The currently accepted model of the coeur laboratory you are observing skin cells labeled 'defective' to determine what is wrong with them. After careful observation you notice that the cytoskeleton is there, but the cell is still having trouble maintaining its shape. Infer what could be damaged.l membrane was discovered by
Answer:
Cell membrane
Explanation:
The cytoskeleton is known to be a kind of proteinous filaments which is found in the cytoplasm of organism but grow out to the cell membrane to give shape to the organism and likewise help in movement.
In the case highlighted above, the organism might still not be able to get a shape especially when the cell membrane is affected or being damaged.
Rosa made a chart to summarize the characteristics of two types of social behavior. Which headings best complete the chart? X: Herding Y: Cooperative Hunting X: Flocking Y: Migrating X: Cooperative Hunting Y: Herding X: Migrating Y: Flocking
Answer:
Flocking (birds) and cooperative hunting (lions or wolves)
Explanation:
In large animal groups, social behavior enables to obtain an evolutionary advantage over non-social species by making decisions that are likely to be beneficial for the group. In humans, a comprehensive understanding of these benefits has shown to be useful in different areas ranging from social to economic systems.
Cooperative Hunting is a social behavior that enables predatory social species like lions to hunt larger organisms, thereby improving the adaptive fitness of individuals.
Bird flocking is another type of social behavior in which a group of bird is in flight. This behavior is shared by very different species such as insects and fish. Flocking has shown to be beneficial to individual birds to take care of predators and to find food.

In a songbird species, defending a territory saved the bird 584 calories a day in reduced foraging activity, but cost the bird 656 calories in defense of the territory. Is defending the territory consistent with the prediction from optimal foraging theory, and what can explain this
Answer:
The correct answer is "No, this is not consistent with the predictions on optimality".
Explanation:
The optimal foraging theory (OFT) establishes that an organism looks for the best foraging strategy, which involves maximizing the amount of energy that is available in its daily activities. In this case, the songbird species is not consistent with the predictions on optimality since it needs more calories than it intakes in order to defend its territory. In this scenario, the songbird will lose 72 calories per day.
Which bacteria is Acid-fast?
Answer:
try and sum it down to 3 answers
Explanation:
With the use of site-directed mutagenesis, hemoglobin has been prepared in which the proximal histidine residues in both alpha and the beta subunits have been replaced by glycine. The imidazole ring from the histidine residue can be replaced by adding free imidazole in solution. Would you expect this modified Hb with free imidazole to exhibit oxygen binding? Why or why not?
Answer:
The modified hemoglobin with free imidazole cannot be expected to show cooperativity in oxygen binding. The movement of iron ion takes place up in the plane of heme when binding of one subunit of hemoglobin takes place with oxygen. One of the iron's and oxygen's axial ligands comprise the proximal histidine's imidazole ring.
With the movement of iron into the hemoglobin ring, the pulling of proximal histidine takes place along with it. Therefore, when binding of oxygen takes place with one subunit, a modification also takes place in the intersubunit associations, this also comprises displacement of the alpha helix. This phenomenon plays an essential role in modifying the hemoglobin's tensed state to the relaxed state. The withdrawal or mutation of the imidazole ring from the histidine residue does not further permit the cooperative binding as it is not associated physically with the alpha-helix.
Which statement regarding the "Krebs bicycle" is true? A) Ultimately, it results in the transport of NADH from the mitochondrial matrix to the cytosol. B) The urea cycle and the citric acid cycle have common cycle intermediates and are thus linked. C) Ultimately, it results in the transport of glutamate from the cytosol to the mitochondrial matrix. D) It requires a set of reactions known as the aspartate–argininosuccinate shunt.
Answer:
The correct answer is option D. It requires a set of reactions known as the aspartate–argininosuccinate shunt.
Explanation:
The Krebs bicycle is made out of on the right side the urea cycle, which networks with the aspartate-argininosuccinate shunt of the TCA cycle present on the left side. By argininosuccinate lyase, Fumarate delivered in the cytosol of the urea cycle enters the Krebs cycle in the mitochondrion and is changed over in a few stages to oxaloacetate.
Oxaloacetate gets an amino gathering with the help of transamination from glutamate, and the aspartate formed and leaves the mitochondrion and gives its amino gathering to the urea cycle in the response of argininosuccinate synthetase activity.
Thus, the correct answer is option D. It requires a set of reactions known as the aspartate–argininosuccinate shunt.
Biochemical changes in the body, that affect the rate of metabolism and elimination of a substance from the body and produce increased amounts to achieve the desired effects, may lead to development of
Answer:
Tolerance
Explanation:
Tolerance is the capacity of an organism to survive changes in certain environmental and biochemical conditions. It has to with changes an organism is able to withstand when is subjected to certain factors which can biotic or abiotic.
