You are testing learning and memory in two strains (A and B) of hamsters by determining which hamsters learn and remember how to navigate a maze better. You discover that a strain of hamsters raised in a diverse environment has enhanced memory compared to a strain of hamsters raised in a bare cage. You look at a specific gene that is involved in brain development and is activated during learning and memory. If you use bisulfite treatment and subsequent sequencing to study the methylation pattern is of the promoter for this gene, you find that at the same region of the promoter sequence:
Strain A has the following bisulfite treated sequence: GTACGTTAAACGATCG
Strain A has the following untreated sequence: GTACGTTAAACGATCG
Strain B has the following bisulfite treated sequence: GTATGTTAAATGATTG
Strain B has the following untreated sequence: GTACGTTAAACGATCG
Based on the sequences above, greater levels of transcription for this learning and memory gene more likely occur in which of the strains?

Answers

Answer 1

Answer:

The correct answer is - Strain B.

Explanation:

The methylation process is adding the methyl group to the DNA molecule that can alter the activity of the DNA segment without any change in the sequence. Methylation presence in the promotor in a gene can repress the transcription process.

By the sequence given it is clear that strain B is not treated and less likely to methylated whereas strain B is more likely to methylated so the greater transcribe sequence would be - Strain B.

When the blood glucose level decreases during a fast or between meals, the pancreas releases glucagon. Glucagon signals the liver to stop consuming glucose and to start producing glucose. Select the statements that describe how glucagon activates glucose production in the liver.

Answers

Answer:

Glucagon signals the liver to start producing glucose.

Explanation:

Glucagon signals the liver to start producing glucose from the breakdown of amino acids through gluconeogenesis process. When the glucose level decreases in the body due to fasting or starvation, the pancreas release glucagon which provides signals to the liver to produce glucose form non carbohydrates substances present in our body. This production of glucose increases the concentration of glucose in the blood and the body used this glucose for the generation of energy molecules in the form of ATP.

Town A half an hour later than Della
Both of them arrived in Town B at
the same time . Della drove at a
Speed of 60 km/h Find Nick's speed.
Plzz help mee​

Answers

Answer:

70 km/hr

Explanation:

Distance between town A and B = 210 km

Della's speed = 60 km/hr

Time taken by Della = distance / speed

Time taken by Della = 210 km / 60km/ hr

Time taken by Della = 3.5 hours

Since Nick left half an hour later Than Della ;

Then, Nick's travel time = 3.5 - 0.5 = 3 hours

Nick's average speed = Distance /time

Nick's average speed = 210 / 3 = 70km/hr

Explanation:

A large population of Yellow perch lives in the East river. The Walleye is a larger fish that eats the Yellow Perch. Despite lots of prey all the Walleye have moved from the East river to a new river. What most likely caused the Walleye to move to a different river?
(A)There is a lack of food in the East river which caused the Walleye to move to a different area.
(B) The Walleye are no longer able to catch the Yellow Perch and need to move to a different area.
(C)There is climate change which has caused the resources to decline in the East river.
(D) There is pollution in the East river that the Yellow Perch are adapted to but the Walleye are not.

Answers

Answer:

(D) There is pollution in the East river that the Yellow Perch are adapted to but the Walleye are not.

Explanation:

To ensure survival and cntinurd sustenance in an environment, there is need for an animal to posses certain features which would enable her cope with the conditions of the environment. The ability of animals to successfully live and survive in an environment is made possible through adaptation as the animal's adaptive features ensures the animal is able to live through and cope. If the adaptive features aren't suitable for such environment, then migration has to occurs, leading the animal to find a more suitable environment for survival. In the scenario above, the East river was presumed to be a good habitat for the Walleye and Yellow Perch, in spite of the available and abundance of food, the Walleye migrated, which is most likely due the fact that the Walleye lack the adaptive features to survive in the East river probably due to pollution which the Yellow Perch is well adapted to.

In the glycolytic pathway, the enzyme triose phosphate isomerase catalyzes the production of glyceraldehyde 3-phosphate (GAP) from dihydroxyacetone phosphate (DHAP). GAP continues through glycolysis via the reaction catalyzed by glyceraldehyde 3-phosphate dehydrogenase. In a muscle (myocyte) cell culture model, anaerobic conditions lead to cell death when triose phosphate isomerase is inhibited. In this same model, cells with inhibited triose phosphate isomerase survive under aerobic conditions. Briefly explain these findings including a discussion of energy production in anaerobic versus aerobic metabolism.

Answers

Answer:

In an anaerobic environment, organisms convert glucose into ethanol or lactate. In this condition, glycolysis generates 2 molecules of ATP and one molecule of NADH with the pyruvate. NADH molecule supports glycolysis by oxidized to NAD+ during the fermentation process.

Here one 6-C molecule breaks into two molecules G3P and DHAP, TPI or triose phosphate isomerase interconvert these two isomers and each triose is responsible for the production of two ATP molecules but if TPI is inhibited then there will be one ATP production which is not enough for supporting cellular process under the absence of oxygen and cell do not survive.

But in aerobic conditions pyruvate converted to acetyl CoA which produces 3 NADH, 1 FADH2, and 1 ATP that will get enough ATP by the oxidative phosphorylation hence will survive even if TPI is inhibited.

To dissolve the cell and nuclear membranes and release the DNA. To stabilize the DNA molecule so it doesn't fragment when dissolved in water. To keep the strawberries alive. To rinse off any dirt and pesticides that are on the strawberries.

Answers

Answer:

The correct answer is - To dissolve the cell and nuclear membranes and release the DNA.

Explanation:

The major function of the detergent in DNA extraction is to dissolve the cell and cellular membranes. It can increase the membrane permeability by pulling apart lipids and proteins that are components of the nuclear and cellular membrane and lyse the cell, from which we want to extract the DNA.

Detergents cause pores in the cell membranes and once these membranes are completely lysed the DNA is released from the cell. It is similar to detergents removes fat (lipids) from dishes.

Human blood contains a buffer of carbonic acid (H_2 CO_3) and bicarbonate anion (HCO_3^-) in order to maintain blood pH between 7.35 and 7.45, as a value higher than 7.8 or lower than 6.8 can lead to death. In this buffer, hydronium and bicarbonate anion are in equilibrium with carbonic acid. Furthermore, the carbonic acid in the first equilibrium can decompose into CO_2 gas and water, resulting in a second equilibrium system between carbonic acid and water. Because CO_2 is an important component of the blood buffer, its regulation in the body, as well as that of O_2 , is extremely important.
