Answer:
Iron and oxygen combining to make rust
Explanation:
A chemical reaction happens when one or more chemicals are changed into one or more other chemicals. Examples: iron and oxygen combining to make rust. vinegar and baking soda combining to make sodium acetate, carbon dioxide and water.
Jellyfish, they are consider the smartest and they have found things in them to help treat cancer.
The brain and spinal cord make up the central nervous system (CNS). It is one of the nervous system's two components. The peripheral nervous system, which consists of nerves linking the brain and spinal cord to the rest of the body, is the other component.
The body's processing center is the central nervous system. The majority of bodily processes, including awareness, movement, thought, speech, and the five senses of sight, hearing, feeling, tasting, and smelling, are controlled by the brain.
A brain extension is the spinal cord. It communicates with the brain by way of a network of peripheral nerves that are attached to it.
Therefore, Jellyfish, they are consider the smartest and they have found things in them to help treat cancer.

The woman with ptosis and her father have the genotype Pp, while her mother has pp. If she marries a man with normal eyelids (pp), there is a 50% chance that their children will inherit the dominant P allele and have ptosis.
The subject here is centered around genetics, specifically, a dominant genetic disorder called ptosis. The woman with ptosis would have a genotype of Pp, because she inherited one ptosis allele (P, for dominant) from her father and one normal allele (p, for recessive) from her mother. Hence, her father's genotype was also Pp, and her mother's was pp.
If the woman marries a man with normal eyelids (genotype pp), each child would have a 0.5 (or 50%) probability of inheriting the dominant P allele from the mother and thus, having ptosis. This is because each child will get a p allele from the father (since he can provide only that), and either a P or p allele from the mother with the probabilities being 50% for each. Hence, for these offspring, their potential genotypes can be Pp (ptosis) or pp (normal).

*prevent liquid from seeping between cells
Desmosomes
*act as rivets to hold adjacent cells together when epithelial tissue moves
Gap junctions
*allow movement of cytosol, ions, and small molecules between animal cells
Plasmodesmata
*openings through the cell walls of plant cells that allow adjacent cells to share materials
Answer:
Tight junctions - prevent liquid from seeping between cells
Desmosomes - act as rivets to hold adjacent cells together when epithelial tissue moves
Gap junctions - allow movement of cytosol, ions, and small molecules between animal cells
Plasmodesmata - openings through the cell walls of plant cells that allow adjacent cells to share materials
Explanation:
1) Tight junctions are one of the cell junctions found in animal cells. Tight junctions function to prevent the flow of liquid materials between cells.
2) Desmosomes are another type of cell junctions whose function is to form a connection between two adjacent cells. The structure formed by this connection confers strength upon the tissues involved.
3) Gap junctions are the most commonly found cell junctions found in animal cells that connects adjacent cells allowing the passage of cytosol, ions and other small molecules in them from one adjacent cell to another.
4) Plasmodesmata is a cell junction found in plant cells. They are small openings lying across the cell wall of plant cells whose function is to connect the cells and facilitate the movement of materials from one cell to another.
Tight junctions prevent liquid seepage between cells, desmosomes hold cells together, and gap junctions allow movement between animal cells.

B. Thiamine pyrophosphate
C. Biotin
D. FAD
Answer: Option B.
Thiamine pyrophosphate.
Explanation:
Pyruvate dehydrogenase is an enzyme that catalyses the oxidative decarboxylation of pyruvate to acetyl coA , NADH and CO2. Pyruvate dehydrogenase uses NAD, biotin, FAD and lipoic acid.
Thiamine pyrophosphate is not a cofactor for pyruvate dehydrogenase . It is a cofactor in living systems. Thiamine pyrophosphate is a coenzyme that function in carbohydrates, Amino acids and lipids metabolism.
Biotin is not a cofactor in the reaction catalyzed by pyruvate dehydrogenase. NAD+, Thiamine pyrophosphate, and FAD do function as cofactors in this reaction.
The cofactors used in the reaction catalyzed by pyruvate dehydrogenase are NAD+, Thiamine pyrophosphate, and FAD. The compound that is not used as a cofactor in this reaction is Biotin. Biotin functions as a cofactor for carboxylase enzymes, and it is involved in fatty acid synthesis and gluconeogenesis but not in the process involving pyruvate dehydrogenase.

b. RNA is removed from the sample by RNase treatment
c. detergent is used to break apart plant cells to extract DNA
d. lysozyme digest peptidoglycan in the bacterial cell wall
e. centrifugation separates cellular components based on size
Answer:
The correct answer is c. detergent is used to break apart plant cells to extract DNA.
Explanation:
Here we are talking about DNA isolation in E.coli and detergent is used to break apart the bacterial cell membrane by destabilizing the cell membrane. Detergent disintegrates the proteins present in the cell membrane which causes the rupture of membrane releasing the cell extract outside the cell.
Detergent is not able to break plant cell because it is made up of cellulose and require blending or mashing. Detergent can only be used to disintegrate the cell membrane because only cell membranes contain lipids and proteins.
Hence, the correct answer is c. detergent is used to break apart plant cells to extract DNA.

What are the different classes of protein ?
Protein is complex biomolecule made up of a multiple chain of amino acid formed by peptide bond which is a linear chain structure and it can be classified into two types such as complete and incomplete proteins.
Complete proteins contain all of the essential amino acids required for the body which include meat, fish, poultry, dairy, and soy products.
incomplete Foods where one or more essential amino acids are absent are called as incomplete proteins which include beans, grains, nuts, and vegetables.
it can be classified into five major Classes such as Enzymes, Structural Proteins, Transport Proteins, Regulatory Proteins and Hormones. where Enzyme catalyse the biochemical reactions in the body and Structural proteins provide support for cells and tissues.
