In pulsus paradoxus, even if the pulse cannot be palpated, it can still be heard by using a BP cuff and stethoscope.
a. True
b. False
Answer:
False.
Explanation:
Pulse can't be heard by using a BP cuff and stethoscope because these devices are used to measure the heartbeat and blood pressure of the body. Digital monitors display both blood pressure and heart rate, but you can determine the pulse by checking your pulse by using hand while on the other hand, heartbeats can easily be heard using a good stethoscope so we can say that pulse can't be heard through BP cuff and stethoscope.

Explanation:
A penicillin reaction is a life-threatening event. In those who are allergic to penicillin, the drug acts as a __________ that binds to blood proteins, causing a strong immune response.
Answer:
A penicillin reaction is a life-threatening event. In those who are allergic to penicillin, the drug acts as a hapten that binds to blood proteins, causing a strong immune response.
Explanation:
Low molecular weight chemicals can bind to antibodies, but cannot activate B lymphocytes by themselves (they are not immunogenic). To generate specific antibodies to these small chemicals, immunologists typically bind them to macromolecules prior to immunization. In these cases, the chemical is called a hapten. Penicillin G is a typical hapten that tends to covalently bind to lysine residues both in solution and in protein-bound cells. Penicillin is a drug that behaves as a hapten, since the beta-lactam ring under physiological conditions opens and reacts with the lysine residues of proteins, forming a complex that is the main antigenic determinant of penicillin and other beta-lactams and is capable of to stimulate responses mediated by antibodies or by T cells.

When he analyzes its chemical structure, he finds that it contains uracil, is single stranded, and contains phosphate. What molecule has likely contaminated his mixture?
nucleotide
protein
DNA
RNA
Answer:
RNA
Explanation:
A ribonucleic acid (RNA) is one of two types of nucleic acid made up of nucleotide subunits. RNA is a single stranded molecule unlike DNA, which is double stranded. The nucleotide unit of nucleic acids is composed of a nitrogenous base (Adenine, Guanine, Cytosine and Thymine/Uracil), a pentose sugar (ribose and deoxyribose) and a phosphate group.
One of the key structural differences between RNA and DNA is that RNA contains URACIL nitrogenous base instead of THYMINE in DNA.
According to this question, a scientist finds that another molecule has contaminated the mixture he is working with in the lab. When he analyzes its chemical structure, he finds that it contains uracil, is single stranded, and contains phosphate. This illustrates that the contaminating molecule is a specific type of nucleic acid called RNA.

Use the coordinates of the labeled point to find the point-slope equation of
the line
-5
5
-5
(3.-5)
O A. y+ 5 = -3(x - 3)
B. y- 5 = -3(x+3)
C. y + 5 = 3(x+3)
O D. Y-3 - (x+5)
Answer:
A. y + 5 = -3(x - 3)
Explanation:
Given the following data;
Points on the graph (x1, y1) = (3, -5)
Points on the graph (x2, y2) = (0, 4)
First of all, we would determine the slope of the equation of line;
Mathematically, the slope of a line is given by the formula;
[tex] Slope, \ m = \frac {Change \; in \; y-axis}{Change \; in \; x-axis} [/tex]
[tex] Slope, \ m = \frac {y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]
Substituting into the formula, we have;
[tex] Slope, \ m = \frac {4 - (-5)}{0 - 3} [/tex]
[tex] Slope, \ m = \frac {4 + 5}{0 - 3} [/tex]
[tex] Slope, \ m = \frac {9}{-3} [/tex]
Slope, m = -3
Next, to find the point-slope equation of the line, we would use the following formula;
y - y1 = m(x - x1)
y - (-5) = -3(x - 3)
y + 5 = -3x + 9
y = -3x + 9 - 5
y = -3x + 4 = mx + c
Complete the sentences on the control of the cell cycle with the correct terms. After S phase ____________ appear to share a common centromere.
Answer:
After S phase sister chromatids appear to share a common centromere.
Explanation:
The cells of the different organisms go through different periods during their life, each one characteristic and well differentiated. Before the mitosis process, during the S phase of the cell cycle, the chromosomes replicate, so that at the time of initiating cell division in humans, each of the 46 replicated chromosomes will have two chromatids joined by the centromere, each one of them represents a functional chromosome. Each sister chromatid of a chromosome secretes a daughter cell, as do the other 45, and together they will make up the diploid "cluster" of 46 chromosomes from the new cell. In other words, each chromosome is made up of two chromatids that come together at a point called the centromere. One chromatid contains a condensed chromatin molecule and the other has another identical chromatin molecule, the result of DNA replication, which is why we talk about a sister chromatid chromosome. Each chromatid has two arms of equal or different length.
Solutions having osmotic pressures more than those of body fluids are called Group of answer choices hyposmotic. neosmotic. hyperosmotic. magnosmotic. isosmotic.
Answer:
hyperosmotic
Explanation:
Osmosis across a membrane occurs in nature as a result of concentration gradient i.e. difference in the solute concentration. Based on the concentration of solute in a solution which determines the osmotic pressure, a solution can either be hyperosmotic, hypoosmotic or isosmotic.
A hyperosmotic solution is that solution which contains more solute concentration in relation to another solution. In essence, a hyperosmotic solution will have more osmotic pressure than that of the body fluid. This will cause water to flow out of the body into the solution.
A membrane consisting only of phospholipids undergoes a sharp transition from the crystalline form to the fluid form as it is heated. What would be the effect on this transition in a membrane containing 80% phospholipid and 20% cholesterol
Answer:
Having 20% cholesterol in a membrane would reduce the fluidity.
Explanation:
At high temperatures, cholesterol stabilizes the membrane and increases the melting point.
The plasma membrane is the layer that surrounds the cell and is composed of cholesterol and phospholipid. The presence of cholesterol reduces the fluidity and transition.
What are the components of the plasma membrane?The plasma membrane separates the exterior and the interior of the cell and through a semi-permeable nature allows the transport of the molecules. It is composed of phospholipids and cholesterol molecules.
The phase transition of the membrane is known by the change in the rigidity as it starts free-flowing at a high temperature called transition temperature.
In the presence of cholesterol, the movement and the fluidity reduce as it interferes with the fatty acid chain and now requires more temperature to convert the rigid structure to become fluid.
Therefore, membrane-containing cholesterol requires more temperature to modify the fluidity as compared to phospholipids alone.

