occurs
Explanation:
One of the characteristic of enzymes is the sensitivity to temperature .
Enzymes are sensitive to the changes in the environmental temperature.The enzymatic activities increases with increase in temperature,up to the optimum of 37 degrees in most animals.
However,once the optimum temperature has been exceeded,enzyme activities drops.This is because below optimum the rate of collision between the enzyme active sites and substrate molecules is very high,therefore more products are formed which increases the rate of reactions.
At temperature above the optimum,the high temperature breaks the bonds,especially the hydrogen bonds holding the 3D structure of the active sites.Therefore,substrate molecules can not fit into the active site,and therefore enzymatic actives of the enzyme is affected,and the enzyme is said to be denatured
Answer:
As John is testing the effect of temperature on the solubility of sugar in water. To test this, he will measure the amount of sugar dissolved at different temperature level.
Answer:
tissue
Explanation:
a tissue is a group of cells that work together to perform a common function
Activation energy - is the minimum quantity of energy that the reacting species must possess in order to undergo a specified reaction.
