The small intestine exchanges nutrients to help maintain homeostasis. Through the process of digestion, food is broken down into smaller pieces. Sugar is a molecule that supplies our cells with energy. Sugar is a large molecule and is transported through carrier proteins. Sugar molecules are often transported into the bloodstream even when the concentration of glucose is higher in the bloodstream than in the intestine. Based on this scenario, is the transport of glucose accomplished through osmosis, diffusion, or active transport?
Answer:
Diffusion
Explanation:
The sugar is spreading to various places within the body and is trying to make one place less concentrated.
Based on the given scenario,the transport of glucose is accomplished through diffusion.
What is diffusion?
Diffusion is defined as the process of movement of molecules which takes place under concentration gradient. It helps in movement of substances in and out from the cell.The molecules move from lower concentration region to a higher concentration region till the concentration becomes equal.
There are 2 main types of diffusion:
1) simple diffusion-process in which substances move through a semi-permeable membrane without the aid of transport proteins.
2) facilitated diffusion- It is a passive movement of molecules across cell membrane from higher concentration region to lower concentration.
There are 2 types of facilitated diffusion one is osmosis and dialysis.

16. Carbohydrates
17. Lipids
18. Carbohydrates
19. Carbohydrates
20. Lipids
21. Lipids
22. Carbohydrates
23. Lipids
Explanation:
Carbohydrates are organic molecules composed of carbon, hydrogen and oxygen. Carbohydrates can be classified into three types: monosaccharides (e.g. glucose), disaccharides (e.g., lactose), and polysaccharides (e.g., starch). Cellulose is a carbohydrate where many glucose rings chain together, while chitin is a polysaccharide consisting of chains of modified glucose molecules.
Lipids represent a diverse group of organic molecules that include, among others, fats, waxes, oils, hormones, etc. Lipids play a role by insulating (and protecting) the body. For example, there is a layer of fats beneath the skin which enables to maintain body temperature relatively constant. In animals, lipids constitute about 50% of the mass of cell membranes. These membrane lipids are mainly phospholipids, glycolipids and cholesterol. There are hormones that derive from lipids such as steroid hormones, which derive from cholesterol. Some examples of steroid hormones are testosterone, estrogen and cortisol.

What challenges do Arctic areas face as a result of global warming? 2) What measures could help deal with the problem? 3) What do you predict will happen to Arctic ecosystems if no measures are taken to reverse the problem of global warming? Explain your reasoning. 4) Which measures do you think are most important to pursue?
Answer:
Global warming is defined as the environmental issue that leads to long term heating of the earth due to human activities such as burning of fossil fuels.
1. Arctic areas are facing huge challenges due to global warming that includes rising sea levels, rapid melting of ice, loss of fish stocks, birds and marine mammals, and changes in climate patterns.
2. Measures that help to deal with the problem are reduction in the use of hydrofluorocarbons, cutting emissions of black carbon, methane, reduce overfishing, and reduction of industrial waste.
3. If there will be no measure taken to reverse the problem of global warming in the Arctic ecosystem, it will cause flood and tsunami in the nearby continents due to the rapid melting of ice, changes in climate patterns, and lead to the extinction of many marine animals.
4. Reduction of industrial waste is the most important measure to pursue because industrial waste contributes most of the greenhouse gases and causes air pollution, land pollution, water pollution, and nuclear pollution. So reduction is industrial waste will reduce the emission of harmful gases in the environment that can reduce the impact of global warming.

Which of the following correctly describes how glucose becomes the product of a chemical reaction?
O Photosynthesis creates glucose using energy, a solid, and a liquid.
O Photosynthesis creates glucose using energy, a gas, and a liquid.
O Cellular respiration creates glucose using a gas and a liquid.
O Cellular respiration creates glucose using a solid, and a liquid
Answer:
[tex]\boxed {\tt B. \ Photosynthesis \ creates \ glucose \ using \ energy, \ a \ gas,and \ a \ liquid}[/tex]
Explanation:
Glucose is made in the process of photosynthesis. It is used in cellular respiration, but not made. So we can eliminate choices C and D.
Now, let's analyze the photosynthesis equation so we can pick between A and B.
6CO₂+6H₂O+light energy ⇒ C₆H₁₂O₆+6O₂
A gas (carbon dioxide), a liquid (water) and energy are used to make glucose and oxygen.
No solids are used, so we can eliminate choice A. We are left with choice B. Photosynthesis creates glucose using energy, a gas, and a liquid.

Predicting how the utilization of nonrenewable resources impacts the dom in the deep ocean
system?
Answer:
Non-renewable energies such as those derived from oil affect the seabed in a serious and lethal way for its fauna / flora.
When oil fields are drilled or when they have losses, they flood the seas with oil, these seas, having living organisms, will be directly affected in a lethal way by this unexploited fuel.
In addition, petroleum derivatives such as naphtha are used for water cars such as boats that pollute the water
Explanation:
Environmental awareness led to the search for an alternative as a source of energy that are renewable sources, which make a lot of competition today to polluting or non-renewable sources.
In addition, it must be considered that the pollutants have a limit, since they are exhausted, and on the other hand, an economy that solvent and supports all the expenses of the extraction of these from the depths of the seas is needed.
Answer: When coal and oil are burned, they release particles that can pollute the air, water, and land. ... Burning fossil fuels also upsets Earth's “carbon budget,” which balances the carbon in the ocean, earth, and air. When fossil fuels are combusted (heated), they release carbon dioxide into the atmosphere.
