A general function of membranes in the cell is to
Answers
Answer
According to ThoughtCo,
The cell membrane (plasma membrane) is a thin semi-permeable membrane that surrounds the cytoplasm of a cell. Its function is to protect the integrity of the interior of the cell by allowing certain substances into the cell while keeping other substances out.
Hope this helps! <3
Answer:
The cell membrane, therefore, has two functions: first, to be a barrier keeping the constituents of the cell in and unwanted substances out and, second, to be a gate allowing transport into the cell of essential nutrients and movement from the cell of waste products.

what is the main advantage of small cell size
Answers
Answer:
The advantage of small cell size is that substances like organic molecules and ions can diffuse easily into the cells whereas wastes can diffuse easily out of the cells.
As a cell’s size increases, its volume increases much more rapidly than surface area.

When you use the same histone protein as your standard, you determine the histone protein concentration to be 5 mg/ml. Explain the discrepancy (pick ONE answer): (5 points) a. The histone protein has fewer basic amino acids than albumin. b. The histone protein has more acidic amino acids than albumin c. The histone protein has more basic amino acids than albumin d. The histone protein contains more methionine than albumin
Answers
Answer:
A. The histone protein has fewer basic amino acids than albumin
Note: The question is incomplete. The complete question is given below:
You use the Bradford (coomassie) assay to determine the concentration of a whey protein. You use bovine albumin as your standard. You determine the histone protein concentration to be 3 mg/ml. When you use the same whey protein as your standard, you determine the histone protein concentration to be 5 mg/ml. Explain the discrepancy (pick ONE answer): (2 points) The histone protein has fewer basic amino acids than albumin. The histone protein has more acidic amino acids than albumin c. The histone protein has more basic amino acids than albumin d. The histone protein contains more methionine than albumin
Explanation:
The Bradford assay measures the concentration of proteins in a a protein sample using a color change that occurs from brown to blue when the protein in the sample binds to Coomassie dye. The Coomassie dye specifically binds to basic and aromatic amino acids in the protein. A standard curve is created using absorbance data from samples of proteins of known concentrations. The spectrophotometer is set to read at 595 nm in the Bradford assay as the peak absorbance of Coomassie Blue once bound to proteins occurs at 595 nm.
The higher the concentration of proteins, the higher the color intensity and the higher the absorbance values.
Since when bovine serum albumin was used as standard, the sample protein concentration was lesser than when the protein sample was used as standard, this means that the sample protein binds less to Coomassie dye as a standard thereby giving a higher sample protein concentration than the BSA standard. Therefore, the histone protein has fewer basic amino acids than albumin.

Calculate the oxygen partial pressure, in torr, at which 97% of myoglobin molecules exist in the oxygen-bound state. Assume p50(Mb).
Answers
Answer:
Partial pressure of oxygen = 90.53 torr
Explanation:
Using the formula; YO₂ = (pO₂)ⁿ / (pO₂)ⁿ + (p₅₀)ⁿ
where Y is the fraction of oxygenated myoglobin, pO₂ is the partial pressure of O₂, expressed in torr (760 torr = 1 atmosphere) and p₅₀ is the partial pressure of O₂ required to bind 50% of the myoglobin molecules, n is Hill's constant which describes the degree of cooperativity among interacting ligand sites or subunits
p₅₀ = 2.8 torr
n = 1 for myoglobin calculations since it only contains one heme group
YO₂ = 97% or 0.97
pO₂ = x
substituting the values
0.97 = x (2.8 + x)
x - 0.97x = 2.716
0.03x = 2.716
x = 2.716 / 0.03
x = 90.53 torr

In the diagram above, where is light energy converted to chemical energy?
Answers
Answer:
There is no diagram in this question, however, the question can be answered based on general understanding.
Light energy is converted to chemical energy by PLANTS (GRASS) i.e from the sun to grass
Explanation:
This question is trying to depict a food web or chain of organisms feeding on one another in order to obtain energy. However, in this process, only one organisms amongst the list of organisms is capable of converting LIGHT energy to CHEMICAL ENERGY.
This organism is called a PRODUCER and it is the GRASS (plant). Green plants like the grass in this question are autotrophs i.e. are capable of producing their own food via the process of PHOTOSYNTHESIS. In this process of photosynthesis, plants capture light energy from the sun and convert it to chemical energy stored in sugars.

A. Influenza started off in the lysogenic cycle.
B. Influenza is a lytic cycle virus
C. Influenza remained dormant after the war.
D. Influenza replicates using mitosis.
Answers
Answer I think its c srry if im wrong it just makes sense
Explanation:
Influenza virus was so deadly worldwide because Influenza started off in the lysogenic cycle.
What do you mean by lysogenic cycle?The lysogenic cycle is a method by which a virus can replicate its DNA using a host cell. Lysogeny, or the lysogenic cycle, is one of two cycles of viral reproduction Lysogeny is characterized by integration of the bacteriophage nucleic acid.
The phage infects a bacterium and inserts its DNA into the bacterial chromosome, allowing the phage DNA (now called a prophage) to be copied and passed on along with the cell's own DNA.
In the lysogenic cycle, phage DNA is incorporated into the host genome, forming a prophage, which is passed on to subsequent generations of cells. Environmental stressors such as starvation or exposure to toxic chemicals may cause the prophage to be excised and enter the lytic cycle.
