What are the pros and cons of CRISPR-cas9
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.

Definition: These are the standards that determine a scientists behaviors, right or wrong
Example: Is stem cell research right or wrong?
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.

A solution with the indicator would turn from yellow to blue when which combination of factors exists?
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.
Explanation: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.

How dark coat colored mutation can be an advantage to some mice and disadvantage to others
Answer:
theyd most likely be able to adapt to the environment they are in and there would be natural selection involved
Explanation:
Based on the information in the table, which of the following changes is least likely to produce a phenotypic
change in an organism?
A. GAU to GGU
B. GAU to GUU
C. GAU to GAA
D. GAU to GAC
GAU to GAC is least likely to change phenotype of an organism.
Explanation: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

Explain the process of sexual reproduction in angiosperms.
Answer:
Process of sexual reproduction in angiosperms: There are two processes which are involved during sexual reproduction i. e. Pollination and fertilization. In pollination, the pollen of stamen falls on the stigma of carpel where they make a tube towards ovary where ovule is present. When the pollen reaches the ovary and fuses with ovule, it produces zygote which turns into seed, this process is called fertilization.
Angiosperms are the flowering plants that produces offspring by the process of se-xual reproduction.
Se-xual reproduction in angiosperms:The form of reproduction in which genetic material is required from both the parents is known as se-xual reproduction. The parent plants possess female and male se-x cells known as gametes. The male and female gamete combine to give rise to offspring by the process of fertilization.
The se-xual reproduction in angiosperms or the flowering plants takes place by the process of pollination. The flowers comprise female se-x organs known as pistils and the male se-x organs known as stamens. The part of the stamen, which comprise pollen is known as anther. The pollen is required to move to the part of the pistil known as stigma.
Plants can either cross-pollinate or self-pollinate. Pollinators refers to the animals or the agents that carry the pollens to the stigma in the plants. After pollination, the next step is fertilization. After reaching the pistil, the pollen requires to fertilize and egg within the stigma, this egg is known as ovule. The process of fertilization give rise to the fruits that comprise seeds.
Thus, in the angiosperms, the process of se-xual reproduction in order to produce the offspring.

How do the number of chromosomes in cells that go through meiosis and mitosis compare?
A.
Cells that go through meiosis have half as many chromosomes as cells that go through mitosis.
B.
Cells that go through meiosis have one-fourth as many chromosomes as cells that go through mitosis.
C.
Cells that go through meiosis have twice as many chromosomes as cells that go through mitosis.
D.
Cells that go through meiosis have four times as many chromosomes as cells that go through mitosis.
Answer: Option A is correct.
Cells that go through meiosis have half as many chromosomes as cell that go through mitosis. Meiosis is that's why called REDUCTION DIVISION.
Explanation:
In meiosis, the number of chromosomes becomes half or reduced than the normal while, in mitosis the number of chromosomes remains the same.
In meiosis, daughter cells have half the number of chromosomes compared to those produced in mitosis. Therefore, the correct answer is A. Cells that go through meiosis have half as many chromosomes as cells that go through mitosis.
The correct answer is A. Cells that go through meiosis have half as many chromosomes as cells that go through mitosis.
Before meiosis begins, the parent cell is diploid, with 46 chromosomes.After meiosis, four haploid cells are produced, each with 23 chromosomes.In mitosis, the parent cell also starts with 46 chromosomes, but after division, each of the two resulting cells retains 46 chromosomes.This means that meiosis reduces the chromosome number by half, while mitosis maintains the same chromosome number.Why Other Options Are Incorrect
Option B: Cells that go through meiosis do not have one-fourth as many chromosomes as cells that go through mitosis; they have half.Option C: Cells that go through meiosis do not have twice as many chromosomes as cells that go through mitosis; they have half.Option D: Cells that go through meiosis do not have four times as many chromosomes as cells that go through mitosis; they have half.3. a. Reviewing How does a mutation in a gene
affect the order of DNA bases?
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.
When excess sugar is produced in a plant , the plant will
Answer:
Store it as starch
Explanation:
When a plant produces too much sugar during photosynthesis, it is transported through the phloem and is stored as starch in the roots. It can then be turned back into sugar when the plant needs it.
A plant with excess sugar will store it in the form of starch or glycogen in its tissues which can be used for energy later. The sugars are transported from where they are produced (sources like leaves) to where they are needed (sinks like roots and fruits) across the plant.
Explanation:When a plant produces excess sugar, it has mechanisms in place to utilize this surplus. The sugar serves as a vital source of energy, critical not only for immediate physiological processes but also for the plant's growth and maintenance. In conditions of high light and temperature, such as in C4 plants like maize and sugarcane, the production of sugar can be significantly higher when compared to C3 plants.
These sugars generated via photosynthesis in the leaves, which act as sugar sources, are allocated across the plant body to areas known as sugar sinks. Sinks are parts of the plant such as roots, stems, and developing fruits and seeds that need external sugar supply to meet their energy requirements. When reserves are abundant, excess sugars can be stored in the form of compounds like starch or glycogen, which provide a reservoir of energy that the plant can draw upon in times of scarcity or during the night when photosynthesis is not possible.

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
