Answer:
It is +
Explanation:
Water molecules are polar, with partial positive charges on the hydrogens, a partial negative charge on the oxygen. So your solute would attract the opposite charge which is the Oxygen
Polar water molecules have partial positive hydrogen charges and partial negative oxygen charges. Thus, oxygen would attract your solute having positive charge.
What is polarity?Polarity is the separation of electric charge that occurs when a molecule or its chemical groups have an electric dipole moment. This results in the molecule or chemical group having one end that is positively charged and one end that is negatively charged. Because of the disparity in electronegativity between the atoms that are linked together, polar molecules are required to have one or more polar bonds.
Polar water molecules have partial charges in both the hydrogen (positive) and oxygen (negative) directions, though mostly in the hydrogen's favor.
Therefore, oxygen would be attracted to your solute if it had a positive charge.

Why does the chance of precipitation increase when the humidity is high
Answer:
When the humidity is high, moisture/water becomes easier to evaporate, making the clouds heavier, thus the chances of precipitation are higher.
When the humidity is high, the chances of precipitation increase because the amount of water vapor in the air increases. So, the correct option is D.
What is Humidity?Humidity is defined as the concentration of water vapor present in the air which is the gaseous state of water that is invisible to the human eye. Humidity indicates the likelihood of the presence of precipitation, dew, or fog depending on the temperature and pressure of the system of interest.
In humid climates, thunderstorms tend to produce heavier rain than normal winter rain because the moisture content in the air is higher in spring and summer, and since the wind usually forms more rapidly in thunderstorms than normal winter systems.
Thus, when the humidity is high, the chances of precipitation increase because the amount of water vapor in the air increases. So, the correct option is D.

You going on a trip to Europe you need to figure out how much money you should save for gasoline you have determined that while you are traveling in Europe you will cover about 325 miles how many kilometers will you be traveling?
Answer:
523.035 km
Explanation:
It is given that, a distance of 325 miles is covered on a trip to Europe. In this problem, we need to find how many kilometers will you be traveling.
To convert 325 miles to km, we must know the conversion from miles to kilometers.
1 mile = 1.60934 km
For 325 miles, multiply it by 1.60934 i.e.
325 miles = (325 × 1.60934) km
= 523.035 km
Hence, you will be travelling 523.035 km on a trip to Europe.
Based on the chart above, food sample A is most likely to be:
starch
simple sugar
lipid
protein
The correct answer is B. A simple sugar
Explanation:
The chart shows sample A contains Monosaccharides or simple sugars in the section "are these nutrients present" but does not contain substances such as starches, lipids, or proteins, which discards the idea that sample A is a protein, starch, or lipid. Moreover, this sample was positive in Benedict's Test that focuses on finding the presence of reducing sugars such as Monosaccharides.
According to this, it is likely sample A is a simple sugar because only substances that are simple sugars or contain a high amount of this substance are positive in Benedict's Test; moreover, the chart mentions this sample had monosaccharides, which is a synonym for simple sugars (substance with only one sugar unit).

Why might a person who is dehydrated from heat have blood that is hypertonic compared to a normally hydrated individual?
the heat the body absorbs affects the iron in blood directly
Explanation:
^^
Hi there! :)
Someone who is dehydrated has below-normal levels of water in the blood.
Blood that is hypertonic has a much higher concentration of dissolved solutes in comparison because of lower levels of solvents, or water in the blood.
In general, a hypertonic solution has a much higher concentration of solutes compared to a liquid inside or outside a semi-permeable membrane. Therefore, if one is dehydrated, their blood would have a much higher concentration of these solutes in compared to the amount of solvent (water) which would deem it hypertonic.

An electron
represents the average location of electrons as they travel around an atom's nucleus.
Answer:
An electron shell
Explanation:
An electron shell represents the average location of electrons as they travel around an atom's nucleus.
An electron shell may be considered to be the orbit of an electron around the nucleus of an atom.
Electrons orbit around the nucleus of an atom based on their energy levels. The shell closest to the nucleus has the lowest energy level and thus electrons with the lowest energy levels are found in this shell whereas the shell farthest from the nucleus and the electrons occupying these shells have the highest energy levels.
The shell closest to the nucleus is the K shell, followed by L, M, N and so on, having energy levels of 1, 2, 3, 4 and so on.
Each shell can contain only a maximum number of electrons given by the general formula, 2n²; where n is the energy level of the shell. For example, the K shell can hold up to 2(1²) = 2 electrons; the L shell can hold up to eight 2(2²) electrons = 8 electrons.
Each shell consists of one or more subshells, which by themselves also consists of one or more atomic orbitals.

Two agar plates, one containing the antibiotic streptomycin and one without antibiotics, are inoculated with E. coli. After incubation, the streptomycin negative plate has many bacterial colonies, while the streptomycin positive plate has only a few colonies. Samples of the colonies from the positive plate are placed on another positive plate, and after incubation many colonies grow. In this experiment, what is the selective agent?
Answer:
The selective agent according to the scenario of the experiment is the antibiotic streptomycin.
Explanation:
A selective agent is an environmental factor that has a dramatic impact on the mortality rate of any organism. In this scenario of the experiment, the antibiotic streptomycin is the selective agent because as described, after the incubation period of the two agar plates, the plate with antibiotic streptomycin only has a few colonies which proves that the antibiotic streptomycin since it had an impact on the mortality rate of the E. Coli bacteria.
Answer:
The agent chosen according to the experimental form is the antibiotic streptomycin.
The rapid, uncontrolled division of cells is called cancer. Identify the answer below that is NOT a
factor that can cause cancer.
O Solar radiation
O Family genetics
O Pesticides
O E. Coli Bacteria
Answer:
O E. Coli Bacteria
Explanation:
Cancer is a genetic disease caused by mutations (i.e., genetic changes) in the genes that regulate distinct cell functions such as, for example, proliferation and differentiation. There are many factors capable of causing mutations and therefore are associated with cancer. For example, ultraviolet (UV) radiation from the sun has been identified to be the main cause of skin cancer. Moreover, there are individuals that are inheritably prone to suffer specific mutations in cancer-associated genes (oncogenes). Finally, many pesticides are well-known to be mutagenic agents (e.g., 2,4-D, glyphosate, endosulfan, etc.) and thereby can lead to cancer.
You are observing an enzyme driven reaction. You add chemical X, which inhibits the reaction. If you add more substrate, the reaction rate approaches the Vmax of the uninhibited reaction. Furthermore, the structure of X is similar to the natural substrate. What kind of inhibitor is X?
Answer:
X is a competitive inhibitor.
Explanation:
X is a competitive inhibitor because it fights with the substrate for the active site of the enzyme. The active site is specific for a type of substrate, but as the inhibitor has a similar structure to the substrate, it can fit and not allow the substrate to interact with the enzyme and make its reaction. What we can do to do to keep having enzyme-substrate bindings is add more substrate to the solution, so there are more substrates than inhibitors, which leads to more products as a final result of the interaction between the enzyme and the substrate.
