chemistry of life
These are the Monomers of nucleic acids, Such as DNA and RNA.
What are nucleotides?
Molecules only diffuse through the semipermeable membrane of the cell if they have these two properties.
What are small and non polar?
Enzymes function in cellular reactions by lowering this.
What is activation energy?
This is the term for a change in the genetic makeup of a population over successive generations.
What is evolution?
This is the group in an experiment that does not receive the treatment or variable being tested, allowing for a comparison with the experimental group
What is the control group?
Many of the properties of water (adhesion, cohesion, surface tension , high specific heat, etc.) are a result by its ability to form these bonds with each other.
What are Hydrogen bond?
In order for cells to efficiently exchange materials with their surrounding, they contain highly folded membranes that increase this in the cell.
This type of energy is stored in an object due to its position or state, such as a rock at the top of a hill.
What is potential energy?
These are small random changes in the DNA sequence that can introduce new genetic variations into a population, and they are the ultimate source of all genetic diversity?
What are mutations?
This type of variable is the factor that is deliberately changed or manipulated in and experiment to test its effect.
what is independent variable.
polymers are broken apart using this process, which involves the addition of water to break covalent bonds.
What is hydrolysis?
In areas of cells with high concentration of nonpermeable solutes, differences in free water potential cause water to do this.
What is diffuse into the cell?
As a roller coaster reaches its highest point of its track, its potential energy is at its maximum. As it descends, its potential energy is converted into this type of energy.
This concept is known as "survival of the fittest," describes how individuals with traits better suited to their environment are more likely to survive and reproduce, passing on those traits to future generations.
What is natural selection?
This type of data involves numerical values and can be measured and analyzed statistically. It includes things like height, weight, temperature, or time.
what is quantitative data?
Altering the PH, temperature or salinity of an enzyme my change its structure and in turn its function due to the differences in the characteristics and interactions of these.
R groups
The NaCl concentration of red blood cells is 154mM. Predict what would happen if the cell was placed in a 220 mM NaCl solution.
What is the cell would shrivel?
This part of the enzyme, often referred to as the "pocket," is where the substrate binds and the chemical reaction takes place.
What is the active site?
This principle, proposed by Hardy and Weinberg, states that the allele frequencies in a population will remain constant from generation to generation in the absence of evolutionary forces.
What is the Hardy-Weinberg equilibrium.
This statistical measure calculates the central tendency of a data set and is the sum of all values divided by the number of values.
What is mean or average?
Lipids different from the other 3 classes of macromolecules in that they have this property such as in the tails of phospholipids.
What is nonpolar?
The rough ER and smooth ER are similarly folded membranes. The rough ER is studded with ribosomes for protein synthesi, while the smooth ER's function is to detoxify and synthesize these.
What are lipids?
This type of inhibitor binds to the enzyme at a site other than the active site, causing a change in enzyme shape and reducing its activity.
What is a non-competitive inhibitor?
Tapeworms are segmented flatworms that attach themselves to the insides of the intestines of animals such as cows, pigs, and humans. They get food by eating the host's partly digested food, depriving the host of nutrients. This is an example of what symbiotic relationship?
What is parasitism?
Find the average of this data set:
10, 15, 25, 25, 10
What is 17?
