Water is the most abundant molecule in the body, but it is not a biomolecule. Neither are carbon dioxide,
ethanol, or methane. Review the definition of a biomolecule and the structure of these biomolecules
compared to glucose and alanine, and explain why glucose and alanine are important and common
molecules are not biomolecules.
A biomolecule is one that is created by a living thing by definition. Water is therefore the external supply of carbon dioxide that living things use to manufacture proteins to fulfill their energy needs.
Water molecules have a slightly positive and a slightly negative side as a result of the unequal sharing of electrons.
There is neither a positive nor a negative side to some molecules, as ethane.The unequal distribution of electrons within the polar molecule is what distinguishes polar (water) from non-polar (ethane) molecules. Covalent bonds in nonpolar molecules have an equal number of electrons.Within aqueous solutions, water is universalizing everything formed from atoms and molecules.Molecules of two or more substances are combined in a homogenous manner to form solutions. Typically, the chemical with the highest concentration is the solvent. Some chemicals are soluble in little doses.Learn more about biomolecules here:

One of the main reasons that the American diet is unbalanced
One of the main reasons that the American diet is unbalanced is because of their high consumption of preserved or canned food and a diet that is rich in fats and calories.
A balanced diet must contain the following seven components: carbohydrates, protein, fat, fiber, vitamins, minerals, and water.Maintaining good health and feeling your best can both be facilitated by eating a healthy, balanced diet. To acquire and maintain a healthy body weight, this entails consuming the appropriate amounts of food and drink, as well as a wide variety of meals in the appropriate quantities.Foods that have been preserved and are not truly fresh are referred to as processed foods. Processes that involve the addition of preservatives include canning, smoking, salting, and curing.Because processed meals are frequently easier to find than fresh foods, many consumers choose them over fresh produce. Fresh goods might occasionally be more expensive than their processed equivalents.Hence, the American diet is unbalanced because of their consumption of processed food.

Studying the folding patterns of protein molecules can help microbiologists better understand cellular processes as well
as some diseases, such as Alzheimer's, that are caused by proteins that have misfolded. The folding of these
complicated molecules can be simulated on computers, but it takes a lot of processor power and time for even
expensive supercomputers to do this.
A group of researchers at Stanford University developed software that can be used to distribute the processing of data to
anyone who is willing to donate time on their idle personal computers. As a result, the researchers have been able to
achieve protein-folding simulations that are far better than those other computing methods have done. Which statement
best describes the work of these researchers?
Running an experiment required the researchers to use ingenuity to tackle an issue.
The correct answer is "Running an experiment required the researchers to use ingenuity to tackle an issue."
It is the best choice since researchers can process data on anyone's computer who wishes to lend it to them, thanks to software that scientists created. In other words, they came up with a clever solution to the time and financial constraints that the simulation of these proteins folding had.Since the data can be replicated using the program, the work qualifies as scientific, and the fact that the data were not processed in a single location does not change this.The researchers employed more than just tried-and-true scientific methods. It is not a proven scientific method for anyone to be able to contribute time from their computer using software.In conclusion, the answer given above is the best one. Scientists employed ingenuity to find a solution; otherwise, it would have cost time and money to slow down or cease the research.To learn more about protein molecules visit:

Giving brainiest to whoever helps me with this question. (Very Hard)
Answer:
Basically you need to get several goldfish and different containers that are a different water temperature.
Explanation:
Get your goldfish. About 3-4 because the water should affect each of them about the same, so you want to make sure that it is the same outcome each time and not just a fluke.Get your water containers. Ideal water for goldfish is about 68-74 degrees. Anything below 68 is considered to cold, and anything about 74 degrees would be considered to hot. However, with this experiment, you will need "cold" water (anything under 67 degrees ideally anything under 55 degrees would be nice and "cold" for the fish), ideal water (68-74 degrees), and then "hot" water (anything above 75 degrees. Ideally about 77 - 85 degrees would be hot enough for them)Next I'd say form your hypothesis. When water is too cold, goldfish may stop eating, begin hibernating or die. When the water is to hot goldfish will become very stressed, and can overheat and die. So, choose a hypothesis from that.Your independent variable would be the water temperature, because it doesn't depend on anything. While how your goldfish act would be the dependent variable because they act according to the water temperature.Good luck with your experiment, and this is all I got for ya! Good luck!

Analyze and evaluate how natural selection produces change in populations as opposed to individuals
Answer:
For natural selection to work there must be variation in the population for it to act upon and so ‘choose’ the most fit genes for a particular situation. Populations tend to produce more offspring than the environment can support, and the inevitable consequence of this overproduction of offspring is a struggle for survival. Natural selection creates these selection pressures so the organisims best suited for the environment are more likley to survive and therefore pass on their genes to their offspring.
Natural selection can only happen in a population rather than an individual becasue it is the whole population's characteristics culmalitvley changing to better suit the environment. By passing down favourable traits to their offspring. It cannot happen in an individual because they cannot change their traits to better suit the environment, only pass on their traits to their offspring. A change due to natural selection can take generations

2 diff ways antibiotics work against bacteria
Answer:
There are two main ways in which antibiotics target bacteria. They either prevent the reproduction of bacteria, or they kill the bacteria, for example by stopping the mechanism responsible for building their cell walls.
Answer:
Antibiotics can kill bacteria by:
1. Preventing the production of peptidoglycan that forms the cell wall. The cell will continue to grow without developing new cell wall, this causes the already existing cell wall to get weaker which will eventually cause the cell to rupture.
2. Stopping the production of proteins (protein synthesis) which prevents the production of new DNA
