Answer:
A. The complementary shapes of an enzyme and a substrate
Explanation:
The Lock-and-Key model was made to show how an enzyme's active zone fits a substrate and how they bond together. It correlates just like a lock and a key; you have to have the correct-shaped key in order to open a lock. Same process of thought with the enzymes; you must have the same shape for both in order to bind together,
<h2><u>
Answer:</u></h2>
<u>cardic muscles:</u> are present only in the heart .single cell is not very strong by itself, millions of cardiac muscle cells working together are easily able to pump all of the blood in the body through the heart in less than a minute. Cardiac muscle cells have a branched shape so that each cell is in contact with three of four other cardiac muscle cells.
<u>characteristics of cardic muscles: </u> one nucleus ,striated, involuntary, branched and joined to one another by intercalated discs that contain gap junctions for depolarization between cells and hold the fibers together when the heart contracts.
5 Paramecium could be accommodated in this FOV.
Explanation:
FOV refers to the field of view of the microscope.
It is the maximum length or area of specimen you can observe in a single view.
If a single paramecium occupies 20 % of the Entire FOV.
Then the number of paramecium that will be accomodate 100% of FOV will be given by ,
Paramecium.
which is equal to 5.
Answer:
It's the same there is no change.
