What is an endoscope?An endoscope is a medical instrument that consists of a long, thin, flexible tube equipped with a light source and a camera at the tip. It is used by doctors to visualize and examine internal organs or structures within the body. The endoscope can be inserted through natural body openings like the mouth, anus, or small incisions to access various areas of the body.
It allows for direct visualization of the internal organs, capturing real-time images or videos that can be viewed on a monitor. Endoscopes are commonly used for diagnostic purposes, such as examining the gastrointestinal tract, respiratory system, urinary tract, or joints. They can also be used for therapeutic procedures, such as removing polyps, taking biopsies, or performing minimally invasive surgeries.
Endoscopes have revolutionized medical diagnostics and interventions by providing a less invasive alternative to traditional surgical methods.

1. Complete the unfinished DNA strand from below.
2. What m-RNA strand would be formed from the DNA strand that you just made in #1 above?
3. Using the codon chart in the lesson, what amino acids would be aligned from the following m-RNA strand?
A U G G C G G A A
4. If the first base in the sequence above (#3) were mutated to a C, what would that do to the amino acid sequence?
5. If you were given a single tiny chunk of a nucleic acid strand and asked if it was DNA or RNA, what things would you look for to tell?
Explanation:
1. is T G C A T because it is a DNA as it contains thymine.
2. so mRNA strand would be U G A C G U A as it is in RNA so it would be uracil with adenine.
3. is Met- Ala- Glu
4. if is mutated to a C then it would be C U G G C G A A
so it would be Leu-Ala-Glu.
5. you can look for if it contains thymine or uracil. If thymine then DNA if Uracil then RNA. you can also see if it is double or single strand. if double than DNA if single than RNA.

evolutionary history when a species shows
little or no change?
Answer:
Punctuated equilibrium

The idea of "punctuated equilibrium" suggests that species will show little to no evolutionary change throughout their history. When evolution does occur, according to this idea, it happens sporadically and relatively quickly compared to the species' full duration on Earth.
When amino acids are degraded for energy or glucose production, their amine groups are incorporated by the liver into ____.
Answer:
The correct answer is - urea.
Explanation:
In our body, to produce energy or produce glucose our body breaks the amino acids, it gets from proteins mainly. These amino acids are mainly breakdown into amine groups.
The human body has a unique ability to pack ammonia(amine group) by converting it to urea and incorporated and produced by the liver using 2 molecules of ammonia (NH3) and 1 molecule of carbon dioxide (CO2). This incorporated urea is then secreted from the liver and incorporated into the urine in the kidney for further process.
a permanent disease process that is characterized by destruction of the alveolar walls and distention of the alveolar sacs is a type of COPD called
Answer:
Emphysema
Explanation:
Pulmonary emphysema disease progressively destroys the fibers that promote respiration, leading to a decrease in respiratory function, emphysema being a more serious complication of any bronchopulmonary obstructive inflammation. In emphysema, the walls that separate many of the alveoli are damaged and gas exchange in the lungs decreases. This disease originates when the pulmonary alveoli are progressively destroyed and difficulty in breathing becomes greater and greater. When destroyed, a larger space is created, instead of small chambers. And this affects the length of the lungs and the amount of oxygen that reaches the blood.

