Use Figure 1 Tay-Sachs Disease Pedigree to answer the following questions.
a.Interpret what the Roman numerals in the pedigree diagram represent.
b.Interpret the genotypes of the parents in this diagram.
c.If a person who does not carry the Tay-Sachs disease gene marries offspring II4, what are the possible genotypes for their children?
Answers
Answer:
Please see the answer below
Explanation:
a. The roman numerals represent the various generations in the pedigree.
I represents first generation
II represents the second generation
b. The half shaded square and circle representing the parents means that both of them are carriers for the trait in question. Tay-Sachs disease is an autosomal recessive inheritance, assuming the trait is represented by the allele a, the gentoypes of the parents would be Aa and Aa respectively.
c. Still on the assumption that the disease is represented by the allele a. If offpsring II4 which happens to be free of the Tay-Sachs allele marries a person that also does not carry the Tay-Sachs disease gene, the cross will be as shown below.
AA x AA = AA, AA, AA, and AA.
All the children would be free from the Tay-Sach's allele. That is, they will be homozygous normal.
The roman numerals in the pedigree diagram represent are :
I = represents first generation
II = represents the second generation
Part B:The genotypes of the parents would be Aa and Aa .
Half-shadowed squares and circles that represent the parent mean that both are carriers of the characteristics of the problem. TaySachs disease is autosomal recessive when the trait is represented by the allele a.Part C:The possible genotypes for their children are:AA x AA = AA, AA, AA, and AA.
All the children would be free from the Tay-Sach's allele.Find more information :

If the interference value is 1, then what is the probability of recombination between genes A and B if: 1.There is a recombination between genes B and C, where the gene order is A-B-C; 2.The recombination fraction between A and B is 0.05; 3.The recombination fraction between B and C is 0.45?
A. 0.45.
B. 0.05.
C. 1.00.
D. 0.15.
E. 0.0.
Answers
Answer:
E. 0.0.
Explanation:
The measure of crossing over coincidence interrelatedness between one cross over and another in a given pair of chromosome is known as what is called Interference.
Given that :
the interference value = 1
The probability of recombination between genes A and B is zero i.e 0.0 because:
when another gene co-occur with a particular gene during cross over, the coefficient of coincidence decreases. We know that the interference is maximum at 1, we can say it ranges from 0-1; now that two recombination is taking place in two genes,the probability is likely to decrease from 1 to 0.0
Similarly; Since the probability of recombination is taking place between two genes i.e genes A and B. Then there is no probability of double crossover when interference value = 1 but when it is zero there is probability of double crossover to occur. With that being said, the probability of recombination between genes A and B is 0.0

Which of the following is NOT a reason bacteria are good for genetic engineering? A. Their DNA accepts new genes more easily than Eukaryotes. B. DNA is easy to access and modify. C. They replicate very quickly. D. Plasmids can be engineered easily to produce proteins.
Answers
Answer:
D
Explanation:
"Scientists insert genes into loops of DNA called plasmids using natural processes and technological innovations. They can then introduce plasmids into bacteria or other cells, which replicate the inserted genes or induce the cells to produce such valuable proteins as human insulin and growth hormone."
The following is not a valid reason that indicates bacteria are good for genetic engineering:
Plasmids can be engineered easily to produce proteins.Thus, the correct option is D.
What is Genetic engineering?Genetic engineering may be defined as a methodology that utilizes laboratory-based technologies and equipment that support in the alteration of the DNA makeup of an organism.
A plasmid is a genetic structure that mediates the translocation of the genetic material of one organism to another for the purpose of modification.
Examples include insulin production, hormone synthesis, increase productivity in plants, etc.
The Plasmid is inserted into bacterial cells when the genetic material of the experimental organism is successfully employed. This process does not deal with the reason that bacteria are good for genetic engineering.
Therefore, the correct option is D.

If the surface soil is saturated and precipitation increases, there will be
a. a decrease in the surface elevation of the lake
b. a decrease in the amount of groundwater
c. an increase in the rate of capillarity
d. an increase in the amount of runoff
Answers
The correct answer is D. An increase in the amount of runoff
Explanation:
Surface soil is considered to be "saturated" if soil cannot absorb more water as all pores in it are already filled. This can occur when there has been a lot of precipitation, or the retention of soil is low. Additionally, when soil is saturated and it is in contact with more water (for example, if precipitation increases) the water will not be absorbed by the soil but will flow to other areas, which is known as runoff. Thus, if the surface soil is saturated and there is precipitation, there will be an increase in the amount of runoff.

