starch, glycogen, and cellulose are all made of chains of AMINO ACIDS?
Glucose is the basic unit of the polymers, starch, glycogen and cellulose. They are made of glucose chains.
What is glucose?Glucose is a carbohydrate monomer and is the basic unit biological polymers such as cellulose and starch. Linkage of a large number of monomers make a polymer such as cellulose , starch etc.
The bond type in each polymer may vary. The linkage of glucose units depends on the conformation of glucose molecules. Glucose can exist in both alpha and beta structure. Both these structure prefer cyclic conformation.
Starch and cellulose is made of alpha-1,4 glycosidic linkage between glucose molecules and glycogen is made of beta-1,4 glycosidic linkage. cellulose polymer contains more glucose units than the other two.
Therefore, starch, glycogen and cellulose are made of glucose chains.

c. Which of the substances in Model 2 would dissolve well in water? Justify your reasoning.
Answer:
The substances which can dissolve in water are termed polar substances, whereas the molecules or substances, which are unable to attract water molecules are known as non-polar molecules. Some of the examples of polar molecules are lactic acid, valine, ethanol, sulfur dioxide, and hydrogen sulfide.
Explanation:
Polar substances also referred to as hydrophilic substances, are dissolved in water through hydrogen bonding. The substances can be acidic, neutral, or basic in nature.
For instance, lactic acid is miscible in water, such that it forms a colorless solution. Glucose, lactose, and valine are neutral are readily soluble in water, and basic substances like adenine are dissolved in hot water.
The non-polar substances are known as hydrophobic substances, such that they do not dissolve in water.
For example, fatty acids cannot dissolve in water, as they are long chains of carbon and have less density than water. Also, neutral substances like vitamins (A, D, E, and K) and cholesterol are unable to dissolve in water.
Polar substances dissolve well in water as compared to non-polar substances.
Polar substances would dissolve well in water because water is also a polar substance which makes bond with the the polar substances. The partial positive atom of water attracts the partial negative atom of other polar substances making hydrogen bonding between them due to their opposite charges.
These charges enables them to dissolve in each other whereas non-polar substances can't dissolve in water due to absence of poles so we can conclude that polar substances dissolve in water.

2. Weight loss in subjects eating low carbohydrate diets.
a. Independent Variable:
b. Dependent Variable:
3. The number of hours spent studying biology each week and grades earned on biology exams.
a. Independent Variable:
b. Dependent Variable:
Suggest a control group for each of the following experiments.
4. Cancer rates in students who smoke cigarettes are closely monitored over a 5-year period.
Control Group:
5. Weightlifters are given 400 mg of creatine phosphate every day for 90 days. At the end of the 90-day period each participant is evaluated for improvements in strength.
Control Group:
The independent variable produces an effect on the dependent variable, while the control variable produce no change on the results. In the exposed situations, the independent variables are supplemental O₂, low carbohydrate diets, hours spent studying biology. The dependent variables are Endurance of climbers, Weight loss, grades earned on exams. And the control variable might be time.
--------------------------------------
During an experiment, you need to consider all the variables involved.
Independent (manipulated) variable: Refers to all the variables in an experiment that provoke a response in another variable. An independent variable is the one that changes or is controlled and modified to analyze how another variable responds to it. The researcher changes the independent variable to observe its effects on the dependent variable. Usually, the independent variable is represented by the X letter. Dependent variable: Refers to the variable, which response depends on any change in the independent variable. It represents a quantity of something which value depends on how the independent variable is modified. The change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. It is usually identified by the letter Y. Controlled variables are kept constant in the control groups and the experimental groups. Unlike the independent variable, the controlled variables do not influence the results. These variables do not affect the response of the dependent variable.
1. Endurance in high altitude mountain climbers with and without the use of supplemental O2.
a. Independent Variable: supplemental O2
b. Dependent Variable: Endurance in mountain climbers
The endurance of climbers will depend on the use of supplemental O₂. If they use supplemental oxygen, they will have more resistance than if they do not use it. Supplemental Oxygen is influencing the climbers´ endurance.
2. Weight loss in subjects eating low carbohydrate diets.
a. Independent Variable: low carbohydrate diets
b. Dependent Variable: Weight loss
Having a low carbohydrate diet will lead the subjects to lose weight. Any change in the quantity of the carbohydrate will affect the individuals' weight.
3. The number of hours spent studying biology each week and grades earned on biology exams.
a. Independent Variable: hours spent studying biology
b. Dependent Variable: grades earned on exams
The more hours students spend studying, the higher grades they get on biology exams. The grades depend on the number of hours used to study and are proportional to this variable.
4. Cancer rates in students who smoke cigarettes are closely monitored over a 5-year period.
Control Group: Time → Five years
Time is constant in all the study groups. Independently of the number of cigarettes smoked, or the frequency in which subjects smoke, all the groups will be analyzed for 5 years, and this time-lapse is constant.
5.Weightlifters are given 400 mg of creatine phosphate every day for 90 days. At the end of the 90-day period each participant is evaluated for improvements in strength.
Control Group: Time → 90 days
Time is constant in all the study groups. Independently of the creatine phosphate mg provided to weightlifters, individuals will be analyzed for 90 days, and this time-lapse is constant.