How can a scientist determine if two species are obligate mutualists? The scientist should observe the species in the environment to determine the types of interactions that the two species have. Then, the scientist should transplant each species alone to a new area and simultaneously transplant both species together to see if the single-species transplants die. The scientist should observe the species in the environment, determine the types of interactions that the two species have, and then add an invading species to see if it outperforms one of the other species. The scientist should observe the species in the environment, determine the types of interactions that the two species have, and then transplant both species to a new location to observe if they do better or worse than the individuals in their old location. The scientist should observe the species in the environment, determine the types of interactions that the two species have, and then remove one of the species to see if the other species does not survive.
Answer:
The scientist should observe the species in the environment to determine the types of interactions that the two species have. Then, the scientist should transplant each species alone to a new area and simultaneously transplant both species together to see if the single-species transplants die
Explanation:
When two species are obligate mutualists, both species benefit one another in such a way that one cannot survive without the other. Hence, in order to find out if two species are indeed obligate mutualists, they should be transplanted together away from other species on one side, and also transplanted individually on another side.
If they are obligate mutualists, the individual transplant would find it difficult to survive and should die in no time while the transplant done together should survive. All other factors being kept constant.
Most body water comes from:moisture absorbed through the skin.fluids we drink.the food we eat.metabolism.
Answer:
fluids we drink.
Explanation:
Most body water comes from fluids we drink such as water, juices etc. Our body obtains water by absorbing it directly from the digestive tract. A small amount of water is produced in the metabolism of food particles. Our body loses excess amount of water by excreting it in the form of urine from the body. Kidney is the organ that filters waster materials and excess water from the blood and remove it from the body.
A founding population usually has lower genetic diversity than the original population it came from. For those alleles that are shared by the two populations, how are allele frequencies different (or similar)
Answer:
In the founding population, the allele frequency is different from the original bigger-sized population. The size of the new population affects this difference even more. Some of the alleles will tend to increase, while some others will tend to decrease in frequency.
Explanation:
Genetic drift is an evolutive force. It is the random change that occurs in the allelic frequency of a population through generations. Its effects are harder in a small-sized population, meaning that the magnitude of this change is inversely related to the size of the original population.
Genetic drift results in some alleles loss -including the beneficial ones-, while some other alleles get fixated. Low-frequency alleles are the most likely to be lost. The changes produced by genetic drift accumulate in time and results in a loss of genetic variability within a population.
Genetic drift affects a population and reduces its size dramatically due to a disaster or pressure -bottleneck effect- or because of a population split -founder effect-. The bottleneck effect most likely affects smaller populations.
Founder effect refers to the origin of a new population from only a few individuals that are coming from a bigger-sized population. These founder individuals, which are carrying some of the genes of the original population, settle down in a new area and reproduce. The new and small population might or might not be genetically representative of the original one. Some rare alleles might be exceeded or might be lost by complete. Consequently, when the small population increases in size, it will have a genetically different composition from the original one. In these situations, genetic variability is reduced, and there exists the possibility of developing a peculiar allelic composition. When the number of individuals that originated the new population is low, the founder effect will be very extreme because the genetic drift effects are inversely proportional to the original number of individuals.
How many capillary beds must a red blood cell pass through to move from an artery in the left arm to the left ventricle of the heart
Answer:
two capillary beds
Explanation:
Capillary beds are networks of capillaries that supply blood to the organs and/or areas of the body, in which nutrients and gas exchange (i.e., O2 and CO2) between red blood cells and tissues take place. Smaller arteries (i.e., arterioles) diverge into capillary beds composed of 10 to 100 capillaries, the smallest blood vessels in the body that connect the arterioles and the venules. Red blood cells usually flow into a capillary bed from a metarteriole (i.e., a microvessel that connects arterioles and capillaries). Red blood cells sometimes pass through two capillary beds before reaching the heart. The left heart ventricle is a muscle required for pumping red O2-rich blood out through the aortic valve into the aorta, whereas arteries are large blood vessels that branch into arterioles in order to carry blood to the capillary beds.
The muscle fibers within muscle cells are divided into myofibrils, which are further divided into _____, the contractile units of muscles.

Just after they taste a sweet liquid, mice are injected with a drug that produces an immune response. Later, the taste of the sweet liquid by itself triggers an immune response. This best illustrates
Answer:
This question lacks options, options are:
a) classical conditioning
b) observational learning
c) spontaneous recovery
d) operant conditioning.
The correct answer is a.
Explanation:
The classical conditioning theory derives from the experiments of the Russian physiologist Ivan Pavlov, he hypothesized that when any stimulus predicts the occurrence of another stimulus that triggers an automatic response, that first stimulus would acquire the ability to trigger that response, in other words , is a type of learning according to which an originally neutral stimulus, which does not provoke a response, becomes able to provoke it thanks to the associative connection of this stimulus with the stimulus that normally provokes said response. The conditioning of the immune response is built on the same principles of the classical conditioning paradigm described by Ivan P. Pavlov in which an environmental stimulus that by itself does not produce any immune reaction (conditioned stimulus), is associated with substances that stimulate or they suppress immune function (unconditioned stimulus), and finally, by presenting the conditioned stimulus alone, trigger the appropriate immune response.
