Trace what happens to a piece of bread as it enters the mouth to the large intestine. Be sure to mention each organ of the digestive system and what happens to the bread in each part. ( can you put it in high school level)
Answer:
Bread is a carbohydrate.
Digestion of carbohydrates begin from the mouth.
As the bread is eaten and it is been chewed, the salivary amylase act on it.
This is also called mastication which is the breaking down of large pieces of bread into smaller pieces.
The salivary amylase break the monomeric bond between the dissacharides and starches by breaking amylose and amylopectin into smaller glucose.
When it's get to the stomach there is no further breaking down in the stomach because amylase do not get to the stomach because of stomach acidity. The strong peristaltic contraction of the stomach make it to form uniform chyme.
When the chyme entered the small intestine, the pancrease releases the pancreatic juice which contain amylase that breakdown dextrins into shorter carbohydrates. Additional enzymes are released which break maltose into two glucose and this enzyme is called maltase.
Sucrase breakdown sucrose into glucose and galactose.
There are cells in the small intestines which contain membranes that have protein transport which get monosaccharides and other nutrients to be absorbed in the blood.
The liver receive glucose, fructose and galactose and store them which is later use by the cells.
Explanation:
Digestion is the breakdown of large complex food into smaller pieces which can be easily absorbed by the body.
The goal of carbohydrates digestion is to breakdown complex carbohydrates and dissacharides into monosaccharide that can be absorbed into the body.

Which is one place that glaciers are found?
A) in the ocean
B) in the tropics
C) at low altitudes
D) at high latitudes
Answer:
I believe it is at high latitudes
Explanation:
I say this because many glaciers are found in Greenland and Antarctica which are both located in higher latitudes
Glaciers are found at HIGH latitudes (Option D).
Latitude refers to the geographic coordinates which are used to indicate specific north-south positions on the Earth's planet.
Low latitudes are geographic coordinates found between the 0 degrees (Equator) and 30 degrees north-south, whereas high latitudes are found between 30 degrees and 90 degrees north-south positions.
At low latitudes, the energy from the sun is able to melt the polar ice.
Thus, glaciers are found at high latitudes because the highest latitudes get a minor amount of energy from the sun compared to low latitudes.
In conclusion, glaciers are found at HIGH latitudes (Option D).

What other adaptation could have helped koalas as they evolved from land-dwellers to tree-dwellers?
Answer:
I believe it is
fur color that closely matches the eucalyptus bark color
or B
Explanation:
My reasoning is that, if they evolved from land-dwellers to tree-dwellers, they will have almost no need for longer legs for running, as they only need strong legs and arms for climbing, not running.
The ability to communicate better doesn't really mean anything, as they are now all closer or further away, since they are all in trees now. This doesn't mean that they necessarily need to communicate better.
The ability to have several offspring at one time could be the answer, but isn't really necessary.
Predators would hunt for the koalas in the trees now, so to hide, they would need to go inside the tree trunk or camouflage themselves, which most creatures do by blending into their surroundings or changing skin color over time.

Un jardinero cruzó dos plantas de flores rosadas, con la esperanza de obtener plantas con flores del mismo color. Su sorpresa fue encontrar que, en la descendencia, aparecían flores rojas, rosadas y blancas en la proporción 1:2:1. Pregunta: a) ¿En qué se diferencia la herencia del color de estas flores y la de los guisantes? b) Indica el genotipo de las plantas del cruzamiento descrito.
Answer:
Este es un ejemplo de dominancia incompleta. Es una ocurrencia genética que ocurre cuando un gen dominante no expresa su manifestación completa en el alelo recesivo en un alelo dominante heterocigoto.
Por lo tanto, ambos rasgos se manifiestan, lo que resulta en la combinación de los dos alelos para los colores (blanco y rojo). Se dice que el alelo rojo dominante exhibe un dominio parcial sobre el alelo blanco recesivo, y esto da como resultado el alelo completamente rosado.
De acuerdo con la ley mendeliana, las dos flores rojas son heterocigóticas. Por lo tanto, las flores rojas heterocigóticas dominantes deben ser R. El alelo blanco es recesivo (rr) enmascarado por el rojo R,
Sin embargo, cuando se cruzan los dos alelos heterocigotos rojos:
Los fenotipos están en forma de
RR, (1) rojo Rr Rr (2) rosa rr (1) Blanco.
Esto ocurre porque el alelo rojo dominante no era total / completamente dominante en el alelo recesivo blanco en cada uno, lo que da como resultado un alelo rosa (el tercer fenotipo)
This is an example of incomplete dominance.It is a genetic occurrence which occurs when a dominant gene does not express it full manifestation on the recessive allele in an heterozygote dominant allele.
Therefore,both traits are manifested which results in the blend of the two allele for colors(white and red).The dominant red allele is said to exhibit partial dominance over the recessive white allele.And this results in the entirely pink allele.
Based on Mendelian law the two red flowers are heterozygotes .Therefore, Red heterozygote dominant flowers should beRr.The white allele is recessive(rr) masked by the R-red,
However,when the two red heterozygote alleles are crossed:
The phenotypes are in the form of
RR,(1) red Rr Rr(2) pink rr(1)White.
This occurs because, the dominant red allele was not fully/completely dominant on the white recessive allele in each,which results in pink allele(The third phenotype)
Explanation:
The branch of science which deals with living beings is called biology.
The language of the question is different so it is difficult to answer it.
According to the data given in the question, they are discussing incomplete dominance because the ratio is 1:2:1.
The cross in which the dominant parent is not able to show its character and does not able to suppress the recessive gene. In this case, the plants show the character of somewhere in between both of the cases.
Therefore, they get the ratio of 1:2:1 which indicates the phenotype of red: pink: white.
Hence, the correct answer is incomplete dominance.

