Compare the function of phototropism to the function of gravitropism. How does each of
these tropisms work?

(Hint: starch molecules and auxins should be part of your response.)

Answers

The function of phototropism can be compared best with the function of gravitropism by taking an example of statoliths (Starch molecules) in roots and auxin in stem.

Roots often bend away from light (i.e., exhibit negative phototropism) in the direction of gravity(i.e. exhibit positive gravitropism).

Whereas stem-like organs drive their growth toward the light (i.e., positive phototropism) and away from gravity (i.e., negative gravitropism) (i.e. positive gravitropism).

As in the instance of phototropism, positive tropisms react by migrating towards the direction of the stimulus source.

Auxin formation and blue light stimulation control this response's mechanism.

On the shaded side of the plant, where those cells are starting to elongate, the activation of the blue light results in a concentration of auxin, a plant hormone.

On the other hand, negative tropisms, like gravitropism in plant shoots, react by migrating away from the stimulus's source.

A unique type of cell called a statocyst contains statoliths, which are starch molecules that can settle within the statocysts in reaction to gravity.

These starch molecules accumulate on the bottom of the statocyst as they descend toward gravity, increasing auxin levels and encouraging cell elongation.

Hence, these two processes can be compared best with an example of statoliths (Starch molecules) in roots and auxin in stem.

On your first research mission you make an amazing discovery by finding a new species living in the hostile environment of the sahara desert. after observing it carefully you determine that it is not an autotroph, it is multicellular, and it does not contain any chitin. what is the best classification for it? a. animalia b. eubacteria c. protista d. plantae

Answers

The best classification for this new species is Animalia.

According to the six kingdom classification given by Carl Woese, all organisms are divided into 6 kingdoms.

1) Archaebacteria

2) Eubacteria

3) Protista

4) Fungi

5) Plantae

6) Animalia

As the newly discovered species is a multicellular (made up of more than one cell) organism.

Then it can only belong to Kingdom Fungi, Plantae and Animalia as the rest of the kingdoms like Archaebacteria, Eubacteria and Protista consist of unicellular organisms that are made up of only one type of cell.

Now this species is not autotrophic ( i.e. an organism that can get its own nutrition by the use of light, water, carbon dioxide, or other substances).

It means it is heterotrophic which means it can't get nutrition on its own.

Out of the Fungi, Plantae and Animalia , only fungi and Animalia kingdoms consist of heterotrophic organisms.

Now this species also does not contain chitin which is an important characteristics of Fungi.

So only option left is Animalia.

Which statement BEST describes how greenhouse gasses act as natural insulators in the Earth's system?

Answers

Hi there, your answer is below.

The gases absorb and emit a part of the heat reflected by the Earth's surface.

Solar radiation will pass through the atmosphere first in the greenhouse effect. Some of them will get through and touch the surface of the planet. Long-wave thermal radiation, which is what the greenhouse gases will absorb, will be produced when some of the energy that strikes the Earth's surface is transformed. They are returned to the Earth via greenhouse gases.

What are greenhouse gases, and why do they affect our environment?

The surface of the Earth would be much colder and have a "snowball Earth" if it weren't for the impact of greenhouse gases, primarily water vapor, carbon dioxide, and methane.

Because the greenhouse gases are generally transparent to the sun's incoming radiation, which is mostly in the visible light region of the spectrum, the greenhouse effect is able to take place. In contrast, the majority of the radiation that the Earth emits is in the infrared region of the spectrum, which is absorbed by greenhouse gases. Some of the radiation from these gases is redirected to the earth when it is later released. This traps it, warming the planet's surface in the process. The average temperature of the Earth would be -14 degrees Celsius without greenhouse gases.

Greenhouse gases have acted to even out temperature changes over Earth's history. Huge woods have thrived when the Earth experienced warmer times, as the Carboniferous epoch. These have taken in carbon dioxide from the air, storing the resultant carbon in the form of coal deposits underground. After a certain amount of carbon has been stored, the atmospheric concentration of carbon dioxide falls to very low levels, and the warming effect is eliminated. The trees perish as the globe cools.  Currently, plants are no longer removing carbon dioxide from the atmosphere, while volcanoes are still adding carbon dioxide to the atmosphere. The increase in carbon dioxide causes a rise in global warming. We are now recuperating from the last glacier, which ended roughly 10,000 years ago, during a mild time. In the past 120,000 years, the previous warm era peaked.

The ability of carbon dioxide to boost plant development is another crucial effect. Without the impact of the increased carbon dioxide concentration on crops, it is improbable that the Earth could support the 7 billion people that inhabit it now.

The amount of carbon stored in the atmosphere is rather tiny. There are currently 800 billion tons of carbon in it. But only approximately a quarter of this, or 210 billion tons, of the carbon gets recycled each year by plants and the seas. Consequently, the two-year half life of carbon in the atmosphere is rather short. Because there is such a tiny atmospheric carbon storage, people have a significant impact. Burning fossil fuels only adds roughly 9 billion tons annually. But throughout my lifetime, the concentration has increased by 30%, from around 300 parts per million in 1947 to 410 parts per million now, as a result of this modest increment each year. As a result, there has been a little but considerable increase in surface temperature as well as rising sea levels due to ice cap melting. Although the increase in sea levels over the past 70 years has only been around 9 inches, it is rising, and because so many people live near the coasts, we are susceptible.

Because the atmospheric carbon storage is so limited, it is possible to lower atmospheric carbon and prevent flooding in our coastal communities, for example by fertilizing the seas to improve their capacity to absorb carbon dioxide.

Thank you,

Eddie

What is DNA isolation/extraction?

Extraction of DNA is a common practice used to separate DNA from cell nuclei.

The process of DNA isolation involves-

Step 1: Cracking open cells to release DNA

The cells in a specimen are separated from one another, frequently by physical techniques like grinding or vacuum filtration, and then placed in a salt solution.

Step 2: Distinguishing DNA from protein and additional cellular waste

It's important to get rid of as much cellular waste as you can to obtain a pure DNA sample. There are numerous ways to accomplish this. To destroy DNA-associated protein and other cellular proteins, a protease (protein enzyme) is frequently introduced.

Step 3: Use an alcohol to precipitate the DNA

Finally, the DNA sample is carefully infused with ice-cold alcohol (whether ethanol or isopropanol). While salt and alcohol make DNA insoluble, it is soluble in water.

Step 4: DNA cleaning

Now that the DNA sample has been refined further (cleaned). Then it is ready for use after being resuspended in such a slightly alkaline buffer.

There are 3 possible genotypes: NN, MN, or MM. In a group of 500 people, the frequency of genotype NN is 40%. How many individuals would you expect to have the MN genotype

Answers

235 are the Individual numbers that would expect to have the MN type of genotype.

There are two equations necessary according to Hardy-Weinberg Equilibrium:-

p + q = 1

p² + 2pq + q² = 1

Let,

NN= p

NM=2pq

MM=q

So, according to the question, the frequency of genotype NN is 40%

40% of 500 = [tex]\frac{500*40}{100} = 200[/tex] Numbers of individuals

Frequency of individuals p = [tex]\frac{Numbers of individuals}{Total populations}[/tex] = [tex]\frac{200}{400} = 0.4[/tex]

Find p² by taking the square root of p.

√(p) = √(0.4)

= 0.632

So, pp + qq = 1  

qq = 1 - pp =  1 - 0.63

q = 0.37

The allele frequencies in the population are known, now finding the frequency of heterozygous genotype.

By Multiplying 2 × p ×q  to get heterozygous genotype

2pq =  2 × 0.63 × 0.37` = 0.47
