According to the data in the table, what percent of the elodea cells is water? Explain how you arrived at this conclusion.
Answers
Answer:
99%
Explanation:
at a salt solution concentration of 2%, plasmolysis first started to occur. So the other 98% in the "solution" would have just been water. Since water inside cells needs to be greater than the amount of water outside the cells, we can say that the amount of water inside the elodea cells was 99% so that it can allow hypertonic plasmolysis to occur.

In biometry the structural dimensions of the biomolecules is studied. This way the biochemistry is linked with biometry.
Summarize cell division in prokaryotes
Answers
According to the research, the correct answer is that unicellular living beings like prokaryotes have their cell division by binary fission, forming two identical individuals (daughter cells).
What is binary fission?It refers to the process of cell division where first the deoxyribonucleic acid (DNA) is duplicated and then cytonesis occurs, which involves the separation of the cytoplasm.
In this sense, it gives rise to two daughter cells with identical genetic material, this is the reproduction method shared by certain yeasts, algae, bacteria and other prokaryotic organisms.
Therefore, we can conclude that the cell division mechanism of prokaryotes is through binary fission where two daughter cells arise.

A body cell has been growing and synthesizing proteins. In the nucleus of this body cell, DNA replication is taking place, and a copy of the cell's genetic material is copied. Which of the following is the best conclusion you can make about the life cycle of this cell?
Answers
The best conclusion you can make about the life cycle of this cell is that the cell is in the S phase of interphase and will move next to the G2 phase.
S phase (Synthesis Phase) is the phase of the cell cycle in which all of the chromosomes (DNA) are replicated within the nucleus. During this phase, the DNA is effectively doubled as each chromosome contains two sister chromatids. After the S phase, the cell enters the G2 phase where various proteins (such as microtubules) are synthesized.

Answers
Answer:
Star A
Explanation:
If you look directly at the diagram, the dwarf stars are labeled under 'A' and are the least in mass and temperature.
Being the smallest and coldest, dwarf stars most commonly have red coloration, which would make them the obvious choice.
Star A which is a dwarf star has the coldest temperature, and therefore is a red star since red stars are the coldest stars.
What are stars?Stars are a large self-luminous bodies whichbpriducw large amounts of heat energy and light energy as a result of the nuclear reactions occurring within them.
Stars have different colors and different sizes.
Red stars are the coldest stars and also the least massive.
From the chart, Star A which is a dwarf star has the coldest temperature, and therefore is a red star.
