A 74-year-old woman has more air in her lungs than normal, and breathes with an inflated chest. Do you think an inflated chest would make breathing uncomfortable? would it alter the rate of breathing, or the volume of each breath?.
Answers
Yes, an inflated chest would make breathing uncomfortable because of the reduced capacity of the lungs. A 74-year-old woman has more air in her lungs than normal, and breathes with an inflated chest. This could be caused by emphysema or chronic obstructive pulmonary disease (COPD).
These diseases cause the air sacs in the lungs to break down, leading to less surface area for gas exchange and less lung elasticity, which is why the chest is overinflated and breathing is affected.An inflated chest can alter the rate of breathing as well as the volume of each breath. Since there is less surface area for gas exchange, the individual will need to breathe more frequently to get enough oxygen into their bloodstream. The body will compensate by taking shallow breaths, which may cause the individual to feel short of breath. Since the chest is already inflated, the lungs are unable to expand as much as they would like to, resulting in a decrease in the amount of air that can be taken in and out of the lungs with each breath.In conclusion, an inflated chest caused by emphysema or COPD can make breathing uncomfortable, alter the rate of breathing, and reduce the volume of each breath.

4. 13 Cell culture using whey Waste dairy whey is used to grow Kluyveromyces fragilis yeast in a continuous culture system operated at 30C and 1 atm pressure. Medium containing 4% w/w lactose (C12H22O11) and 0. 15% w/w NH3 flows into a specially designed aerated bioreactor at a rate of 200 kg h21. The reactor is compartmentalised to facilitate gravity settling of the yeast; a suspension containing concentrated cells is drawn off continuously from the bottom of the reactor at a rate of 40 kg h21 , while an aqueous waste stream containing 0. 5 kg cells per 100 kg leaves from the top. All of the lactose provided is utilised by the culture. The biomass yield from lactose is known from preliminary experiments to be 0. 25 g g21. The composition of the K. Fragilis biomass is determined by elemental analysis to be CH1. 63O0. 54N0. 16 1 7. 5% ash. (a) What is the RQ for this culture
Answers
The respiratory quotient (RQ) is the ratio of the amount of CO2 produced to the amount of O2 consumed in a reaction or metabolic process, and it is used to determine the metabolic pathway being used during the process. The RQ for this culture is 1.28.
The formula for determining the RQ is as follows:
RQ = CO2 produced / O2 consumed
The oxygen consumed by the yeast can be calculated using the biomass yield equation as follows:
Biomass yield from lactose = Yx/s = 0.25 g/g
Lactose consumed = 4% w/w = 0.04 * 200 kg/h = 8 kg/h
Lactose molecular weight = 12 + 22 + 11 + 11 + 11 + 11 = 78 g/mol
Moles of lactose consumed = 8000 / 78 = 102.6 mol
Oxygen required = 102.6 * (12 + 1 + 16 * 2) = 5552.8 mol/h
CO2 produced can be calculated using the composition of K. fragilis biomass as follows:
Carbon content in K. fragilis biomass = (1 * 1.63) / (1.63 + 0.54 + 0.16) = 0.73CO2 produced = 0.73 * 0.25 * 102.6 * (12 + 16 * 2) = 3156 mol/h
The RQ can now be calculated using the equation above:
RQ = CO2 produced / O2 consumed= 3156 / 5552.8= 1.28
Therefore, the RQ for this culture is 1.28.

Chromosomes are doubled I what part of the cell cycle
Answers
Chromosomes are doubled in the S phase (synthesis phase) of the cell cycle. During the S phase, the DNA of the chromosomes is replicated, resulting in the formation of identical copies of each chromosome, or sister chromatids. These sister chromatids are joined at a central point called the centromere. After replication is complete, the cell has twice the amount of DNA as it did before replication, and each chromosome is composed of two identical sister chromatids. This process of DNA replication is critical for the cell to be able to divide and produce two identical daughter cells, each with the same genetic information as the parent cell.

