Answer:
Explanation:The phospholipid bilayer formed by these interactions makes a good barrier between the interior and exterior of the cell, because water and other polar or charged substances cannot easily cross the hydrophobic core of the membrane. Can water cross the plasma membrane at all?
It also helps the cell move things in and out. The cell membrane is made of what is called a phospholipid bilayer, which means it has two layers of phospholipids. ... This allows the phosphates to be exposed to water, either in the cell or the environment, while the lipids are protected from water Lipids are essential for all life on Earth. They play many important roles in maintaining the health of an organism. Arguably the most important function lipids perform is as the building blocks of cellular membranes. Other functions include energy storage, insulation, cellular communication and protection.Large quantities of water molecules constantly move across cell membranes by simple diffusion, often facilitated by movement through membrane proteins, including aquaporins. In general, net movement of water into or out of cells is negligible.

The New Orleans Musicians' Clinic did not make any recommendations about low or high pitch sounds. Why are high pitch sounds less damaging to ears than louder sounds? Use your model and what you have learned about sound waves and energy to write an explanation. Some helpful words to include in your response are: transfer, energy, eardrum, and air particles.
Answer:
Due to high energy.
Explanation:
High pitch sounds less damaging to ears than louder sounds because louder sounds contains more energy than high pitch sound. When this high energy of loud sound transfer from air particles towards our eardrum, it can greatly damaged the ear while on the other hand, high pitch sound has low energy so it causes less damaged to the eardrum.

Explanation:
Can two different species of fungi from two different genus' mutate into a new species? i just want to know if it's a possibility, and how gigantic or slim the chances are of it happening.
Answer:
Yes, it is possible.
Explanation:
In this case, I'm guessing you mean breeding.
If that's the case, they will form hybrids.
Between two different species, inter specific hybrids will be formed.
Between two different genus, intergeneric hybrids will be formed.
There's even rare cases of breeding between two families.
So while it is possible for different species and/or genus to breed and form new species, in interspecific breeding for instance, they will have features similar to the parents but turn out sterile.
So to answer your question, it is possible.

How is antibiotic resistance related to natural selection?
Answer:
Antibiotic resistance is a consequence of evolution via natural selection. The antibiotic action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce. They will then pass this trait to their offspring, which will be a fully resistant generation.

A major function of the human urinary bladder is
A) storing urine until it is eliminated
B) releasing urine directly into the bloodstream
C) transforming urine into a nitrogenous waste
D) filtering urine out of the blood
Answer:
A) storing urine until it is eliminated
Explanation:
CORRECT
Assume that (B) is dominant and (b) is recessive: Bb mates with Bb
A. About 50% of the offspring will show the recessive trait
B. All the offspring will show the dominant trait
C. All the offspring will show the recessive trait
D. About 75% of the offspring will show the dominant trait
If B is dominant over b and Bb mates with Bb, about 75% of the offspring will show the dominant trait.
Looking at the cross:
Bb x Bb
BB Bb Bb bb
BB and Bb will show the dominant trait while only bb will show the recessive trait.
Thus, the chances of the offspring showing the dominant trait would be 3/4 or 75% while the chances of showing the recessive trait would be 1/4 or 25%

Does the distance from earth to sun determine the seasons? please explain
Answer:
nope
Explanation:
Contrary to popular belief, the seasons are not determined by the earth's distance from the sun. The seasons are actually caused by the earth's tilted axis. Because the axis is tilted, when the Northern Hemisphere is tilted towards the sun, it's warm.

4. What best describes the role of mutations in evolution?
a. Mutations are not necessary for evolution because they are not herita
b. Mutations are useful for evolution to occur because they promote ger
uniformity within a population.
c. Mutations are essential for evolution to occur because they produce
variations within a population.
d. Mutations are essential for evolution to occur because they are respo
environmental changes.
Answer: option C.
Mutations are essential for evolution to occur because they produce variations within a population.
Explanation:
This is because Mutation refer to change in the genetic content or DNA composition of organisms. Therefore , for evolution to occur there must be Mutation because it is the main source of genetic variation or causes genetic variation needed for evolution.
Mutation is important as the basics of evolution because it produce a new DNA sequence for a gene function, which lead to the formation of new allele.

Why do we need friction in our world?
Friction is a force that works against motion. While walking, friction helps us maintain our stability and prevents us from slipping. Friction also works the same way with cars and vehicles in general, preventing them from skidding and helping them stop when the brakes are applied. We also need friction to make a fire.
Without friction between the shoes and the ground, you cannot walk properly. If there is no friction, all of us would be sliding around without any control over ourselves. While walking, you're pushing your foot back as you try to step forward. Friction holds your shoe to the ground so you can walk around.
