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.

Answers

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.

Photosynthesis converts ______________________ and ___________________ into food-energy molecule ______________________ and gives off ____________
if the answer is outrageously incorrect you will be reported

Answers

Answer:

Photosynthesis converts Light and chemical energy in to food-energy molecule sugar and gives off Oxygen

Explanation:

6CO2 + 6H2O → C6H12O6 + 6O2

Photosynthesis is a chemical reaction that takes place inside a plant, producing food for the plant to survive.

Carbon dioxide, water and light are all needed for photosynthesis to take place.

Photosynthesis happens in the leaves of a plant.

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.

Answers

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.

Answers

Stage One: Autolysis

The first stage of human decomposition is called autolysis, or self-digestion, and begins immediately after death. As soon as blood circulation and respiration stop, the body has no way of getting oxygen or removing wastes. Excess carbon dioxide causes an acidic environment, causing membranes in cells to rupture. The membranes release enzymes that begin eating the cells from the inside out.

Rigor mortis causes muscle stiffening. Small blisters filled with nutrient-rich fluid begin appearing on internal organs and the skin’s surface. The body will appear to have a sheen due to ruptured blisters, and the skin’s top layer will begin to loosen.

Stage Two: Bloat

Leaked enzymes from the first stage begin producing many gases. The sulfur-containing compounds that the bacteria release also cause skin discoloration. Due to the gases, the human body can double in size. In addition, insect activity can be present.

The microorganisms and bacteria produce extremely unpleasant odors called putrefaction. These odors often alert others that a person has died, and can linger long after a body has been removed.

Stage Three: Active Decay

Fluids released through orifices indicate the beginning of active decay. Organs, muscles, and skin become liquefied. When all of the body’s soft tissue decomposes, hair, bones, cartilage, and other byproducts of decay remain. The cadaver loses the most mass during this stage.

Stage Four: Skeletonization

Because the skeleton has a decomposition rate based on the loss of organic (collagen) and inorganic components, there is no set timeframe when skeletonization occurs.

plz help. what does Archaeopteryx prove about modern birds?​

Answers

Answer:

It appears that Archaeopteryx had the brain structures and inner-ear balance sensors that birds use to control their flight. Archaeopteryx also had a wing feather arrangement like that of modern birds and similarly asymmetrical flight feathers on its wings and tail.

It is one of the most important fossils ever discovered. Unlike all living birds, Archaeopteryx had a full set of teeth, a rather flat sternum ("breastbone"), a long, bony tail, gastralia ("belly ribs"), and three claws on the wing which could have still been used to grasp prey (or maybe trees).

What type of mutation is shown in the DNA strand to the right given the original strand.



original - T A T G A C A A T ---> mutated strand - T A T C A C A A T

Group of answer choices

point mutation

deletion

insertion

translocation

Answers

the answer is insertion
Correct answer - Point mutation.

Why? - A point mutation or substitution is a genetic mutation where a SINGLE nucleotide base is changed, inserted or deleted from a DNA or RNA sequence of an organism's genome.

Why not Insertion - In genetics, an insertion (also called an insertion mutation) is the addition of one or more nucleotide base pairs into a DNA sequence. This can often happen in microsatellite regions due to the DNA polymerase slipping. ... On a chromosome level, an insertion refers to the insertion of a larger sequence into a chromosome. So, in short Insertion adds one nucleotide but not changes one nucleotide to another. Which is done by POINT MUTATION.

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

Answers

All the offspring will show the recessive 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%

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.

The Cell Wall of Bacteria

Key Points

A cell wall is a layer located outside the cell membrane found in plants, fungi, bacteria, algae, and archaea.

A peptidoglycan cell wall composed of disaccharides and amino acids gives bacteria structural support.

The bacterial cell wall is often a target for antibiotic treatment.

Bacterial Cell Wall: The anatomy of bacterial cell structure.

Bacterial cells lack a membrane bound nucleus. Their genetic material is naked within the cytoplasm. Ribosomes are their only type of organelle. The term “nucleoid” refers to the region of the cytoplasm where chromosomal DNA is located, usually a singular, circular chromosome. Bacteria are usually single-celled, except when they exist in colonies. These ancestral cells reproduce by means of binary fission, duplicating their genetic material and then essentially splitting to form two daughter cells identical to the parent. A wall located outside the cell membrane provides the cell support, and protection against mechanical stress or damage from osmotic rupture and lysis. The major component of the bacterial cell wall is peptidoglycan or murein. This rigid structure of peptidoglycan, specific only to prokaryotes, gives the cell shape and surrounds the cytoplasmic membrane. Peptidoglycan is a huge polymer of disaccharides (glycan) cross-linked by short chains of identical amino acids (peptides) monomers. The backbone of the peptidoglycan molecule is composed of two derivatives of glucose: N-acetylglucosamine (NAG) and N-acetlymuramic acid (NAM) with a pentapeptide coming off NAM and varying slightly among bacteria. The NAG and NAM strands are synthesized in the cytosol of the bacteria. They are connected by inter-peptide bridges. They are transported across the cytoplasmic membrane by a carrier molecule called bactoprenol. From the peptidoglycan inwards all bacterial cells are very similar. Going further out, the bacterial world divides into two major classes: Gram positive (Gram +) and Gram negative (Gram -). The cell wall provides important ligands for adherence and receptor sites for viruses or antibiotics.
