Explanation:
How does heat flowing through Earth's layers contribute to the formation of an ocean basin?
Answer:
Moreover, the way that this works is that convection currents in the mantle causes tectonic plates to move when material near the Earth's core rises, and colder mantle rock sinks. Hot magma wells up at the ridges, forming new ocean crust and shoving the plates apart.
Explanation:
Which of the following do you see at a divergent plate boundary?

select characteristics exhibited by most bacteria and archaea to test your understanding of the differences between these microbes and eukaryotic organisms.
Some characteristics exhibited by most bacteria and archaea to test understanding of the differences between these microbes and eukaryotic organisms are nuclear membrane, ribosomes, membrane bound organelles, cell wall structure and size.
Bacteria and archaea comes under the prokaryotic organisms which are different in fundamental ways with the eukaryotic organisms.
The bacteria and archaea have smaller size as compared to eukaryotes. The prokaryotes have no defined nucleus and membrane bound organelles while eukaryotes have.
The cell wall structure of prokaryotes are more complex as compared to eukaryotes. The ribosomes in prokaryotes are smaller as compared to eukaryotes.

In expressing a mammalian gene in Escherichia coli, the most formidable obstacle is introns. Intron help in affecting the nuclear export, rate of transcription and transcript stability.
These introns are present in all eukaryotes as a gene structure and these introns are eliminated by complex molecule that is called spliceosome. The mammalian expression is system of choice that help in the function of a particular protein in most physiologically environment.
Introns are removed by the RNA splicing as RNA matures means these mRNA are not present in the final messenger RNA.
Spliceosome is the large RNA protein complex that help in the removal of introns from nuclear pre - mRNA.

Meristematic tissue has a number of defining features, including small cells, thin cell walls, large cell nuclei, absent or small vacuoles, and no intercellular spaces. The apical meristem (the growing tip) functions to trigger the growth of new cells in young seedlings at the tips of roots and shoots and forming buds.

Explanation:
Describe an example of fermentation that occurs in beneficial bacterial cells within animals and explain why it is important.
Fermentation is an anaerobic process in which energy can be released from glucose even though oxygen is not available. Fermentation occurs in yeast cells, and a form of fermentation takes place in bacteria and in the muscle cells of animals. In these situations, your working muscles generate ATP anaerobically (i.e., without oxygen) using a process called fermentation. Fermentation is beneficial in that it can generate ATP quickly for working muscle cells when oxygen is scarce. Fermentation helps break down nutrients in food, making them easier to digest than their unfermented counterparts. For example, lactose — the natural sugar in milk — is broken down during fermentation into simpler sugars — glucose and galactose ( 20 ).
Microbial fermentation takes place within the gastrointestinal tract of the majority of the animals by the bacterial cells, this helps in the process of digestion and in the synthesis of certain essential components like vitamins.
• The enzymatic decomposition and the usage of food components, mainly carbohydrates by the help of microbes like bacteria anaerobically is termed microbial fermentation.
• Within the gastrointestinal tract of the majority of animals, the process of fermentation takes place, however, the intensity of fermentation depends on the quantity of bacterial cells present, which is usually greatest in the intestine.
• The process of fermentation within the intestine by bacteria primarily helps in the process of metabolism and digestion of carbohydrates that does not get digested in the small intestine like residual starch and cellulose.
• Apart from this, microbial fermentation also helps in the production of vitamin K and some B vitamins.
Thus, microbial fermentation within the intestine of the majority of the animals performs essential functions like digestion and production of vitamins.

PLS HELP ASAP If an animal cell wasn't in an isotonic solution, wouldn't active transport be able to balance the cell's volume? If not, why?
Answer:
Animal cells tend to do best in an isotonic environment, plant cells tend to do best in
a hypotonic environment. This is demonstrated in the attached PDF.
Explanation:
A cell that does not have a rigid cell wall, such as a red blood cell, will swell and lyse (burst) when placed in a hypotonic solution, a process called cytolysis. Cells with a cell wall will swell when placed in a hypotonic solution, but once the cell is turgid (firm), the tough cell wall prevents any more water from entering the cell. When placed in a hypertonic solution, a cell without a cell wall will lose water to the environment, shrivel, and probably die. In a hypertonic solution, a cell with a cell wall will lose water too. The plasma membrane pulls away from the cell wall as it shrivels, a process called plasmolysis.
