in the figure, the boxed red letter ____ is in the thylakoid lumen and the boxed red letter ____ is in the stroma of the chloroplast.
Answers
In the figure, the boxed red letter c is in the thylakoid lumen and the boxed red letter a is in the stroma of the chloroplast.
Thylakoids are the flattened, membranous sac like structures inside the chloroplast which play important role in the light dependent reaction of photosynthesis. Stroma refers to the internal spaces of the chloroplast which consists of enzymes, chloroplast genome and starch granules which are used during Calvin cycle. These enzymes assist in reaction between ATP and NADPH to fix carbon from carbon dioxide into molecules that can be used to build glucose. These structures are very important for efficient processing of photosynthesis inside the plant. Photosynthesis is the process by which green plants make their own food inside the stomata of leaves using carbon dioxide and water in the presence of sunlight.

how does predicted resting membrane potential change as you increase k permeability? why is this the case?
Answers
As the K permeability increases, the predicted resting membrane potential will become more negative. The predicted resting membrane potential is determined by the Nernst equation.
This is because K has a negative charge, and as the permeability of the membrane to K increases, more K ions will flow down their electrochemical gradient into the cell, resulting in a greater negative charge inside the cell. This, in turn, will cause the predicted resting membrane potential to become more negative. For K, this equation is written as EK = RT/F ln[Kout/Kin], where R is the gas constant, T is the absolute temperature, F is Faraday's constant, and Kin and Kout are the concentrations of K inside and outside of the cell, respectively. As the K permeability increases, Kin will increase and Kout will decrease, resulting in a more negative EK. Therefore, as K permeability increases, the predicted resting membrane potential will become more negative.

you must directly expose cells to the uv light when attempting to disinfect because: (select all that apply) group of answer choices uv does not penetrate surfaces uv does not pass through plastic uv does not penetrate through the air uv does not pass through glass uv works best when not in direct contact with the cell
Answers
The correct answers are: Ultraviolet light does not penetrate surfaces.
UV does not pass through plastic.
UV does not penetrate through the air.
UV does not pass through glass.
In order to disinfect, cells must be directly exposed to UV light. UV does not work well when it is not in direct contact with the cell. Additionally, there are surfaces that UV light cannot penetrate, such as glass and plastic.
What is ultraviolet radiation (UV)?UV radiation is a form of electromagnetic radiation that is not visible to the human eye. It falls between visible light and X-rays on the electromagnetic spectrum. The sun is the most common natural source of UV radiation, but it can also be found in man-made sources like tanning beds and lamps. When exposed to too much UV radiation, it can cause sunburn, premature skin aging, and skin cancer.
What is the disinfecting effect of UV light?Ultraviolet light is a potent disinfectant. Because of this, UV light is commonly used to disinfect surfaces and drinking water. When UV radiation penetrates a cell's outer membrane and comes into touch with the DNA inside the cell, it can damage and break the DNA strands. When a cell's DNA is damaged, it cannot replicate and, as a result, dies. This makes UV light a highly effective disinfectant.

Answers
The most common complaint during coronary artery balloon catheterization is **a. chest pain**.
During coronary artery balloon catheterization, a catheter with a deflated balloon at its tip is inserted into a coronary artery to open a blockage and improve blood flow to the heart muscle. This procedure is commonly used in the treatment of coronary artery disease. Chest pain, also known as angina, is the most common complaint reported during the procedure. This chest pain can occur due to temporary blockage of blood flow during the inflation of the balloon or the release of chemicals that cause discomfort in the coronary arteries. The chest pain is typically monitored and managed by the medical team performing the procedure to ensure the patient's safety and well-being.
While other symptoms like headache, leg cramping, or even rare instances of diarrhea may occur during the procedure, chest pain is the most common complaint associated with coronary artery balloon catheterization.

A person has a disease that makes them have less energy and feel tired. What are two organelles the person's cells that might not be working correctly and causing this problem and why?
Answers
A person with a disease that causes them to have less energy and feel tired may be experiencing problems with two important organelles in their cells: the mitochondria and the lysosomes.
The mitochondria, often referred to as the "powerhouse of the cell," are responsible for producing the majority of a cell's energy in the form of ATP. If the mitochondria are not functioning properly, the cell will not be able to produce enough energy, leading to feelings of fatigue. This can happen as a result of mutations in the mitochondrial DNA or dysfunction in the electron transport chain, which is responsible for producing ATP.
Another organelle that may not be working correctly in this person's cells is the lysosome. Lysosomes are responsible for breaking down and recycling cellular waste, including damaged organelles and debris. If the lysosomes are not functioning properly, the waste products will build up in the cell, leading to a decrease in overall cell function and energy. This can happen as a result of genetic disorders such as lysosomal storage diseases.

