How can the reliability of the investigation be improved?
Answer:
You can test reliability through repetition. The more similar repeated measurements are, the more reliable the results. The reliability of single measurements is not improved through repetition, but through the design of the experiment. Implementing a method that reduces random errors will improve reliability.

two glass tubes are placed in water one of them has very concentrated sucrose solution while the other has a concentrated sucrose solution after an hour what will happen to the liquid levels in the glass
Answer:
The liquid levels in the solution will become more dilute (have more water) due to Osmosis.
Explanation:
This is because Osmosis moves down a concentration gradient so the water outside the solution will become more concentrated and the solution will become more dilute.

explain the relationship between stem cells and gene expression
Explanation:
This process your body uses to turn genes on and off is the same one it uses to develop from one cell into the many different cell types that make up your body. Stem cells have the ability to turn into any other type of cell in the body, an ability known as pluripotency.
The relationship between stem cells and gene expression is the process by which the body uses to turn genes on and off is the same one it uses to develop from one cell into the many different cell types that make up your body. Stem cells have the ability to turn into any other type of cell in the body, an ability known as pluripotency.
What is stem cell?Stem cell has been defined as the cell and the raw material of the body and these are the cells which has been specialized the function has been generated. In the right condition of the body or the laboratory, the stem cells has been divided to form the cells known as the daughter cell.
Daughter cell is known as daughter cell because they have to divide again the this quality of division is just the character of daughter cell. Stem cells have the ability to turn into any other type of cell in the body, an ability known as pluripotency.
Therefore, The relationship between stem cells and gene expression is the process by which the body uses to turn genes on and off is the same one it uses to develop from one cell into the many different cell types that make up your body.

. B.9(C) For an enzyme to be able to catalyze a reaction, the active site must---- *
1 point
be occupied by an inhibitor
increase the activation energy level
have a complementary shape to the substrate
cause the enzyme to be destroyed in the reaction
go keilani
A protein that speeds up a biological and chemical reaction to build and split any molecule is called an enzyme. They are produced naturally in the body.
The correct answer is:
Option C. have a complementary shape to the substrate.
This can be explained as:
If the active site on the enzyme is occupied by an inhibitor then the substrate will not be able to bind and the reaction will not occur.Activation energy is the minimum amount of energy needed for the reaction.If the enzyme is destroyed then no reaction will occur as the active site is present on the enzyme surfaces.Therefore, the active site should have a complementary shape to the substrate.

before running the gel, dna is mixed with dye and loaded into _______ by the use of a pipette.
Before running the gel, DNA is mixed with dye and loaded into wells through the use of a pipette.
What is Gel electrophoresis?Gel electrophoresis may be defined as a type of laboratory methodology that is significantly utilized in order to separate mixtures of DNA, RNA, or proteins according to molecular size. This process is used to analyze the biomacromolecules and their fragments on the basis of their charge and size.
In this technique, the molecules that have to be separated are pushed by an electrical field through a gel that contains small pores. Before performing an actual mechanism, DNA is mixed with a dye known as Ethidium bromide and then loaded into wells which are formed by Acrylamide gel through the use of a pipette.
Therefore, before running the gel, DNA is mixed with dye and loaded into wells through the use of a pipette.

if a bacterial cell is capable of taking up foreign dna, it is said to be what?
Answer:
competent
Explanation:
The uptake of foreign DNA from the environment is known as transformation
If a bacterial cell is capable of taking up foreign DNA, it is said to be competent.
What is competent?
Transformation is the process by which bacteria can absorb foreign DNA. In DNA cloning, transformation is a crucial step. After restriction digest and ligation, it takes place and transmits freshly created plasmids to bacteria.
Bacteria are chosen on antibiotic plates after transformation. Bacteria are extraordinarily adaptable creatures, with the rare capacity to take in and replicate (or copy) foreign DNA.
They gain an evolutionary advantage from this and are better able to withstand environmental changes. Bacteria, for instance, can acquire DNA that renders them immune to antibiotics.
Therefore, the term is competent for a bacterium that is capable of taking up foreign DNA.
