Different cell types can react differently to epinephrine in the human body. Choose two cell types in the human body and briefly describe the cellular effect that occurs in the presence of epinephrine.

Answers

Answer:

I haven't really learned about cell types but I did find this information

Explanation:

How can epinephrine have different effects on different cells? Different cells have different receptors that bind epinephrine. Different cells activate different enzymes as a result of epinephrine binding.

epinephrine induces increased vascular smooth muscle contraction, pupillary dilator muscle contraction, and intestinal sphincter muscle contraction. Other significant effects include increased heart rate, myocardial contractility, and renin release

Intro

✓ Done

Answers

Answer:

Hydrophobic areas move away from water.

Hydrophilic areas are attracted to water.

Hydrophilic regions of the protein are attracted to other hydrophilic regions.

Explanation:

Proteins are made up of amino acids. The side chains of these amino acids determine whether they are polar or non-polar.  Hydrophilic amino acids are the types that are soluble in water and their side chains are polar. They are attracted to protein parts that are water-soluble.  Examples are Glutamate and Lysine.

The hydrophobic amino acids have non-polar side chains. They withdraw from water by taking on an oily form.  They are attracted to parts of the protein that are not aqueous. Examples are Valine and Tyrosine.

Answer:

1. Hydrophobic areas move away from water.

2. Hydrophilic areas are attracted to water.

5. Hydrophobic and hydrophilic interactions cause protein folding.

Herbicides are being used to kill weeds in a nearby field. The plants absorb the herbicides from the soil. Which organelle
in the plant will most likely store the absorbed herbicide waste?
ribosome
vacuole
chloroplast
mitochondrion

Answers

Answer:

The answer is B. Vacuole

Explanation:

As the plants have no used for the herbicides, it will be transported to it "waste bin" which is the Vacuole.

Definition of Vacuole: Vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance. Sometimes a single vacuole can take up most of the interior space of the plant cell.

Also, completed a test with same question, and got it right.

Vacuole organelle in the plant will most likely store the absorbed herbicide waste.

What is Vacuole?

Animal, plant, bacterial, protist, and fungal cells all include vacuoles. It has the size of a giant sac and is one of the biggest organelles found in cells.

Vacuoles are bordered by a thin membrane and filled with fluid and any molecules they take in.

This is their basic structure. Because both are membrane-bound sacs, they resemble another organelle called vesicles, however vacuoles are substantially bigger than vesicles and are created when numerous vesicles fuse together.

Therefore, Vacuole organelle in the plant will most likely store the absorbed herbicide waste.

How the coin flip relates to the probability of inheriting genetic condition?

Answers

Answer:

A coin represents a diploid, heterozygous cell with its heads and tails sides. The act of tossing the coin to land on heads or tails, provides an apt representation of the segregation of alleles during meiosis in the formation of gametes.

or i guess you could just say its all by chance ;P

peace :)

Answer:

It is very similar to the way traits are inherited in nature, as both combinations occur by chance. Though, in the coin toss, there are only 2 possible alleles whereas in nature there may be more complicated combinations of alleles for traits.

The population in a 50 square mile area is 200 people. What is the population density?

Answers

Answer:

[tex]\rho _{population}=4\frac{people}{mi^2}[/tex]

Explanation:

Hello.

In this case, since the population density is computed by dividing the amount of people by the space (area) where they are in:

[tex]\rho _{population}=\frac{people}{area}[/tex]

For 200 people living in a 50-mi² area, the population density is:

[tex]\rho _{population}=\frac{200people}{50mi^2}\\\\\rho _{population}=4\frac{people}{mi^2}[/tex]

It means that 4 people live per square mile area.

A predatory fish evolves adaptations that make it more adept at catching smaller fish. In turn, the smaller fish evolve means to be evasive, leading to more selection on the predators to be still better able to catch their prey. The interaction between the two species is an example of a(n)

Answers

Answer:

an evolutionary race (i.e., coevolution)

Explanation:

Coevolution is a phenomenon where two or more species affect each other's evolution through the mechanism of natural selection. During coevolution, species start an evolutionary race, where one species adapt and change (i.e., evolve) in response to another species, thereby countering the adaptive effects of the first one. An example of coevolution is the evolutionary race between predators and preys, like the example above.

The interaction between the two species is an example of a(n) coevolution. To understand more about it......

Arms race

In the coevolutionary arms race, there is selection pressure on both prey and predator. The predator evolves to catch the prey, and mutually the prey evolves to escape the predator. These arms race can be seen in Cenozoic mammals, where the size of the brains of predators and prey increased relatively over time. As the brain size of predators grew to become smarter to catch prey, the brain size of prey also grew to become smarter and able to escape predators. This process is called climbing coevolution, where predator adaptations are neutralized by prey adaptations, with no advance occurring. As a result, current predators are no better at capturing their prey than ancestral predators. Different from what happens in the evolutionary process, where evolution generates organisms that are better adapted than others

With this information, we can say that the coevolution of predator and prey is common in nature, and determines the survival of these species involved.