What does light pollution have to do with bird migration?
b.
How would bird migration change after humans disappear?
Answer:
A) Light pollution both attracts and repels migratory birds
In addition to the many hazards that exist in urban areas, cities typically lack the food resources and cover that birds need during migration or when raising their young. ... Darkening skies at night during migration season makes it easier for birds to navigate.
Explanation:
Migration carries high costs in predation and mortality, including from hunting by humans, and is driven primarily by availability of food. It occurs mainly in the northern hemisphere, where birds are funneled on to specific routes by natural barriers such as the Mediterranean Sea or the Caribbean Sea.

Please Hurry). The Science of Biology: Question 1: Explain how sunlight is the primary source of energy for your own life? Question 2: In terms of energy, what is the difference between glucose and ATP? Question 3: Explain the role of a hypothesis in a scientific investigation? ( Will Mark Brainliest if correct).
Answer:
1) The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter. This process begins the flow of energy through almost all food webs 2)Cellular respiration breaks down glucose into water and carbon dioxide producing 38 net ATP molecules. ATP is the energy containing nucleotide in cells while the energy found in glucose is used to make ATP. The key difference between glucose and ATP is the composition of these two molecules 3)The basic idea of a hypothesis is that there is no pre-determined outcome. ... A key function in this step in the scientific method is deriving predictions from the hypotheses about the results of future experiments, and then performing those experiments to see whether they support the predictions
Answer:
Explanation:
1) Well sunlight is very important to each of us because not only it gives us warmth, it also gives us vitamin D, which is very essential for our body.
2) Glucose is the energy that every living being absorbs and stores in their body. ATP is the energy that is ready to be used from every living being.
3) The hypothesis is a very important role in a scientific investigation, because it helps us suppose the experiment that we are about to realize and it's a possible answer to our scientific question.

The temperature at which the egg will able able to hatch is 36°C. This zone is actually called Zone of Hatching Potential. It has a range of 35 - 40.5°C.
What is the Zone of Hatching Potential?Eggs may hatch at temperatures ranging from 35 to 40.5°C (84.5 - 104.9°F).
The optimal temperature (for hens) is 37.5 degrees Celsius (99.5 degrees Fahrenheit); beyond this temperature, in addition to a lower hatch, there will be an increase in the number of crippled and malformed chicks.
No embryos will survive if the temperature rises beyond 40.5°C (104.9°F).
Continuous temperatures in this range, but below the ideal, will impede growth and increase mortality.
Early embryos, once again, are more vulnerable to sustained somewhat low temperatures than later embryos. Lowering the incubation temperature by up to 2°C (3.6°F) after 16 days may be advantageous.
The consequences of short-term temperature reductions varied and will be examined further below.

While waiting at an airport, Neil Campbell once overheard this claim: "It's paranoid and ignorant to worry about industry or agriculture contaminating the environment with their chemical wastes. After all, this stuff is just made of the same atoms that were already present in our environment."
Drawing on your knowledge of electron distribution, bonding and emergent properties, write a short essay (50-100 words) countering this argument.
Answer:
The atoms of each element have a characteristic number of electrons arranged in electron shells. The number of valence electrons determines what types of bonds or ions the atoms may form, so the chemical reactivity of an atom arises from its electron distribution. The properties of compounds emerge from the arrangement of their constituent atoms and of the bonds between them.
Thus, a wide variety of molecules with very different chemical properties can be made from the same basic atoms. Each molecule has a distinctive size, shape, and charge distribution, which determine its highly specific ability to interact with other molecules.
Compounds in chemical wastes may contaminate the environment if their atoms are combined in new arrangements that harm living organisms.
Explanation:
In the past few decays, the chemical and medical industries have undoubtedly proven to be beneficial for the human race and have made significant advancements as it attribute to the synthesis of new drugs and chemicals.
However, in light of these developments, the natural resources and environment have been ignored. We all know that all substances are composed of an atom but their complexity, relation with another molecule, location, and concentration is what impact the environment. For example, the small amount of HCl in the stomach is good but in high concentration, it can cause skin problems.
The environment also reacts the same way as the human body does. Industrial waste is made up of atoms that are already present in the environment, they can have a serious impact on the environment.
For instance, a high concentration of waste in soil alters its physical and chemical properties making it unsuitable for the growth of plants, more algae decomposition in water is toxic to aquatic life.
These are just certain examples but the effect can be more deleterious and thus the statement can be counted with the concern of environmental preservation.

Inhumane factory farming methods have a huge tendency to contribute to environmental degradation. Explain the connection between inhumane factory farming methods and environmental degradation and further motivate why a study on such factors is important.
Inhumane or uncontrolled factory farming methods posses a high risk to the surrounding environment. This is because of the farming activities that can lead to degradation (pollution) of the environment.
Factory farming is an industrialized type of farming that involves both the growing of crops as well as the rearing of livestock in a confined area in order to maximize production at minimal cost.
There are some practices carried out while using this farming method which when poorly managed can lead to the degradation of the environment. They include:
Bush burning: Repeated cycles of bush burning in a given area can damage the soil, making it become powdery and dry with poor nutrient content. Tillage: An over tilled soil will become dry and powdery. Its topsoil can easily be blown away resulting to land erosion.Fertilizers: This must be added to the soil in correct amount, according to the mineral requirement pf the soil that is to be planted on it. This is done to avoid excess fertilizers washing into nearby water bodies.pesticides: These are used to control agricultural pests. Farmers are advised to use them with great care and only when essential.
