Answer: Rosalind Franklin discovered the density of DNA and, more importantly, established that the molecule existed in a helical conformation. Her work to make clearer X-ray patterns of DNA molecules laid the foundation for James Watson and Francis Crick's suggestion that DNA is a double-helix polymer in 1953.
Explanation:
Rosalind Franklin made numerous contributions to science in addition to helping to discover the structure of DNA, and in the field of virology, in coal-based materials, by using X-ray crystallography, in agriculture, etc.
What is the contribution of Rosalind Franklin?She was one of the greatest scientists who made significant contributions to the field of DNA by using X-ray crystallography, and apart from that, she also made contributions to the field of virology. As X-ray diffraction facilitates the study of the structure of viruses such as the tobacco mosaic virus and the polio virus and helps in understanding the replication of viruses, it is also helpful in the study of the structure of coal and other carbon-based materials.
Hence, Rosalind Franklin made numerous contributions to science in addition to helping to discover the structure of DNA, and in the field of virology, in coal-based materials, by using X-ray crystallography, in agriculture, etc.

I had biology last year lol. I remember something about this haha.
The theory of how the first cell came to be are based on two assumptions. What are those two assumptions?
Answer:
1. All living things are made up of cells.
2. Cells are the basic building blocks of life.
3. All cells come from preexisting cells created through the process of cell division.
As science evolved, three more components were added to the theory. Some biology classes don’t require you to know these parts of the cell theory because they weren’t part of the original definition, but it’s still useful to be aware of them:
4. Energy flow occurs within cells.
5. Hereditary information is passed from cell to cell.
6. All cells have the same basic chemical composition.
So what does the cell theory actually mean? Let’s break it down. The first part of the cell theory states that all living things are made up of cells. Anything that’s alive, from bacteria to plants to humans, is composed of cells. And what are cells? The literal definition is a cell is a group of organelles surrounded by a thin membrane.
The cell theory definition states that cells are the building blocks of life. Cells both make up all living things and run the processes needed for life. Your hair, skin, organs, etc. are all made up of cells. In fact, each person is estimated to be made up of nearly 40 trillion cells! Each part of a cell has a different function, and your cells are responsible for taking in nutrients, turning nutrients into energy, removing waste, and more. Basically, everything your body does, it does because cells are directing the action!
The third part of the cell theory definition states that all cells come from preexisting cells. This means that cells don’t just appear out of thin air (known as “spontaneous generation”). New cells are always made from current cells. This means that all current life on the planet is descended from the very first cells, which first made an appearance on Earth roughly 3.5 billion years ago. Cells have been replicating themselves continuously ever since.
And what does the newer part of the cell theory state? Part four refers to the fact that, in all living cells, energy is continuously transformed from one type to another. Examples of these processes include photosynthesis (where plant cells convert light energy into chemical energy) and cellular respiration (where both plant and animal cells convert glucose into energy). Part five refers to DNA and the fact it is passed from parent cell to child cell. Finally, part six of the cell theory tells us that all cells are made up of the same chemicals: water, inorganic ions, and organic molecules.

How does interphase prepare cells for mitosis?
Answer:
Growth of cell and replication of DNA
Explanation:
[tex] \large{ \underline{ \bf{Interphase}}}[/tex]
It is a long, non-dividing, growing phase of the cell cycle, where the cell prepares itself for division.It represents the most active stage of the cell cycle where both cell growth and DNA replication occur in an orderly manner.It is the period of intense growth and synthesis in which a cell stocks all the biomolecules required during cell division.It is called the resting phase because there is no apparent activity related to cell division rather, it deals with the changes that occur in a cell and the nucleus, before it enters into cell division.Help me I need help pls

What are the Layers of the Earth?
The Earth is made up of three different layers:
1.The Crust
2.The Mantle
3. The Core
1. The Crust
It is the outer layer of the earth which is mainly composed of solid rock of basalt and granite. There are two types of crust which are oceanic and continental.
2. The Mantle
The mantle lies beneath the crust and is up to 2900 km thick and consists of hot, dense, solid rock containing iron and magnesium. The crust and the upper part of the mantle divide the lithosphere into both major and minor plates.
3. The Core
The core is the center of the Earth made up of two parts: the liquid outer core and the solid inner core. The outer core is made of nickel, iron and molten rock.
Thus, the inner core is hotter than the surface of the sun. So, the correct option is (C).

These cells secrete lymphocytes that are there to attack whatever is attacking our body. The gut immune cells and the microflora located inside it are responsible for preventing the growth of other microbes that are bad for us in the gut and to fight ingested pathogens that we can get on our food.
how are two processes from photorespiration related?
Answer:
Several physiological processes may be responsible for linking photorespiration and nitrogen assimilation. Photorespiration increases availability of NADH, which is required for the conversion of nitrate to nitrite.
Answer:
Two molecules are produced: a three-carbon compound, 3-PGA, and a two-carbon compound, phosphoglycolate. ... Photorespiration results in a loss of 3 fixed carbon atoms under these conditions, while the Calvin cycle results in a gain of 6 fixed carbon atoms.

Label the effect depicted in the picture below. How does
the picture connect to the definition?
(Amoeba sisters, video recap, genetic drift. Question number 2.)
Answer:
Bottle-necking effect.
Explanation:
Like in the picture below the bottlenecking effect works the same way in nature. When we shake the bottle some kinds of candies may fall out and some may not. This doesn't represent the whole bottle. Some type may not even fall out because the bottle wasn't wide enough for it to fall out. This can happen in nature too. In a forest fire where some animals survive they didn't survive because they were adapted to fire. They just weren't in the part of the forest that was on fire. So with the new allele frequency in the new population, this is a bottleneck effect.
Describe the famous experiment related to gravity that Galileo may have preformed. Include the results. Also, state whether the results support the law of gravity. Explain your answer.
Please help me please and thank you Id appreciate it very much.
Answer:
Galileo threw two balls from a tower's summit. They were both the same size and shape, yet one weighed 50 grams and the other weighed 500 grams. As a result, the two balls collided at precisely the same time. This finding backs up Newton's law of gravitation, which states that things with more mass will be subjected to a larger gravitational force. Because the 500-g ball has higher inertia, it takes more force to accelerate it. That force is provided by the stronger gravitational pull, and the two balls descend at the same rate.
Explanation:
One of the famous experiments often associated with Galileo Galilei is the experiment involving objects of different masses dropped from the Leaning Tower of Pisa. While there is some debate regarding whether Galileo actually conducted this specific experiment, it is often attributed to him for its conceptual importance.
According to the account, Galileo dropped two objects of different masses, such as a heavy cannonball and a lighter musket ball, from the top of the Leaning Tower of Pisa. The experiment aimed to determine whether objects of different masses would fall at different rates, as was commonly believed at the time. The expected result, based on the Aristotelian view prevailing during Galileo's time, would have been that the heavier object (the cannonball) would have fallen faster than the lighter one (the musket ball).