How do you distinguish tornado and down burst at a given
location after the event had occurred? Describe in detail the role
of vorticity in the formation of the supercells
Answers
Tornadoes and downbursts are two of the most destructive weather phenomena on earth. While both of them can create strong winds, it's important to distinguish between the two to avoid confusion.
To differentiate between the two, the following steps can be taken:After the event has occurred, check the damage path. Tornadoes can leave a relatively narrow, twisted path that can be hundreds of yards long. On the other hand, the damage from a downburst is often straight-lined and can be more widespread in terms of coverage area.Check the direction of the damage. In a tornado, the damage will generally be aligned with the direction of the wind, but in a downburst, the damage will often be perpendicular to the direction of the wind.
Check the atmospheric conditions before the storm. If a tornado is expected, the atmosphere will be charged with energy and very unstable. A downburst, on the other hand, can be caused by a simple thunderstorm. So, if the atmospheric conditions were calm and there was no warning of a tornado, then it was probably a downburst.Vorticity is a term used to describe the rotation of air masses around an axis or an imaginary line. It is a crucial component of supercell formation. When wind shear is present, vorticity can be created in a supercell.
A supercell is a thunderstorm with a rotating updraft. When this happens, a horizontal tube of spinning air is created, and this tube can be stretched and rotated vertically, forming a mesocyclone. A mesocyclone is the precursor to the formation of a tornado. The strength of the vorticity in the mesocyclone is what determines whether a tornado will form or not. The stronger the vorticity, the more likely a tornado will form. Therefore, vorticity plays a significant role in the formation of supercells.

Your book defines pH as the "measure of the relative acidity of a solution, ranging in value from o (most acidic) to 14 (most basic). pH stands for potential hydrogen and refers to the concentration of hydrogen ions" (G-12) Living organisms (e.g., plants, animals, bacteria) require careful control of their internal pH, since they are sensitive to even small changes in pH. Homeostasis is the maintenance, by living organisms, of stable surroundings; this includes pH, as well as temperature, osmolarity, and a number of other environmental variables. 1. Explain how organisms that require a neutral environment survive and function despite metabolic activities that tend to shift pH toward either acidic or basic ends of the pH scale? Be specific!
Answers
In order to keep the internal pH within the desired range, living organisms have evolved a number of mechanisms.
The mechanisms that help to regulate pH and keep it in a neutral range are as follows:
Buffer systems, Respiratory systems, Renal systems, and Other compensatory mechanisms.
Buffer systems: A buffer is a solution that resists changes in pH when small amounts of acid or base are added to it. They are present in the body's fluids and keep the pH from becoming too acidic or too basic.Respiratory systems: The respiratory system is responsible for removing carbon dioxide from the body, which can cause the blood to become acidic. As carbon dioxide leaves the body, it decreases the amount of acid in the blood.Renal systems: The kidneys help to regulate the body's pH by removing excess acid or base from the body. They can secrete excess acid into the urine, which is excreted from the body.Other compensatory mechanisms: There are other compensatory mechanisms that the body can use to regulate pH. For example, cells can change the number of hydrogen ions that they produce or remove. Additionally, the body can release bicarbonate ions, which can neutralize excess acid in the bodyLearn more about Homeostasis at:

Marcus consumes about 100 grams of protein each day. Of this, 25 grams is broken down and used to make ATP, and 25 grams is used to synthesize (make) body fat. What does this tell you about Marcus's protein and calorie intake?
Answers
This is because he consumes 100 grams of protein each day, and it is not mentioned that he consumes any additional protein beyond this amount.
What is ATP?
ATP stands for adenosine triphosphate, which is a molecule that is commonly referred to as the "energy currency" of the body. ATP provides the energy that is required for most cellular processes, including muscle contraction, nerve impulse transmission, and protein synthesis.
The structure of ATP consists of three phosphate groups attached to an adenosine molecule. When ATP is used to provide energy for cellular processes, one of the phosphate groups is broken off, releasing energy in the process. This results in the formation of ADP (adenosine diphosphate), which can be converted back into ATP through the addition of a phosphate group.
We also know that 25 grams of the protein he consumes is used to make ATP, which is the primary energy source used by the body. This means that Marcus's body requires a significant amount of energy each day, and that he is likely consuming enough calories to support this energy demand.
Finally, we know that 25 grams of the protein he consumes is used to synthesize body fat. This suggests that Marcus may be consuming more calories than he needs, as excess calories are typically stored in the body as fat.
