Answer:
c
Explanation:
When the membrane of the neuron is in a state of rest, the interior of the cell has a more negative charge in relation to the exterior, therefore option "c" is correct.
What is the membrane potential in a resting neuron?It is a phenomenon that occurs when the nerve cell membrane is not altered by action potentials.
Characteristics of a resting neuronThe resting potential is determined by the concentration gradients of the ions, both inside and outside the neuron, and by the permeability of the membrane.When a cell is at rest, the potassium channels are open, the potassium will tend to flow outwards (K ions), they are positive charges, therefore the cell interior will be negative with respect to the cell exterior.Therefore, we can conclude that the resting potential of a membrane occurs when they are not transmitting signals.

A student observes a reaction with an enzyme in a beaker. If nothing is removed from the beaker containing the reaction, what is the only thing the student must add to start the reaction again?
A.acids
B.enzymes
C.products
D.substrates
Answer:
90% Products, 10% Acids
Explanation:
enzymes are not consumed in a reaction. they remain mixed with reactants. if all products have reacted in the reaction and there's nothing left, the answer is products.
But acids promote chemical reactions at certain incidents. especially if it's an essential compound to the reaction.
Ex-: Sucrose is hydrolysed to Fructose and glucose by heating with an acid. but using sucrase, the same can be done.
approximately how many nucleosomes are required to organize this region of dna into the 10nm fiber structure?
Answer:
Answer is 512 nucleosomes.
Explanation:
DNA is the genetic material that is compressed and stored in the nucleus of the cell. Approximately 512 nucleosomes would be required to organize 92,672 base pairs long region.
What are nucleosomes?Nucleosomes are the packaging units of the genetic material that comprises the DNA segments wrapped along with the histone proteins in a compacted manner. This allows the genetic material to be condensed into smaller volumes.
Given,
Genome size = 92,672 base pairs
Linker DNA = 35 bp
The total number of base pairs = number of base pairs in nucleosome core + linker DNA
= 146 + 35
= 181
The number of nucleosomes can be calculated as:
Nucleosomes = Genome size ÷ total number of base pair
= 92,672 ÷ 181
= 512
Therefore, there are 512 nucleosomes are present in the Drosophila.

How does the hydrogen concentration of a solution change when the pH shifts from 6 to 2? (4 points)
Answer:
the overall concentration of hydrogen ions is universely related to its PH and can be measured on the physical (figure 1). therefore, the more hydrogen ions present.
The hydrogen ion concentration of a solution increases when pH shifts from 6 to 2.
What is pH?a metric for determining how basic or acidic a substance or solution is. The pH scale ranges from 0 to 14. A pH value of 7 is considered neutral on this scale, meaning it is neither acidic nor basic. It is more acidic if the pH value is below 7, and more basic if the pH value is above 7.
Typically, a pH meter is used to measure pH, which converts the difference in electromotive force (electrical potential or voltage) between suitable electrodes put in the solution under test into pH measurements.
The different solutions have different pH based on the concentration of hydrogen ions. The concentration of hydrogen ions increases when pH shifts from 6 to 2.

why does cell division occur in sexually reproducing organisms?
Answer:
to produce a complex multicellular individual
Explanation:
hope this helps
Cell division occurs in sexually reproducing organisms to maintain the organisms growth and development. Cells have a particular life cycle after which they die. These cells need to be replaced constantly.
What is Cell division?Cell division is the fundamental process to all living organisms and required for the growth and development of organisms. It is an essential means of reproduction for all the living things, cell division allows organisms to maintain their number and to transfer their genetic material to their offspring.
The role of this process in sexual reproduction is to produce sex cells (gametes) and to repair the genetic defects in germ line cells (sex cells). Both sexual and asexual organisms go through the process of mitosis. However, sexual reproduction also includes meiosis which maintains the number of chromosomes in off-springs.
