Explanation:
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,
If an isolated population’s birthrate is the same year after year, why are a greater number of individuals added to the population in each successive year?
A) The effective birthrate is increasing each year.
B) The carrying capacity is increasing each year.
C) The rate applies to more individuals each year.
D) Fewer members emigrate away each year.
Answer:
C) The rate applies to more individuals each year.
Explanation:
Suppose the initial population was 200 people and birth rate was 10% of that. So thats 0.10 * 200= 20 babies that year.
Next year the population is 200+ 20 = 220 people. Now if the birth rate is still 10% then you will have 0.10 * 220 = 22 babies that year.
Did you see that? The number of babies increased by 22-20= 2 extra babies each year.
Therefore, since rate applies to more individuals each year, you'll get increase in population
45-year-old was admitted with sarcoidosis of both lungs. An extracorporeal perfusion of donor lungs, from an unrelated donor, and successful bilateral lung transplantation were completed without any complications. What is the second code you should assign
Answer:
The second code in this case is the procedure for perfusion
Explanation:
Extracorporeal perfusion is the process of diverting the patient's blood via an artificial circulatory device to enable the gas exchange (oxygen absorbed, carbon dioxide removed) to take place. Only medical experts should handle this procedure so as to avoid any and all undesired scenarios or negligence towards patient care.
Which is a function of nucleic acids? create movement provide structure store genetic information fight disease
Answer:
store genetic information
Storage of genetic information is the main function of nucleic acids. As the nucleic acid contains genes that codes for certain characters of the humans that are being inherited from parents to offspring. The correct option is C.
What are nucleic acids?Nucleic acids are chemical compounds that arise innately and are the primary information-carrying substances in cells.
They are extremely significant in guiding protein synthesis. Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are indeed the two primary kinds of nucleic acids.
There are many organisms that contains RNA as a genetic material, and some have DNA as genetic material.
Nucleic acids play an important role in the stockpiling and expression of genomic information. DNA, or deoxyribonucleic acid, encodes the information that cells require to produce proteins.
Thus, the correct option is C.

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.

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.

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.

Consider a gene with three alleles controlling coloration of a flowering plant. There are 3 possible phenotypes, corresponding to the following dominance hierarchy among the alleles: A1 is dominant to A2 and A3, and A2 is dominant to A3. Which of the following genotype pairs express the same phenotype?
A.
A2A2, A3A3
B.
A1A1, A3A3
C.
A1A2, A1A3
D.
A2A3, A1A3
Answer:
C. A1A2, A1A3
Explanation:
This question depicts a gene coding for coloration in a flowering plant. The gene is controlled by multiple alleles, three specifically. The alleles are labelled A1, A2, and A3, with each coding for it's own respective trait.
According to the question, A1 is dominant over A2 and A3 i.e. A1 will always mask the phenotypic expression of A2 and A3 and express itself. Also, A2 is dominant over A3 i.e. A2 will always mask the phenotypic expression of A3. This overall means that the trait encoded by allele A3 will only be expressed when the same alleles are present.
To the question; since A1 is dominant over the other two alleles (A2 and A3), it will be phenotypically expressed ahead of them in a heterozygous state with both alleles. That is, A1A2 genotype will give rise to a phenotype encoded by A1. Also, A1A3 will produce a phenotype encoded by A1. Hence, genotypes A1A2 and A1A3 will express the same phenotypes.
A2A2 and A3A3 will express different phenotypes since they are both in a same alleles condition. Likewise for A1A1 and A3A3. A2A3 and A1A3 genotypes will express different phenotypes encoded by A2 and A1 respectively since they are both dominant over A3.
The speckled chicken on the right results from a cross between a black and white chicken. Explain what type of inheritance this would be, and draw a punnett square to show how this would happen.
Answer:
- Codominance
- 100% speckled chicken
Explanation:
This gene inheritance is called codominance, where both alleles can be expressed. In these cases, heterozygote individuals instead of showing an intermediate phenotype, express both alleles. Their phenotype is an additive expression of their parents' genes.
When two individuals, homozygous for a certain trait, are crossed they produce heterozygous individuals that express both alleles equally.
A typical example of codominance is the case of speckled chicken, the product of the cross of a black individual with a white individual. Black chickens (BB) only have this gene for feather color, while white chickens (WW) only have the gene for white feathers. When they cross, their progeny will have both genes (BW), and both of them will be expressed as speckled feathers.
Cross:
Parental) BB x WW

Gametes) B B W W
Punnet square) B B

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.

Explanation:
In an accident with farm machinery, Mr. Roque had his left arm severed just below the elbow. Mrs. Roque stopped the bleeding, called for an ambulance, and packed the severed arm in ice for the EMTs to take to the hospital. Will Mr. Roque ever be able to move the fingers of his left hand again? What structures must be reattached, and what has to happen?
Answer:
The mentioned case of arm severing is considered as major surgery, and the restructuring of the severed arm is only possible when Mr. Roque will reach the hospital within four to five hours of the incident, also known as the window period.
After performing the surgery, Mr. Roque may regain movement in the arm to some extent after performing certain kinds of exercises, however, he may not feel the sensations in the fingers of his left hand again. The entire process of healing of the severity may take about two to three years, and in certain cases, the body fails to heal completely, and the affected limb may lose its function entirely.
In the given case, the structures that are required to get reattached are the muscles of the forearm and the blood vessels and the nerve supply to the affected region. The systematic arrangement of these structures is done with the help of surgery. However, after the surgery, the patient is recommended to perform certain kinds of hand and finger muscle exercises so that the functioning of the arm get regain slowly and gradually.

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%.

What evidence provided supports the claim that "a high level of testosterone provides an unfair advantage in women’s athletics? is this adequate evidence? explain your answer.
Answer:
Although higher levels of testosterone in women cause an increase in muscle mass, this condition is also associated with health problems including, among others, infertility, polycystic ovarian syndrome, hirsutism, sleep apnea, irregular menstrual cycles and obesity, and therefore affecting their athletic performance.
Explanation:
A high level of testosterone in females not only influences their physical appearance, and its imbalance has been associated to health issues that affect women's athletic achievement. Testosterone is a hormone that controls gene expression in multiple organs and one of the most important metabolic regulators of sugar, lipids and proteins, thereby level higher than normal may cause the loss of the organism's homeostasis in women.

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

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.
