Which macromolecule is a primary component of cell walls, and which argument provides evidence for how the structure of this mol

ecule relates to its purpose within the cell wall?
A Lipids are the primary component, and they repel and prevent excess uptake of water because they form carbon chains.

B Lipids are the primary component, and they protect the cell and help maintain its shape because they form carbon rings.

C Carbohydrates are the primary component, and they repel and prevent excess uptake of water because they form carbon chains.

D Carbohydrates are the primary component, and they protect the cell and help maintain its shape because they form carbon rings.

The DNA in a cell's nucleus encodes proteins that are eventually targeted to every membrane and compartment in the cell, as well
spayn [35]

Answer:

PFK (protein): cytoplasm only (targeting pathway)

Insulin (protein): ER->Golgi->outside cell

Explanation:

Translation can be described as the mechanism by which a protein is produced through a mRNA.

If a particular protein is to function inside the same cell, then it doesn't need to get any modification so that it can travel outside the cell. Such type of proteins are translated on free cytoplasmic ribosomes and are released directly into the cytoplasm to perform their function. For example, PFK protein.

If a protein has to function outside the cell where it is produced, then it has to be modified. Such type or proteins are translated on the rough ER.  They are then modified in the Golgi complex and then transported outside the cell to the area where they have to function. For example, insulin.

Citrus2011 [14]

The inside of the barrel-shaped LDL protein consists of hydrophobic amino acids, while its outside portions in contact with the blood fluid consist of hydrophilic amino acids.

LDL is a type of lipoprotein, i.e., it contains protein as well as lipid (cholesterol). The full form of LDL is Low Density Lipid. LDL is considered to be the bad cholesterol for the body. It can cause diseases of the heart like heart attack or stroke.

Amino acids are the essential molecule that act as a monomer for the formation of proteins inside the body. They contain an amino group and  a carboxylic group attached to the same carbon atom. There are also a hydrogen atom and a variable R group attached to the carbon, also called the alpha carbon.

A serial dilution is performed on a culture of Saccharomyces cerevisiae (Brewer's yeast). A 1:10 dilution was performed in serie
Karo-lina-s [1.5K]

Answer: CFU/mL = 14200 CFU/mL

Explanation:

Microorganisms are very small and difficult to count directly. Instead, a laboratory technique is used to count CFUs (Colony Formation Units). This involves making dilutions of a microbial suspension and spreading it on thin layers of agar containing nutrients for growth in Petri dishes also called agar plates. After incubation under ideal conditions, some plates are completely covered with microbial growth; some have little or no growth; and some are covered with individual isolated "spots", which are microbial colonies. Since a colony may consist of a single organism or a group of microbes, the dots represent a CFU.

To calculate the viable count of the stock culture, you have to count the number of colonies, multiply by the dilution and the result will be the plate count in CFU.

So, the equation is:

CFU/mL = Number of colonies / (Volume trasferred to plate x dilution blank)

100 microliters = 0.1 mililiter

1/10 = 0.1 (dilution factor)

Replacing the information from the question:

CFU/mL = 142 / (0.1 mL x 0.1)

CFU/mL = 14200 CFU/mL
