Answer:
2.glucose move into chamber B faster than fructose
Explanation:
- Facilitated diffusion: refers to the transport of hydrophilic molecules that are not able to freely cross the membrane. Channel protein and many carrier proteins are in charge of this <u>passive transport</u>. If uncharged molecules need to be carried <u>this process depends on concentration gradients</u> and molecules are transported from a higher concentration side to a lower concentration side. If ions need to be transported this process depends on an electrochemical gradient. The glucose is an example of a hydrophilic protein that gets into the cell by facilitated diffusion. Facilitated diffusion is a passive transport process because the cell does not need any energy to make it happen.
The exposed scenario is an example of facilitated diffusion, a process that occurs in favor of the concentration gradient, and which rate depends on the concentration of molecules in each side of the membrane, in this case, glucose and fructose, among other factors that might also influence the diffusion rate. So, as the concentration of glucose is higher in chamber A (80%), and lower in chamber B (20%), in comparison with fructose, the first one will diffuse faster than fructose. The difference in concentration between both chambers is sharper in glucose, so its transport is faster than the fructose transport, which will also diffuse but at a lower rate.
Petri dishes should always be stored inverted.
In biology, petri dishes are frequently used to produce microorganisms like bacteria, yeast, and mold. The organisms that grow on solid or semisolid surfaces are best suited for it. To reduce the chance of contamination from airborne spore particles landing on them and to avoid the buildup of water condensation that could disrupt or impair a culture, they are often covered and stored inverted.
Aside from that, incubating the media in the normal position could result in the media drying out, which would interfere with the ideal conditions for microbial growth and increase microbial count mistakes. Since the labels are put underneath the plates rather than on the lids, placing plates upside down also makes them easier to handle and recognize.

The hair would be curly because if h is recessive and H is just curly, that hair is gonna stay the same.
Answer:
C) convergent evolution
Explanation:
Convergent evolution is a type of pattern of evolution which occurs when the two unrelated species evolves with the same feature or traits as a result of the exposure of the species to the same environmental conditions.
This type of evolution results in ion the formation of the analogous structure which is functionally similar but is evolved from the same ancestor.
In the given question, since the two unrelated species: plants and animals exhibit the same appearance on different geographical areas thus represents that convergent evolution is taking place.
Thus, C) convergent evolution is the correct answer.
