# The antidepressant fluoxetine (or Prozac) has a half-life of about days. What percentage of a dose remains in the body after one day?

The complete question is :

The antidepressant fluoxetine (or Prozac) has a half-life of about 3 days. What

percentage of a dose remains in the body after one day

Explanation:

Half life of a substance can be defined as the amount of time taken to degrade it half or it can be defined as the time which is required by the substance to become half of its original amount.

Here we need to find the half life of a medicine fluoxetine.

The equation which can be written for the question is :P(t) which will provide the information about the amount of medicine left in the body after one day or time (t)

Since the half-life is 3 days, P(t) = 2−t/3.

Then P(1) = 2−1/3 ≈ 0.794 =  0.794*100=79.4%  is the amount of substance left in the body after one day.

Lymphatic organ that removes pathogens by filtering blood is the a. lymph node
b. spleen
c. thymus
d. tonsil
e. thyroid

Explanation:

The lymphatic system of the body works by filtering the blood and remove the harmful pathogen that is present in it.

There are several organs in the lymphatic system that works together at different sites in the body and helps body prevent and cure from infection.

Lymph nodes function to remove pathogen and debris from lymph and it is also referred as filters of lymph. The macrophages and dentritic cells kill the harmful pathogen in the blood.

Hence, the correct answer is option A

According to the escience lab manual for lab 1, experiment 3, you need to prepare a 47 mL of a 24% soda/syrup prescription. To do this, you can use the 80% syrup solution and the 10% soda solution that you have in stock. How many mLs of soda solution do you need to create this final solution?

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 = V₂c₂

Data:

V₁ = ?;          c₁ = 80 %

V₂ = 47 mL; c₂ = 24 %

Calculations:

1. The volume of stock syrup

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.

Which of the following is/are activated by an increase in mean arterial pressure (MAP) to 120 mmHg? a. Myogenic autoregulation only
b. Tubuloglomerular feedback only
c. Both myogenic autoregulation and tubuloglomerular feedback
d. Neither myogenic autoregulation or tubuloglomerular feedback

Both myogenic autoregulation and tubuloglomerular feedback  are activated by an increase in mean arterial pressure (MAP) to 120 mmHg?

Explanation:

Mean arterial pressure is the average blood pressure an individual has during a single cardiac cycle. It is considered normal when it is between 65 to 110 mmHg.

When there is an increase in MAP to 120 mmHg then the myogenic autoregulation helps in protecting the glomerular capillaries against the rapid elevation during arterial pressure. Whereas, tubuloglomerular feedback is involved in controlling the RBF and GFR has a response to sustained reduction MAP.

When there is an increase in mean arterial pressure (MAP) to 120 mmHg, both myogenic autoregulation and tubuloglomerular feedback are activated.

Explanation:

Myogenic autoregulation is the reflexive action which constricts the stretched smooth muscles in the blood vessels like arteries and arterioles when there is an increase in MAP.

Tubuloglomerular feedback is a mechanism which corrects the glomerular filtration rate based on the salt concentration in the renal tubules.

Both myogenic autoregulation (of preglomerular arterioles) and tubuloglomerular feedback (TGF) are the homeostatic mechanism used for autoregulation of renal blood flow (ARBF) and prevent renal arterial pressure elevation.

ARBF takes place which constricts the renal arterioles according to their salt content. TGF then acts along with myogenic autoregulation to control the elevation of MAP and renal arterial blood flow.
