Whats the purpose of the process for us humans of cellular respiration
Answers
The purpose of the process of cellular respiration is to get energy from the food.
Cellular Respiration is the process of extracting energy in the form of ATP from the glucose present in the food we eat. It is a three-step process:
In stage one, glucose is broken down in the cytoplasm of the cell in a process called glycolysis.in stage two, the pyruvate molecules are transported into the mitochondria.In stage three, the energy in the energy carriers enters an electron transport chain. During this stage, the energy is used to produce ATP.Oxygen is needed to help the process of turning glucose into ATP. The initial step releases just two molecules of ATP for each glucose. The later steps release much more ATP.

Let as assume these genes express complete dominance and do not interact.
We will name
T the dominant allele that codes for thick eyebrowst to the recessive allele that codes for narrow eyebrowsS the dominant allele that codes for separated eyebrowss the recessive allele that codes for joined eyebrows.Let us see the genotypes of alexia and michael.
Michael genotype
He is unibrow so his genotype for this trait is ss, h0m0zyg0us recessive.He has a thick eyebrow so he can be either TT or Tt. Since his mother has narrow eyebrow, she is h0m0zyg0us recessive for this trait. Then Michael must have inherited the recessive allele from her, which means that Michael is heter0zyg0us for the trait, Tt.
Michael's genotype is Tt ss
Alexias genotype
She has narrow eyebrows, so her genotype for this traits is h0m0zyg0us recessive, tt. She has separated eyebrows, which means she can be either SS or Ss. Since her father has unibrow (ss) she must have inherited the recessive allele from him. Then Alexia is heter0zyg0us for the trait.
Alexia's genotype is tt Ss
Now let us perform the cross.

xylem transports water to various parts of the plant
cuticle is a thin waxy and transparent layer.it is shiny to reduce excessive loss of water and it is transparent to allow light to penetrate through

why does the Idli batter rise in a few horse when small amount of eastern sugar is added to it?
Answers
Adding a small amount of Eastern sugar (also known as Eno or fruit salt) to Idli batter causes the batter to rise in just a few hours due to a chemical reaction.
Eastern sugar is a combination of sodium bicarbonate and citric acid, and when it is added to the batter, the acid and the bicarbonate react to produce carbon dioxide gas. This gas gets trapped in the batter, causing it to rise and become light and fluffy. This process is similar to the one that occurs when baking soda and vinegar are mixed, which also produces carbon dioxide gas. Eastern sugar is commonly used as a leavening agent in many Indian dishes and is especially popular for making Idlis and Dhoklas.

Answers
The twisting of the parental DNA strand around each other ahead of a replication fork is called DNA supercoiling.
Supercoiling is a natural process that occurs during DNA replication and transcription. As the DNA strands unwind to allow for the synthesis of new strands, the region ahead of the replication fork becomes overwound. To relieve this strain, the DNA molecules twist around each other in a coiled fashion. This supercoiling helps to maintain the integrity and stability of the DNA structure during replication and ensures the proper functioning of enzymes involved in DNA replication and transcription.

Which of the following does NOT serve as a signal for cell division?
a-Shrinkage in the surface-to-volume ratio.
b-Loss of contact inhibition.
c-Joining of cyclins and Cdks.
d-Repressor genes.
Answers
The repressor genes do not serve as a signal for cell division. Here option D is the correct answer.
Cell division is the process of dividing one cell into two identical or nearly identical daughter cells. It is a fundamental process that occurs in all living organisms to maintain the continuity of life. Cell division plays an essential role in growth and development, tissue repair, and the production of new cells for reproduction.
Several signals regulate the cell cycle and control cell division. The signals can be internal or external, and they ensure that the cells divide accurately and efficiently. Some of the important signals for cell division are Growth factors: These are external signals that stimulate cell growth and division.
Cell adhesion molecules: These are proteins that regulate the attachment of cells to each other and the extracellular matrix. Cell cycle checkpoints: These are internal signals that regulate the progression of the cell cycle and ensure that the cell is ready for the next phase.
Cyclins and cyclin-dependent kinases: These are internal signals that control the progression of the cell cycle. Repressor genes: These are internal signals that inhibit cell division. Therefore option D is the correct answer.

A channel protein, but not a carrier protein, can exist in a open configuration creating a pore through a membrane. True or false?.
Answers
True. On one side of the membrane, carrier proteins bind to molecules or ions and release them on the opposite side.
Channel proteins are found in membranes surrounding cells or organelles. Cells use many different molecules that need to cross the membrane for internal use or be exported to the extracellular space. Some small, non-polar molecules can cross membranes directly, whereas larger or charged molecules must use specialized proteins or endo/exocytosis to enter and exit.
Channel proteins allow these molecules to enter and exit cells, usually without expending energy. Examples include aquaporins, which allow polar water molecules to penetrate. Another example plays an important role in cell communication. Ligand-gated ion channel. In order for these channel proteins to open, they need a binding ligand (ligands are molecules that act as the "key" for the channel protein). The presence of a ligand signals the protein to open, making it easier for molecules to pass through.

Answers
Blocking ribosomes prevents protein assembly. The correct answer to the question is option d) protein assembly.
Blocking ribosomes can prevent protein assembly, which is the process of assembling amino acids to form proteins. Ribosomes are the primary site of protein synthesis in a cell, and they play a crucial role in the formation of peptide bonds between amino acids. By blocking ribosomes, the formation of peptide bonds is impeded, which can lead to the inhibition of protein assembly.
This can occur due to several factors such as the presence of an antibiotic that prevents the functioning of ribosomes, or the genetic modification of the ribosome, which changes the way it interacts with amino acids. Blocking ribosomes can have significant consequences on the cell's ability to carry out its normal functions, as proteins are essential for the proper functioning of all living organisms.

As the mRNA strand is read, another molecule carries the necessary amino acid to the growing amino acid chain.
What is the name of this transporting molecule?
What type of bonds hold together the amino acids?
Answers
The transporting molecule that carries amino acids to the growing amino acid chain during protein synthesis is called transfer RNA (tRNA). The amino acids are held together by peptide bonds.
A particular amino acid is transported to the ribosome by transfer RNA (tRNA), a type of RNA molecule, during the proteinsynthesis process. Each tRNA molecule has an anticodon, which is a specific three nucleotide sequence that is complementary to a particular codon on the mRNA strand.
This enables the delivery of the proper amino acid to the lengthening amino acid chain by allowing the tRNA molecule to recognize and bind to the proper codon on the mRNA.
Peptide bonds, which hold the amino acids in the growing chain together, are created when the carboxyl group of one amino acid and the amino group of another amino acid combine.

Yeast is a microorganism that is commonly used in the process of making beer. When yeast ferments glucose during beer production, it generates ATP molecules as an energy source. Under ideal conditions, one molecule of glucose can produce 38 ATP molecules in yeast. Actually, yeast is a kind of fungus linked to mushrooms. Although there are more than 1,000 types of yeast, Saccharomyces cerevisiae is typically the one utilized for baking.
