Answer:
They can be found in several trophic levels, as they are related with several trophic level, hence, they cannot be placed on a specific trophic level.
Explanation:
A trophic level is a specific position occupied by a group of organisms on a good chain in relation to their nutrition.
Dentrivores feed on the waste of other organisms and cannot be really placed on a specific trophic level, likewise decomposers, of which they feed and decompose the body of organisms.
Omnivores feed on both plants and animals, which includes producers and consumers. Placing omnivores on a specific trophic level would not be really straightforward also.

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.

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.

Hello. You forgot to put the image so that this question can be answered, but I will describe what the image shows.
The image shows two types of "cups" that have a type of connection between the two. In cup A there is 1 mole of glucose and 1 mole of fructose. In cup B there is 0.1 mol of glucose and 1.5 mol of fructose.
Answer:
A. Solution A to Solution B
Explanation:
Balance is achieved when the "cup" with the lowest concentration of glucose receives glucose from the "cup" with the highest concentration, to the point that the two glasses establish equal concentrations of glucose between them.
We know that cup B has a lower concentration of glucose, which indicates that the movement of this solute was from cup A towards cup B. With this we can conclude that the letter A is the correct answer.
In garden peas, the allele for tall plants (T) is dominant over the allele for dwarf plants (t).

infIdentify flexor digitorum profundus in the right upper limb and the ulnar vein that is immediately superficial to it on its medial surface. What is the correct order of veins that blood flows through to reach the heart from the right flexor digitorum profundus and the right ulnar vein
Answer:
The upper region of the body veins carries blood that has no oxygen to the heart through superior vena cava and the lower part of the blood with no oxygen will transfer to the heart with the help of superior vena cava.
In Right hand:
At first, blood in the palmar region or distal end of the arm deoxygenated blood from this side will go to the following manner -
right ulnar vein - to the right Axillary vein - to the right subclavian vein - Right internal jugular vein - right brachiocephalic vein and finally it reaches the superior vena cava of the heart.
The same pathway will take place on the left side of the upper region of the body.

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
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.

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.
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.

Each trait of a plant is determined by _____.
A) an allele
B) one gene
C) a pair of genes
D) one dominant gene
Answer:
c. a pair of genes
Explanation:
Answer:
C) a pair of genes
Explanation:
C should be correct because each trait is controlled my multiple genes. It is very rare to see one thing being controlled strictly by one gene, rather multiple things work together to produce the traits. Living things are very amazing if you dive deep into their DNA level,
Many types of cancer are known to overexpress the receptor protein tyrosine kinase. Which molecular technique can be used to reduce expression of tyrosine kinase in cell culture?
Answer:
By phosphorylation or by activating cyclin-dependent kinase-mediated signaling pathways
Explanation:
The Cyclin-Dependent Kinases (Cdks) are a family of critical regulatory proteins capable of modulating the progression through the cell cycle. Cdks are in turn regulated by binding to cyclin proteins or by phosphorylation at specific amino acid residues (generally tyrosine and threonine).
Phosphorylation is the most widely studied posttranslational modification and it is known to inhibit (and also activate) protein function, while cyclin-dependent kinases are proteins known to inhibit the activity of Cdks and thereby acting as tumor suppressors by inducing cell death-apoptosis.
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.
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%.
