In a population of fruit flies grown in laboratory conditions, a new phenotype arises. Instead of the typical red eyes, a purple

-eyed
individual is seen. This individual survives to adulthood and is able to mate with other flies. Two students studying the fruit fly
population discuss the origin of the purple-eyed fruit fly. One student insists that the fly came from outside of the original fruit fly
population. The other student claims that the fly originated from within the laboratory fruit fly population. Which statements defend
the claim of student two that the new phenotype originated from within the fruit fly population?

Answer:

Option B

Explanation:

Complete question -

Following their sixteen-week, closed-ended, grief and loss psychotherapy group with adults as reported by Price et al, which of Yalom's therapeutic factors was most identifiable?

a. recapitulation

b. altruism

c. universality

d. imagery

Solutions -

Out of the eleven therapeutic factors the one that will be easily recognizable will be the one which will involve some kind of action and interaction or any visible signs. Altruism would affect a person positively and help him/her to gain confidence. This confidence will be visible by the person’s action when he/she will help other people in the group to gain value and significance in the same way as he/she has done.  

Hence, option B is correct

a laptop power changer has an output of 5.00 V ang has a resistance of 800 ohms. what is the current output of the charger?​
DochEvi [55]

Answer:

The correct answer is - 6.25 mAh.

Explanation:

According to the Ohms law of power, the current of a source can be found with the help of the formula

I = V ÷ R

where, I (amps) = V (volts) ÷ R (Ω)

By placing the value given:

I = 5.00/800

I = 6.25 mAh

The current output of the charger would be 6.25 mAh

What drives the process of plate tectonics, the currently accepted explanation for the movement of drifting continents?
Elena-2011 [213]
<span>There is heat from the Earth’s core. Unfortunately, even thought the Earth is round, this heat isn’t evenly distributed. Therefore, sometimes the pressure from the heat in some areas can create currents that move the plates across the Earth’s surface.</span>

Which type of natural selection occurs when an intermediate phenotype is favored?
klasskru [66]

Answer:

The type of natural selection that occur when intermediate phenotype is favored is called STABILIZING SELECTION.

Explanation:

There are 3 major types of natural selection, these are: stabilizing, directional and diversifying selection.

A stabilizing selection is said to occur when natural selection favors average phenotype by selecting against extreme variations. Stabilizing selection usually leads to decrease in genetic variation of the population concerned.

A good example of stabilizing selection is that of snakes, which have deep green color that blend completely with their environment. This set of snakes will escape from predators more than others in the population, which have color that slightly differ from deep green and which do not blend very well with the environment. Those snakes, whose colour do not blend very well with their environment will get killed more easily by the predators and with time will become extinct while those with colour that blend with the enviroment will survive and produce more offspring.

The extinction of snakes from the population will lead to decrease in genetic variation.

If an object has 100 joules of potential energy at the top of a ramp. How much kinetic energy will there be at the other two pla
ruslelena [56]

Answer:

As the diagram for the question is not given, lets answer the question generally.

Explanation:

Energy in a system is neither created nor destroyed. Yet, the energy can be changed from one form to another. If in the beginning, at a point a,  an object has a potential energy of 100 joules, then at point b the kinetic energy of the object will be subtracted from the total  100 joules of energy present in the beginning. This is because the potential energy will be being changed to the kinetic energy and no new energy will be created or destroyed.
