how does the plasma membrane contribute to the structure and function of the cell?

Answers

Answer:

The plasma membrane, also called the cell membrane, is the membrane found in all cells that separates the interior of the cell from the outside environment. ... The plasma membrane consists of a lipid bilayer that is semipermeable. The plasma membrane regulates the transport of materials entering and exiting the cell.

A cell is protected by its cell membrane, also known as the plasma membrane. Additionally, it moves hazardous materials out of the cell and carries nutrients into the cell.

What is a cell membrane?

All cells' interiors are protected from the outside world by a biological membrane called the cell membrane. A cell is protected by its cell membrane, also known as the plasma membrane. Additionally, it maintains a constant environment inside the cell, and that membrane serves a variety of purposes. One is to move substances out of the cell that are toxic as well as nutrients into the cell.

Glycerophospholipids, molecules made of glycerol, a phosphate group, and two fatty acid chains, are what make up cellular membranes, including plasma membranes and internal membranes.

Answers

Answer:

(Hope this helps can I pls have brainlist (crown)☺️)

Explanation:

They consume food and they have much higher metabolism. That means that more waste products are produced. Plants can use much of the waste produced and it is in fact raw material. Animals don't normally produce their own chemicals from scratch like plants normally do so they can't just recycle the waste. They need to remove it. About the only waste plants need to get rid of is excess oxygen produced during the day. That is actually three reasons but recycling is related to plants not consuming but making their own chemicals from scratch. In a way it pretty much comes down to one main reason.

B. nucleus
C. flagella
D. cell wall

Answers

The answer is D, A, C

Nucleus is an exception in a prokaryotic cell. Thus, option A, C and D are correct.

What are the characteristics of a prokaryotes?

Prokaryotes are microscopic and primitive cells. Their nucleus is not well developed.

Prokaryotes lack cell organelles like mitochondria, endoplasmic reticulum, Golgi body etc in their cell structure.

Prokaryotes are simple in assembly and are therefore unicellular. A single cell performs all the functions in the body.

Prokaryotes have single chromosome present in their structure. Their DNA is found in the cytoplasm.

Prokaryotes have cilia and flagella for locomotion.

Prokaryotic organisms are found extensively everywhere on earth. They have unique ability to survive in the harsh environments.

Prokaryotes are beneficial in many ways:

Carry out nitrogen fixation.Important for human gut for the absorption of vitamin B12.Helpful in fermentation process.Important in bioremediation

Answer:

molecules that combine to form proteins

Explanation:

amino acids are molecules that combine to form proteins. amino acids and proteins are the building blocks of life. when proteins are digested or broken down amino acids are left

Amino acids are building blocks of proteins. They contain an amino group, carboxyl group, and side chain. There are 20 types, each with unique properties influencing protein structure and function.

Biochemical functions depend on amino acids in proteins. The R-group, amino group, and carboxyl group are on each amino acid. This side chain gives each amino acid chemical properties that impact protein structure and function. Twenty typical amino acids make up proteins.

They vary in size, shape, charge, and hydrophobicity. Peptide bonds generate polypeptide chains that fold into three-dimensional forms, determining a protein's function. The structures include simple helices and complex globular shapes. Complex and diverse, proteins perform various tasks in living things due to the diversity of amino acids and their interactions.

Answer:

Explain how kinetic energy affects each object as it changes its state of matter:

A) Water boiling:

B) Popsicle freezing:

C) Water condensing on the side of a water bottle:

Explanation:

A) A water boiling will result in evaporation, therefore the particles will move extensively faster than liquid due to it being vapor.

B) A popsicle freezing is originally a solid so it'll have the least amount of kinetic energy as the particles remain fairly slow.

C) Due to the fact that water is condensing, while turning into a liquid. The water condensing on the side of the water bottle would produce a lower kinetic energy level due to the fact that it's becoming a liquid. Though liquids have higher kinetic energy than solids, as gases have a higher kinetic energy compared to liquids.

Evaporation from boiling water causes the particles to move much more quickly than they would in a liquid state.

What is Kinetic energy?

A popsicle is initially a solid, it will have the least kinetic energy because the particles are still moving slowly.  Because water is condensing as it transforms into a liquid.

Because it is turning into a liquid, the water that is condensing on the water bottle's side would have less kinetic energy.

Gases have a higher kinetic energy than liquids, despite the fact that liquids have a higher kinetic energy than solids.

Therefore, Evaporation from boiling water causes the particles to move much more quickly than they would in a liquid state.

In eukaryotes, gene expression is regulated mostly by _____.

Answers

Answer:

Gene expression in eukaryotic cells is regulated by repressors as well as by transcriptional activators. Like their prokaryotic counterparts, eukaryotic repressors bind to specific DNA sequences and inhibit transcription.

Explanation:

In eukaryotes, gene expression is regulated mostly by transcription factors.

What are transcription factors?

Transcription factors are proteins that bind to DNA in the promoter region of a gene, and they play a critical role in controlling when and to what extent a gene is expressed.

They can either activate or repress gene expression by promoting or inhibiting the recruitment of RNA polymerase. Transcription factors are themselves regulated by a variety of signals, including hormones, growth factors, and other external cues, as well as by feedback loops and other regulatory mechanisms within the cell.

Ultimately, this complex interplay of factors allows eukaryotic cells to precisely control which genes are expressed, when they are expressed, and to what degree, enabling them to respond to changing internal and external environments.

Glucose has combined with oxygen to make carbon dioxide.
Glucose has 6 carbons and has been completely broken down by this stage.

Glucose has combined with oxygen to make carbon dioxide and Glucose has 6 carbons and has been completely broken down by this stage.

Glucose react with oxygen to make carbon dioxide, water and energy in the form of ATP.  Glucose has 6 carbon atoms which react with oxygen that is  completely broken down into three products such as carbondioxide, water and energy in the form of ATP by the process of cellular respiration so we can conclude that carbondioxide gas is produced by breaking down of glucose molecules from the Krebs cycle that is a stage of respiration.
