Please describe the regulation of the blood glucose 6 hours after a meal?
Please include all relevant organs, hormones, and actions.
Answer:
Find the description below in the explanation section
Explanation:
The body system regulates the blood sugar level via the hand-in-hand working of insulin and glucagon hormones, both produced by the Pancreas. After a meal, the food undergoes digestion and is broken down into glucose, which is absorbed into the bloodstream. Insulin hormone is released by the pancreas (stimulated by a negative feedback) when the sugar level of the blood increases. This secretion of insulin causes cells to absorb glucose as source of energy, while liver and muscle cells store some of the excess blood glucose as GLYCOGEN.
However, after about 6 hours of taking the meal, the blood sugar (glucose) level must have decreased. This triggers the secretion of Glucagon hormone by the Pancreas. Glucagon hormone, acts in an opposite manner as Insulin hormone, by causing the stored GLYCOGEN in the liver and muscle cells to be converted back to Glucose in order for cells to make use of it.
This continuous process occurs and it is how the body regulates the blood glucose levels.

Macromolecules in the cell can often interact transiently as a result of noncovalent interactions. These weak interactions also produce stable, highly specific interactions between molecules. Which of the factors below is the most significant in determining whether the interaction will be transient or stable?
a) the size of each molecule
b) the number of chemical bonds between the molecules
c) the concentration of each molecule
d) rate of synthesis
Answer:
The correct answer is option b) "the number of chemical bonds between the molecules".
Explanation:
Chemical bonds are the forces that enable the formation of compounds. The number of chemical bonds is a determining factor to know if an interaction will be transient of stable. The more chemical bonds the more stable an interaction will be. Few chemical bonds between molecules makes an interaction unstable and easy to break, enabling transient interactions that are key to certain biological pathways.
What do eukaryotic cells have that prokaryotic cells do not?
In 1668 Francesco Redi did a series of experiments on spontaneous generation. He began by putting similar pieces of meat into eight identical jars. Four jars were left open to the air, and four were sealed. He then did the same experiment with one variation: instead of sealing four of the jars completely, he covered them with gauze (the gauze will exclude the flies while allowing the meat to be exposed to air). In both experiments, he monitored the jars and recorded whether or not maggots (young flies) appeared in the meat.
Refer to the paragraph on Redi's experiments. In both experiments, fies appeared in all of the open jars and only in the open jars. Which one of the following statements is correct?
A. The experiment was inconclusive because it did not nun long enough
B. The experiment supports the hypothesis that spontaneous generation occurs in rotting meat.
C. The expertment supports the hwpothesis that maggots arise only from eggs laid by adult flhes
D. The experiment was inconclusive because Redi used only one kind of meat
Answer:
The experiment supports the hypothesis that maggots arise only from eggs laid by adult flies; that is only from reproduction and development.
Explanation:
The objective of this experimental set up by Francesco Radi was to demonstrate the concept of spontaneous generation. He concluded that, Maggots are not spontaneous generated from rotten meats, rather they are products of eggs laid by houseflies who visited the rotten meat to lay eggs. The maggots (larva) are products of complete metamorphosis, from egg to larva to pupa and adult. This is an indication that, new organisms are not formed form spontaneously, but are products of well-defined process of reproduction and development which in this case is a complete metamorphosis.
Based on this premise he concluded that, if maggots were products of laid eggs, then they should appear only when rotten meat is exposed to open air.However,if they are f products of spontaneous generation they should appear irrespective of the meat exposure to air or not.

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

If the Hemoccult test result is negative, no further testing is done. If the Hemoccult test result is positive, the individual will have a second stool sample tested with the Hemoccult II test. If this second sample also tests positive for blood, the individual will be referred for more extensive evaluation. What is the effect on net sensitivity and net specificity of this method of screening
Answer:
Hemoccult test sensitivity is 89.3% and specificity is 92.7%
Explanation:
Hemoccult test is a test that is carried out in order to find out the presence of occult blood in your stool. This method is used to detect colorectal cancer in your body. Blue color of the blood indicate that the test is positive while the green color represents that the test is negative. Test sensitivity is the ability of a test which identify the person who is affected with the disease i. e. true positive, whereas test specificity is the ability of the test to correctly identify the patient without the disease. The value of sensitivity of the Hemoccult test is 89.3% the specificity is 92.7%, and the positive predictive value is 2.5%.
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.
A possible explanation for the differences in structure, function, and behavior between
chimpanzees' and humans is provided by the
bota
Answer:
The theory of evolution by natural selection
Explanation:
Nowadays, it is widely accepted that chimpanzees are primates closest related to us. Darwin's postulated "The theory of evolution by natural selection", in the book "On the Origin of Species" in 1859. It is a theory that explains how species evolve over successive generations by gradual changes and the selection of the most adaptive phenotypes. Anatomical, fossil, and genetic evidence support the idea of an evolutionary link as Darwin predicted between hominids (humans) and other primates.
In regard to genetic evidence, whole-genome sequence analyses have shown that humans and chimpanzees share about 98% of sequence homology. Moreover, according to the phylogenetic tree, both species evolved from one common ancestor that was present approximately 4 million years ago.
In regard to anatomical and fossil evidence, it has been discovered that the chimp brain has a similar size to human extinct relatives, and thereby also supporting an evolutionary link between both species.
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?

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.

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.

Measure the somatic mutation rates for the putative DNA repair mutant plants.
Measure the germline spontaneous and induced mutation rates for the putative DNA repair mutant plants.
Expose putative DNA repair mutant plants to ionizing radiation L and see if they survive less well than wild-type plants. This will allow the breeder to see and analyze the ability of DNA repair in tomatoes
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.
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.

As an upcoming microbiologist state the keeping steps you would to stain the smear using Gram stain.upon examination, you've found blue coloured graped-cluster berry round the cell
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.

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.
