Answer: Before DNA, she studied the holes in coal. She captured photograph 51. Franklin loved traveling and backpacking. After DNA, the discoveries continued with tobacco viruses. She worked until the last breath.
Explanation: 1. Before DNA, she studied the holes in coal.
Rosalind Franklin was born in the summer of 1920 in London into an affluent and educated family. From a young age, she showed exceptional talent and creativity that manifested in an early fascination with physics and chemistry. After college, she pursued a doctoral degree from Cambridge, and since this was during World War II, she worked on the porosity of coal for fuel purposes and other wartime devices. Her PhD thesis was titled, “The physical chemistry of solid organic colloids with special reference to coal.” After her PhD, she described herself while asking a friend about job openings as “a physical chemist who knows very little physical chemistry, but quite a lot about the holes in coal.”
2. She captured photograph 51.
You probably know that Watson and Crick published a paper in Nature in April 1953, proposing their model of DNA structure. You also know that they won the 1962 Nobel Prize for that paper. What you probably do not know is that in the same issue of Nature, there was a paper by Franklin and her doctoral trainee, Raymond Gosling. The paper was titled, “Molecular Configuration in Sodium Thymonucleate.”
The paper provided experimental evidence that supported some of Watson and Crick’s purely hypothetical arguments. Specifically, the famous photograph 51 shows that DNA is in fact helical. In the conclusion of the paper she wrote, “Thus our general ideas are not inconsistent with the model proposed by Watson and Crick in the preceding communication.”
Prior to the publication of this paper, photograph 51 was shown to Crick without Franklin’s consent, which is still the topic of a debate over ethics and the Nobel Prize, which is more broadly controversial for rarely recognizing women. However, Franklin was given due credit in Photograph 51, a 2015 play about her life, which starred Nicole Kidman.
3. Franklin loved traveling and backpacking.
Her love for science and discovery did not mean that she did not have hobbies. She traveled frequently to her favorite country, France, and backpacked through the French Alps.
She wrote to her mother in 1946,“I am quite sure I could wander happily in France forever. I love the people, the country and the food.” She also traveled to the US for work, where she had made many friends throughout the years.
4. After DNA, the discoveries continued with tobacco viruses.
Franklin’s colleagues at King’s College were getting more and more hostile towards her, calling her “Rosy” and “Dark lady” behind her back. In 1953, One of Franklin’s colleagues (and a Nobel laureate), Wilkins, wrote in a letter to Watson and Crick:
“I hope the smoke of witchcraft will soon be getting out of our eyes.”
The growing sexism she faced drove Franklin out of King’s college, and she moved to Birkbeck College the same year. At Birkbeck, she distanced herself from DNA and started to work on another fascinating molecule, RNA, a molecule that carries genetic information and just like DNA, is vital to life.
She used X-ray crystallography (a method to look at the shape of very small things like viruses) to explore the structure of the Tobacco Mosaic virus (TMV), an RNA virus that infects tobacco plants. Just a few years into this new arena of research, her team put together a clear model of TMV. Their model suggested that TMV is a barrel-shaped virus made up of proteins, with RNA molecules wrapped in the donut hole like a coiled rope. This work has since been extended to several other viruses, and has been fundamental to our understanding of viruses and RNA.
5. She worked until the last breath.
In 1956, Franklin was diagnosed with ovarian cancer and started chemotherapy. But nothing could stop DNA’s Dark Lady and her love for science. She published seven scientific papers in 1956, and went on to publish six more in 1957, all while she was undergoing chemotherapy. This is how the crystallography pioneer John D. Bernal described Franklin’s final months: “Her devotion to research showed itself at its finest in the last months of her life. Although stricken with an illness, which she knew would be fatal, she continued to work right up to the end.”
Franklin succumbed to cancer in April 1958, but her legacy continues to this day. Photograph 51 is in almost every biology textbook around the world. Perhaps she was not appreciated in her time, but the future won’t forget her.

