Scenario 2:

Mike was adopted, and his biological family history is unknown. Although he is healthy, he would like some understanding of his genetic makeup, including potential health risks and genes that he could pass on to his children. Mike has heard about commercial laboratories that can compare segments of your DNA to those of people with common hereditary diseases in order to give you some idea of how susceptible you are to the diseases. The results of these types of tests are highly inconclusive. If Mike’s DNA showed that he shares similarities in a segment of DNA with people who have a given disease, his chances of developing that disease or passing it on to his children may be slightly elevated, but they are not 100 percent. These tests can cost more than $2,500 and are not covered by many insurance companies.

For each of the following structures, first indicate its function in the fetus; then, note its fate (what happens to it or what it is converted to after birth).

a. Umbilical artery
b. Umbilical vein
c. Ductus venosus
d. Ductus arterious
e. Foramen ovale

Answers

Answer:

1. Functions:

a. Umbilical artery >> carries deoxygenated blood from the fetus to the placenta

b. Umbilical vein >> transports oxygenated blood from the placenta to the fetus

c. Ductus venosus >> allows oxygenated blood from the placenta to bypass the liver

d. Ductus arterious >> allows most of the blood from the right ventricle to bypass the fetus's non-functioning lungs

e. Foramen ovale >> oxygenated blood from the umbilical vein to bypass the pulmonary circulation

2. After the bird:

1. Umbilical artery >> medial umbilical ligament

2. Umbilical vein >> round ligament of the liver

3. Ductus venosus  >> ligamentum venosum

4. Ductus arteriosus >> ligamentum arteriosum

5. Foramen ovale >> fossa ovalis

Explanation:

The umbilical artery is a paired artery localized in the abdominal and pelvic regions, which carries deoxygenated blood from the fetus to the placenta through the umbilical cord. The medial umbilical ligament is the obliterated part of the umbilical artery that arises from the internal iliac arteries. In utero, the umbilical arteries carry waste products back to the placenta, whereas the umbilical vein carries oxygenated blood from the placenta to the fetus. The round ligament of the liver (also known as ligamentum teres hepatis) is a remnant of the umbilical vein that  exists in the embryonic stage, it connects the left lobe of the liver to the umbilicus. The ductus venosus is a slender shunt that allows oxygenated blood from the placenta to bypass the liver, it connects the intra-hepatic portion of the umbilical vein to the inferior vena cava. The ligamentum venosum is an extrahepatic, slender, and fibrous remnant of the fetal ductus venosus that travels between the left portal vein and the inferior vena cava. The ductus arteriosus is a fetal artery that connects the aorta to the pulmonary artery. The ligamentum arteriosum is a nonfunctional vestige of the ductus arteriosus, it is attached to the superior surface of the pulmonary trunk. The foramen ovale is an oval-shaped, small, opening in the wall (septum) between the two upper chambers of the heart. The fossa ovalis is a vestige stricture of the foramen ovale of the embryonic heart, which forms a depression in the right atrium of the heart.

A) 1 black-eyed:1 orange-eyed
B) 3 black-eyed:1 orange-eyed
C) 1 black-eyed:3 orange-eyed
D) 1 black-eyed:0 orange-eyed

Answers

The phenotypic ratio of the cross is as follows: 3 red antennas: 1 white antenna

For question 2, the phenotypic ratio of the F2 generation is: 3 black-eyed: 1 orange-eyed

QUESTION 1

According to the first question, a gene coding for antenna color in butterflies is involved. Red antennas (“R”) is dominant to white antennas (“r”). Hence, a butterfly with genotype "Rr" will be phenotypically red.

According to this question, If both parents are heterozygous for red antennas i.e. Rr (red antenna) × Rr (red antenna), the following gametes will be produced: R and r. Using these gametes in a punnet square (see attached image), the following phenotypic ratio of offspring is produced:

3 RED ANTENNAS (RR, Rr, Rr) : 1 WHITE ANTENNA (rr)

2. In the second question, all the offspring of a cross between a black-eyed mendelien (BB) and an orange-eyed mendelien (bb) have black eyes (Bb). In a cross between two F1 black-eyed mendeliens i.e. Bb × Bb, the following proportion of offspring is produced:

BB, Bb, Bb, bb

Hence, a phenotypic ratio of 3 black-eyed: 1 orange-eyed

You have a microorganism you know is both fastidious and which normally lives in human lungs. Which medium might this organism have the highest probability of growing on and why

Answers

Answer:

It is likely that this microorganism grows in enriched culture media.

Explanation:

As shown in the question above, the microorganism that lives in the lungs is extremely demanding. This means that this microorganism is very difficult to be cultivated in a culture medium, as it requires specific nutrients and in specific amounts to be able to develop. These microorganisms are called fastidious microorganisms and need an enriched culture medium to develop.

