3)What is the epiglottis?
4)Why do the walls of the stomach secrete hydrochloric acid?
5)Which TWO parts of the alimentary canal make up the small intestine?
Answer:
3)The epiglottis is a small, movable "lid" just above the larynx that prevents food and drink from entering your windpipe. But if the epiglottis becomes swollen — either from infection or from injury — the airway narrows and may become completely blocked.
4)Your stomach lining also secretes hydrochloric acid, which creates the ideal conditions for the protein-digesting enzymes to work. The potent hydrochloric acid kills bacteria, protecting your body from harmful microbes which can enter your body in food.
5)Made up of three segments -- the duodenum, jejunum, and ileum -- the small intestine is a 22-foot long muscular tube that breaks down food using enzymes released by the pancreas and bile from the liver.

10 POINTS !!! Why is it risky to build something whose natural frequency can be matched by
external vibrations?
Answer:Most objects have at least one natural frequency of vibration. If a nearby object vibrates at the same frequency, it can cause resonance. Resonance is an increase in amplitude of a vibration that occurs when external vibrations match an object's natural frequency.
Explanation:
It is risky to build something whose natural frequency is matched with external vibrations because of ; The effect of resonance
When an object constructed has a natural frequency which is equal to the frequency of a nearby external vibration, the amplitude of the vibration of the object will increase due to the resonance effect which occurs because the external frequency matches up with the natural frequency of the constructed object.
The negative effect of resonance is the increase in the amplitude of the vibration of the object which might lead to the partial or complete collapse of the constructed object.
Hence we can conclude that It is risky to build something whose natural frequency is matched with external vibrations because of ; The effect of resonance

what are the causes of antibiotics resistance ?
Answer:
Over-prescription of antibiotics.
Patients not finishing the entire antibiotic course.
Overuse of antibiotics in livestock and fish farming.
Poor infection control in health care settings.
Poor hygiene and sanitation.
Explanation:
Answer: Antibiotic resistance has become a global threat, and with Antibiotic Awareness Week, it is important to understand the series of events that have led the world to this predicament. Originally touted as a miracle discovery, we are seeing that there can be too much of a good thing.
Explanation: The use of antibiotics has saved millions of lives, but its pervasive use to treat any infection, whether serious, minor, or even viral has lead to the increase in antibiotic resistance. Antibiotics strictly target bacteria, but it is sometimes difficult to differentiate between viral and bacterial infections without costly tests. It is often less time-consuming and more cost effective to proactively prescribe antibiotics, rather than take precautions and prescribe only the correct treatment.
Another issue with antibiotics is the inability to monitor patient intake. Antibiotic dosages are designed to eradicate entire populations of the pathogens. When antibiotics are not taken for the entire prescribed course, pathogenic bacteria can adapt to the presence of low dose antibiotics, and eventually form a population that is completely resistant to the antibiotic regardless of the dosage.
Antibiotic usage is also not exclusive to humans. Every day, antibiotics are used to treat livestock and fish to prevent infections. Similar to overuse in humans, uncontrolled use of antibiotics creates a reservoir of bacteria that could become resistant, thus rendering the antibiotic useless.

What does this process lead to?
Chiasma
Answer: Chiasmata are specialized chromatin structures that link homologous chromosomes together until anaphase I (Figs. 45.1 and 45.10). They form at sites where programmed DNA breaks generated by Spo11 undergo the full recombination pathway to generate crossovers. At a given chiasma, an exchange of genetic material can occur between both chromatids, what is called a chromosomal crossover, but this is much more frequent during meiosis than mitosis. In meiosis, absence of a chiasma generally results in improper chromosomal segregation and aneuploidy.

Answer:
Gas to a car
Explanation:
The ATP function in the cell is equal to the gas or fuel function in the car, as the ATP gives energy to the cell for different functions like the fuel gives energy to the car to move from one place to another.
What is the function of the ATP?
ATP is produced in the cell from the food that living organisms, such as animals and plants, consume and use to produce ATP. There are different reactions that together make ATP, such as glycolysis, the Krebs cycle, and the electron transport chain, and with the help of ATP synthase, ATP is made. It performs a variety of cellular functions, including protein synthesis, food digestion, message transmission from one cell to another, and so on.
Hence, the ATP function in the cell is equal to the gas or fuel function in the car, as the ATP gives energy to the cell for different functions.

