<span> a. The creation is a solution. If you can dissolve powdered substances in water f</span>ully, it will result in a mixture called solution. Solutions are transparent while suspensions may look murky, which particles setting at the bottom of the container. In a solution, the powdered substance is the solute, and water is the solvent.

The creation is a solution.

In a solution, the powdered substance is the solute, and water is the solvent.

You can dissolve powdered substances in water, the results in the mixture called solution.

Suspensions look murky, solutions are transparent.

A hawk and an owl compete for the same food in the same food web . What is the most likely reason why they are both able to succ
Natalka [10]

Answer: Biodiversity

Explanation: Biodiversity is in all ecosystems and it's everywhere. The reason they can compete and both succeed is because of biodiversity, they are not stuck to eating one animal there are thousands of different types of animals and because of this their is enough to go around. However if their wasn't biodiversity and their food choice was limited one would fail if competing in the same ecosystem.

E) what are the be amino acids formed from this gene?
Elena-2011 [213]

Answer:Amino acids play central roles both as building blocks of proteins and as intermediates in metabolism. The 20 amino acids that are found within proteins convey a vast array of chemical versatility. Tertiary Structure of a proteinThe precise amino acid content, and the sequence of those amino acids, of a specific protein, is determined by the sequence of the bases in the gene that encodes that protein. The chemical properties of the amino acids of proteins determine the biological activity of the protein. Proteins not only catalyze all (or most) of the reactions in living cells, they control virtually all cellular process. In addition, proteins contain within their amino acid sequences the necessary information to determine how that protein will fold into a three dimensional structure, and the stability of the resulting structure. The field of protein folding and stability has been a critically important area of research for years, and remains today one of the great unsolved mysteries. It is, however, being actively investigated, and progress is being made every day.

As we learn about amino acids, it is important to keep in mind that one of the more important reasons to understand amino acid structure and properties is to be able to understand protein structure and properties. We will see that the vastly complex characteristics of even a small, relatively simple, protein are a composite of the properties of the amino acids which comprise the protein.

Essential amino acids

Humans can produce 10 of the 20 amino acids. The others must be supplied in the food. Failure to obtain enough of even 1 of the 10 essential amino acids, those that we cannot make, results in degradation of the body's proteins—muscle and so forth—to obtain the one amino acid that is needed. Unlike fat and starch, the human body does not store excess amino acids for later use—the amino acids must be in the food every day.

The 10 amino acids that we can produce are alanine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, proline, serine and tyrosine. Tyrosine is produced from phenylalanine, so if the diet is deficient in phenylalanine, tyrosine will be required as well. The essential amino acids are arginine (required for the young, but not for adults), histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. These amino acids are required in the diet. Plants, of course, must be able to make all the amino acids. Humans, on the other hand, do not have all the the enzymes required for the biosynthesis of all of the amino acids.

Why learn these structures and properties?

It is critical that all students of the life sciences know well the structure and chemistry of the amino acids and other building blocks of biological molecules. Otherwise, it is impossible to think or talk sensibly about proteins and enzymes, or the nucleic acids.

Describe how a measurement can be accurate but not precise?
morpeh [17]
You can have error both human error i.e eye balling a measurement to what looks close. and then you have inherent error the error that is already in the equipment i.e a 2 scales one can give a measurement of x when set to zero and if put it on a second scale you could get a measurement of y when set to zero because of calibration gravity etc things you cant control
