using subtraction to determine the volume dispensed
making sure that you read the volume with the liquid inside the pipette at eye level
ensuring that air bubbles are not in the column of liquid inside the pipette
Answer:
The micrographs of cells shown in figure 8-3. what information about cells do these micrographs suggest is explained below in details.
Explanation:
Micrographs are the intensified images collected from small microscopes. Cell micrographs are often obtained from tissue specimens and show a constant mass of cells and inside compositions that are difficult to distinguish individually. It provides accurate images of the exteriors of cells and whole plants that are not imaginable by TEM. It can also be practiced for particle counting and size resolution, and method control.
Answer:
Bioluminescence
Explanation:
In the deep oceans, the sea cucumbers and polychaete worms use the bioluminescence for defense against predators and to find or attract prey by glowing so the predator can easily see it's glowing skin.
Growth Hormone and insulin are protein hormones that promotes the growth and regulation of substrate metabolism.
Explanation:
The Growth Hormone performs the metabolic actions in various tissues like liver, muscle, and pancreas through insulin growth factor. Insulin slows down the growth hormone signalling through the growth hormone receptor. It is important for maintaining the responsiveness of liver to growth hormone.
The insulin signalling pathway is very important in metabolic diseases like diabetes and aging. These insulin activates a phosphorylation cascade that branches to form a network affecting multiple biological processes.
The brownish-red powder on iron is called rust. It is formed by the reaction of iron and oxygen in the presence of water or air moisture. It is called oxidizing or rusting due to exposure to water and air.
The reactants are oxygen and iron the products are carbon dioxide and water and the process is oxidization.
