Answer:
159.808 g/mol
Explanation:
Br itself is 79.904 g/mol. So multiply it by two.
The molar mass of [tex]Br_{2}[/tex] is approximately 159.808 grams per mole.
When calculating the molar mass of [tex]Br_{2}[/tex], also known as diatomic bromine, the atomic masses of the two bromine atoms (Br) found in the molecule are added together.
Bromine (Br) has a mass of roughly 79.904 grammes per mole according to its atomic weight.
Because of this, the molar mass of [tex]Br_{2}[/tex] is calculated as follows: 2 times 79.904 g/mol = 159.808 g/mol
As a result, the amount of grammes that constitute one mole of [tex]Br_{2}[/tex] is roughly 159.808.

where are peripheral proteins located
Answer:
Explanation:
Peripheral membrane proteins are found on the outside and inside surfaces of membranes, attached either to integral proteins or to phospholipids. Unlike integral membrane proteins, peripheral membrane proteins do not stick into the hydrophobic core of the membrane, and they tend to be more loosely attached.

When your cells use fat for energy, the fatty acids are broken up into molecules of acetyl CoA. Predict how many ATP can be made from one molecule of acetyl CoA if oxygen is present. Show your work.
Answer: Suppose that each fatty acid in a certain fat can make 9 molecules of acetyl CoA. Predict how many ATP can be made from the fatty acids in this fat. This would make 27 acetyl CoA, and therefore would make 27 ATP

What is the function of the surface protein on the influenza virus?
A To protect
B To attach to a host cell
C To manufacture enzymes using a host's immune system
D To remove a host cells's DNA
Surface proteins are the proteins that are embedded in the cell membrane structure of organisms and help in cell interaction with the outer surrounding or other cells.
Surface protein on the influenza virus is needed for attaching to the host cell.
The surface protein of viruses can be explained as:In viruses, the genetic material is stored in these protein structures called capsids which protects the viral genetic material from degrading enzymes and other cellular enzymatic activities.Surface proteins on the viruses are needed to penetrate and attach to the host system and cells for inducing immune response and diseases.The surface proteins of influenza virus HA and NA are necessary for penetrating host mucus layers.Therefore, option B to attach to the host cell the surface proteins are needed.