What might be the correlation between the clarity of the lake water and the occurrence of the full body plate trait? What might you conclude about the clarity of the water from 1950 to 1980 based on this correlation?
Answer:
The clarity of the lake water isn’t specified so assuming the clarity improved and other predatorial fish were able to target stickleback fish more easily the full body plating had to come into play to make it more difficult for them to be preyed upon and to give them a better chance at escape.
Explanation:
The clarity of the lake water though not specified in this context. The full
body plate will help the stickleback fish to escape from its predators.
Water clarity is defined as the amount of light which is able to penetrate into
water bodies thereby making it easier for animals in it to see and hunt
properly for their food.
The improvement in water clarity will give the predatorial fish an advantage
to easily hunt stickleback fish. The full body plate trait will therefore give it a

Draw a cartoon strip or write an article to summarise the greenhouse effect and how it can lead to global warming. Include the following: 1. Role of the atmosphere (greenhouse gases) in maintaining the temperature on Earth, 2. Carbon cycle between plants, animals and the atmosphere, 3. Humans burn fossil fuels, run cars and generate electricity upsetting the balance, 4. Increased amount of carbon dioxide in the atmosphere leads to increased global temperature, 5. Effects of global warming.
The greenhouse effect is an essential phenomenon for life on earth. However, human activities such as pollution and burning of fossil fuels have caused an intensification of this effect, which has harmed the atmosphere and is directly related to global warming.
The greenhouse effect is formed by a layer of atmospheric gases that settle around the planet and allows a temperature suitable for life to reach the earth's surface. Therefore, we can guarantee that this effect is essential for our survival. It is necessary that the amount of these gases is kept in equilibrium for this temperature to be constant.
However, the burning of fossil fuels, industrial activities, pollution (caused by vehicles, aerosols, fires, among others), the use of non-renewable energy releases greenhouse gases into the atmosphere daily and in large quantities.
This causes the layer of greenhouse gases that circulates the earth to become more and more expanded, not being able to disperse solar radiation easily and causing an increasing temperature. All that heat is retained in the atmosphere, thus generating global warming, which allows the planet's temperature and ocean water to increase dramatically, which can cause various harmful effects to life on the planet.
For this reason, it is necessary to carry out public policies that reduce pollution and encourage the use of clean and renewable energy that does not increase the layer of greenhouse cases, promoting well-being and life on earth.

Dr. DeRidder lesions, or damages, the ventromedial hypothalamus in one group of rats and the lateral hypothalamus in another group. What effect might he expect on the eating behavior of each group of rats? Both groups should begin overeating and become grossly obese. Rats with ventromedial lesions should begin overeating; rats with lateral lesions should stop eating. Both groups should stop eating and perhaps eventually starve to death. Rats with ventromedial lesions should stop eating; rats with lateral lesions should begin overeating.
Answer:
Rats with ventromedial lesions should begin overeating; rats with lateral lesions should stop eating
Explanation:
The feeling of hunger stimulates a desire to eat.
The lateral hypothalamus is responsible for making an organism hunger and craves for food upon receiving any stimulation or signal that causes hunger.
A damaged to the lateral hypothalamus would mean the organism would not be able to sense hunger and thus, there would be no desire to eat. Hence, the rats with lateral lesions should stop eating.
On the other hand, the ventromedial hypothalamus is responsible for quenching hunger and signaling to the organism that it is full, hence, it would stop eating. However, when the ventromedial hypothalamus is damaged, the organism would not be able to tell when to stop eating. Hence, rats with ventromedial lesions should begin overeating.

Plant B listens to rock music for three hours each day. Plant C listens to country music for three hours each day. Plant D does not listen to any music at all.
Answer:
C
Explanation:
The complete question: A student conducts an experiment to see how music affects plant growth. The student obtains four identical plants. Each one is potted in the same type of soil and receives the same amount of sunlight and water each day. Plant A listens to classical music for three hours each day. Plant B listens to rock music for three hours each day. Plant C listens to country music for three hours each day. Plant D does not listen to any music at all. In the experiment described in the scenario, which group represents the control group? A. Plant B B. Plant A C. Plant D D. Plant C?
The control group here would be plant D.
Control groups are usually used to minimize the effects of extraneous variables in the course of experiments and to ensure that the differences observed in different experimental groups are due to the effects of the independent variables.
In this case, all the plants were exposed to music except the control group because the aim of the experiment is to measure the effects of music on plant growth. Any difference in growth observed between those exposed to music and the control group can reliably be considered to be due to the music.
The correct option is C.
