A species of eels that lives in the ocean can move up rivers to spawn. A freshwater pike is unable to move into the ocean from a river. Based on your knowledge of cellular membranes, explain why eels can move back and forth into the ocean, whereas pike cannot.

Answers

Answer:

Eels are a long, thin slimy fish that have a fin that runs the entire lengths of the backs of their bodies, extends around the tail and run for a distance on the underside of the fish. They have a wide and strong mouth. The pike has a long, slender body that is olive green in color and fades to yellowish-white on its belly. The reason for this is because they have diffrent bodies and a eel is small while pikes are big and have more weight.

ATP is to your cells as ______ is to a car

Answers

Answer:

Gas to a car

Explanation:

The ATP function in the cell is equal to the gas or fuel function in the car, as the ATP gives energy to the cell for different functions like the fuel gives energy to the car to move from one place to another.

 

What is the function of the ATP?

ATP is produced in the cell from the food that living organisms, such as animals and plants, consume and use to produce ATP. There are different reactions that together make ATP, such as glycolysis, the Krebs cycle, and the electron transport chain, and with the help of ATP synthase, ATP is made. It performs a variety of cellular functions, including protein synthesis, food digestion, message transmission from one cell to another, and so on.

Hence, the ATP function in the cell is equal to the gas or fuel function in the car, as the ATP gives energy to the cell for different functions.

Which statement describes how heat flows from the coffee to the part of the spoon in the coffee?

Heat flows from the coffee to the spoon through radiation.
Heat flows from the coffee to the spoon through convection.
Heat flows from the coffee to the spoon through conduction.
Heat flows from the coffee to the spoon through radiation, convection, and conduction.

Answers

Answer:

C. Heat flows from the coffee to the spoon through conduction.

The heat movement known to move from one area to elsewhere has been called heat transfer. Thermal conduction allows the coffee's heat to reach the spoon. Thus, option C is correct.

What is thermal conduction?

A type of heat transfer called thermal conduction occurs when heat flows from one spot to some other place due to the disparity in temperatures between the bodies.

When a body is subjected to thermal conduction, heat energy is dissipated from the body towards the colder or less heated objects. Because the spoon and coffee are at different temperatures, the heat from the coffee is passed to the spoon through conduction.

Therefore, thermal conduction is the process through which the coffee heats the spoon in the cup.

The drug Viagra promotes blood vessel dilation by prolonging signaling through nitric oxide (NO). How does Viagra boost NO?
a. It inhibits guanylyl cyclase in smooth muscle cells.
b. It prevents acetylcholine from binding to its receptors.
c. It stimulates guanylyl cyclase in smooth muscle cells.
d. It blocks the enzyme that degrades cyclic GMP.
e. It binds to acetylcholine receptors on endothelial cells.

Answers

Answer:

The correct answer is option d, that is, it prevents the enzyme, which degrades cyclic GMP.

Explanation:

Oral therapy for erectile dysfunction is Viagra, which is the citrate salt of sildenafil, it works by preventing a specific phosphodiesterase type 5 or PDE5, which is the inhibitor of cGMP. During sexual stimulation, nitrous oxide is released in the corpus cavernosum causing the erection of the penis in males. The nitrous oxide then stimulates the enzyme guanylate cyclase that further makes the concentration of cGMP to elevate, this generates smooth muscle relaxation in the corpus cavernosum and permitting blood the inward flow of blood.

Viagra works by increasing the influence of nitric acid by preventing PDE5, which is accountable for the deprivation of cGMP in the corpus cavernosum. At the time of sexual stimulation, the discharging of nitrous oxide takes place, the viagra inhibits PDE5 causing the levels of cGMP to elevate in the corpus cavernosum leading to smooth muscle relaxation and continuous flow of blood to the corpus cavernosum.

how energy is recycled in an ecosystem. how our atmosphere maintains its temperature. the importance of decomposers in an ecosystem. the one-way flow of energy in an ecosystem.

Answers

Answer:

The flow of energy in ecosystems is unidirectional or one-way.

