Answer:
The correct answer is -
1. right-handed
2. right-handed
3. positive
4. left-handed
5. negative
6. negative
Explanation:
In a circular bacterial chromosome, the structure of DNA is a right-handed double helix In a circular bacterial chromosome.
If DNA is twisted in the right-handed direction, it becomes overwound. Overwinding results in positive supercoiling takes place. If DNA is twisted in the left handd direction, it becomes underwound. Underwinding results in negative supercoiling.
f. One effect negative supercoiling in bacterial chromosomes is to promote separation of the two strands of DNA in the double helix

See explanation
Explanation:
We inherit our blood groups from both parents. Our blood type is controlled by a single gene. This gene displays 3 different allelic pairs which must include A, B or O. A child is expected to receive one of the three possible allelic pairs from each of the both parents. This means that there are six possible genotype and four possible phenotype for the child.
Given that Christopher's parents (Andersons) are AB and O,Christopher can have a B blood group.
Given that John's parents (Browns) are A and O, it explains how John can have blood group A.
Given that The Christiansons are A and AB, they can give birth to Robin whose blood group is AB.
Since the Dietrichs are O and O, the only possible blood group of their child is O, hence they are definitely the parents of Jane.
The answer to this question would be soft agar plate.
The semisolid medium tube is mostly used for containing the specimen. It is hard to examine semisolid medium since the bacteria can grow in the upper part, middle part or even the lower part of the medium. In agar plate, the bacteria always growth in the upper part so it is easier to count the bacteria.
But semisolid can give some more information in determining whether the bacteria is anaerobic by looking for bubble inside the medium. Anaerobic bacteria can do fermentation that will produce air.
Answer:
The advantage of this is that there is a larger surface area exposed, more time available and shorter difference for exchange of oxygen.
Explanation:
<u>Answer</u>: Weber's/Weber-Fechner's law of just noticeable difference
This phychologoical law is used to quantify the perception of change for a given stimulus. The perceived change is proportional/constant ratio to the initial stimulus. Thus, it is the minimum amount of a stimulus intensity change that will produce noticeable variation in sensory experience.
As in the example, it has been shown that this law is not function very well for extremes of stimulation.
