Answer:
C) An extra chromosome is added, causing mismatching of the chromosome pairs.
Explanation:
Mutation is any change, whether big or small, that occurs in the nucleotide sequence of a gene. Mutation can be of different types depending on how it occurs.
According to the question, frameshift mutation is a mutation that causes the normal reading frame of the nucleotide sequence to be altered. It is caused when an extra chromosome is added (insertion) or when one chromosome is removed (deletion). In either way, there will be a mismatch or alteration in the chromosome pair, hence affecting the reading of the nucleotide sequence.
In frameshift mutation, the insertion or deletion causes the
normal CODONS (triplet nucleotide) to be missing or incomplete, hence, disrupts the manner at which the reading takes place (reading frame). Note, frameshift mutation only occurs as a result of insertion or deletion of chromosomes/bases that are not multiples of three that can maintain the normal reading pattern/frame.
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
The next morning your team returns to work in the laboratory, where you get a call from the sheriff. The family of the three missing boys is pressuring him for information. Your team begins the final osteological exam. After careful examination, you produce your final inventory. You are working with the same number of bones, but you now have determined which side of the body they come from (when applicable).
You have:_______.
• 3 skulls
• 6 femora (4 right and 2 left)
• 4 os coxae (All adolescent males, 1 right and 3 left)
• 2 humeri (both right)
• 2 tibiae (both left)
• 5 scapulae (3 right and 2 left)
1. Based on the revised inventory, would you change your MNI? If so, what would be the new MNI?
2. What do you tell the sheriff? Are these the missing boys?
Answer:
See below
Explanation:
1. Yes, the MNI ought to be changed in light of the revised inventory. Since 4 of the 6 femora are right sided, they would belong to different individuals, so the MNI would now be stated as 4.
2. The sheriff would be told that the possibility of suspecting 22 individuals is very narrow, though not impossible. It is also unlikely that the victims are numbered less than 4 in accordance to the bones found.

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 of the following statements is NOT true? The three types of lipid anchors responsible for tethering proteins to the bilayer are acylation, prenylation, and GTPase anchors. Glycoproteins are always oriented so that the carbohydrate moieties are exoplasmic. Glycoproteins are the basis for blood type compatibility between donor and receiver. Movement of proteins from the cytoplasmic to the exoplasmic face of the lipid bilayer requires specialized transport proteins, often flippases.

In your own words, explain why the geological structures in Florida are less complex than the geological structures in Colorado.
Answer:
Different parts and regions have distinct features and characteristics.
Colorado is known to have lots of mountains. Florida is however a humid-subtropical region. This makes differences in the types of loving organisms found in the named region. There are also different ages in geological structures.
Colorado has lots of rocks in the region and is as result of the presence of rigid hills and mountains while Florida is more tropical and has a coastal processing climate with low prevalence of rocks.
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.

Explanation:
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%.
A woman with type A blood (whose father was type O) has children with a man that has type O blood. Both individuals are heterozygous for the MN antigen. Recall that MN blood group antigens are independent of the ABO locus, and that the alleles are codominant.
How would the results from Part A change if both parents are also heterozygous for the FUT1 gene controlling the synthesis of the H substance (Hh)?
Drag the correct value to the blank following each offspring type.
Type A with M antigen:_________.
Type A with M and N antigens:_________.
Type A with N antigen:__________.
Type O with M antigen:__________.
Type O with M and N antigens:__________.
Type O with antigen:_________.
Options: 0, 1/32, 3/32, 5/32, 6/32, 10/32, 1
Answer:
Explanation:
A woman with type A blood (whose father was type O) meaning her genotype is AO mates with
Man that has type O blood (OO genotype)
Both are heterozygous for MN blood group and both also heterozygous for the FUT1 gene controlling the synthesis of the H substance (Hh)- which determines the expression of the A and B antigen.
Cross
A O M N H h
O AO OO M MM MN H HH Hh
O AO OO N MN NN h Hh hh
Type A- 1/2 O-1/2 type M- 1/4 MN-1/2 N- 1/4, type H- 3/4 h-1/4
Type A with M antigen:
1/2*1/4*3/4 = 3/32
Type A with M and N antigens:
1/2*1/2*3/4 = 3/16
Type A with N antigen:
1/2*1/4*3/4 = 3/32
Type O with M antigen:
1/2*1/4*3/4= 3/32
Type O with M and N antigens:
1/2*1/2*3/4 = 3/16
Type O with N antigen:
1/2*1/4*3/4 = 3/32.
The 3/4 value comes from the expression of Hh-3/4 (this determines if the A and B Angie will be expressed).
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.
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.

Explanation:
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.
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 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.
