Answer:
1. Cell differentiation
2. Fermentation
3. Yeast
4. D option
5. Oxygen
6. All living organisms carry some sort of cellular respiration
7. Mitochondria

What are cells?
Cells are basic unit of life. The cell which is responsible for the development of an organism is zygote. The zygote undergoes cell differentiation to develop various body parts and the whole organism.
If the test tubes were allowed to stand at room temperature for several hours, this process is called fermentation. In this process, anaerobic respiration takes place. Organisms that may make use of anaerobic respiration includes yeast.
The process of cellular respiration includes all of these processes such as glycolysis, fermentation, and electron transport chain.
During the process of photosynthesis, oxygen gas is released as a product with the formation of glucose which is utilized in respiration.
The process of cellular respiration is an important biochemical reaction which takes place in all forms of living organisms. During this process, glucose is oxidized to form energy in the form of ATP.
The process of cellular respiration takes place in the mitochondria of cells. Mitochondria is known as the powerhouse of cell as it produces ATP.
38 molecules of ATP are produced by the process of cellular respiration in the mitochondria of cell. These ATP are utilized in various biochemical reactions.
Orange-red and violet-blue regions of the spectrum are indicated in the given image which shows the energy used in the photosynthesis. These are the most active regions of light spectrum.

6. What is the benefit of a scientific name vs. a common
name
Answer:
We use scientific names because it gives us a good way to organize species and name them.
Explanation:
In contrast to common names, a scientific name is the same in all languages and gives an entity a distinctive name, making it possible for two individuals to be certain that they are speaking about the same thing.
What is a scientific name?A common and official way to name species is using binomial nomenclature. Two names that are both borrowed from Latin make up the nomenclature.
But it can also be derived from other tongues. This kind of name is sometimes referred to as a binomial name or a scientific name.
A formal way of identifying species of living things by assigning each one a name made up of two components is known as binomial nomenclature, also known as binominal nomenclature or binary nomenclature in taxonomy.
Therefore, a scientific name is the same in all languages and gives an entity a distinctive name.

Inside the cell is 40% helium and outside the cell is 20% helium. Which of
the following will occur? *
A. helium will move out of the cell
B. helium will move into the cell
C.helium will not move
Answer:
A. Helium will move out of the cell
Inside the cell the concentration is higher than concentration off outer cell so the inner helium well more about of cell
Answer:
[tex]\boxed {\boxed {\sf A. \ Helium \ will \ move \ out \ of \ the \ cell}}[/tex]
Explanation:
Diffusion is the movement of particles from a high concentration to a low concentration. This is the process occurring in this question.
In this cell, 40% helium is inside the cell.
20% is outside of the cell.
40 is greater than 20. Therefore, the helium wants to move from the area of 40% to 20%, which is also from the inside of the cell to the outside. Basically, the helium moves out of the cell.
So, the best answer is choice A: helium will move out of the cell.
order of events when a volcano erupts
Answer:
Earthquakes, gas emissions, ash/steam venting, lava buildup, dome collapse, explosion, eruption.
Explanation:
1 Earthquakes - swarms of earthquakes happen first.
2 Gas Emissions - gas begins to emit from the volcano.
3 Ash/steam venting - ash and steam begin to fill the air.
4 Lava Dome Buildup - lava builds up, getting closer to the dome of the volcano.
5 Dome Collapse - the dome collapses, leaving the lava free to burst out.
6 Magmatic Explosion - magma begins to escape from the volcano.
7 Pyroclastic Eruption - finally, the volcano erupts.
Read the sentence. The famous physicist who discovered the element received much acclaim and many prestigious awards. The underlined phrase is a(n) phrase.
Answer:
The underlined phrase is a verb phrase. This is the case because the head of the phrase is the transitive verb to receive which, in this case, is in the past simple form.
The transitive verb in question, as I have said, is a transitive verb which takes two arguments: the NP "the famous physicist who discovered the element" and the NP "much acclaim and many prestigous awards".
Explanation:
The underlined phrase, "who discovered the element," is a relative clause.
What are Clauses?A clause is a group of words that includes a subject, a predicate, and perhaps a verb. Clauses can be used as complete sentences or as fragments of sentences. Usually, one or more clauses are linked in different ways to form a sentence.
Independent and dependent clauses are the two primary categories of clauses. A dependent clause cannot be a sentence by itself, whereas an independent clause can be. Subordinate clauses, also known as dependent clauses, sometimes begin with a subordinating conjunction or a relative pronoun. "Who discovered the element" (underlined) is a relative clause modifying "the famous physicist".
Therefore, the underlined phrase, "who discovered the element," is a relative clause.

Only in the winter when food and shelter are more scarce.
Yes, all the populations in a community effect each other.
Answer:
I would say yes, all the populations in a community affect each other.
Explanation:
In biology, the concept of carrying capacity pertains to the number of organisms that can survive in a certain environment based upon their resources. So, if the species relies on the other species that live within the same environment, it would obviously affect that species.

The learning process that occurs when the same response happens in reaction to many similar stimuli is option D: generalization.
Why is generalization important in learning?It is significant because it enhances the possibility that the learner will be successful in completing a task without the help of a specific teacher or resources that are only available in one instructional environment. The value of skill generalization is frequently undervalued.

The diagram below is a model of the process of transcription.
What is the purpose of strand B?
a) To act as a template for the synthesis of messenger RNA
b) To carry the code from the DNA molecule in the nucleus to the ribosome
c) Delivers specific amino acids to the ribosome to make proteins
d) Transfers nucleic acids to the nucleus
Answer:
b
Explanation:
The purpose of the strand B be would be to carry the code from the DNA molecule in the nucleus to the ribosome.
Looking closely at the diagram, strand B is the strand of RNA that is still in the process of being synthesized while strand A is acting as the template. The function of the RNA strand is primarily to carry an encoded message in the DNA molecule from the nucleus to the ribosome in the cytoplasm where the genetic codes would be translated during the process of protein synthesis.
The correct option is, therefore, b.
The purpose of strand B would be to carry the code from the DNA molecule in the nucleus to the ribosome (option b)
The strand B shown in the figure represent the RNA transcript derived from the transcription process due to the presence of uracil which is always found in RNAs.
After undergoing a series of processes including transcriptional control, they become mRNA and are transported to the ribosome to undergo translation to proteins.

O linked to other cells to form long chains of cells.
O floating around one another in a fluid structure.
O locked together in a rigid structure.

Answer:
O floating around one another in a fluid structure
Explanation:
Cells are made up of varying types of molecules in order to achieve a fluid, stable plasma membrane. The membrane mainly consists of:
lipids proteins cholesterolLipid membranes help maintain selective membrane permeability. The lipids, formed from glycerol and saturated/unsaturated fatty acids, are made up of polar heads and non-polar tails; they typically only allow the movement of small non-polar molecules. Larger molecules are transported through integral proteins; other types, are peripheral, and may have specialized functions like cell signaling.
Cholesterol molecules keep the lipids in place, and ensure membrane fluidity. In extreme temperatures, they help the membrane to maintain its shape without becoming too rigid.