What organisms help break down dead leaves in an ecosystem
Answer:
Decomposers are vital organisms that grow by breaking down dead and decaying matter. Some of these are scavengers - macro-organisms that feed on dead or decaying matter, e.g. flies, cockroaches, earthworms. Others are decomposers, generally microscopic bacteria and fungi, that break down wastes.
Explanation:
Individuals with premutation length repeats in FMR1 may have some of the phenotypes of Fragile X but not others, which is _____________; for example, some individuals may have cognitive deficiencies, while others might have late onset ataxia. In addition, some individuals will have no phenotypes of the condition at all, due to ____________.
Answer:
variable expressivity; incomplete penetrance
Explanation:
In genetics, variable expressivity refers to the fact that individuals having the same alleles/genes/genotype associated with a particular genetic condition may exhibit different clinical features of this condition. In general, variable expressivity is due to the combination of both genetic and environmental factors. An example of variable expressivity is the Marfan syndrome, where all individuals with this disorder have a dominant mutation in the FBN1 (fibrillin 1) gene and show different degrees of the same phenotype. Moreover, incomplete penetrance (also known as reduced penetrance) refers to the complete absence of a genetic trait or disease in individuals having alleles/genes/genotype associated with the condition. In consequence, individuals with incomplete penetrance do not develop features of the disease. An example of incomplete penetrance is given by those individuals with mutations in BRCA1/BRCA2 genes (associated with an increased risk of developing breast cancer) that do not develop cancer.

5. Shawn has a hypothesis that fungicides harm bee development. Using what you now know, describe an experiment to test Shawn’s hypothesis. Be sure your response includes what data should be collected and how you would collect it.
Answer:
Yes.
Explanation:
Yes, the fungicides harm bee development by causing changes in behavior, immune health, and reproduction etc. For verifying this hypothesis, we have to take two environments, in one environment fungicides are applied to the plants while on the other environment, there is no fungicide applied to the plants. Th result shows that the bees are affected and act abnormal where fungicides are applied as compared to those bees which are normal in behaviour and other features.
What are three techniques that can be used to show that the electron transport chain is found on the matrix side of the inner mitochondrial membrane. Select all that apply.
Answer:
Explanation:
Step 1: Generating a Proton Motive Force
The hydrogen carriers (NADH and FADH2) are oxidised and release high energy electrons and protons
The electrons are transferred to the electron transport chain, which consists of several transmembrane carrier proteins
As electrons pass through the chain, they lose energy – which is used by the chain to pump protons (H+ ions) from the matrix
The accumulation of H+ ions within the intermembrane space creates an electrochemical gradient (or a proton motive force)
Step Two: ATP Synthesis via Chemiosmosis
The proton motive force will cause H+ ions to move down their electrochemical gradient and diffuse back into matrix
This diffusion of protons is called chemiosmosis and is facilitated by the transmembrane enzyme ATP synthase
As the H+ ions move through ATP synthase they trigger the molecular rotation of the enzyme, synthesising ATP
Step Three: Reduction of Oxygen
In order for the electron transport chain to continue functioning, the de-energised electrons must be removed
Oxygen acts as the final electron acceptor, removing the de-energised electrons to prevent the chain from becoming blocked
Oxygen also binds with free protons in the matrix to form water – removing matrix protons maintains the hydrogen gradient
In the absence of oxygen, hydrogen carriers cannot transfer energised electrons to the chain and ATP production is halted

Sickle cell anemia in the United States disproportionately affects African Americans; 1 in 700 African Americans are affected by sickle cell anemia, while only 1 in 160,000 Americans of European descent are affected. The absolute risk of a newborn African American child having sickle cell anemia is ____________%, and the relative risk compared to a newborn European American child is ____________-fold
Answer:
0.0014; 0.0044
Explanation:
The absolute risk (AR) of a disease refers to the risk of developing the disease over a given time period. In this case, the absolute risk of the newborn African American child having sickle cell anemia is equal to 1 individual with the disease over 700 individuals >> AR = 1 / 700 = 0.0014. Moreover, the Relative Risk (RR) is calculated by comparing the likelihood of the absolute risk occurring between two distinct groups. In this case, the relative risk for the newborn African American having sickle cell anemia compared to a newborn European American child can be calculated by dividing the absolute risk of the newborn European American child with the measured absolute risk of the newborn African American child >> RR = 0.0000625 / 0.0014 = 0.0044.
QUESTION 16 Why does spoiled food become more sour? Spoilage microbes produce acid The nutrients in juice react with its packaging More hydrogen ion is consumed by spoilage microbes Enzymes in juice generate more hydroxide
Answer:
Spoilage microbes produce acid
Explanation:
When food becomes spoiled or is unprotected, bacteria will invade the food. These types of bacteria are called spoilage bacteria. The bacteria will multiply by consuming the nutrients from the food and grows very rapidly. In certain conditions, the invading bacteria will produce acids that protects them and creates a barrier for other microbes. This acid is what gives spoiled food a sour taste.