Explanation:

Energy is the ability to do work. Energy flows in one direction in an ecosystem and is not recycled. This is because during the transfer of energy from one level to another, energy is lost. Most of the energy received from the sun by producers, plants, is lost as heat to the surroundings. The rest energy is converted by plants to produce food in the form of chemical energy.

Primary consumers feed on plants and secondary consumers feed on the primary consumers and so on up to quaternary consumers. However, at each level of energy transfer, some energy is lost as heat during respiration, some as unused or undigested materials, while some others are used for each organisms metabolic activities. About 90% of energy in a trophic is used at that trophic level. Therefore, only about 10% as much energy is available to  organisms at each successive trophic level. Therefore, energy is not recycled in ecosystems.

Earth's atmosphere maintains its temperature by means of the earth's energy balance. This refers to how incoming from the sun and outgoing energy from the earth are in balance, thereby keeping earth's temperature constant.

Decomposers, are organisms such as bacteria, fungi, and small animals such as ants and worms that eat and decompose dead and waste organic matter and which recycle nutrients back into food chains making them available for plants use. Therefore, decomposers are an essential components of all ecosystems.

For a quantitative trait explained by four loci in an additive fashion, if the four locus genotype AaBbCcDd corresponds to a phenotypic value of 32, and the four locus genotype AABBCCdd corresponds to a phenotypic value of 48, then what is the phenotypic value corresponding to the four locus genotype AABbcCDD?

Answers

Answer:

48

Explanation:

In genetics, additive effects represent a mode of quantitative inheritance that occurs when the combined effects of alleles (i.e., the variants of a gene that lead to differential expression of a phenotypic trait) at two or more loci are equal to the sum of their individual effects, contributing thus to the final phenotype. Therefore, the additive variance can be explained by the sum of the individual effects of identified loci/genes that have an additive effect on this quantitative trait. In this case, each gene shows an additive effect (equal to 8 for each dominant allele), thereby the phenotypic value corresponding to the genotype AABbCcDD will be equal to 48 (i.e., 16 + 8 + 8 + 16 = 48).

What Happens When a Recessive Allele Is Present More Than the Dominant?

Answers

Answer:

Then the Recessive trait is passed down to the offspring.

What does this process lead to?
Chiasma

Answers

Answer: Chiasmata are specialized chromatin structures that link homologous chromosomes together until anaphase I (Figs. 45.1 and 45.10). They form at sites where programmed DNA breaks generated by Spo11 undergo the full recombination pathway to generate crossovers. At a given chiasma, an exchange of genetic material can occur between both chromatids, what is called a chromosomal crossover, but this is much more frequent during meiosis than mitosis. In meiosis, absence of a chiasma generally results in improper chromosomal segregation and aneuploidy.

Why are seals able to live the coast of Antarctica while frogs snakes, and panthers not?


A. Seals can swim

B.seals are predators

C.seals have fur and blubber

D.seals are warm-blooded animals

Answers

Tbh it’s either c or d because c and d are both correct
The answer is C. My answer is because A and B are irrelevant to the question, so for that it can be eliminated. But between C and D, C makes much sense. Although D, says that seals are warm blooded and is true, however frogs (amphibians) and snakes (reptiles) they are cold blooded. They need sun in order to feel warm or the heat to adjust or accommodate their bodies temperatures, unlike panthers and seals they’re warm blooded they naturally have fur and are able to regulate their bodies temperature. Therefore D is eliminated. The correct answer is C, because seals have fur and blubber it’s much more durable, and are almost as if impenetrable for the freezing water and colder weather to pass through their fur. That is why they are able to live the coast of Antarctica.

The correct answer is C.

Do you believe that all of our actions can be attributed to the nervous system? Does your memory of an event trigger your responses? Why or why not?

Answers

Answer:

The nervous system is made up of all the nerve cells in your body. It is through the nervous system that we communicate with the outside world and, at the same time, many mechanisms inside our body are controlled. The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain. For example, if you touch a hot plate, you reflexively pull back your hand and your nerves simultaneously send pain signals to your brain. Metabolic processes are also controlled by the nervous system.
