Answer:
The best answer is c).
Explanation:
According to the Big Five personality traits, someone who scored very low in extraversion will show resistance to attend crowded places (they prefer solitude) and is unlikely to engage in small talks. Thus we can infer that Jennette is not really interested in the dance, and she will not attend. However, <u>if she does</u>, it will probably be due to peer pressure and might feel uncomfortable most of the time.
1. Samples of a microbial colony obtained from the natural environment are not pure culture. They are mixed cultures because the environment consists of an array of microorganisms and not one specific organism. A sample obtained from the natural environment such as water or soil may contain several species of microbes that need to be further isolated to obtain a pure culture.
2. Isolation streak plate technique involves the dilution of the sample several folds and then streaking a small amount using a sterile inoculation loop on an agar plate in a zig-zag manner. This is done to obtain a pure culture of bacteria from a mixed population by separating the microprocessor. When the sample is diluted into a small concentration and is streaked onto agar placed, widely spaced, discrete colonies of bacteria can be observed. These isolated colonies can be further cultured to obtain pure cultures by picking and re-streaking them on fresh agar plates.
3. A microbial colony is considered a pure culture because it consists of single species. A single species of bacteria cluster and form an isolated colony on an agar plate which can be further plated on fresh medium.
3-1 - If your agar plate shows discrete uncluttered colonies then you have obtained an isolated colony. The following picture might help you to understand.
3-2. If you subculture isolated microbes into a sterile nutrient broth without any contamination, it will still be considered pure culture because it is single isolated species in a sterile aseptic environment of the nutrient broth.
3.3. A pure culture can become a mixed culture due to contamination. This could be caused by airborne bacteria if your conditions are not aseptic. Contamination is possible if the work area is not clean and sterile or if the glassware is not sterile. The contamination can transform your pure culture into a mixed culture and is hence problematic. So, it is very important to maintain a sterile and aseptic environment, glassware, and instruments.

Assuming this is a true or false question this is false. Children in high-pressure environments are more likely to bring guns to school.
For example, A child who excels in h=their classes and they are constantly being pressured by the school and their peers to be the best in the school is more likely to be frustrated and make irrational decisions due to the high pressure and stress.
Answer:He has a disorder known as hemophilia.
Explanation:
Hemophilia is a non common disorder that causes your blood not to clot normally due to the lack of blood clotting proteins.
If you get involved in an accident you may bleed more than usual however the most concern with this condition is the fact that a person can suffer from internal bleeding if their case of hemophilia is severe.
Internal bleeding may have an impact on your organs or be life-threatening.
Hemophilia is a genetic disorder which means it can be pass from your parents to you .
How is it treated ?
It is treated by regularly minimising the replacement of a specific clotting factor.
Symptoms
Symptoms depends on whether your case is severe or mild
If is severe you will bleed heavily and constant but if it is mild it happens only in few times.
One will bleed severely after surgery or dental work , more than a normal person would bleed .
Nose bleeds without being hurt by anything , swelling joints,large and deep bruises and heavy constant bleeding after vaccination.
blood in your urine or stool.
Answer:
A planet is round because of gravity. A planets gravity pulls equally from all sides
Explanation:
Gravity pulls from the center to the edges. This makes the overall shape of a planet a sphere
