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
Answers
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.

Answer:
A. Destruction of terrestrial biota
Explanation:
all the other answers would decrease the carbon output. thickening of ocean sediments reinforces a carbon reservoir (which stores carbon), reduction in the use of fossil fuels would reduce the amount of carbon emissions, increase in marine biota = increase in carbon storage because marine biota is also a carbon reservoir.
Destruction of terrestrial biota would cause excess output because terrestrial biota is a carbon reservoir, and all of that carbon would be released into the carbon cycle.

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?
Answers
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
According to the diagram below, what type of organism converts atmospheric nitrogen (N2) to ammonia (NH3) and then to nitrites (NO2-) and nitrates (NO3-)?
Answers
Answer: Nitrogen-fixing Bacteria
Explanation:
In the Nitrogen cycle, nitrogen fixing bacteria are very important in ensuring that plants get nitrogen to enable them grow and as animals have to eat plants, these bacteria are essential for our survival as well.
Plants are unable to use atmospheric nitrogen but nitrogen-fixing bacteria are able to synthesize ammonia from atmospheric nitrogen. They can then convert this to Nitrites and Nitrates which are more useful to plants and animals by extension.

Rocky's class recently got pet turtles. When putting together the habitat, decomposers were added to the soil, as well as some smaller organisms that turtles eat. Some students wanted to get "fake" plants for the terrarium, but Rocky insisted that this would negatively affect the carbon and oxygen cycles.
Which of the following reasons support why Rocky is correct?
Group of answer choices
A) Carbon won't be removed from the air.
B) Photosynthesis won't occur.
C) The turtles won't be able to breathe.
D) All of these are correct.
Will mark as brainliest if correct
Answers
Answer:
The correct answer is - D. All of these are correct.
Explanation:
It is clear that the terrarium is sealed or not, if it is open to the outside environment or not. Considering it sealed and no outer interaction, then if a fake plant to this terrarium then there will be no photosynthesis will take place as there are no green plants to capture the sunlight and make glucose and no way to release oxygen for the other organisms.
If in this no green plants then the removal of CO2 will not be possible. Higher amount of carbon and without oxygen turtles would not be able to survive even though there is food for them.

Answers
Answer:
less packaging of oxygen
Explanation:
normal RBC (red blood cells) have a large surface area for oxygen packaging due to its biconcave shape but when mutation occurs the RBC being produced by the short bones is sickle shaped reducing surface area of haemoglobin exposed, responsible for packaging oxygen so tissues don't get right amount of oxygen
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?
Answers
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%

What do coral reefs and estuaries have in common?
Answers
Answer: hewo, there! your answer is below
stuaries are areas of water and shoreline where rivers meet the ocean or another large body of water, such as one of the Great Lakes. Organisms that live in estuaries must be adapted to these dynamic environments, where there are variations in water chemistry including salinity, as well as physical changes like the rise and fall of tides. Despite these challenges, estuaries are also very productive ecosystems. They receive nutrients from both bodies of water and can support a variety of life. Because of their access to food, water, and shipping routes, people often live near estuaries and can impact the health of the ecosystem.
Explanation: Here's some Info Below <3
shallow water, reef-building corals have a symbiotic relationship with photosynthetic algae called zooxanthellae, which live in their tissues. The coral provides a protected environment and the compounds zooxanthellae need for photosynthesis. In return, the algae produce carbohydrates that the coral uses for food, as well as oxygen. The algae also help the coral remove waste. Since both partners benefit from association, this type of symbiosis is called mutualism.
Deep-sea corals live in much deeper or colder oceanic waters and lack zooxanthellae. Unlike their shallow water relatives, which rely heavily on photosynthesis to produce food, deep sea corals take in plankton and organic matter for much of their energy needs.

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
Answers
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
ASAP Name one challenge we need to overcome by using solar panels
Answers
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).
