Answer:
The dietary differences between China and the US can be explained by the cultural, social and economic background that each of these countries had.
Explanation:
The main difference in food between countries is due to the culture of each country. This culture determines which elements are apt to be consumed and which are not. An example of this is dog food in China, which is very cultural, while the US and most Western countries do not welcome dog food because of its cultural context. Another example can be seen in the feeding of guinea-pig meat in Peru, however, other Latin American countries do not appreciate this type of meat.
The economic and social history of countries can also cause dietary differences. This is because these two factors change society and promote access to more modern and archaic foods.

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.

About 10,000 years ago, around the time of the last ice age, Cheetahs nearly became extinct. Recent efforts have helped them recover, but cheetahs alive today have nearly identical DNA. This is a result of:
Answer:
smaller gene pools for breeders to work with
Explanation:
when the cheetahs almost went extinct there were less viable males/females for the cheetah breeders to work with leading to smaller less diverse gene pools
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.

What terms applies to a period in
evolutionary history when a species shows
little or no change?
Answer:
Punctuated equilibrium
Explanation:
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.
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.

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.
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.
hope this helps you :)

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.

The pharynx is the structure in the body that serves as a pathway of both air and food. How does the body make sure that food does not get into the lungs?
Answer: The body makes sure that food does not get into the lungs because the epiglottis closes the air pathway so that food will not enter it.
Answer:
food getting to the lungs will be aspiration
Explanation:
A flap of tissue called the epiglottis sits over the top of the trachea. This flap blocks food and drink from going down into the trachea when you swallow hence preventing food from getting into the lungs

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.
what use are the descending branches of glacial plants to them?
Answer:
Explanation:
A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. Glaciers slowly deform and flow under stresses induced by their weight, creating crevasses, seracs, and other distinguishing features. They also abrade rock and debris from their substrate to create landforms such as cirques, moraines, or fjords. Glaciers form only on land and are distinct from the much thinner sea ice and lake ice that forms on the surface of bodies of water.
