Three complex carbohydrates that are very important in living things are starch, cellulose, and glycogen (see below).. All three of these polysaccharides are polymers of glucose, yet they behave very differently in our bodies. We can digest starch and glycogen, but not cellulose. Examine the drawing of these three polysaccharides below. What differences can you see between these molecules that might explain why
Answer:
The functional group highlighted in pink alternates its position on the carbohydrate molecule
Explanation:
Complex carbohydrates or polysaccharides are large molecular weight molecules composed of repeating unit of simple carbohydrates which are joined together by covalent bonds known as glycosidic bonds. These glycosidic bonds are foremd between the carbon at position number 1 (known as the anomeric carbon) of one simple carbohydrate and a hydroxyl group of another simple carbohydrate.
The configuration of these linkages determines the properties and functions of the complex carbohydrates. The complex polysaccharides starch, glycogen and cellulose are all composed of glucose monomers linked together by glycosidic bonds.
In storage polysaccharides such as starch and glycogen whose function is to store the simple carbohydrate glucose for when needed by the organism, the glycosidic linkages are said to be in α-linkages, placing the functional groups (CH₂OH) all on the same side.
Even the branching points in glycogen are all in α-linkages. Humans have the enzymes to break these bonds so that starch and glycogen molecules can be metabolized by the body.
In a structural polysaccharide such as cellulose, the glycosidic linkages are β-linkages which results in alternating positions for the functional groups. Since humans do not have the enzymes responsible for the breakage of these linkages, hence, we cannot digest cellulose in our bodies.

The graph here shows the relative change in energy level for the reactants and the products of photosynthesis. Given the energy levels modeled in the graph, which statement accurately compares the energy of the products and the reactants with regards to
photosynthesis?
A)Water and oxygen have the highest energy compared to glucose and
carbon dioxide.
B)
Glucose and oxygen gas have higher energy levels compared to water and
carbon dioxide.
C)
Glucose and water have the same energy levels compared to carbon
dioxide and oxygen gas.
D)
Glucose and oxygen have a lower energy level associated with them
compared to carbon dioxide and water.
Answer: The answer is B I just took the quiz
Explanation:
Glucose and oxygen gas have higher energy levels compared to water and carbon dioxide is accurately compares the products and the reactants with regards of photosynthesis.
What is Photosynthesis?Green plants and certain other organisms convert light energy into chemical energy through a process called photosynthesis. Light energy is gathered and utilised during photosynthesis in green plants to change water, carbon dioxide, and minerals into oxygen- and energy-rich organic molecules.
It is impossible to overstate the role that photosynthesis plays in sustaining life on Earth. There would soon be little food or other organic materials on Earth if photosynthesis stopped. The majority of life would vanish, and eventually, the atmosphere of Earth would contain almost no gaseous oxygen.
Only chemosynthetic bacteria, which can use the chemical energy of specific inorganic substances and are not reliant on the conversion of light energy, would be able to survive in such an environment.
Therefore, Glucose and oxygen gas have higher energy levels compared to water and carbon dioxide is accurately compares the products and the reactants with regards of photosynthesis.

Understanding Dose vs Exposure
John works applying pesticide X to agricultural fields. He spent the morning cleaning out a tank that had contained concentrated pesticide X. The tank was large and he was standing in water all morning (4 hours) power washing the tank. Human skin is a wonderful barrier to entry of compounds as long as it is dry and intact, but wet wrinkly skin can absorb toxins. About 5% of pesticide X absorbs into wet skin and John was in contact with water that had a total of 32 g of the pesticide in it.
After the morning is over, John has lunch but does not wash his hands; he has 2 g of the pesticide on his hands. Pesticide X has about 90% absorption from an oral dose.
Finally, John works in the field in the afternoon a crop plane flies over dusting the crops with pesticide X, the air he breathes in has a total of 5 grams of the compound in it. Pesticide X is known to have absorption of about 50% through inhalation.
What is John’s exposure to Pesticide X and what is his dose?
Route of Exposure Exposure (grams) Dose (grams)
Dermal
Oral
Inhalation
Total
Looking at the total exposure and dose, what percentage of his exposure was a dose?
Answer:
The correct answer is - 15.13%
Explanation:
According to the question, the exposure of the pesticide X to the skin of John is by different routes and amount of the exposure is given and the percentage value is calculated as well:
Route of exposure --- exposure in gram---Dose in gram
Dermal ------------------------32-----------------------32*5/100= 1.6
Oral------------------------------2-----------------------2*90/100= 1.8
Inhalation----------------------5-----------------------5*50/100= 2.5
Total --- -----------------------39 -----------------------5.9
On the basis of this, the exposure is mainly by inhalation, the total exposure is about 39 grams about 5.9 percent. However,
The percentage of dose exposure = (5.9/39)*100
= 15.13%

