Answer: The answer is a short amount of time
Explanation:
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.
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.

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.

I ONLY HAVE TODAY a student claims that model A shows winter in both hemispheres. Do you agree? Explain why or why not.
model A does not show winter in both hemispheres. He shows the land without the slope and the meridians that divide them.Actually, the names for the hot season (summer) and cold season (winter) apply the same way in the Northern and Southern Hemispheres. What is different is when those seasons occur on the Jovian Calendar. Our northern winter is in Dec, Jan and Feb, whereas the southern winter is in June, July, and August.
What is the Earth's axis?The Earth's axis is an imaginary line that passes through the center of the Earth, going from the North Pole to the South Pole. The Earth moves around its imaginary axis, taking a total of 24 hours to complete the rotation.
What is parallels and meridians?The parallels are lines that run parallel to the Equator, which "cuts" the Earth in half, causing the division between the northern and southern hemispheres. The best known parallels are the Tropic of Cancer and the Tropic of Capricorn.

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.
100 POINTS!!! ANSWER ASAP [WRITE 5 SENTENCE ANSWER] If 2 objects have the same volume, but 1 has more mass than the other, explain if the densities of the 2 objects are the same or different. Why?
Answer:
Density is determined by an object's mass and volume. If two
objects take up the same volume, but have one has more mass, then it
also has a higher density. The density of a substance is the relationship between the mass of the substance and how much space it takes up (volume). Density equals the mass of the substance divided by its volume; D = m/v. Objects with the same volume but different mass have different densities.

A scientist is conducting research to see whether dogs or cats are more popular. He goes to a dog park and asks all of the owners which pet they prefer. 100% of those polled stated that dogs are their favorite animal.
This experiment is an example of:
A) personal bias
B) experimental bias
C) cultural bias
D) a controlled experiment
Answer:
C) Cultural bias
Explanation:
A cultural biased experiment is one which is based on the cultural views or perceptions. In this experiment where a scientist is trying to see whether dogs or cats are more popular, he conducted a questioning assessment from all the dog owners in a dog park.
He found that 100% (all) of them preferred dogs to cats. This preference is due to the to the culture of the dog owners who have a mentality of dogs being their best choice without exploring possibilities from other pet animals. The scientists goes to the dog park knowing that the dog owners will favour dogs over cats. Hence, it is a cultural biased experiment.

Answer:
B. Control group
Explanation:
Control groups provide a baseline for an experimental investigation. Thus, the correct option is B.
What is an Experimental investigation?An experimental investigation may be defined as a complete set of methodology that involves the active modification of certain variables in order to test a hypothesis and gather documented evidence to support the claim.
During an experimental investigation, a hypothesis is a previously occupied knowledge that requires complete sets of evidence. While independent and dependent are variables that should be modified in order to reveal the outcome.
Control groups are those standard values or ideas that assist the experimental study of one variable at a time irrespective of any external influences.

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.
