does anybody know the answer to these?

Answer: Kingdom

Explanation:

The linnaean system of classification used in taxonomy start from highest (most general category) to the lowest level as follows: Kingdom --> phylum/division --> class --> order --> family --> genus --> species.

Thus, since the first level (Kingdom) require species to have the least number of common features, the most species are found in it.

For instance: living organisms of all species are classed into just 5 kingdoms whereas over a billion species exist.

Answer:

It has incomparable advantages over other gene editing tools.

Explanation:

For example, the CRISPR-Cas9 system has more target sites than ZFNs and TALENs, and Cas9 has many variants that can be used in a variety of studies. Moreover, the system is extremely easy to use and can be executed in almost any laboratory.

The most important advantages of CRISPR/Cas9 over other genome editing technologies is its simplicity and efficiency. Since it can be applied directly in embryo, CRISPR/Cas9 reduces the time required to modify target genes compared to gene targeting technologies based on the use of embryonic stem (ES) cells.

Disadvantages of CRISPR technology: CRISPR-Cas9 off-target; The effect of off-target can alter the function of a gene and may result in genomic instability, hindering it prospective and application in clinical procedure.

Answer:

One of the major pros of crispr-cas9 is that it could potentially wipe-out many genetic diseases and could even be used to develop a successful cancer therapy.

The main con would be the ethics. In the future an individual could select their own desired traits for their offspring. The wealthy would have a larger advantage which could increase the social gap.

GAU to GAC​ is least likely to change phenotype of an organism.

Phenotype of an organism is defined as the physical characteristics of an organism. This phenotype is dependent on the genotype of the organisms. This means the phenotypic characters are actually the expressions of the genes of the organisms. Now the genes are expressed in form of codons that are the three nitrogen base sequences. Each codon codes for a particular amino acid which in turn polymerises to from the protein which actually forms the phenotype of the organism.

Now there are 20 amino acids and 64 codons. Thus there are more than 1 codons for a single amino acid. So, if a codon is replaced by another codon which codes for same amino acid, then the phenotype is least likely to be affected.

Both the GAU and  GAC​ codes for aspartic acid. So the phenotype won't be affected much by this mutation

Answer:

Ethics

Explanation:

Scientific ethics are a set of moral standards that help to define right and wrong, helping to guide decision making when carrying out scientific research.

Sometimes scientific ethics can be highly complicated and there is often no clear "right" and "wrong", which is why guidelines for best practices are extremely important with controversial research topics like stem cell research.

Ethics guides decision making from what research is allowed to be carried out (e.g. animal testing) to reporting of results (e.g. making sure that results are accurate).

Scientific ethics is so important, that there is an entire branch of biology dedicated to it, called bioethics.

Answer:

0.1450 meters

Explanation:

we know that

The magnitude of a quantity to a specific degree of accuracy is known as significant digits.

According to the multiplication and division rules of significant digits, the least number of the significant digit in any number of the problem determines the number of significant digit in the answer.

Remember that

[tex]1\ mm=0.001\ m[/tex]

so

[tex]145.0\ mm=\frac{145.0\ mm}{1\ mm}(0.001\ m)=0.1450\ m[/tex]

In 145.0 mm, there are 4 significant digits and in 0.1450 m. there are 4 significant digits.

so

The correct number of significant digits is 4

therefore

the correct answer is, 0.1450 meters

The Direct Coombs' test is a confirmatory test used to reveal the presence of blood with high accuracy. It identifies specific antibodies bound to red blood cells using hemagglutination, a process also employed in cross-match tests prior to blood transfusions.

The answer to the question, 'Which of the following is a confirmatory test used to reveal the presence of blood with high accuracy?' is the Direct Coombs' test. This test uses a special reagent known as Coombs' reagent to cross-link antibodies bound to red blood cells, facilitating hemagglutination. Hemagglutination is the clumping together of red blood cells - a process that will occur if a person has antibodies against certain substances.

Another type of test which makes use of hemagglutination is the cross-match test, carried out prior to blood transfusion. It entails mixing a small part of the donor's red blood cells with serum from the patient who is to receive the transfusion. If the recipient has antibodies against the donor red blood cells, hemagglutination will occur.

These tests help to ensure the compatibility of blood for transfusions and can be used to detect specific antibodies in a person's blood, thereby revealing the presence and quantity of certain bacteria or viruses. Therefore, they serve as important tools in medicine for accurate diagnosis and successful blood transfusions.

Explanation:

A solution would change from yellow to blue in response to alterations in pH, mainly due to the effect of an acid-base indicator. This color change represents a pH increase from acidic to alkaline conditions.

The solution would turn from yellow to blue due to changes in pH levels or chemical reactions. This kind of change generally occurs in an acid-base indicator which is sensitive to pH changes. The Henderson-Hasselbalch Equation assists in understanding the relationship between solution pH and its color. During color changes, pH levels determine the dominant form, either In¯ (indicator base form turning solution yellow) or HIn (indicator acid form turning solution red/blue). If we consider Bromphenol Blue as the indicator, its transition occurs from yellow (below pH 3), through green (pH 4-5.6), to blue (above pH 5.6). So, a solution would turn yellow to blue when pH is increased from below pH 3 to above pH 5.6.

Explanation:

Final answer:

A mutation in a gene alters the DNA sequence, potentially impacting the amino acid sequence of a protein. Substitutions may have minimal or significant effects, while insertions or deletions can lead to frameshift mutations with extensive consequences.

Explanation:

A mutation in a gene can result in changes to the order of DNA bases. Three common types of mutations are substitution, insertion, or deletion. In the case of substitution, one base is replaced by another, which may or may not affect the amino acid sequence, depending on whether the new codon codes for a different amino acid or the same one (due to the redundancy in the genetic code).

An insertion or deletion can have more drastic effects. These mutations can lead to a change in the reading frame, known as a frameshift mutation, potentially altering the entire amino acid sequence downstream of the mutation. For example, consider the sequence 5'-ATGGCAATCCTCAACGCTGT-3'. If an insertion occurs after the start codon AUG, this addition could shift the reading frame and change the way codons are read, thereby changing the amino acids encoded by these codons.

The effect of a mutation on the protein's amino acid sequence depends on its location and type. Using Figure 19.14 "The Genetic Code" as a reference, one can predict the specific consequences for the protein sequence. In the example of a substitution from AUU to AUC, this would be a silent mutation since both codons code for the amino acid Isoleucine. However, if the mutation results in a codon for a different amino acid or a stop codon, it could lead to a missense or nonsense mutation, respectively, dramatically impacting the protein structure and function.
