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.

Define photosynthesis, cellular respiration,
autotroph, heterotroph, herbivore, carnivore,
omnivore
Answer: Omnivore is an animal that eats both plants and animals.
Carnivore is an animal that eats only meat. Herbivore is an animal that eats only plants.
Heterotroph is an organism deriving its nutritional requirements from complex organic substances.
Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
Autotroph is an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.
Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate (ATP), and then release waste products.

what is the difference between cell structure and cell function?
Answer:
These cells have a membrane-bound nucleus that houses their DNA and contain extensive internal organelles (“little organs”) that perform specific functions. ... Differences occur in size, shape, and presence and number of various organelles and other structures. Each cell's structure correlates with its specific function.
Explanation:
Answer:
A cell can be defined as the smallest unit of life and an example include muscle cells. An aggregation of cells form tissues.
The major difference between a cell structure and cell function is in their functions and physical properties.
Cell structure: This talks about how the cells look like when viewed. A call contains components such as the nucleus, cytoplasm, cell membrane etc and each has their various functions to ensure the organisms/animals are able to perform various life activities.Cell function: This on the other hand refers to the various functions which a cell is able to perform and this is dependent on the component in question such as the nucleus which controls cell activities and cytoplasm which provides support and helps to house other organelles.

A partial DNA sequence for normal hemoglobin and a partial DNA sequence for sickle-cell anemia are shown below. G-G-A-C-T-T-C-T-T Normal hemoglobin G-G-A-C-A-T-C-T-T Sickle-cell anemia Based on the DNA sequences, sickle-cell anemia is caused by A. a sex-linked trait. B. a dominant nucleotide. 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.

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.

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

Movement of individuals into or out of the population, called gene flow, impacts evolution of populations because:_________.
a. it can lead to extinction of one or more populations.
b. it may cause genetic drift.
c. it leads to a redistribution of alleles
d. adaptive radiation results.
e. a founder effect will occur.
Answer:
c. it leads to a redistribution of alleles
Explanation:
The gene flow can be defined as the movement of genetic material from one population to another within the same species. This movement may be associated 1-with the migration of individuals and subsequent reproduction of these organisms in the new population or 2-with the movement of gametes (eg., pollen dispersal) among populations. In both cases, gene flow is known to alter the frequency of particular alleles between populations and consequently also modify the evolutionary patterns of these populations.
Gene flow is the migration of genes or alleles and refers to the transfer of the genetic material. If the rate of the gene flow is high then two populations will say to be an effective population.
It just leads to redistribution of the genes or alleles with the in the popualtion of species. Hence the option C is correct.Learn more about the individuals into or out of the population, called gene flow.
