Enzymes, such as the one shown in the picture, work by fitting onto the substrate molecule like a lock-and-key action. Which statement is true, with regard to the enzyme and the substrate?

Answers

Answer 1
Answer:

Answer;

A)  The enzyme weakens chemical bonds in the substrate and catalyzes a change into the product. The enzyme itself remains unchanged.

Explanation;

  • Enzymes are biological catalysts that speed up chemical reactions. Enzymes catalyze or speed up a reaction by binding to a substrate using its active site.
  • The active site of an enzyme is suited to bind a particular substrate, that is why enzymes are known to substrate specific.
  • The binding of the substrate to the enzyme results to changes in the distribution of electrons in the chemical bonds of the substrate and consequently leads to  reactions that lead to the formation of products.
Answer 2
Answer: The enzyme weakens chemical bonds in the substrate and catalyzes a change into the product. The enzyme itself remains unchanged.

     In a stringed musical instrument, the part that vibrates in resonance with the sound waves produced by the strings is called the sounding board. Hope this helped ;)

The answer is C. The sounding board.

A is a cell that points to b. b is tissue that points to c. c is an organ system that points to an organ. sunny makes a poster showing the levels of organization in the human body. how can sunny correct his error? check all that apply. arrow a should point to the organ system. arrow b should point to the cell. arrow b should point to the organ. arrow c should point to the muscle tissue. arrow c should point to the organ system.

Answers

Sunny's poster has a couple of errors in the direction of the arrows. The correct directions of the arrows should be:

  • Arrow A should point to the tissue (not the organ system).
  • Arrow B should point to the organ (not the cell).
  • Arrow C should point to the organ system (not the muscle tissue).

The correct order of the levels of organization in the human body is:

  • Cells
  • Tissues
  • Organs
  • Organ systems
  • Organism

Therefore, arrow A should point to the tissue (a group of cells that perform a specific function), arrow B should point to the organ (a structure made up of tissues that work together to perform a specific function), and arrow C should point to the organ system (a group of organs that work together to perform a specific function). By correcting the directions of the arrows, Sunny's poster will accurately represent the levels of organization in the human body.

Three critical things that genes were known to do

Answers

Three critical things of genes are it carry all the genetic  information from one generation to the next generation, it determine heritable characteristics of organisms, it is easily copied.

what are the characteristic feature of a gene ?

Gene is located within the chromosome and it is an inseparable part of a chromosome, consists of Nucleic acid that is mainly DNA.

A gene consist of  1500 nucleotides and the chemical structure of one gene does not influence on the chemical structure of other chromosomes

Number of genes is uncountable, the genes of a particular chromosome are arranged by a specific method and the place where is located called as   locus

The volume of a gene may be about 1.20ยต, capable of self-replicating without any change of characteristics where the new generation inherits the characteristics from their parents due to the transfer of genes.

Differentiate between plant cell and animal cell prokaryotic cell eukaryotic cell

Answers

There are differences between Eukaryotic and Prokaryotic cells. A Prokaryotic cell does not contain a nucleus. It only contains one chromosome and is a single-celled organism. It was the only form of life on earth for millions of years. Examples of a Prokaryotic cell are the different types of bacteria present today. 
A Eukaryotic cell contains a nucleus; more than one chromosome and is typically a multicelled organism.  Both plant and animal cells are eukaryotic cells, but there are differences between the two. A plant cell has a cell wall while an animal cell does not have a cell wall. A plant cell is a regular shape and an animal cell is an irregular shape. Both plant and animal cells have a nucleus. There are just a few examples of the differences between Eukaryotic and Prokaryotic cells.