Develop a hypothesis to explain why you think eurypterids developed legs even though they lived on the ocean floor.
Answers
I think that since it lives on the ocean floor, at the deepest of the ocean. So anyway, the fin on the Eurypterids is still necessary but not that much, since they live on the ocean floor. Their movements mostly on the ocean floor. So fin would not help them "stick" to the floor. Also there are still gravity acts on the Eurypterids and the feet would help them move faster.

Name the ionic compound PbCO3
Answers
Answer:
lead carbonate
Explanation:
The ionic compound PbCO3 is called lead(II) carbonate.
Let's break down the name to understand it better:
1. The symbol "Pb" represents the element lead.
2. "CO3" is the chemical formula for carbonate, which is a polyatomic ion consisting of one carbon atom and three oxygen atoms.
To name the compound, we use the Stock system for naming compounds containing transition metals like lead.
1. The Roman numeral "(II)" indicates the charge of the lead ion in the compound. In this case, lead has a +2 charge. The Roman numeral helps differentiate between different possible charges of the metal ion.
2. The word "carbonate" represents the polyatomic ion CO3.
Therefore, the name of the ionic compound PbCO3 is lead(II) carbonate.

What types of enzymes play a catalytic role in the regulation pathway of ubiquitination?
Answers
Answer:
ubiquitin activating enzyme ( E1), a ubiquitin conjugating enzyme (E2), and a ubiquitin ligase (E3).
Explanation:
In ubiquitination, ubiquitin (regulatory protein) attach to a protein to inactivate it and targets a protein for degradation via the proteasome.
There are three enzymes sequentially catalyse the process of ubiquitination that includes ubiquitin activating enzyme ( E1), a ubiquitin conjugating enzyme (E2), and a ubiquitin ligase (E3).
The E1 activates ubiquitin by forming a thiol ester bond between the C terminus of ubiquitin and the active cysteine of the E1 which is an ATP dependent step.
The activated ubiquitin then tranferred to cysteine of E2 which along with E3 transfers the ubiquitin to a lysine residue in the target protein.
Hence, all three ubiquitin activating enzyme ( E1), a ubiquitin conjugating enzyme (E2), and a ubiquitin ligase (E3) enzymes sequentially catalyse the process of ubiquitination.

What is the potential problem for robotic rovers on Mars?
Answers
Answer:
The limited autonomy of the robotic rovers on Mars posed a big problem.
Explanation:
Missions are very costly, and can lead the project to fail with the simplest errors. If the rover was permanently trapped on a rock or destroyed, it would have a catastrophic impact on the exploration. Thus on-board technologies would still be more traditional than what a laboratory environment has sought. The autonomous rovers will considerably increase the productivity of crew. Responsibility for their own well-being is also useful for the rovers: to prevent getting hurt, to recognize and correct recoverable hardware and software faults.

Why the rainforest in Costa Rica is not rich with plants? Remember to use scientific language
Answers
Answer:
Deforestation is the major problem causing lack of rich species in Costa Rica. This is due to over grazing by cattle.This may lead to flooding which affect fertility of the soil.These animals graze on the plants without regulations,and cause erosion as their hoofs percolate the soil, further reducing soil fertility.
In addition to sustain the beef production, trees were fell to for cattle ranching.This ultimately contributed to loss of the forest species.
Banana plantation is an additional factor.Forest were cleared to cultivate banana, which affects forest population.

Answers
Answer:
To understand what era the Eocene period belongs to on the geologic time scale, the scientist would have to examine the Cenozoic era to understand all information related to it.
Explanation:
First, let's start with an explanation of terms.
MYA simply means Millions of Years Ago Time Scale is a sequence or organisation of events which is used as a yardstick to measure the duration of history or how long the earth has existed. Eocene Period refers to the geological epoch that lasted from about fifty-six to approximately forty MYA. It is also defined as the second epoch of the Paleogene Period within the modern Cenozoic Era.
Given the definition of the Eocene Period, to understand what era an Eocene period belongs to, the person must carefully study the Cenozoic era.
