The resting potential of a resting neuron is caused by
Answer:
A resting (non-signaling) neuron has a voltage across its membrane called the resting membrane potential, or simply the resting potential. The resting potential is determined by concentration gradients of ions across the membrane and by membrane permeability to each type of ion.
Explanation:
hopefully that helps?
The resting potential of a resting neuron is caused by the differences in ion concentration of the intracellular and extracellular fluids and the relative permeabilities of the plasma membrane to different ion species.
What is neuron?Neurons also known as nerve cells are the basic components of the brain and nervous system.
They are the cells that receive sensory information from the outside world, give motor orders to our muscles, and convert and relay electrical impulses at every step along the way.
What is resting potential of neuron?The electrical charge imbalance that exists between the inside of electrically excitable neurons (nerve cells) and their surroundings is known as resting potential.When a cell is not stimulated, its resting membrane potential is defined as the electrical potential difference across the plasma membrane. The electrical potential differential across a cell membrane has traditionally been represented in terms of its value inside the cell compared to the extracellular environment.The K+ that leaks from the interior of the cell to the outside via leak K+ channels creates a negative charge on the inside of the membrane compared to the outside, resulting in the resting membrane potential. Because all of the Na+ channels are closed at rest, the membrane is impermeable to Na+.To know more resting potential of neuron here

Match the given behaviors of water with their correct rationale. Use your observations about water and the reading you have done to draw conclusions about these behaviors. Drag the items on the left to the correct location on the right. Correct high specific heat Correct ice floats on water Correct cohesion Correct high heat of vaporization Hydrogen bonds between water molecules keep the molecules "sticking together." Heat energy first breaks hydrogen bonds before it increases movement of water molecules. As a result more heat is required to raise the temperature of water. A large amount of energy is needed to convert liquid water, where the molecules are tied by hydrogen bonds, to water vapor, where they are not. As water freezes, the hydrogen bonds form a crystalline lattice which keeps the molecules at a consistent distance leading to a density lesser than liquid water.
Answer:
Heat energy first breaks hydrogen bonds before it increases movement of water molecules - High specific heat
As water freezes, the hydrogen bonds form a crystalline lattice which keeps the molecules at a consistent distance leading to a density lesser than liquid water- Ice floats on water
A large amount of energy is needed to convert liquid water, where the molecules are tied by hydrogen bonds, to water vapor, where they are not - High heat of vaporization
Hydrogen bonds between water molecules keep the molecules "sticking together." - Cohesion
Explanation:
Water is a molecule composed of two atoms of hydrogen and one atom of oxygen. Water is a very unique substance with properties that are unexpected of a molecule its size. Some of the unique properties of water include:
Its high polar nature, High-specific heat, High heat of vaporization, the lower density of ice. One of the reason for these unique properties is strong cohesive forces between water molecules.
Cohesion: Hydrogen bonds between water molecules keep the molecules "sticking together."
Polarity: Water molecules are polar, with partial positive charges on the hydrogens, a partial negative charge on the oxygen because oxygen is more electronegative than hydrogen. As a result, water is a good polar solvent.
High specific heat: Heat energy first breaks hydrogen bonds before it increases movement of water molecules.
Lower density of ice: As water freezes, the hydrogen bonds form a crystalline lattice which keeps the molecules at a consistent distance leading to a density lesser than liquid water, therefore, ice floats on water
High heat of vaporization: A large amount of energy is needed to convert liquid water, where the molecules are tied by hydrogen bonds, to water vapor, where they are not.

There may be a large number of people in the area where people want to mine. There will be many deaths if there are many people and there is an explosion in the mine.
What is mining?Mining is the extraction of useful materials from the earth. Coal, gold, and iron ore are some examples of mined materials. Iron ore is the raw material used to make the metal iron.
Mine exploration, construction, operation, and maintenance may result in land-use change and have negative environmental consequences such as deforestation, deterioration, contamination.
Also, the modification of soil profiles, contamination of local streams and waterways, and an increase in noise and dust.
There could be a large population in the area where people want to mine. If there are a lot of people and there is an explosion in the mine, there will be a lot of deaths.
Thus, this way, effects on society can impact the decision of whether to mine for resources in certain areas.

Gametes must be haploid because
two gametes will unite during fertilization to create a diploid cell
fertilization results with a haploid zygote
gametes are small and can hold only the haploid number of chromosomes
the gametes' chromosomes will be replicated prior to cell division
Due to the fact that two gametes (one from each parent) unite during fertilization to form a diploid zygote, gametes must be haploid, meaning they contain half as many chromosomes as somatic cells of an organism. Therefore, the correct option is A.
When gametes fuse, a diploid cell with a full set of chromosomes is produced, which combines their haploid sets of chromosomes. After cell division and growth, this diploid zygote will form a new human with a full complement of chromosomes in each cell. To preserve proper ploidy during fertilization and subsequent development, gametes must be haploid.
Therefore, the correct option is A.

DNA is considered the blueprint of life, yet in eukaryotic organisms, such as humans, DNA never leaves the nucleus. Which of the following is the best explanation for how DNA codes into physical traits and characteristics, even though it never enters the cytoplasm?
Answer:
There are no options to this question, however, it can be answered. The answer is:
DNA is transcribed into MRNA, which is translated into proteins responsible for physical traits and characteristics.
Explanation:
DNA is the genetic material of living organisms. As stated in this question, DNA is considered the blueprint of life. However, this DNA is permanently located in the nucleus of eukaryotic cells. The information in this DNA is used to synthesize a mRNA molecule in a process called TRANSCRIPTION.
This mRNA molecule then transports the genetic information from the nucleus to the cytoplasm (specifically the ribosomes) where the process of TRANSLATION i.e. synthesis of protein from mRNA, occurs. The produced proteins are responsible for the physical traits and characteristics.
Hence, the DNA never leaves the nucleus but it transfers it's stored genetic information to mRNA and subsequently proteins.
