Answer:
33 mL
Explanation:
It is important to recognize that the total amount of pure syrup remains constant:
Total syrup in the stock solution = total syrup in dilute solution
Thus, we can use the dilution formula
V₁c₁ = V₂ c₂
Data:
V₁ = ?; c₁ = 80 %
V₂ = 47 mL; c₂ = 24 %
Calculations:
1. The volume of stock syrup
[tex]\begin{array}{rcl}V_{1}c_{1} & = & V_{2}c_{2}\\V_{1}\times80 \, \% & = & \text{47 mL}\times 24 \, \%\\80V_{1} & = & \text{1130 mL}\\V_{2}&=& \dfrac{\text{1130 mL}}{80}\\\\&=&\text{14 mL}\\\end{array}\\\text{You need $\textbf{14 mL}$ of stock syrup.}[/tex]
2. The volume of soda solution
Total volume of dilute solution = 47 mL
The volume of stock syrup = 14
Volume of soda solution = 33 mL
You need 33 mL of soda solution.
For a particular disease at a specific time period, morbidity rates should always be equal or greater than mortality rate.
a. true
b. false
Answer:
A. True
Explanation:
Morbidity involves the condition of having a disease while mortality is the condition of being deceased(dead).
For a particular disease at a specific time period, morbidity rates should always be equal or greater than mortality rate. This will ensure all the species affected by the disease aren’t wiped out in an instant as every organisms have different roles to play in the ecosystem.
If all glucose is normally reabsorbed in the proximal tubule of the nephron, why do people with diabetes have glucose in their urine
Answer:
People have glucose in their urine because they reach very high glucose values, that is, glycemic peaks.
Glycemic peaks occur due to a functional lack of the hormone insulin, insulin in this pathology is altered or absent, that is why the cells cannot assimilate energy and glucose does not enter the intracellular medium.
When glycemia reaches very high values, it is secreted by urine, but not all glucose is secreted, that is why high concentrations of glucose will be found in plasma and urine, this is called glycemia or uremia in the case of urine.
Diabetes disease is discovered by laboratory tests and clinical signs, the most frequent are: high blood glucose, glycosylated hemoglobin, uremia, high concentration of ketone bodies or ketoacidosis, ketone breath, alteration of the cardiovascular system, high cholesterol, weakness or fatigue, spontaneous diarrhea, among others.
Explanation:
The nephron is the glomerular filtration unit, in which a filtering of the body's waste takes place, through channels or diffusion waves, these channels or these diffusion mechanisms, some are non-saturable and others are saturated in the face of extreme concentrations, That is why, in the event of glycemic peaks, the nephron is highly demanded to eliminate glucose, and the mechanism of excision by urine could even be oversaturated.
People who suffer from diabetes can be for various reasons, genetic causes, obesity, ideopathic, autoimmune disorders or even due to genetic failure in the formation of the hormone insulin.
The only effective method to be able to regulate this imbalance and help the nephron to eliminate it correctly is by giving the patient injectable insulin or oral hypoglycemic agents.
The nurse understands that the client who is undergoing induction therapy for leukemia needs additional instruction when the client makes which statement
The question is incomplete as it lacks the group of choices or statements, however the generalized answer is provided on the basis of knowledge.
Answer:
The correct statement would be - "i can not wait to get home to my pet"
Explanation:
Induction therapy affects the WBC of the patient as it destroys during the therapy which leaves them prone for infection and risk of bleeding tendencies.
Pets like dog or cat contains infection which is dangerous for such patient as there is very low production of new platelets and WBC so one should avoid the contact with the animals or people with cold or cough.
Thus, the correct answer would be - "i can not wait to get home to my pet"

