2. a. one purpose of the blood test was to test his creatine kinase enzyme to see if there were any medical conditions connected to the way he was walking and why it was abnormal

In living things, cells must be in a _____________________ solution where water leaves and enters the cell at _________________________________________.

Answers

Answer:

isotonic; the same rate

Explanation:

Cell Theory as as commonly known gives the best definition for cells. All organisms that ever existed are made up of one or more cells. The theory state that the cell is a basic unit, that is of all living things, and that all cells come from cells that have existed.

When the level or concentration of solute in and out of the cell is at the same pace or level, the the cell membrane does not allow solutes to cross, leading to the solution being isotonic to the cell.

Answers

Answer and Explanation:

The transport and digestion of proteins is done by other proteins called enzymes. An example of this occurs in the biochemical digestion of proteins, where the enzyme pepsin promotes digestion, the breakdown of proteins into smaller pieces, through hydrolysis which is the breakdown of molecules with the use of water. These pieces of the protein are transported to the duodenum where they are digested again by the enzyme enterokinase.

An element is define as a type of substance that is impossible to  break into smaller pieces by the help of chemical process. There are several rules that should be followed at the time of assinging name of the elements. The first rule is name of the element is not a proper noun. The second rule is the symbols of the element that must be of one or more than one symbol.

Density is define as the mass per unit volume it means that 1 kg mass present in 1 meter cube is called density, density is also states that the how compact an material.

Mathematically

Density = mass/volume

S.I unit of density is kg/m^3

Density is higher in solid as compare to liquid and density of liquid is higher than gas so density is in order of SOLID>LIQUID>GAS. So we know that solid is compact in nature as compare to liquid and gas.

When we doing Strawberry Extraction, why do we need to remove the air as much as possible before seal the bag?

Answers

to keep it preserved and delicious

Answer:

Why do we need to cool the mixture? DNases or restriction enzymes that destroy DNA are present in the cell's cytoplasm. They are there to protect the cell from invasion by viruses. Once the nuclear membrane is destroyed by the soap, the DNA is now susceptible to the DNases and will quickly be degraded.

Explanation:

When you added the salt and detergent mixture to the smashed strawberries, the detergent helped lyse (pop open) the strawberry cells, releasing the DNA into solution, whereas the salt helped create an environment where the different DNA strands could gather and clump, making it easier for you to see them.
