Answer:
D) pleiotropy
Explanation:
Long QT syndrome is a type of syndrome which is characterized by having a long QT interval of the cardiac cycle.
Log QT syndrome occurs when the genes which control the formation of ion channels like sodium, potassium gets mutated as a result of which these channels are not formed or if formed are blocked. This slows down the ventricular repolarization as a result of which enough blood does not reach the organs.
The disease is genetical and is considered an autosomal recessive form. The gene for this is known as LQT and the associated genes are LQT7 and LQT8.
These associated genes produce additional symptoms along with long QT like short stature therefore these genes are considered pleiotropic where gene shows multiple effects.
Thus, Option-d is the correct answer.
Develop a hypothesis to explain why you think eurypterids developed legs even though they lived on the ocean floor.
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. Hope this helps.
The Eocene period exists in Earth’s history around 34 MYA. What could a scientist do to determine what era the Eocene period belongs to on the geologic time scale?
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.

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.
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
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.

Name the ionic compound PbCO3
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.

Why the rainforest in Costa Rica is not rich with plants? Remember to use scientific language
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.

Explain the relationship between mutations, adaptations,
natural selection, and extinction.
Answer:
Adaptations result from random mutations in the genes of organisms. Depending on the environment, these adaptations may be favorable or unfavorable. If an adaptation is favorable, it is selected by nature and, over time, more and more organisms in a population will have it. If the environment changes so much that the adaptations of a species are no longer enough for the species to survive, extinction will occur.

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.
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

What types of enzymes play a catalytic role in the regulation pathway of ubiquitination?
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.
