Which hormone is essential to our ability to maintain our fluid levels? Which hormone is essential to our ability to maintain our fluid levels? cortisol thyroxine insulin aldosterone

Answers

Answer 1
Answer:

Answer:

Aldosterone.

Explanation:

Aldosterone is a hormone that regulates the levels of sodium and potassium in our body, which leads to regulate our fluid levels.

In order to increase the fluids in our system, aldosterone causes the absorption of sodium from our kidneys. The kidneys are the place where our body filters the blood absorbing what it needs, such as sodium, and excreting the rest as urine. With the entering of sodium to our bloodstream, water also enters, increasing the volume of blood in our body.

Aldosterone is also responsible for the excretion of potassium into the urine, controlling the levels of this ion, which is extremely important for a high number of reactions.

"Platyhelminthes" exhibit: a. Radial symmetry and no cephalization b. Bilateral symmetry and no cephalization c. Radial symmetry and cephalization d. Bilateral symmetry and cephalization e. none of the above

Answers

Answer:

The correct answer is option b. "Bilateral symmetry and no cephalization".

Explanation:

"Platyhelminthes" are a type of flatworms that lack circulatory and respiratory organs, and have an unique digestive cavity. Two characteristics that define platyhelminthes are they have bilateral symmetry and no cephalization. Bilateral symmetry means that if you draw a line from the head to the tail of the flatworm, you will obtain two mirror sides. Regarding cephalization, platyhelminthes are considered not fully cephalized as they only have the beginnings of cephalization.

The formula F = ma shows the relationship between force, mass, and acceleration. Solve this formula for a.A. a = F + m
B. a = F – m
C. a = Fm
D. a = F divided by m

Answers

The answer is D. This means that is you have a determined amount of force (in newtons) being applied on an object of known mass (in kilograms), then to determine the acceleration of the object, divide the force by the mass (or multiplying the force with the inverse of the mass of the object). This behavior of objects is stipulated in Newtons/ second law. Increasing the force increases the acceleration while increasing the mass decreases the acceleration of the object. Acceleration is a vector quantity meaning it has magnitude and direction.

F=ma => a=F/m
The answer to your question is D. I hope this is the answer that you are looking for and it comes to your help.
