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 Unpublished drafts of her papers (written just as she was arranging to leave King's College London) show that she had independently determined the overall B-form of the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.

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.

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.

If an object is placed in water and has a density of 1.9 g/ml will the object float or sink?
Answer:
float
Explanation:
since everything that have a density more than 1g/l (not g/ml) will sink and less than that will float
then 1.9g/ml < 1g/l
Answer:
it would sink
Explanation: it would sink because the density of water is 0.997 m/ml and 1.9 is more then that

Answer: i dont know either
Explanation:
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.

Explain how convection currents drive tectonic plate movement. In your answer, describe the role of energy transfer in the movement of tectonic plates.
Convection currents drive the movement of Earth's rigid tectonic plates in the planet's fluid molten mantle. In places where convection currents rise up towards the crust's surface, tectonic plates move away from each other in a process known as seafloor spreading
Answer:
The convection currents are what causes the movement of the tectonic plates. These currents occur in the mantle layer. Basically, the convection currents are a circular movement of the magma in the mantle which is cause by the difference in temperature and density. The hotter magma moves up because it is less dense, while the cooler magma moves down because it is more dense. This movement continues all the time. The magma that moves up comes in touch with the crust above it. At certain places where the crust is thinner, or there are cracks, under the big pressure from the mantle, the magma manages to penetrate through it, filling up the gaps, and also pushing the plates away. As the plates are pushed more and more, their opposite ends collide with other plates, resulting in subduction, so the crust is getting into the mantle and melts, moving down in the mantle as it is becoming cooler and denser magma, and the process continues on and on.

What measures the energy of a wave?
Answer:
ampiltude
Explanation:
Amplitude means a measure of the amount of energy in a wave. Notice in the drawing below how the amplitude measures the height a wave is going above or below the resting position of the wave.
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.
