g A team of researchers suspects that RegX may play a role in regulating cytoskeletal reorganization by activating KinY. To test whether these two proteins can interact, they conducted two variations of the following experiment: 1) Transform mouse cells with expression plasmids encoding the proteins of interest. 2) Express proteins of interest inside cells. 3) Lyse cells 4) Conduct a Co-IP on the cell lysate against GST or GST-tagged KinY (depending on the specific experiment). 5) Run western blots to see which proteins are present in the immunoprecipitates. The results _________________________________________.
Answer:
It is expected to observe the immunoprecipitation of the GST-tagged KinY complex, thereby indicating the role of RegX in the mechanism of cytoskeletal reorganization.
Expanation:
Western blot is a technique widely used in molecular biology laboratories in order to identify proteins and also to quantify their expression levels. This technique is useful to detect proteins with high specificity, in this case the technique has been used for the detection of an immunoprecipitated (i.e., GST-tagged KinY complex) in order to confirm the role of the upstream protein RegX in cytoskeletal organization.
Which is not part of the recipe for a thunderstorm to form?
O A. Unstable air
OB. A lifting force
O C. Moisture in the low atmosphere
O D. A cold front advancing
A cold front advancing is not part of the recipe for a thunderstorm to form.
How thunderstorms are formed ?
The same factors are required for each thunderstorm: lift, unstable air, and moisture. Oceans usually provide moisture. When warm, moist air is close to the ground and cold, dry air is above, unstable air forms. Lift comes from contrasts in air thickness. It raises unstable air, resulting in the formation of a large thunderstorm cloud.Commonplace wellspring of dampness for tempests are the seas. However, the amount of moisture that is added to the atmosphere is heavily influenced by the temperature of the water. Air is considered unstable if it continues to rise or sink when given a push. Warm, moist air near the surface and cold, dry air above indicate an unstable air mass.A piece of air or a bubble will continue to rise on its own in these circumstances if it is pushed upward. This parcel will cool as it rises, and some of the water vapor will condense, forming the typical thunderstorm's tall cumulonimbus cloud.Most of the time, in order for a thunderstorm to form, there needs to be something that pushes the air upward and starts the upward motion. Air density is the direct cause of this push upward.Different air densities result from the transfer of some of the sun's surface heating energy into the atmosphere. As the density decreases, the tendency for air to rise increases. The primary source of lift is this difference in air density, which can be achieved in a variety of ways.To know more about thunderstorms check this:

In Florida, soapberry bugs have historically fed upon balloon vine fruits, which produce large fruits. Soapberry bugs that feed on these fruits have relatively long mouthparts. After the goldenrain tree was introduced as an ornamental plant in Florida, some populations of soapberry bugs became specialists and ate only goldenrain tree fruits, which produce small fruits. These specialized soapberry bug populations, on average, have shorter mouthparts than the populations that feed on balloon vine fruits. If a population of soapberry bugs from a balloon vine were experimentally moved to a goldenrain tree, what would you expect to happen over time?In your answer, include definitions of natural selection and evolution in your own words.
Answer:
It is expected that the introduced population decreases because they have a minor adaptive response to survive in this new environment in comparison to its competence (i.e., specialized populations of soapberry bugs).
Explanation:
Natural selection is represented by the evolutionary processes that will select for survival to those individuals with higher adaptive fitness, which in this case is represented by the ability to obtain resources (food). In concequence, and according to the evolution theory, these introduced individuals will have less chances to reproduce in order to perpetuate their genes in the next generation.

Answer:
B. Hardness
Explanation:
Physical properties of a substance is defined as the properties which can be observed or measured without changing the composition of matter.
Physical properties include odor, appearance, color, texture, boiling point, melting point and many others.
Hardness is a physical property of a substance as it describes the resistance of substance to deformation and can be observed by simple touch or without changing the composition of matter.
While reactivity, toxicity and flammability are chemical properties of substances that change one type of matter into another type.
Hence, the correct option is B.
You decide to perform a chromatin immunoprecipitation to see whether your favorite gene, the Cool gene, is associated with H3 histones that are methylated at lysine 9 (on the histone tail).
You then want to determine whether this methylation also means that expression of the Cool gene is inhibited in cells.
1. Which of the following techniques will allow you to answer this question?
O Northern blot
O DNA footprinting
O Yeast 2 Hybrid
O Quantitative RT-PCR
O Microaray
O Hybridization
Answer:
Quantitative RT-PCR
Explanation:
Reverse transcription polymerase chain reaction (RT-PCR), also known as quantitative Real-Time (RT) PCR, is a technique widely used in molecular biology laboratories in order to assess the expression level of target genes. This technique employs a transcriptase inverse that enables to obtain DNA from total RNA and then this total DNA is amplified as in a Polymerase Chain Reaction. The levels of the target genes are obtained by comparing their relative expression with one or more control genes.
Why do you think the snapper population changed the way it did?
Answer:
Snapper population is decreasing
Explanation:
The population is decreasing since the human population is increasing dramatically. As the human population increases, the demand for fish and seafood also increases since humans eat seafood and fish. As the demand for fish increases, fishermen fish for these snappers more often and in bigger loads. Snappers cant reproduce faster than these fishermen are hunting for them and so the population decreases
Which statements describe attributes of an artisan well? Select two options
Answer:
B. uses natural pressure
E. has groundwater stuck between impermeable layers
Explanation:
Artesian well has the same attributes of having the presence of water like that of a regular well. The major difference is that the artesian well has water which comes out to the surface without the application of pressure. This is due to the presence of a positive pressure within the underlying rocks and its environs which forces the water out to the surface.
It has natural pressure and doesn’t require a pump and it also has groundwater stuck between impermeable layers.