Answer:
Surprisingly, yes, the condition is known as supersaturation. At any given temperature and air pressure, a specific maximum amount of water vapor in the air will produce a relative humidity (RH) of 100 percent. Supersaturated air literally contains more water vapor than is needed to cause saturation.

A species of eels that lives in the ocean can move up rivers to spawn. A freshwater pike is unable to move into the ocean from a river. Based on your knowledge of cellular membranes, explain why eels can move back and forth into the ocean, whereas pike cannot.
Answer:
Eels are a long, thin slimy fish that have a fin that runs the entire lengths of the backs of their bodies, extends around the tail and run for a distance on the underside of the fish. They have a wide and strong mouth. The pike has a long, slender body that is olive green in color and fades to yellowish-white on its belly. The reason for this is because they have diffrent bodies and a eel is small while pikes are big and have more weight.

how energy is recycled in an ecosystem. how our atmosphere maintains its temperature. the importance of decomposers in an ecosystem. the one-way flow of energy in an ecosystem.
Answer:
The flow of energy in ecosystems is unidirectional or one-way.
Explanation:
Energy is the ability to do work. Energy flows in one direction in an ecosystem and is not recycled. This is because during the transfer of energy from one level to another, energy is lost. Most of the energy received from the sun by producers, plants, is lost as heat to the surroundings. The rest energy is converted by plants to produce food in the form of chemical energy.
Primary consumers feed on plants and secondary consumers feed on the primary consumers and so on up to quaternary consumers. However, at each level of energy transfer, some energy is lost as heat during respiration, some as unused or undigested materials, while some others are used for each organisms metabolic activities. About 90% of energy in a trophic is used at that trophic level. Therefore, only about 10% as much energy is available to organisms at each successive trophic level. Therefore, energy is not recycled in ecosystems.
Earth's atmosphere maintains its temperature by means of the earth's energy balance. This refers to how incoming from the sun and outgoing energy from the earth are in balance, thereby keeping earth's temperature constant.
Decomposers, are organisms such as bacteria, fungi, and small animals such as ants and worms that eat and decompose dead and waste organic matter and which recycle nutrients back into food chains making them available for plants use. Therefore, decomposers are an essential components of all ecosystems.
A partial DNA sequence for normal hemoglobin and a partial DNA sequence for sickle-cell anemia are shown below.

C. a mutation in the genetic code. D. an incomplete separation of chromosomes.
Answer:
C. a mutation in the genetic code.
Explanation:
A mutation refers to any change or alteration to the nucleotide sequence of a gene caused by mutagen or mistakes during replication. Depending on the manner of occurrence, mutation can be of different types. In this question, partial DNA sequence for normal hemoglobin is given as: G-G-A-C-T-T-C-T-T while the partial DNA sequence for sickle cell anaemia is given as: G-G-A-C-A-T-C-T-T.
From careful observation of the two two DNA sequences above, it can be realized that a SUBSTITUTION MUTATION from T to A has occurred in the sequence of sickle cell. Note that substitution mutation is the replacement of one base by another in a sequence.
Which statement describes how heat flows from the coffee to the part of the spoon in the coffee?
Heat flows from the coffee to the spoon through radiation.
Heat flows from the coffee to the spoon through convection.
Heat flows from the coffee to the spoon through conduction.
Heat flows from the coffee to the spoon through radiation, convection, and conduction.
Answer:
C. Heat flows from the coffee to the spoon through conduction.
The heat movement known to move from one area to elsewhere has been called heat transfer. Thermal conduction allows the coffee's heat to reach the spoon. Thus, option C is correct.
What is thermal conduction?A type of heat transfer called thermal conduction occurs when heat flows from one spot to some other place due to the disparity in temperatures between the bodies.
When a body is subjected to thermal conduction, heat energy is dissipated from the body towards the colder or less heated objects. Because the spoon and coffee are at different temperatures, the heat from the coffee is passed to the spoon through conduction.
Therefore, thermal conduction is the process through which the coffee heats the spoon in the cup.
