plz help!!! Gall flies lay their eggs in developing shoots of the tall goldenrod. When the fly larvae hatch, they release chemicals that cause the plant tissue to swell around the larvae, causing a resultant gall to form. The gall flies are prey for the parasitic wasp that lays its eggs in the smallest galls. After the wasp larvae hatch, they eat the fly larvae. The gall fly is also prey for the downy woodpeckers that feed on the larvae of the largest galls. Which type of natural selection may the gall fly be subject to?
Directional selection
Disruptive selection
Normal distribution
Stabilizing selection
im so confused
Answer:
stabilizina selection
Explanation:
As given in the question, the galls may be smaller or larger. However the eggs laid in smaller gallsare prey to wasps, hence they are destroyed

Which of the following would be the best definition of diffusion? The movement of molecules....
- from an area of higher concentration to an area of lower concentration
-using energy
-down the concentration gradient
-from an area of lower concentration to an area of higher concentration
-using energy
-up a concentration gradient
-from an area of low concentration to an area of high concentration
- without energy
- up the concentration gradient
-from an area of higher concentration to an area of lower concentration
-without energy
-down the concentration gradient
Answer:
-from an area of higher concentration to an area of lower concentration
-without energy
-down the concentration gradient
Explanation:
Simple diffusion does not require energy. This is likely what the question is referring to.
An example of simple diffusion:
If you blow up a balloon and then poke a small hole in it. The air will leak out from the high concentration inside the balloon to the low concentration outside of the balloon. It does not require any energy to be put it--it leaks out on its own as long as there is a hole.
Answer:
-from an area of low concentration to an area of high concentration
- without energy
- down the concentration gradient
Explanation:
The movement of molecules from an area of low concentration to an area of high concentration, without energy, down the concentration gradient is correct.

If a horse has 40 chromosomes in its heart cells there will be blank chromosomes in its tail cells and blank chromosomes in its egg cells
Answer:
40 in tail and 20 in egg cells.
Explanation:
If a horse has 40 chromosomes in its heart cells so there will be 40 number of chromosomes in its tail cells and 20 number of chromosomes in its egg cells because tail is also a part of body where mitosis type of cell division occurs means there is diploid number of chromosomes, while on the other hand, egg cells are the reproductive part where meiosis type of cell division occur in which haploid number of chromosomes are present.

Although sound can be heard, it is not
considered to be matter. Which of the
following best explains this?
A. Sound cannot be captured for analysis by scientists.
B. Sound exhibits qualities of both energy and matter.
C. Sound cannot be measured.
D. Sound does not have mass nor does it take up space.
Answer:
D
Explanation:
all the others dont make sense
In contrast to other sounds, the sound is the movement of a pressure wave across a medium of particles. Being a wave, it is not regarded as a kind of substance, hence option D is correct.
What are the characteristics of sound?Because the molecules of a solid are closer together and can transfer vibrations more quickly, sound passes through solids more swiftly than through liquids and gases.
Since gas molecules are the farthest apart, sound moves through them at the slowest speed, it instructs the mind to decipher the incoming sound.
The energy comes from an outside source, such as singing or drumming. It may also be viewed as the vibrations moving through the material world.
Therefore, the physical vibration waves that pass through the air to reach the ears are referred to as sound energy, hence option D is correct.
