Answer:

The correct answer is D.

Explanation:

Papillary muscles, attached via chordae tendineae, help to close the valves and prevent regurgitation.

Pectinate muscles are parallel ridges in the walls of the atrium of the heart, mainly in right atrium. They can stretch during adverse loading conditions, to <em>help the right atrium to dilate without much wall stres</em>s.

Staff-directed is the  stage of the culture change continuum are meals served buffet-style at specified time ranges and is denoted as option A.

<h3>What is a Buffet?</h3>

This is defined as a system in which foods are placed in public and individuals are allowed to serve themselves. Food contain different types of nutrients which are important for the growth and survival of organisms which are present in the ecosystem.

Examples of food include the following:

  • Carbohydrate
  • Protein
  • Fat and oil etc

In the case of culture change continuum where meals are served buffet-style at specified time ranges, it is usually staff directed.

n this example we will use the concept of equivalent resistance to determine the current in a circuit. Three identical resistors
belka [17]

Answer:

The answer is below

Explanation:

The complete question is in the iimage attached.

a) We can see that R1 is in series with the parallel combination of R2 and R3. Hence the equivalent resistance is given by:

R_{eq}=R_1+(R_2//R_3)\\\\R_{eq}=R_1+\frac{R_2R_3}{R_2+R_3}\\ \\R_{eq}=6+\frac{6*6}{6+6}\\\\R_{eq}=6+3\\\\R_{eq}=9\ \Omega

b)

The current in the circuit (I) is given as:

I = emf / Req

I = 18 / 9

I = 2A

The current through resistor R1 = I1 = I = 2A

Since R2 and R3 are parallel to each other their respective currents I2 and I3 is given  as:

I_2=I*\frac{R_3}{R_2+R_3}=2*\frac{6}{6+6}=1\ A  \\\\I_3=I*\frac{R_2}{R_2+R_3}=2*\frac{6}{6+6}=1\ A

A cell or an organ that responds to commands of the control center in negative feedback is termed a(n)
love history [14]

Answer:

Option a. effector

Explanation:

Effectors acts in response to the commands of the control center in negative feedback.

Negative feedback is when the system responds to the stimulus in such that  it reverses the direction in which change occurs thus maintaining homeostatis (stability).

An example of negative feedback is thermoregulation in which body temperature is regulated with skin acting as receptor to communicate information to control center (brain); sweat glands and  blood vessels acting as effector which results in regulation of body temperature.

The Effectors either supports or opposes the stimulus.

Which reason is appropriate to take a child that underwent a submersion injury immediately to the hospital
ExtremeBDS [4]

A child who underwent submersion injury needs to be taken to a hospital because the child can suffer from <u>hypoxia, damage to neurons, pulmonary edema, further complications</u>, etc.

Submersion Injury

Submersion injury occurs when the person who is submerged in a liquid aspirates the liquid or has laryngospasm that occurs without the aspiration of the liquid. The former was previously called wet drowning and the latter was called dry drowning. The person must be removed from the liquid as fast as possible and 1st aid must be given after which the person must be taken to the hospital for further treatment.

A child who underwent submersion injury needs to be admitted to a hospital as various complications such as edema, respiratory compromise, hypoxia, etc. Hypoxia can lead to severe damage to various cells including neurons and other cells in the body. Submersion injury also results in the reflex inspiration that can lead to pulmonary edema.

Note: - The question seems incomplete and the missing options could be

  1. "Hypoxia can cause global cell damage.
  2. Neurons often sustain irreversible damage.
  3. Complications can occur even after 24 hours.
  4. Fluid absorption in the pulmonary circulation causes pulmonary edema."