A product is sold at a price of $120 per unit and its variable cost is $80 per unit. The fixed expenses of the business are $8,000 per year. Find (i) BEP in $ and units, (ii) profits made when sales are 240 units. Calculate the profit and do a CVP Analysis.
Answers
(i) BEP in $: $8,000
BEP in units: 100 units
(ii) Profits made when sales are 240 units: $4,800
(i) BEP in $ and units:
To find the Break-Even Point (BEP) in dollars, we need to divide the fixed expenses by the contribution margin per unit. The contribution margin per unit is the selling price minus the variable cost per unit.
BEP in $ = Fixed expenses / Contribution margin per unit
BEP in $ = $8,000 / ($120 - $80) = $8,000 / $40 = $8,000
The BEP in dollars is $8,000.
To find the BEP in units, we divide the fixed expenses by the contribution margin ratio.
BEP in units = Fixed expenses / Contribution margin ratio
Contribution margin ratio = Contribution margin per unit / Selling price per unit
Contribution margin ratio = ($120 - $80) / $120 = $40 / $120 = 1/3
BEP in units = $8,000 / (1/3) = $8,000 * 3 = 300 units
The BEP in units is 300 units.
(ii) Profits made when sales are 240 units:
To calculate the profit, we need to subtract the total costs (fixed costs + variable costs) from the total sales.
Variable costs = Variable cost per unit * Number of units sold
Variable costs = $80 * 240 = $19,200
Total costs = Fixed expenses + Variable costs
Total costs = $8,000 + $19,200 = $27,200
Profit = Total sales - Total costs
Profit = (Selling price per unit * Number of units sold) - Total costs
Profit = ($120 * 240) - $27,200
Profit = $28,800 - $27,200
Profit = $1,600
The profit made when sales are 240 units is $1,600.
CVP Analysis:
Cost-Volume-Profit (CVP) analysis is a tool used to analyze the relationship between costs, volume, and profits. It helps in understanding how changes in sales volume affect profitability.
In this case, the CVP analysis can be performed using the given data:
Sales revenue = Selling price per unit * Number of units sold
Sales revenue = $120 * 240 = $28,800
Variable costs = Variable cost per unit * Number of units sold
Variable costs = $80 * 240 = $19,200
Contribution margin = Sales revenue - Variable costs
Contribution margin = $28,800 - $19,200 = $9,600
Contribution margin ratio = Contribution margin / Sales revenue
Contribution margin ratio = $9,600 / $28,800 ≈ 0.3333
Break-Even Point (BEP) in units = Fixed expenses / Contribution margin per unit
BEP in units = $8,000 / $40 = 200 units
Profit = (Selling price per unit * Number of units sold) - Total costs
Profit = ($120 * 240) - ($8,000 + $19,200)
Profit = $28,800 - $27,200
Profit = $1,600
By conducting a CVP analysis, we can determine the Break-Even Point, contribution margin, and analyze the profitability based on the given data.

what name is given to the process in which the information encoded in a strand of mrna is used to construct a protein? rna processing gene expression polypeptide formation transcription translation
Answers
The name given to a process in which the information is encoded in a strand of mRNA will be used to construct a protein is translation. Option E is correct.
Translation is a fundamental process in molecular biology that occurs in the cytoplasm of cells. It involves the conversion of the genetic information carried by the mRNA molecule into a specific sequence of amino acids, which are the building blocks of proteins.
Before translation can occur, the genetic information stored in the DNA is first transcribed into mRNA. During transcription, an enzyme called RNA polymerase synthesizes a complementary mRNA molecule by reading and copying the DNA sequence of a gene.
The newly synthesized mRNA undergoes several processing steps in the nucleus, including the addition of a cap and a poly-A tail, as well as the removal of introns.
During elongation, the ribosome moves along the mRNA molecule, reading each codon (a sequence of three nucleotides) and bringing in the corresponding amino acid.
When a stop codon is reached, it signals the end of translation. The newly synthesized polypeptide chain is released from the ribosome, and the mRNA molecule is also released.
Hence, E. is the correct option.

3. Testosterone
4. Glucagon
5. PYY
6. Leptin
Answers
If a human can continuously eat without feeling full, they might be in deficit of the hormone leptin, option 6 is correct.
Leptin is primarily produced by fat cells and acts as a satiety hormone, signaling to the brain that the body has sufficient energy stores. It helps regulate appetite and energy balance by suppressing hunger and increasing energy expenditure. When leptin levels are low or the body becomes resistant to its effects, the brain doesn't receive the signal that the body is satiated, leading to excessive food intake and a lack of feeling full.
While the other hormones listed, such as glucose, neuropeptide Y, testosterone, glucagon, and PYY, may play a role in appetite regulation and energy balance, leptin is specifically associated with signaling fullness and satiety. Its deficiency or resistance can disrupt the normal feedback loop between the body and the brain, resulting in continuous eating without feeling satisfied, option 6 is correct.
