Answer:
True
Explanation:
Microvilli: The cells on the villi are packed full of tiny hairlike structures called microvilli. This helps increase the surface of each individual cell, meaning that each cell can absorb more nutrients.
Answer: TRUE
Explanation: Villi are folds on the small intestine lining that increase the surface area to facilitate the absorption of nutrients. Absorptive cells that line the small intestine have microvilli, small projections that increase surface area and aid in the absorption of food.
So, the correct option is 'True'.

Why do we add detergent to the strawberries? Group of answer choices To dissolve proteins that are found on the DNA molecule and release the DNA from those proteins. 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.
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.

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.
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.

Amplify The temperature of the areas surrounding Farmington before Storm 1 and before Storm 2 was about 8°C, and there was the same amount of water vapor in the air. Storm 1 had more rainfall than Storm 2. Farmington Before Storm 1: Photograph of farmland on a clear day, with a blank response box containing a question mark. The air temperature is 8° Celsius. Before Storm 2: The same scene with an air parcel in place of the blank response box. The temperature inside the air parcel is 19° Celsius and outside is 8° Celsius. Arrows labeled wind frame the air parcel, pointing inwards. What were the conditions before Storm 1, and why did more rain fall with those conditions?
Storm 1. The air parcel at the surface was warmer and had more energy, so when it moved higher, it lost more energy.
The condition before storm 1 should be that the air parcel of the surface should be considered as the warmer and contain more energy.
What are weather patterns?It means the repeated way with regard to the weather that could be occur for days or it can be for the weeks also . It should be leads by heat from the sun and the movement can be done from the air.
Moreover, in the storm 1, the air parcel of the surface should be considered as the warmer and contain more energy. Due to this, it should high and lost the energy.

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.
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.

Answer:
c i think
Explanation:
the populations decrease as you go from the bottom of the food chain to top. Why do you think is so
Answer:
The reason is so there isn't an overpopulation of predators, or not enough food to sustain them. For example: there is lots of grass for rabbits to eat, comparing that to their predator like a snake, there isn't as much rabbits for them to eat.

Della and Nick drove at constant
speed from town A to town B along
the same road. The distance between the
two towns was 210 km. Nick left
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
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
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.
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.
