Please describe the bioinformatics tool, the database, and the procedure you would use to find such information. Give two possible outcomes of your search.
Answer:
The summary of the question has been summarized throughout the explanation segment below.
Explanation:
BLAST seems to be the most commonly utilized sequencing correlation platform. BLAST seems to be a methodology as well as an operation for the comparison of primary physiological sequence data. Instead with BLAST, we're going enough to get some successfully predicted gene mutation new variant. Look for, racial identity percentage points and sometimes even E Value percentage points lookup pattern.This should start giving extensive information such as which life forms the component has been transcribed. And we'll get documentation about everything from the gene, exon, and so on., connection to the enzyme interpretation.

Question 18 of 20 :
Select the best answer for the question.
18. How has the use of herbicides affected agricultural productivity?
O A. Fewer pesticides are needed because of parasitoids.
OB. Fewer people are needed to weed because of herbicides.
O C. Fewer crops are produced because of herbicides.
O D. Fewer crops are organic because of the use of Bt toxin.
O Mark for review (Will be highlighted on the review page)
Answer:
B. Fewer people are needed to weed because of herbicides.
Explanation:
Herbicides are chemical substances specifically used to control the widespread growth of weeds i.e unwanted plants. Using herbicides has been useful in eradicating the weeds that pose a great threat to agricultural productivity.
Since chemical control (herbicides) has proven to be a faster and effective method, fewer people are needed to involve in the physical control of weeds i.e. weeding. Hence, the use of herbicides has affected agricultural productivity by helping to reduce the amount of laborers.
The older crust in this case would be at point D, the newest at point A.
what type of rock would you expect to forming at point A?
Explanation:
New ocean crust is formed at the mid ocean ridges. The new crust is then pushed away from the ridge as newer crust comes to the surface. The ocean crust then spreads out enlarging the ocean. The farer away from the ridge the ocean crust is the older the crust
In actuality, the DNA sequence of the human genome is NOT random. Some sequences, including some very large sequences, are repeated many times throughout the human genome. Write two ideas you have for how this fact complicates the use of CRISPR gene-editing technology in humans.
Answer:
repeated DNA sequences decrease the target specificity of the CRISPR-Cas system, and may lead to off-target effects
Explanation:
The CRISPR-Cas system is a versatile and powerful tool for gene editing. This gene-editing tool consists of a single guide RNA (sgRNA) that guides the Cas endonuclease protein to the appropriate genomic locus, where Cas generate a double-strand break in the DNA and thus induces DNA repair either by Non-homologous end joining (NHEJ) or Homologous Recombination (HR) repair pathways. The sgRNA consists of a 17-20 nucleotide sequence which is complementary to the target DNA, this sequence is called crispr RNA (crRNA). The existence of repeated DNA sequences hampers the specificity of the CRISPR-Cas tool because a particular sgRNA is able to guide Cas9 to different genomic loci that have the same (repeated) nucleotide sequence complementary to the crRNA. In consequence, repeated DNA sequences may lead to undesired off-target effects, i.e., unintended cleavage (and therefore unintended mutations) at untargeted genomic sites.
1. Discuss how the study of fossils provides strong evidence for evolution. (13.2 and 13.3)
Answer:
in fossils we see homologous structures that suggest a common ancestor.
By looking at the bones of the arms and comparative anatomy we see the similar structure and function that is retained.
When looking at other animals like birds we see Analogous structures that look similar but have a different function (flying).
Finally we see Vestigial structures which are structure that no longer function as they once were used for. An example of this is the coccyx (tail bone in humans) compared to tails in dogs, cats, monkeys, etc.

Which of the following is used to screen for carcinogenic potential of various compounds?
transformation testing
replica plating
Ames test
ELISA test
Answer:
Ames test
Explanation:
This is because Ames test is a test that uses bacteria strain i.e Salmonella typhimurium to check or assess of a chemical has carcinogenic effect of it. It uses mutagenicity of bacteria. It is a biological assay that test whether an a chemical can cause mutations in the dna of the test organisms. When mutagens are added and also liver enzymes, there would be a reverse mutation and this will lead to their growth
When does transformation occur
Answer:
Transformation results in the genetic alteration of the recipient cell. Exogenous DNA is taken up into the recipient cell from its surroundings through the cell membrane (s). Transformation occurs naturally in some species of bacteria, but it can also be affected by artificial means in other cells.

