The nucleus is like the principal of a school, the cell membrane is like a school building, and the mitochondria is like the staff in a school.
Explanation:
Definitions:
The nucleus of a cell contains the majority of the cell's genetic material, and coordinates cell activities like protein synthesis and cell division.The cell membrane is the semipermeable membrane of a cell that surrounds the cytoplasm (the material inside the cell other than the nucleus).The mitochondria is "the powerhouse of the cell", because it produces most of the chemical energy needed to power the cell's chemical reactions.The nucleus is like the principal of a school: the nucleus controls the cell, much like how the principal controls the school.
The cell membrane is like a school building: the cell membrane forms a boundary between the cell and outside environment, much like how the school building separates you from outside.
The mitochondria is like the staff in a school: the mitochondria powers the cell, much like how the staff in a school keep the school running.

Which statement correctly distinguishes the functions of proteins from other types of biomolecules?
Answers
Answer:
This question is incomplete
Explanation:
This question is incomplete. However, the four major biomolecules have the following different functions
1) Nucleic acid (as in DNA and RNA): They are a sequence of nucleotides that store organism's genetic code. This nucleotide sequence in turn determines an organism's protein sequence.
2) Carbohydrates: They are important structural components of various "compositions" in an organism (such as the cellulose in cell wall and ribose in nucleotide). They also serve as energy sources for the body.
3) Lipids: They also serve as energy sources and are part of membrane composition (as in the case of the phospholipid cell membrane).
4) Proteins: They are major structural elements of cells. They serve as enzymes in many biological activity (such as hexokinase in glycolysis and DNA polymerase in DNA replication). They also form hormones (such as insulin) and antibodies (such as the Immunoglobulins).
Why do you think prokaryotic cells do not have all the organelles that eukaryotic cells do? What does this tell you about prokaryotic cells?
Answers
Answer:
Explanation:
A prokaryotic cell is a type of cell that does not have a true nucleus or membrane-bound organelles. Organisms within the domains Bacteria and Archaea are based on the prokaryotic cell, while all other forms of life are eukaryotic
A prokaryotic is a primitive cell that lacks organelles, unlike the eukaryotic cells, and are simple organisms.
What are prokaryotes?Prokaryotes are organisms that are simple and evolved before the complex eukaryote. They include bacteria and archaea that are simple and lack organelles that are found in eukaryotes.
They do not have a nucleus and rather have their genetic material disposed of as nucleoids in the center of the cell that undergoes the simple process of the central dogma.
The simple cellular processes and reproductive methods are the reason they lack many organelles. This tells that prokaryotes are simple and primitive types of cells.
Therefore, prokaryotes lack a distinct nucleus.

A cold front often brings intense weather changes such as thunderstorms while a warm front often brings light rain or drizzle. Why is this the case?
Answers
Answer:
The front term is associated with an area where two air masses met and as it is usually the condition with heavy rain, fierce wind, snow and other violent weather like a war situation. The front could be warm, cold, occluded or stationary depends on the type of weather.
The cold front is associated with lots of thunderstorms and other intense weather while the warm front changes with drizzly rain and warmer weather due to the fact that in a cold front, replacement of warm air by the cold air is faster while in a warm front, the replacement of cold air by warm air is gradual

b. To display self-peptides to demonstrate cell health
c. To display self-peptides to maintain self-tolerances
d. To display foreign peptides
e. All of the answers are correct.
Answers
Answer:
e. All of the answers are correct.
Explanation:
The major histocompatibility complex (MHC) is a locus that contains several polymorphic genes. These genes are known to encode different components of the immune system, especially cell-surface proteins which present antigens to the T cell receptors during adaptive immune responses. The MHC genes are classified into Class I, Class II and Class III:
1- MHC class I genes encode cell surface molecules that present peptides (antigens) to cytotoxic T lymphocytes (i.e., killer T cells)
2- MHC class II genes encode cell surface molecules that present antigens to CD4+ T cells
3- MHC class III genes encode proteins that are not involved in antigen presentation (i.e., components of the complement cascade, cytokines, etc)

c. Medication is needed to open channels to allow signaling molecules to enter pancreatic cells.
d. Medication is needed to serve as second messengers to regulate glucose uptake by cells.
Answers
Answer:
the answer is a. Medication is needed to act as a signaling molecule to activate the signal transduction pathway.
i took the quiz
Medication is needed to act as a signaling molecule to activate the signal transduction pathway. So, the correct option is (A).
What is Type 1 Diabetes?Type 1 diabetes also called insulin-dependent or juvenile diabetes which is usually develops in children, adolescents, and young adults, but it can occur at any age. A condition in which the immune system destroys the insulin-producing cells in the pancreas. These are called beta cells.
There are several signs of type 1 Diabetes which include:
Extreme thirstIncreased hungerDry mouthUpset stomach and vomitingFrequent urinationWhen a person suffering from this disease needs medication which is need to act as signaling molecule to activate the signal transduction pathway. Type 1 Diabetes is characterized by a progressive loss of insulin-producing β-cells in the islets of the pancreas. Immune destruction of β-cells is partly mediated by high levels of pro-inflammatory cytokines.
Thus, medication is needed to act as a signaling molecule to activate the signal transduction pathway. So, the correct option is (A).

What human activity provides a reasonable analogy for the movement of kinesin molecules along microtubules?a. running on a treadmill.b. climbing a rope hand over hand.c. shooting a fire hose at a beach ball.d. being one of many rowers in a boat .
Answers
Answer:
The correct answer is - option. b climbing a rope hand over hand is correct
Explanation:
The movement of the kinesin molecules led by the head of one kinesin followed by the second one after another same as one hand moves on the rope at a time and followed by the other hand during climbing the rope.
The movement of the kinesin microfilament is due to the increased affinity by ATP of the head of the kinesin for the microtubule. However, the hydrolysis of ATP decreases its affinity so it slides or moves to the plus end.
