"D. The cell produces proteins specific to a particular cell type.
Explanation:
Differentiated cells are the cells that are bound to play out a particular capacity in the body i.e., they have turned out to be specific. These cells don't be able to change to play out another capacity. During cell separation, the phone experiences an adjustment in quality articulation. So as to play out its capacity, the cell produces explicit proteins. Case of a separated cell is the liver cell, platelet, and so on."
B) Different species share the same space.
C) A population is divided.
D) A major change on earth takes place.
2. Which of the following must be true of their individuals if two populations are no longer the same species?
A) They do not have any of the same genes.
B) They do not share any of the same space.
C) They do not resemble each other at all.
D) They cannot reproduce successfully with each other.
3. How does speciation start to take place on a genetic level between two isolated populations?
A) Large numbers of mutations occur.
B) Allele frequencies change in different ways.
C) New genes are added to one group.
D) Recessive alleles become dominant.
The 3rd question is actually B. Allele frequencies change in different ways
Answer:
Limestone is an example of biochemical sedimentary rock.
Explanation:
Sedimentary rocks are those that have been formed due to the accumulation of sediments over time from other rocks or organic remains. They correspond to 75% of the rocks in the world, being the most abundant.
Sedimentary rocks are generally classified, according to the way in which they are produced, in detritic or clastic, and chemical or non clastic; within the latter, there is a subcategory known as biochemistry.
Chemical sedimentary rocks are those that originate from materials deposited by chemical means, where the crystals are held together by chemical bonds or interwoven into each other. The materials, already dissolved, are transported and concentrated to form minerals that accumulate in aggregares and subsequently are lithified as in detritic rocks, to form a rock. Almost all of these rocks originate from chemical precipitation in extensions of surface water, either by inorganic chemical processes or by the chemical activity of organisms. Rocks formed by the activity of organisms are known as biochemical sedimentary rocks.
A clear example is limestone.
a type of minerals found inside of rocks

A decrease in the amount of air pollution
A cooling effect on Earth’s climate
2. Evaporation occurs when a ____ changes into a ____. *
Solid; liquid
Gas; liquid
Liquid; gas
Solid; gas
3. What is the definition of anaerobic? *
Producing oxygen
Producing methane
Containing bacteria
Lacking oxygen
4. What is the purpose of regularly mixing a compost pile? *
To decrease the temperature in the compost pile
To reduce the amount of oxygen in the compost pile
To prevent the production of methane in the compost pile
All of the above
Answer:
An increase in the amount of greenhouse gases in the atmosphere
Liquid; gas
Lacking oxygen
To decrease the temperature in the compost pile
Explanation:
1. Methane is one of the greenhouse gases. When these gases are released into the atmosphere, they increase the temperature of the earth surface because they trap heat within the earth. Other examples are carbon dioxide and water vapor.
2. Evaporation is a phase change from liquid to gas. During this process, heat is supplied to a liquid. When the molecules of the liquid gain enough energy, they then begin to break off into gaseous form. The reverse process of evaporation is condensation.
3. Anaerobic is a process that lacks oxygen. Aerobic processes are carried out with the availability of oxygen.
4. The reason why compost should be regularly mixed is to decrease the temperature in the compost pile. Portions of the compost can have a higher temperature than other parts. Therefore, mixing the compost will help to redistribute the heat in the compost.