Enriched culture media are those that have a high range of nutrients in their composition. These culture media are highly nutritious and for this reason, they are the ideal environment for demanding microorganisms, as it can efficiently meet the needs of this organism.

explain how the mammalian skin perform it's role as a thermoregulatory



Answers

Answer:

The skin contains many blood capillaries and sweat glands ,the sweat glands secrete sweat when it is hot.when the sweat evaporates from the skin it cools the body.thermoregulation by the skin occurs through dilation and constriction of the blood vessels.when the bodies temperature raises,the blood vessels carry heat in the blood to the skin.the blood capillaries dilate become wider so that more heat can be lost to the environment.this is called vasodilation.when the outside temperature is low,the blood capillaries constrict become narrower so that less blood flows to the surface of the skin.therefore less heat is lost to the environment this is called vasoconstriction.

Given the range of current speeds shown on the graph above, would deposition ever be possible for clay (0.001 mm) or silt (0.01mm) particles?
Answer yes or no and explain your answer.

Answers

Answer:

Yes.

Explanation:

Yes, deposition can be possible for clay (0.001 mm) and silt (0.01mm) particles when the agent that carry its load is absent in that region such as wind. Wind is the agent that moves clay and silt particles with it so if there is high wind in a specific region, no deposition will occur while on the other hand, those areas where wind is not present, deposition will definitely occurs so we can say that deposition depends on the presence and absence of wind.

Thymine in DNA occurs as the result of thymidylate synthase creating _______________ , which then undergoes ____________ to ____________, then to __________, and incorporated into DNA by ___________.

Answers

Answer:

The question is incomplete, the complete question is as follow:

Thymine in DNA occurs as the result of thymidylate synthase creating _______, which then undergoes _______ to _______, then to _______, and incorporated into D N A by _______. Thymine in tRNA arises ________, by an S-adenosylmethionine-dependent _______ of a ______ residue in RNA.

Answer:

Thymine in DNA occurs as the result of thymidylate synthase creating dTMP, which then undergoes phosphorylation to dTDP, then to dTTP, and incorporated into DNA by DNA polymerase. Thymine in tRNA arises posttranslationally, by an S-adenosylmethionine-dependent methylation of a UMP residue in RNA.

Explanation:

Thymidylate synthase is a key enzyme that catalyzes the synthesis of 2′-deoxythymidine-5′-monophosphate (dTMP) from 2′-deoxyuridine-5′-monophosphate (dUMP). This enzyme catalyzes the addition of a phosphate group (phosphorylation) of dTMP in order to form thymidine 5'-diphosphate (dTDP). Once synthesized, dTMP can be metabolized to deoxythymidine triphosphate (dTTP), which is a precursor for DNA biosynthesis. On the other hand, transfer ribonucleic acid (tRNA) is methylated after the molecule is synthesized. The transfer of the methyl group is catalyzed by an S-adenosylmethionine–dependent methyltransferase that catalyzes the methylation of uridine monophosphate (UMP) using SAM (S-adenosylmethionine) as the methyl donor.

What is a major role that fungi play in ecosystems

Answers

Answer:

Fungi play a crucial role in the balance of ecosystems. They colonize most habitats on earth, preferring dark, moist conditions. They can thrive in seemingly-hostile environments, such as the tundra. However, most members of the Kingdom Fungi grow on the forest floor where the dark and damp environment is rich in decaying debris from plants and animals. In these environments, fungi play a major role as decomposers and recyclers, making it possible for members of the other kingdoms to be supplied with nutrients and to live.

Answers

The answer is c but this has to be twenty characters long

The accuracy of a confidence interval calculation can be increased from  95% to 99%.

Thus, option C is correct.

What is confidence interval?

A confidence interval contain a population parameter in a specified proportion of the time, which can be computed using the given confidence level from a limitless level of individual sample.

The proportion of the range consists of the true value of the factor that will be identical to the confidence level.

In most of the confidence interval examples, the confidence level chosen is 95%. and it can be raise up to 99%.

It cannot estimate the plausible values of the unknown parameter of the population.

Two types of confidence interval observed such as accuracy which is defined based on whether the confidence interval contains the true population parameter or not.

Secondly, the precision defined in terms of the width of a confidence interval.

Answers

NB: This is a business question, not biology.

Answer:

SAC (Short-run Average Cost) and LAC (Long-run Average Cost)

The stronger argument regarding the SAC (Short-run Average Cost) curves and the LAC (Long-run Average Cost) curves is:

A. The draftsman since the lowest point on each SAC curve will have a horizontal tangent line which only occurs at the lowest point on the LAC.

Explanation:

The costs of all factors of production become variable in the long run.  But in the short-run, some costs are variable, and some are fixed.  When the producer starts operating over the long run period, it can then operate without the constraints imposed by the presence of the fixed-cost factors. Therefore, in the long run, the average cost (LAC) is equal to the short-run average cost (SAC) because there is an unconstrained minimum average cost at all output levels.