Explanation:
A lethargic 22-month old black female was presented by her mother to the emergency room at 2:15 am on a Sunday. The child had a history of a runny nose, hoarse cough and low-grade fever (~99F) for the past 48 hours. The mother was concerned about the forced and noisy breathing of the child. The pediatrician examined the child and found cloudy eyes and mild inflammation of the ears, but no overt signs of bacterial infection (no significant changes in the eardrums). The throat of the child was red and coated with mucus. The larynx was swollen and raw.
The physician performed a rapid Strep Test*, and found it was negative. Throat swabs were taken for culture. The physician placed the child in a room with a warm vaponzer for about 30 minutes. This dramatically improved the breathing of the child.
rapid Strep test* is used in the diagnosis of bacterial pharyngitis caused by group A streptococci (GAS), sometimes termed strep throat.
Questions:
1. What is the presumptive diagnosis for this case?
2. Will the throat cultures likely show evidence of Streptococcus pyogenes? How about Staphylococcus aureus?
3. Do you believe that this is a bacterial or viral disease? Why?
4. What further treatment might be indicated for this case?
Answer:
it is adenoviral pharyngitis, croup
No, due to the fact that the the Strep test was negative and the overall picture indicates a viral infection
it is a viral disease; this viral disease is characterized by little or no pus on pharynx, a good response to warm vapor to clear congestion
further treatment that is needed in this case is a more vapor treatment, decongestant, and analgesic; antibiotics should be reserved unless Strep of Hib shows on culture.
Explanation:
adenoviral pharyngitis,symptoms are usually, cough, fever, cough, sore throat e.t.c..
croup, known as laryngotracheobronchitis also is a viral respiratory infection which causes swelling inside the trachea, that hinders normal breathing process and symptoms include cough, stridor, and a hoarse voice.

Marsupial mole rats evolved in New Zealand in the 1700s and had few natural predators so they overpopulated the area. Scientist developed a virus to bring their numbers down, which was successful for awhile. After several generations though, their numbers began to increase. Why? *
A. Marsupial mole rats mated with other mole rats and created a new species.
B. Marsupial mole rats learned to survive regardless of being sick.
C. Some marsupial mole rats had a natural immunity to the virus.
d. Marsupial mole rats changed their reproductive cycle and were able to reproduce more.
Answer:
C. Some marsupial mole rats had a natural immunity to the virus.
Explanation:
According to Darwin's evolutionary theory, over time some of marsupial moles may have acquired natural immunity which evolves as an adaptive trait in the population. Since these organisms have more chance to survive and reproduce (survival of the fittest), they will likely transmit the natural immunity to the next generation .

Research and identify a vestigial structure of an organism of your choosing.
Why does the organism not need that structure anymore? (Think about what the structure's original purpose was.)
Answer:
The one of best example would be appendix in humans.
Explanation:
In the past, the appendix may have helped in the digestion of the plants by producing mucus and prevent any type of infection. Plants with a high content of cellulose are digested with the help of the appendix as reported.
It is not a part of the human digestive system and considers as a vestigial organ. Vestigial organs are the organs that are present in an organism with no particular function and their removal will not lead to any harm. Humans do not need it because our digestive system is more efficient and works better in the first stages of digestion than they used to.
Thus, the correct answer is - appendix in humans.

What are the benefits of geothermal and oil-and-gas forms joining forces?
Explanation:
Geothermal energy is generally considered environmentally friendly and does not cause significant amounts of pollution.
Geothermal reservoirs are naturally replenished and therefore renewable (it is not possible to exhaust the resources).
Massive potential – upper estimates show a worldwide potential of 2 terawatts (TW).
Excellent for meeting the base load energy demand (as opposed to other renewables such as wind and solar).
Great for heating and cooling – even small households can benefit.
Harnessing geothermal energy does not involve any fuels, which means less cost fluctuations and stable electricity prices.
Small footprint on land – can be built partially underground.
The geothermal sources of energy along with oil and gas are an additional source of energy and these sources help to meet the increasing demands of energy with reduced emissions.
What is geothermal energy?The heat generated within the earth is termed geothermal energy. The geothermal source is a renewable energy source. These sources include hot springs, hydrothermal vents, steam vents, and geysers. The heat from these sources can be captured and used directly or the steam is used to generate electricity.
Geothermal energy is useful in generating electricity as well as in heating and cooling applications. It is a renewable source of energy because the heat is continuously produced inside the earth. Therefore, it is a never-exhausting source of energy.