Which is the correct path of an electrical excitation from the pacemaker to a cardiomyocyte in the left ventricle (LV)?
Answer:
The question is lacking the options, below is the completely stated question and options:
This is the correct path of an electrical excitation from the pacemaker to a cardiocyte in the left ventricle (LV).
A. sinoatrial (SA) node → atrioventricular (AV) node → atrioventricular (AV) bundle → Purkinje fibers → cardiocyte in LV
B. atrioventricular (AV) node → sinoatrial (SA) node → atrioventricular (AV) bundle → Purkinje fibers → cardiocyte in LV
C. sinoatrial (SA) node → atrioventricular (AV) bundle → atrioventricular (AV) node → Purkinje fibers → cardiocyte in LV
D. atrioventricular (AV) node → Purkinje fibers → atrioventricular (AV) bundle → sinoatrial (SA) node → cardiocyte in LV
E. sinoatrial (SA) node → atrioventricular (AV) node → Purkinje fibers → atrioventricular (AV) bundle → cardiocyte in LV
Answer:
The correct answer is:
sinoatrial (SA) node → atrioventricular (AV) node → atrioventricular (AV) bundle → Purkinje fibers → cardiocyte in LV (A.)
Explanation:
The electrical impulse conduction system of the heart refers to the pathways through which electrical signals pass, to cause excitation of specific paths of the heart, leading to depolarization, which in turn leads to contraction and relaxation of the heart. The correct excitation pathway is as follows:
1. Normal excitation originates in the sinoatrial (SA) node, from which depolarization spreads throughout the atria, causing impulses (excitation) to spread from the SA node to the atria. It is believed that this depolarization spreads to the atrial cells through adjacent myocardial cells and myofibrils.
2. Next, the depolarization from the atria reaches the atrioventricular (AV) node, causing excitation of the AV node. The AV node is located on the floor of the right ventricle, close to the interventricular septum. The excitation leaves this site by two pathways; the fast and slow pathways which vary based on the time of transmission of impulses to the next phase.
3. Next, from the AV node, the excitation is passed to the two branches of the bundle of His, which form a network of fibers known as purkinje fibers, from where excitation passes to the apical region of the left and right ventricles causing depolarization of the ventricular myocardium.
Attached to this answer is a picture to show what the pathway looks like.
The correct path of an electrical excitation from the pacemaker to a cardiomyocyte is:
sinoatrial (SA) node → atrioventricular (AV) node → atrioventricular (AV) bundle → Subendothelial conducting network → cardiomyocyte in LV.
The heart is a cone-shaped hollow muscular organ that possesses the property of generating its own electrical impulses or excitations.
It is divided into four(4) chambers namely the right ventricle, left ventricle, right atrium and left atrium.
The correct path of an electrical excitation is from:
The pacemaker: This is also called the sinoatrial (SA) node. It generates the electrical excitations.Atrioventricular (AV) node: The electrical excitation initiated by SA node is then transmitted to AV node. This transmits the signal from atria to ventricles.Atrioventricular (AV) bundle: These are specialised fibres that originate from the AV node. They are the bundle that divides to form the right and left bundle branches.Subendothelial conducting network: This is also called the Purkinje fibres which is formed within the ventricular myocardium.Cardiomyocyte of the left ventricle: The cardiomyocytes are set of cells that generates contractile force in the heart. These are located at the left ventricle.Therefore, the correct path of an electrical excitation from the pacemaker to a cardiomyocyte is:
sinoatrial (SA) node → atrioventricular (AV) node → atrioventricular (AV) bundle → Subendothelial conducting network → cardiomyocyte in LV.

1. Asthma is a restrictive lung disorder that causes constriction and congestion of the pulmonary bronchioles. How would an asthma attack affect FVC
Answer:
by hyperinflation of lungs
Explanation:
Asthma is a disease of the lungs caused by inflammation and narrowing of the airways, thereby difficulting breath. Severe asthma disorders are associated with a significant decrease in the rate of maximal expiratory airflow and the reduction in the total volume expired, which is a value known as Forced Vital Capacity (FVC). In consequence, severe asthma events are correlated with the hyperinflation of the lungs and thus be a possible cause for the observed reduction in the FVC.

Question 6 options:
reposition the legs during flight only slightly faster than average sprinters
hit the ground harder than average sprinters
apply GRF faster than average sprinters
All of the above are correct
Answer:
reposition the legs during flight only slightly faster than average sprinters
Explanation:
The main difference between elite sprinters and average sprinters is the ability of elite sprinters to make longer, more impactful strides. This allows them to have a greater boost.
This boost is a result of the muscle fibers in your legs, which allow them to make strides that have little contact with the ground, but propel them forward faster than average sprinters. In short, elite sprinters are able to reposition their legs during flight just a little faster than the average sprinter.
