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.

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.

Explanation:

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.

Answer: The main difference is that the geocentric has the Earth at the center, and the heliocentric has the sun at the center. The geocentric model says that the earth is at the center of the cosmos or universe, and the planets, the sun and the moon, and the stars circles around it. The early heliocentric models consider the sun as the center, and the planets revolve around the sun.

Reflex arcs

Sensory neuron sends electrical impulses to a relay neuron, which is located in the spinal cord of the CNS. Relay neurons connect sensory neurons to motor neurons. Motor neuron sends electrical impulses to an effector. Effector produces a response (muscle contracts to move hand away).

Explanation:

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.

Explanation

Answer:

The wrong protein can be created or the right one with abnormal function.

Explanation:

The mutated DNA is taken through the whole protein synthesis process and translated by the rRNA and tRNA to create a protein from that new sequence.

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:

Inside the air sacs, oxygen moves across paper-thin walls to tiny blood vessels called capillaries and into your blood. A protein called haemoglobin in the red blood cells then carries the oxygen around your body.

Answer: The bloodstream

Explanation:

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

Answer: 1. Primary producers use energy from the sun to produce their own food in the form of glucose, and then primary producers are eaten by primary consumers who are in turn eaten by secondary consumers, and so on, so that energy flows from one trophic level, or level of the food chain, to the next.First,the sun transfers heat to the plants,helping them grow.Animals such as deer who would eat grass,eat plants. 2. Initial Observations What was the health of the ecosystem of Atlas National Park like before wolves were reintroduced? Before the wolves, all species were outside their normal range. The ecosystem was not in equilibrium at all and slowly deteriorating. 3. Wolves are causing a trophic cascade of ecological change, including helping to increase beaver populations and bring back aspen, and vegetation. brainliest?

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.

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.