Crickets "chirp" by rubbing their wings or legs over each other. This phenomenon is known as stridulation. It is a means by which male crickets "call" to females to communicate their interest in mating. Frequency refers to the number of chirps that crickets produce during a period of time. Some have suggested that you can tell the temperature and the humidity based on how fast crickets chirp.
Required:
a. What is the effect of temperature on the frequency of cricket chirping? As the temperature rises, the cricket chirp occurs more rapidly therefore increasing.
b. What is the effect of humidity on the frequency of cricket chirping? As the humidity rises, the cricket chirp frequency occurs more rapidly therefore increasing.
Answer:
a. As the temperature rises, the cricket chirp occurs more rapidly therefore increasing. It is correct.
b. As the humidity rises, the cricket chirp frequency occurs more rapidly therefore increasing. It is incorrect. The increase in humidity does not affect the chirp frequency in crickets.
Explanation:
As temperature increases, the frequency of cricket chirp increases too. After listening to the audios, we can see that in the first audio, where the temperature is 14° Celcius, the frequency is 24 chirps in 15 seconds. In the second audio, with 19° Celcius, the frequency is 28 chirps in 15 seconds. In the last audio, where the temperature is 24° Celcius, the chirp's frequency is 34 chirps in 15 seconds. In conclusion, if the temperature increases, the chirps' frequency increases too.
As humidity increases, the frequency of the chirp does not. In the three audios, the number of chirps in 15 seconds was 20. We can conclude that humidity does not affect the frequency of chirps frequency.
The cell membrane contains channels and pumps that help move materials from one side to the other. What are these channels and pumps made of?
Group of answer choices
carbohydrates
proteins
lipids
nucleic acid
Answer:
The correct answer is ''proteins.''
Explanation:
Transport phenomena are essential in living beings, either to carry a hydrophobic molecule through an aqueous medium (transport of oxygen or lipids through the blood) or to transport polar molecules through hydrophobic barriers (transport through the cell membrane). Biological transporters are always proteins. Proteins are capable of carrying out specific functions such as the selective transport of molecules, or certain enzymatic reactions, among others. Membrane proteins can be peripheral or partially or totally integrated into the membrane, being, generally, globular or fibrous. Its activity is essential for the maintenance of transmembrane gradients. Thanks to membrane proteins, the exchange of molecules such as nutrients or waste products takes place, as well as the reception of external signals. Among its functions are channel-forming: Integral proteins arranged in the membrane in such a way that they give rise to the formation of a pore or channel, usually hydrophilic. These pores or channels allow the entry and exit of certain substances from the cell.

Why are most genes inhibited in an average animal cell
Answer:
Most genes must be turned off because cells play specific functions, thereby only a limited number of genes must be expressed in each cell type in order to produce proteins required in the cell
Explanation:
Gener regulation is a critical molecular mechanism required for normal cell functioning. In consequence, genes are turned on and off depending on the cell type. For example, in the brain, cells that will be differentiated into neurons will be expressed, while genes involved in the differentiation of undifferentiated myoblasts into muscle cells will be turned off. Thus, genes are switched off in order to produce only those specific proteins which are required for each cell during specific developmental programs and functions carried out by each cell type.

Hello all. I really need help immediately with this question. Here is the question! Explain how these terms work together IN TRANSLATION: mRNA, tRNA, codon, amino acid, protein
Thank you sm for the help :)
Answer:
Translation takes place in 3 main steps: initiation, elongation and termination.
In initiation, the ribosome binds with the mRNA strand and a initiation complex forms. An initiator tRNA molecule brings the first amino acid, methionine. It binds with the start codon using its anticodon, UAC. The large ribosomal subunit then binds to the small ribosomal subunit.
In elongation, more charged tRNAs bring the amino acids to be added on the growing polypeptide chain. Elongation continues until the ribosome encounters the stop codon.
In termination, a release factor binds to the stop codon, causing the polypeptide to be released from the ribosome. The ribosomal subunits separate from the mRNA and from each other. The polypeptide undergoes folding to form secondary and tertiary structures to become a fully-functional protein.
Notes:
• Translation is the process by which a protein is synthesized from mRNA.
• mRNA: messenger RNA
• tRNA: transfer RNA
• codon: A 3-nucleotide sequence that codes for a specific amino acid. For example, AUG codes for methionine.
Select all that are true regarding ATP cycling
A. ATP is formed from ADP and phosphate
B. Energy for ATP synthesis comes from the oxidation of glucose and other fuel molecules
C. ATP hydrolysis is an endergonic reaction
D. Oxidation of ATP can be used for performing endergonic reactions in the cell
Answer:
A, B and D are correct
Explanation:
Adenosine diphosphate (ADP) can form a bond with a phosphate group to form Adenosine triphosphate (ATP), which is the most abundant energy carrier molecule in cells. An endergonic reaction is a chemical reaction where there is a net input of energy, while an exergonic reaction generates energy. ATP hydrolysis releases energy (conversely to ATP synthesis that requires an input of free energy), and therefore ATP hydrolysis is an exergonic reaction. ATP hydrolysis releases around 7.3 kilocalories per mole. In a coupled reaction, the energy released by ATP hydrolysis is used by the cell to carry out endergonic reactions in an exergonic manner (e.g., glucose phosphorylation, which is an energetically unfavorable reaction).
