Explain the consequences to protein synthesis of the prokaryotic chromosome being free in the cytoplasm:
The regulation of protein synthesis is NOT strict as in eukaryotes. It is due to the lack of cell nuclei.
What are prokaryotes?Prokaryotes are simple unicellular organisms that lack cell nuclei and membrane-bound organelles.
Conversely, eukaryotic cells contain a cell nucleus where the process of transcription (DNA >> RNA) takes place.
The absence of compartmentalization of the genetic material makes the process of transcription simpler in prokaryotes than eukaryotes.

what is the difference between a stem cell and a differentiated cell,such as a red blood cells?
Answer: Stem cells can become a variety of types of cells, while differentiated cells like red blood cells are fully specialized cell types.
A stem cell produces a mesoderm cell, which can then further differentiate to form a muscle stem cell.
Stem cells are the unspecialized cells which are capable of self-renewing and differentiating into mature cells while differentiated cells are specialized to perform a specified function in the body.
Stem cells have the potential to become any type of cell once they are further along in development. Differentiated cells, on the other hand, already have a set purpose and can only become one type of cell when they develop and mature.
Explanation: Hope this helps! Please tell me if anything is wrong. <3
The difference between a stem cell and other cells like red blood cells is stem cells are unspecialized cells that are capable of self-renewing and differentiating into mature cells.
What are stem cells?Using additional differentiation, a mesoderm cell produced by a stem cell can develop into a muscle stem cell.
While differentiated cells are specialized to carry out a certain function in the body, stem cells are the unspecialized cells that are capable of self-renewal and differentiation into mature cells.
Once they reach a later stage of development, stem cells have the capacity to evolve into any form of cell. Differentiated cells, on the other hand, have a predetermined function and can only develop into one type of cell.
Therefore, differentiated cells, such as red blood cells, are fully specialized cell types, whereas stem cells can develop into a range of cell types.

Estella spilled tomato sauce on her shirt. When she washed her shirt, she noticed that the detergent she used contained enzymes. Enzymes are added to detergents to break down proteins from food and other substances that may stain clothing. Which would MOST likely inhibit the ability of the enzymes to remove the stain on her shirt?
Answer:
the temperature of the water
Explanation:
Enzymes have a defined temperature range at which they work the best. At temperatures outside of this range, the enzymes will not work well.
At high temperatures, enzymes can become denatured, meaning their structure is destroyed and they will have no activity.

How did Lamarck influence Darwin? How was Darwin's view of evolution different than Lamarck's?
Unlike Darwin, Lamarck held that evolution was a constant process of striving toward greater complexity and perfection. Even though this belief eventually gave way to Darwin's theory of natural selection acting on random variation, Lamarck is credited with helping put evolution on the map and with acknowledging that the environment plays a role in shaping the species that live in it.
Lamarck believed that living things evolved in a continuously upward direction, from dead matter, through simple to more complex forms, toward human "perfection." Species didn't die out in extinctions, Lamarck claimed. Instead, they changed into other species.
