Answer:
First let's add the missing piece of information for clarity and then the options before we write the answer
The response that the nursing student should make is based on understanding the mechanism of heat loss in the newborn. This nursing intervention is designed to protect the newborn against which heat loss mechanism?
The options:
1. Radiation
2. Convection
3. Conduction
4. Evaporation
The CORRECT ANSWER IS 3.
3. Conduction
Explanation:
Thermoregulation in humans is a major area of homeostasis. In thermoregulation, body heat is produced mainly in the vital organs, such as the liver, brain, and heart, and in skeletal muscles contracting activities.
There are basically four modes of heat loss: convection, conduction, radiation, and evaporation.
Heat loss by radiation and conduction occurs when the skin temperature is higher in comparison to the surroundings temperature.
Heat loss by evaporation occurs when the surroundings temperature is higher in comparison to the skin temperature as in sport activity.
Back to our case study:
1. Radiation❌
Radiation is seen when the body or skin lossses heat to a cooler body without any direct contact being made.
2. Convection❌
Convention is seen when the body or skin losses heat to cooler ambient air.
3. Conduction✔✔✔
Conduction is seen when the body or skin comes in direct contact with a cooler surface resulting in a loss of body heat.
4. Evaporation❌
Evaporation is a phenomenal that results in heat loss in the process of converting liquid to a gas.
The complete question is :
Charlie is investigating friction. She will use the same amount of force to push two wooden balls across two level surfaces. Then she will record her results in the table below.
Which prediction will most likely describe how friction will affect her findings?
Answer:
The distance for Trial 3 will be greater than the distance for Trial 4 because the difference in surface roughness will affect friction.
Explanation:
The frictional force depends greatly on the roughness of the body surfaces. It acts opposite to the direction of motion when two body surfaces have a relative motion between them.
In the context, equal mount of force is applied to push the wooden balls. So the net force which acts on the balls are :
F' = F - f
Here, F = the force applied
f = force of friction
And f = μ.N (N = reaction force)
Here μ is the coefficient of friction that depends on the surface roughness. The frictional force will be less when the surfaces are smooth. Thus for the trails 3 and trial 4, the distance for trail 3 would be greater than trail 4 as the surface is polished and would offer less friction.
The correct answer is A. The phenotype of the F1 generation exhibit all inflated pods since allele P which characterizes inflated pods is the dominant trait. They only carry the allele p which characterizes constricted pods but they will not exhibit the trait. This recessive trait is masked by the presence of the dominant trait.
