Solution :
In this question we have to determine whether the statement given in the question is accurate or precise or both or neither of them.
In the question it is given that the lab members are making a guess about how many base pairs will the new plasmid will have. Their random guesses of base pairs are 4,005; 4,006; 4,007; and 4,010. But in actual, the new plasmid has 7,968 number of base pairs.
Therefore, according to it, the data in the statement is precise but it is not accurate.
Precision refers to the degree of the reproducibility of measurements even if the values varies from accepted values. And accuracy shows how much close the measurement is to the accepted or the known value.
We say that we have a precise data on our hands and not an accurate one
Option B
AccuracyQuestion Parameters:
The lab members' guesses are 4,005; 4,006; 4,007; and 4,010.
Generally, accuracy shows how close a size is to a regarded or established value, whilst precision in facts capability the degree of reproducibility of the measurements. Measurements that are each specific and correct are repeatable and very close to genuine values.
Hence, we say that we have a precise data on our hands and not an accurate one
Option B

Why scientific naming is necessary?
Answer:
The correct answer would be - to communicate unambiguously globally.
Explanation:
In different locations on the earth or countries, there are thousands of languages present, and each language has a name for the different species or different organisms that leads to confusion and tough to take the record.
Therefore, there is a two-part scientific name system proposed for every species first name for the genus and second part for the species, it is called "binomial nomenclature." It helps and allows to communicate unambiguously about the species of different organisms globally.

Cross two heterozygous black mice and tell the possible phenotypes and
genotypes in their offspring.
Answer:
Phenotype: 3 black mice: 1 brown mice
Genotype: 1 BB: 2Bb: 1bb
Explanation:
This question involves a single gene coding for fur color in mice. The allele for black color (B) is dominant over the allele for brown mice (b). This means that a mouse that is heterozygous will be black.
If two heterozygous black parents are crossed i.e Bb × Bb, the gametes produced by each parent are: B and b. Using these gametes in a punnet square (see attached image), the following offsprings will be produced:
BB, Bb, Bb, and bb
- The phenotypes of this cross is 3 black mice: 1 brown mice
- The genotypes of the cross is 1 BB: 2Bb: 1bb

Which object made up of one or more smaller unit objects would make the best model for a group of cells from a plant?
Answer:
D. Dresser
Explanation:
According to the unified cell theory "all living organism are made of one or more small cells" and new cells arise from one cell through cell division.
From the given examples, the best model for a group of cells from a plant is "dresser" because a cell is consist of small structures called organelles that perform specialized functions likewise a dresser can contain several objects that can act as organelles.
Hence, the correct answer is "D. Dresser".

Occasionally a new resistant strain of pathogen appears. The new strain may spread rapidly. Explain why
Answer:
Antibiotics are not effective for new strains and so new resistant pathogens survive and reproduce, which leads to the increasing population of resistant pathogens and spread rapidly.
Bacteria can evolve and adapt themselves quickly as they are able to reproduce at a fast rate. Mutations of bacteria produce new strains that are resistant to certain antibiotics, such as penicillin, and cannot be destroyed by the antibiotic so they spread more rapidly.
Glucose consists of carbon, oxygen and hydrogen atoms. What happens to these atoms
during glycolysis?
a) Nothing, glycolysis does not affect the glucose molecule
b) The atoms are converted into other molecules in a series of chemical reactions
c) The atoms are transformed into energy
d) All atoms are transformed into other atoms in a series of chemical reactions
Answer:
b.
Explanation:
the atoms are converted into other molecules (pyruvate) in a series of chemical reactions
Glucose consists of carbon, oxygen and hydrogen atoms. The thing that happens to these atoms during glycolysi is that The atoms are transformed into energy
Glucose is a type of simple sugar that has six carbon atoms and during glycolysis, is broken down easily because it is a monosaccharide
Glycolysis is the process of breaking down and converting glucose into CH₃COCOOH.
Therefore, what happens to carbon, oxygen and hydrogen atoms during glycolysis is that they are transformed to energy

D. Age of organisms when they died
Answer: changes in climate
Change in climate information that fossils in samples from Earth's crust reveal about Earth's history. So, the correct option is (A).
What are Fossils?A fossil is defined as the preserved remains, impression, or trace of a once-living thing from a past geological age, including bones, shells, exoskeletons, fossilized traces of animals or microbes, amber, hair, petrified wood, and DNA. The totality of fossils is known as the fossil record.
There are five types of fossils which are as follows:
Body FossilsMolecular FossilsTrace FossilsCarbon FossilsPseudo fossilsThe fossil record shows that the types of living things on Earth changed over time which reveals the Earth's history.

How may mRNA be modified before it leaves the nucleus?
Answer:
The pre-mRNA molecules undergo three main modifications. These modifications are 5' capping 3' polyadenylation and RNA splicing which occur in the nucleus before RNA is translated.
Explanation:
mRNA compares to the hereditary succession of quality, and is perused by a ribosome during the time spent combining a protein.
How mRNA can be modified?it should go through extra handling before it leaves the core. This might incorporate joining, altering, and polyadenylation. These cycles adjust the mRNA in different ways. Such alterations permit a solitary quality to be utilized to make more than one protein. Exons are segments of mRNA which become "communicated" or converted into a protein. They are the coding bits of a mRNA atom.
