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.

Answer:
Sexual reproduction results in offsrping with genetic variation due to the multiplication brings about limitless prospects of hereditary variety. The examples, that can be studied to support this would be at the end of the day, sexual generation brings about posterity that are hereditarily extraordinary. They vary from the two guardians and furthermore from one another. This happens for various reasons.
Explanation:
Sexual reproduction results in offspring with genetic variation because it involves the fusion of genetic material from two parent organisms, typically a male and a female.
What is genetic variation?Genetic variation refers to the diversity of genetic traits or characteristics within a population or species.
The process introduces genetic diversity through several mechanisms in
Independent Assortment, Crossing Over, Genetic Recombination,
Mutations.
Overall, sexual reproduction promotes genetic variation by combining genetic material from two parents through mechanisms such as independent assortment, crossing over, genetic recombination, and the introduction of new mutations.
This variation is essential for the survival and adaptation of populations to changing environments and plays a fundamental role in evolution.

Cartoon and movie characters such as Wolverine, Mystique and Storm lead to the notion that genetic
mutations always cause profound changes in the phenotype of an organism. However, the lesson
over DNA and Genetics clearly shows that mutations may or may not have an effect. Which of the
following mutations would most likely NOT cause an effect in an organism? (A Codon chart has been
provided below to assist you)
Answer: A
Explanation:
A frameshift mutation is brought on by a single base insertion close to the beginning of the coding sequence.
What is Mutation?Codons are used to express genes in triplets, the insertion will alter the reading frame and provide a translation that is entirely different from the original. Consequently, this will have the greatest detrimental effect.
A mutation is a change to an organism's DNA sequence. Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all cause mutations.
Somatic mutations (which happen in body cells) cannot be passed on to offspring, whereas germline mutations (which happen in eggs and sperm) can.
Therefore, A frameshift mutation is brought on by a single base insertion close to the beginning of the coding sequence.

Explain how photosynthesis provides energy for consumers.
Answer:
Through photosynthesis, certain organisms convert solar energy (sunlight) into chemical energy, which is then used to build carbohydrate molecules. The energy used to hold these molecules together is released when an organism breaks down food. Cells then use this energy to perform work, such as cellular respiration.
Competition is a driving force behind natural selection. Which of these statements best
describes why competition is a constant pressure?
Answer:
The options are not given, here are the options gotten from another website.
A. Organisms produce more offspring than can survive
B. Organisms are taught to fight others of the same species
C. Organisms are taught to fight others of the same species
D. Multiple species fill the same niche and competition will always arise against other species
The correct option is D.
Multiple species fill the same niche and competition will always arise against other species.
Explanation:
This is because competition arises when different organisms living a niche compete for space or resources and this can be as a result of too much population in a niche and limited resources and space. Organisms tend to compete for survival which is the driving force of natural selection.
These u because as competition rises, species tend to develop traits which will help them to survive, adapt , reproduce and compete well in their environment an this result in survival of the fittest....that is those that can adapt well.

Answer: B
Explanation: I did The test
During science class, Mauricio made sketches of the major organelles of the cell. The second sketch describes a mitochondrion. The correct option is B.
What are mitochondria?The “powerhouses” of the cell, mitochondria, break down fuel molecules and harvest energy during cellular respiration. Chloroplasts and mitochondria probably started as microorganisms that were swallowed by larger cells (the endosymbiont theory).
A mitochondrion is a membrane-containing cell organelle. It is the site of energy-producing metabolic processes and cellular respiration. The process happens inside mitochondria.
Thus, the link between cellular respiration and photosynthesis is that the reactant in photosynthesis is a byproduct of cellular respiration.

Explanation:
As animals breathe, they take in O2 (Oxygen) and exhale in CO2 (Carbon Dioxide). This process is called cellular respiration.
Animals use oxygen in the process of cellular respiration to make more carbon dioxide.
What is Cellular respiration?Cellular respiration may be defined as a type of chemical reaction that involves the breakdown of food in the cell with the release of energy in the form of ATP with the help of oxygen and releases carbon dioxide.
The process of cellular respiration is utilized for the derivation of energy by cells in order to accomplish metabolic activities. This process generally occurs in the animal's cells.
The main purpose of this process is to convert foodstuff molecules into the most usable form of chemical energy known as ATP.
It is opposite to the process of photosynthesis in plants that utilized the carbon dioxide from nature and convert it into glucose and oxygen.
Therefore, animals use oxygen in the process of cellular respiration to make more carbon dioxide.