For example, in the consumption of alcohol, tolerance can occur when there is a fast elimination of alcohol from the body system. This is usually as a result of the activation of a group of enzymes that is responsible for the metabolism of alcohol in excessive alcohol drinkers. The activation of this enzymes increases the catabolism of alcohol and hence reduces the active time within the body, hence reducing the time by which alcohol intoxicates.
Tryptophan is an amino acid necessary for E. coli survival and growth. E. coli contain genes coding for enzymes that synthesize tryptophan. These genes are grouped together on a segment of DNA called the tryptophan (trp) operon. Cells can use these enzymes to synthesize tryptophan when it is not present in the environment. owever, when tryptophan is already present in the environment, cellular resources are shifted away from manufacturing the enzymes for tryptophan synthesis. Tryptophan binds with and activates the trp repressor, which then binds to the trp promoter and blocks RNA polymerase. Blocking RNA polymerase decreases the normal transcription rate of the operon. What type of regulation does the trp operon exhibit?a. positive regulation b. protein modification c. negative regulation d. translational regulation
Answer:
The correct answer is - The tryptophan operon shows C. negative regulation.
Explanation:
Tryptophan is an amino acid, excessively synthesized by the organism, it regulates its transcription through “trp Operon.” In this operon, the corepressor of the tryptophan binds to the repressor protein and gets activated.
This activated repressor now binds to the operator site, and prevents the binding of RNA polymerase enzyme and inhibits the protein synthesis.

If it is accepted that the information for how a protein is intended to fold lies within its primary sequence, explain why a purified protein denatured in vitro might not be able to renature accurately.
Answer:
Denaturation and renaturation are properties of protein but in some cases denaturation is irreversible and protein is unable to renature.
The primary sequence of a protein determines which portion of protein fold closely together in order to form three-dimensional conformation and the conformations are held by hydrogen bonds.
Denaturation of protein in-vitro is generally obtained by increasing temperature. Heat or high temperature disrupts hydrogen bonds that held between protein folds because high temperature increases the kinetic energy and the bonds are disrupted due to rapid heating. Disruption of hydrogen bonds will change the 3D structure of the protein and denatured proteins lose its function.
Chemicals are also used to disrupt hydrogen bonds such as alcohol.
So, high temperature and chemicals denature protein by affecting the hydrogen bonds holding 3D shape of primary sequence in protein and the change in protein becomes irreversible.
The fact that there appears to be a genetic component to inflammatory bowel disease, but that it does not show clear Mendelian inheritance ratios suggests any of the following, EXCEPT: the gene for the disease has incomplete penetrance. the gene for the disease has limited expressivity. the disease is polygenic. the gene for the disease is recessive.
Answer:
Option D
Explanation:
(the gene for the disease has incomplete penetrance. the gene for the disease has limited expressivity. the disease is polygenic) - all these are examples of non-mendelian inheritance which include incomplete penetrance, polygenic inheritance etc. These do not follow the mendelian pattern of inheritance.
(the gene for the disease is recessive.)- this shows the mendelian pattern of inheritance... Dominant and recessive characteristics are examples that show Mendelian inheritance.
Fungi are a necessary evil to humanity. Discuss the pros and cons.
Answer:
Fungi are said to be a necessary evil for society because:
On the one hand it has many pros, this means that they are used with optimal fines or that they benefit the human, such as yeast and alcoholic fermentation, the processes of beer formation, the production of basic foods for human nutrition , subsistence with the commensal or own flora of the human organism that defends us from other pathogenic microorganisms and really lethal for our species, and lastly they are also very good when it comes to scientific discoveries or advances, a great example is the penicillium fungus which is responsible for forming penicillin which is a very effective antibiotic today for a wide spectrum of bacteria.
On the other hand, the cons that some variety of fungi experienced lethal pathologies for humans such as histoplasmosis, or extremely dangerous pneumonia / bronchitis that today do not have a preventive method such as vaccines.
Explanation:
The fungi kingdom is extremely broad, that is why this kingdom can offer benefits or harm us human beings, and that is because the versatility of fungi is very high.
Nowadays, fungi present not only a difference in their morphologies, but also other resistance mechanisms, or tolerances to oxygen, metabolisms, energy sources, etc.

1.what could be the outcome of the Gram staining reaction
2.what could be this bacterium and why
Answer:
It could be a Staphylococcus or also called Staphylococcus, due to the disposition it presents.
Explanation:
Staphylococci are coconuts (rounded shape) that unite in the form of a bunch of grapes, this is characteristic of them.
It could become a Staphylococ Aureus, since these are usually associated with the most frequent infections in humans, but the possibility that it is another type of the same bacterial family is not ruled out.
