Answer:
hello
Explanation:
In 1831, when Darwin was just 22 years old, he set sail on a scientific expedition on a ship called the HMS Beagle. He was the naturalist on the voyage. As a naturalist, it was his job to observe and collect specimens of plants, animals, rocks, and fossils wherever the expedition went ashore.

Hello! Your answer is shown below,
Darwin’s presence on board the Beagle was supplementary if not ornamental to the official aims of the second voyage, which were to provide accurate charts for naval, commercial, and colonial navigation and to stake a British strategic claim around the shores of South America following the breakup of the Spanish and Portuguese empires.

What happens when proteins in egg white are denatured?.
|| ▼ Answer ▼ ||
When the egg white is denatured like what is done in frying or boiling an egg, the protein present in the egg white will be coagulated.
|| ✪ Explanation ✪ ||
The texture of the egg will change due to denaturation. With the application of heat, protein is coagulated by losing its bonds for its shape. When the egg is boiled, the protein present will group together making the egg texture hard. Denaturation of proteins contributes to the change of their structure and thereby losing their function.
Hope this Helps!
If you have any questions please ask.
Answer:
Denaturation of proteins in egg disrupts the tertiary structure of proteins.
Explanation:
The bond between the charged groups and the non-polar groups is altered. This takes place at high temperatures and it is an irreversible denaturation. it results to whitening of the albumen

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.

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.

What is unique about water on Earth?
Group of answer choices
All of the above.
Water has tremendous kinetic energy because of the strength of Earth's gravity.
Water can be found naturally in its solid, liquid and gas forms.
Water can be found in the outermost layers of the atmosphere, all the way down to the planet's core.
Timed test hurry!!
Answer:Water is unusual in that it can occur naturally in three distinct forms – gas, liquid and solid – at the same time. ... And if you look up, you see evidence for water vapor, water's gaseous form, in the clouds floating in the sky. Most substances contract as they freeze, but water expands.
Explanation:
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.

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.
