Chemistry

It is 2.1 x 10^3 because your base number needs to be in between 1 and 10, and the number you are converting is non-decimal, so the exponent is positive. It is 10^3 because you are moving the decimal 3 places to the right

Answer:

2.1 × 10³

Explanation:

In scientific notation we move the decimal place until there is just one number to the left of it in the ones position meaning we would put the decimal in between the 2 and the 1.  To make up for the decimal change we represent it with 10 to a specific power, the power it goes to is how many places we need to move the decimal.  Because in this case we moved it past 3 numbers we will multiply 2.1 by 10 to the 3rd power which will look like this

2.1 × 10³

I hope this helps and please don't hesitate to ask if there is anything still unclear!

What should be the effect of losing ones sight on the ability to digest food
crimeas [40]

One mechanism is enzyme induction.

Enzymes are proteins, which are metabolically expensive to produce. It makes evolutionary sense that your body makes less digestive enzymes such as lactase and sucrase when they're not needed. If your diet changes, your body can gradually increase the production of some enzymes through a process of enzyme induction.

For example, the production of lactase enzyme can be increased in some lactose-intolerant individuals by feeding them lactose . Also, studies in rats have shown that other carbohydrate-digesti<span>Your body makes more of what it needs, and less of what it doesn't need--brilliant!</span>ng enzymes, such as sucrase-isomaltase, trehalase, and maltase-glucoamylase--can be induced by hydrocortisone administration.

Solid liquid gas or plasma. Solid would be ice cubes (frozen state), liquid would be the water inside of the glass, the gas would be when you take that same water and place it on a stovetop to bring to a boiling point. (Gas state) and finally the plasma state is when you your gas particles (from the gas state) if you heat the gas particles, they will turn to plasma.