Which type of mutation results in a frame shift mutation? Check all that apply? Substitute Insertion Deletion Point mutation
Answer: Insertion, Deletion
Explanation:
The frameshift mutation can be defined as a genetic mutation that is caused by the deletion or insertion of the DNA sequence or base pairs that shifts the sequence to be read. As a result of this the abnormal proteins are produced along with incorrect amino acid sequence that either shorter or longer than the normal protein.
molecular genetics experiment: In what way do the percentages of yellow leaves vary between dishes on Day 2? How do you account for this difference? Compare the percentage of yellow seedlings in dish 2 on day 2 with the percentage on day 4. What is the difference? What experimental variable accounts for this difference? How can you account for the difference between the seedlings in dish 1? Is the yellow color genetically or environmentally controlled? How can environmental factors affect inheritance? (Use human height as an example.)
Answer:
See below
Explanation:
There were yellow seedlings in Dish #1 during the light phase and also during the dark in Dish #2. The difference in these results is likely due to the period of exposure to light.
There are more number of yellow seedlings on Day 4. This is probably because of being kept in the dark for a long period of time. Light intensity is the experimental variable that accounts for this difference in appearance.
The yellow color is being environmentally controlled since the parent phenotype was wildtype in this experiment. The environment has an effect on which genes are expressed in the organism, which in turn influences the phenotype observed.
A single point mutation in a gene results in a nonfunctional protein. Individuals heterozygous for this mutation were identified using a Southern blot. Which pair of wild-type (WT) and mutant alleles most likely contains the mutation?
A. WT 5-TAGTCGAAGCTTAGGCATCT-3
Mutant 5-TAGTCGATGCTTAGGCATCT-3
B. WT 5-TAGTCGAAGCTTAGGCATCT-3
Mutant 5-TAGTCGAAGCTTAGGCATAT-3
C. WT 5-TAGTCGAAGCTTAGGCATCT-3
Mutant 5-TAGTTGAAGCTTAGGCATCT-3
D. WT 5-TAGTCGAAGCTTAGGCATCT-3
Mutant 5-TAGTCCAAGCTTAGGCATCT-3
Answer:
C. WT 5-TAGTCGAAGCTTAGGCATCT-3
Mutant 5-TAGTTGAAGCTTAGGCATCT-3
Explanation:
In the wild type, the DNA sequence encodes the following aminoacidic segment: SRSLGI; while the mutant form has a stop codon in the second codon (TGA). A stop codon is a trinucleotide sequence in the messenger RNA (mRNA) that indicates a stop signal in protein synthesis. There are three types of stop codons: UGA, UAG and UAA, where U represents Uracile in the mRNA instead of Thymine in the DNA sequence.
Representation:
C. WT 5-T AGT CGA AGC TTA GGC ATC T-3 >> 5'3' Frame 1 = SRSLGI
Mutant 5-T AGT TGA AGC TTA GGC ATC T-3 >> 5'3' Frame 1 = S-, where - represents a stop codon (TGA) and therefore it is the end of the protein.
Each of two parents has the genotype brown divided by red, which consists of the pair of alleles that determine hair color, and each parent contributes one of those alleles to a child. Assume that if the child has at least one brown allele, that color will dominate and the child's hair color will be brown. a. List the different possible outcomes. Assume that these outcomes are equally likely. b. What is the probability that a child of these parents will have the red divided by red genotype? c. What is the probability that the child will have brown hair color?
Answer:
Explanation:
From the given information:
Each of two parents has the genotype brown divided by red
So ;
The man's genotype is : [tex]\mathbf {\dfrac{Brown}{Red}}[/tex]
The woman's genotype is : [tex]\mathbf {\dfrac{Brown}{Red}}[/tex]
This [tex]\mathbf {\dfrac{Brown}{Red}}[/tex] genotype consist of the pair of alleles that determine hair color
Now; we are given an assumption that:
if the child has at least one brown allele, that color will dominate and the child's hair color will be brown.
i.e Brown allele is dominant to Red allele
(a) List the different possible outcomes.
The cross between :
[tex]\mathbf {\dfrac{Brown}{Red}* \mathbf {\dfrac{Brown}{Red}}}[/tex] will produce the following offsprings which is the different possible outcomes.
[tex]= \mathbf {\dfrac{Brown}{Brown} \ \ : \ \ \mathbf {\dfrac{Brown}{Red}} \ \ : \ \ \mathbf {\dfrac{Red}{Brown}} \ \ : \ \ \mathbf {\dfrac{Red}{Red} }}[/tex]
(b) . What is the probability that a child of these parents will have the red divided by red genotype?
The probability that the child of these parents will have [tex]\mathbf {\dfrac{Red}{Red} }}[/tex] is one out of four
i.e
= 1/4
= 0.25
(c) What is the probability that the child will have brown hair color.
We are being told that; if the child has at least one brown allele, that color will dominate and the child's hair color will be brown.
i.e Brown allele is dominant to Red allele
Thus; from above we will see that three of the offsprings have at least one brown allele;
Thus; the probability that the child will have brown hair color is = 3/4
= 0.75
