Answer:
Rosalind Elsie Franklin (25 July 1920 – 16 April 1958)was a British biophysicist and X-ray crystallographer who made critical contributions to the understanding of the fine molecular structures of DNA, RNA, viruses, coal and graphite. The DNA work achieved the most fame because DNA (deoxyribonucleic acid) plays essential roles in cell metabolism and genetics, and the discovery of its structure helped scientists understand how genetic information is passed from parents to children.

Franklin is best known for her work on the X-ray diffraction images of DNA which led to discovery of DNA double helix. Her data, according to Francis Crick, was "the data we actually used" to formulate Crick and Watson's 1953 hypothesis regarding the structure of DNA.Franklin's X-ray diffraction image confirming the helical structure of DNA were shown to Watson without her approval or knowledge. Though this image and her accurate interpretation of the data provided valuable insight into the DNA structure, Franklin's scientific contributions to the discovery of the double helix are often overlooked. Unpublished drafts of her papers (written just as she was arranging to leave King's College London) show that she had independently determined the overall B-form of the DNA helix and the location of the phosphate groups on the outside of the structure. However, her work was published third, in the series of three DNA Nature articles, led by the paper of Watson and Crick which only hinted at her contribution to their hypothesis.
After finishing her portion of the DNA work, Franklin led pioneering work on the tobacco mosaic and polio viruses. She died in 1958 at the age of 37 from complications arising from ovarian cancer.

Use the reading below to answer the question.
The layer of soil above the permafrost is too shallow for plants with deep roots to live. Grasses and shrubs can survive there because they have shallow roots. A sheet of mosses and lichens grows beneath these plants. When the soil above the permafrost thaws, the soil becomes muddy. Muddy soil is an excellent place for insects, such as mosquitoes, to lay eggs. Many birds spend the summer in the tundra to feed on these insects.
Based on the passage, what is one reason for the lack of trees in the tundra?
A.
soil depth
B.
amount of rainfall
C.
temperature range
D.
amount of sunlight
Answer: I think it is amount of rainfall

The diffrents between an element molecule and a compond molecule is the type of atoms with whitch it is made true or false.
Answer:
true
Explanation:
because an element is of one type of an atom.
A molecule is made of two or more atoms held together by chemical bonds and if two atoms that form a molecule are of the same element form a diatomic molecule.
A molecule that consists of two or more atoms of different elements it forms a chemical compound.

Read the article excerpt below then answer the question.
How does burning carbon-containing fuels contribute to Earth’s climate change problem?
The chemical reaction that happens when ethanol and oxygen mix produces two substances: carbon dioxide and water in the gas phase. Since both of these are invisible, colorless gases, it seems like nothing is left of the liquid that was in your gas tank. However, the atoms of the reactants haven’t disappeared at all—they’ve only rearranged to form the products. The carbon dioxide and water produced by this chemical reaction enter the atmosphere whenever we burn ethanol or other carbon-containing fuels. In the recent past, humans have increased the amount of carbon dioxide in Earth’s atmosphere by burning such fuels, resulting in widespread changes to Earth’s climate. In response to these effects, scientists are working to find fuels that can release energy without producing carbon dioxide.
What are three types of scientists that would commonly use dichotomous keys to perform their job?
Answer:
Many scientists use dichotomous keys to identify plants, animals, and other organisms. They may also use dichotomous keys to identify species, or to determine whether a particular organism has been identified and described before. However, dichotomous keys are not used only to identify organisms.
Explanation: Scientists: Botantist, Cytoligist, Agronomist.
Hope this helps!!
Dichotomous keys are used in research to identify organisms like plants, animals, and microorganisms. Botanists, Agronomists, and Cytoligist can use dichotomous keys.
What are dichotomous keys?Dichotomous keys are the identification method of a group of organisms based on the alternative characters and divisions. They identify an organism based on immutable features.
Botanists study plants, Cytoligist study the function and structure of cells, and Agronomists study crop plants and soil. These types of scientists use the key to identify plants and animals.
Therefore, many scientists like Botanists, Agronomists, and Cytoligist use dichotomous keys.

1. How can systems with such different structures perform the same function?
2. How can different structures perform the same function?
Please help! And explain your answer with evidence please!
Explanation: Specialized Structures. ... This is because different organisms have developed unique structures that perform these functions and that do so in ways that fit their specific environments. So in this case, the structures are specialized to perform a specific function but also to fit the needs of a specific organism.
Due to unique structure an organism perform similar function if the structures are different.
Different structures perform the same function because different types of organisms have developed unique structures that helps them to perform function that is specific to their environments. The structures are specialized to perform a specific function but also to fit the needs of a specific organism.
Analogous structures refers to those structures which perform same function, but have different structures. Such type of organisms belongs to different ancestry but their body parts perform similar function so we can conclude that due to unique structure an organism perform similar function if the structures are different.

What is the crest and trough of a wave?
Answer:
Explanation:
A crest point on a wave is the maximum value of upward displacement within a cycle. A crest is a point on a surface wave where the displacement of the medium is at a maximum. A trough is the opposite of a crest, so the minimum or lowest point in a cycle. When the crests and troughs of two sine waves of equal amplitude and frequency intersect or collide, while being in phase with each other, the result is called constructive interference and the magnitudes double (above and below the line). When in antiphase – 180° out of phase – the result is destructive interference: the resulting wave is the undisturbed line having zero amplitude.

An airplane touches down on the runway at 37 m/s after 8 seconds, the airplane has slowed to a velocity of 5 m/s. what is a plane's acceleration?
Answer:
The acceleration is positive because they’re speeding up 4. An airplane touches down on the runway at 37m/s. After 8 seconds, the airplane has slowed to a velocity of 5 m/s.
Explanation:
Answer:
[tex]\boxed {\boxed {\sf a= -4 \ m/s^2}}[/tex]
Explanation:
Acceleration is the rate at which an object changes its velocity. It is the change in velocity over the change in time.
[tex]a= \frac{ \Delta v}{\Delta t}[/tex]
The change in velocity is the difference between the final velocity and the initial velocity.
Δv= final velocity - initial velocityThe airplane touches down at 37 meters per second, the slows to 5 meters per second. The final is 5 m/s and the initial is 37 m/s.
Δv= 5 m/s - 37 m/s= -32 m/sThe change in time is also how much time it took for the velocity to change. In this case, the change in time is 8 seconds.
Now we know the values for the variables:
Δv= -32 m/s Δt= 8 sSubstitute the values into the formula.
[tex]a= \frac{-32 \ m/s}{8 \ s}[/tex]
Divide.
[tex]a= -4 \ m/s /s[/tex]
[tex]a= -4 \ m/s^2[/tex]
The acceleration is -4 meters per square second. Since the acceleration is negative, the airplane is slowing down.