Match each image to the correct cell of the cell cycle I will mark brainiest
Answer:
Interphase: Lowest pic, left corner.
Cell appears to be in a normal state.
Metaphase: Left, above Interphase.
Chromosomes are beginning to align in the middle of the cell. Spindles form and begin to attach to their centromeres.
Anaphase: Lowest right pic.
The chromatids are pulled away from each other and brought to different sides of the cell.
Telophase: Above Anaphase.
The genetic material is now in its respective side of the cell, which now begins to split into 2. Nucleic membrane begins to form.
Cytokinesis: Above Metaphase.
The clevage furrow is forming and separating the cytoplasm and other organelles in the cells. When done, this will result in 2 identical cells (unless it's meiosis II).
The matching of each image to the correct cell of the cell cycle is as follows:
Interphase: Most Last picture. Metaphase: Third picture. Anaphase: Fourth picture.Telophase: Second picture.Cytokinesis: First picture. What is the Cell cycle?The cell cycle may be defined as the entire sequence of events happening from the end of one nuclear division to the beginning of the next. It can significantly be divided into two phases. They are as follows:
Interphase.M-phase (Division phase).The Interphase of the cell cycle is the longest phase which consists of three phases. They are the G1 phase, S-phase, and G2 phase. In this phase, the cell replicates its genetic content and appears to be in a normal state.
In metaphase, the chromosomes usually align in one plane and form an equatorial plate. Anaphase is the smallest phase of mitotic cell division. In this phase, the centromere splits, and centromeres migrate to opposite poles.
In telophase, two sets of daughter chromosomes reached the opposite poles and are converted into chromatin thread. After karyokinesis, the cytoplasm gets converted into two equal parts. This is known as cytokinesis.
Therefore, the matching of each image to the correct cell of the cell cycle is well described above.

Suppose a scientist discovers fossils of ancient horses in an area. The fossilized horses are much smaller than modern horses. They are found in the same layer as many fossilized tree trunks. Today, horses still live in the area, but it is now open grassland.
How do you think the environment has changed over time, and how could this change have led modern horses to be larger than ancient horses?
Answer:
Well maybe most of the ancient horses died becuse of how small they were and had to evolve to survive and live longer. Probably.
Explanation:
Answer:I think the environment has changed because there were fossilized tree trunks found with it so that means that there used to be trees in the grassland areas. Maybe the horses were too small so they died or they didn't have enough food to survive off of.
Explanation:
Which statement best explains what happens to a leaf when it has lost much-needed water?
A. Its atmospheric pressure decreases.
B. Its rate of photosynthesis increases.
C. Its rate of transpiration increases.
D. Its turgor pressure decreases.
When a leaf loses much-needed water, its turgor pressure would decrease.
Turgor pressure is created in the cells of a leaf when there is enough water. The water stretches the cell membrane outward, creating a kind of pressure.
When the cells lose water, the cell membrane shrinks inward and loses the supporting pressure.
Thus, the turgor pressure created by the presence of water is lost by the absence of water.
The absence of water also affects the rate of photosynthesis and transpiration negatively and not positively. A leaf losing water has no bearing on the atmospheric pressure.

The flow chart below indicates the hierarchical levels of the Linnaean classification system.
Kingdom --> Phylum --> Class --> Order --> Family --> Genus --> Species
Which of the following organisms most likely share the most structural characteristics?
A.
Two organisms that are classified within the same genus, but different species.
B.
Two organisms that are classified within the same phylum, but different classes.
C.
Two organisms that are classified within the same kingdom, but different phyla.
D.
Two organisms that are classified within the same class, but different orders.
Answer:
the answer is A
The right response is A. two species of different creatures that belong to the same genus. This is so because the Linnaean Classification method uses a hierarchical method, with the most similar animals being placed in the same genus, to classify organisms according to their physical traits.
What is the reason for the same ?Consequently, due to their high degree of physical similarity, two animals belonging to the same genus are most likely to share the majority of their structural properties.
For instance, the genus Felis includes two species of cats, such as the domestic cat and the Bengal tiger. This indicates that their physical characteristics, such as having fur, four legs, and whiskers, are the most similar.
Comparatively, two species that belong to different phyla, classes, orders, or families are less likely to share the same structural properties since they are less closely related to one another and have fewer physical characteristics in common.