Type II survivorship curves Your answer: are characteristic of humans and elephants. typify a population in which all ages have an equal chance of survival. indicate a high mortality rate in the very young. show that very few young are produced, that each is given parental support, and that most individuals live a long life and die of old age. are typical of annual plants
Answer:
b. typify a population in which all ages have an equal chance of surviving. → YES
e. are typical of annual plants → YES
Explanation:
Different species have survival curves differently shaped. In general terms, there are three different survival curves.
Type I. Mortality often occurs at the end of the cycle, representing species with low mortality. Organisms exhibiting this type of survivorship curve have long cycles of life and high probabilities to survive until they are old enough. These species have few descendants and spend too much time and energy in parental care to ensure their reproductive success. Type II. The probabilities of dying are equals all along the cycle, at any age interval. The number of dead individuals remains constant from the beginning to the end of the life cycle. These species have reduced offsprings, and they ensure their reproductive success by providing some significant parental care. Type III. Significant mortality during the early stages of life. Only a few individuals reach the later life stages, getting to survive their first period of life. Survivors usually have a long life. These species produce big offsprings at the same time, but they provide little or no parental care. Their reproductive success relies on the number of descendants.Type II survivorship curves:
a. are characteristic of humans and elephants → No, this is Type I curve
b. typify a population in which all ages have an equal chance of surviving. → YES
c. indicate a high mortality rate in the very young. → No, this is Type III curve
d. show that very few young are produced, that each is given parental support, and that most individuals live a relatively long life and die of old age. → No, this is Type I curve
e. are typical of annual plants → YES
What pressure, in atm, will be exerted by 8 moles of a gas at 300
Kelvin if it is contained in a 50 Liter vessel?
Answer:
3.94 atm
Explanation:
Using the general gas law equation as follows;
PV = nRT
Where;
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
T = temperature (K)
According to the information provided in this question;
P = ?
V = 50 L
T = 300K
n = 8 mol
Using PV = nRT
P = nRT/V
P = (8 × 0.0821 × 300) ÷ 50
P = 197.04 ÷ 50
P = 3.94 atm

Effects of temperature on the permeability of Rhoea discolour leaf full lab report. Pdf
Answer:
The results of the former experiments of the author which showed that the permeability of protoplasm increases in light and decreases in the dark were confirmed by the investigations of several authors and by the results obtained in the present paper. 2. The results of investigators who endeavor to show that the permeability increases in light only for some substances, while it may decrease in light for other substances, and that the permeability of protoplasm of some plants increases in the dark while it is not changed by the change of illumination in other cases, are incorrect since the methods used by these investigators to determine the permeability were inexact or faulty

The precipitation that fell at this
location was most likely in what form ?
Answer:
in snow form because the weather was mostly below water's freezing point, so it would snow instead of rain.
Explanation:
Maximum precipitation increases in the Antarctic region during the month of July because Antarctica has snowfall at that time of year due to its location at the earth's southern pole, so it has high precipitation in that area.
What is the significance of the Antarctic region?It is the earth's southernmost continent, where the population is negligible, but there are many significant things available that are used for scientific research, such as oceanography and glaciology, as it has a wide variety of ecosystems, including penguins, seals, whales, and many other sea animals that are generally not found in the sea or in the river.
Hence, maximum precipitation increases in the Antarctic region during the month of July because Antarctica has snowfall at that time of year due to its location at the earth's southern pole, so it has high precipitation in that area.

ASAP Name one challenge we need to overcome by using solar panels
Answer:
It actually Polutes the enviornment more to own solar panels. This Is caused by the production and the dismemberment of the way its made.
Explanation:
Solar panels are composed of photovoltaic (PV) cells that convert sunlight to electricity. When these panels enter landfills, valuable resources go to waste. And because solar panels contain toxic materials like lead that can leach out as they break down, landfilling also creates new environmental hazards. The potential environmental impacts associated with solar power—land use and habitat loss, water use, and the use of hazardous materials in manufacturing—can vary greatly depending on the technology, which includes two broad categories: photovoltaic (PV) solar cells or concentrating solar thermal plants (CSP).
