In a resting neuron, the area just inside of the cell membrane is more negative than the area just outside of the cell membrane.
A neuron is the nerve cell that functions to transmit signals to and from the brain. The structure of a nerve cell consists of a cell body surrounded by finger-like projections called dendrites. From one side of the body emerges the long axon, which ends at the axon terminal. The neuron is the longest cell in the body.
Cell membrane is the outer layer that surrounds the cell in living organisms. It is a semi-permeable membrane that allows the passage of limited substances through it. There is a potential difference between the two sides of the membrane due to difference in distribution of ions. The inner side is therefore more negative than the outer one.

how gender brains differ?
The main biological difference between the brain of women and men it's related to its volume. Since cis women gender (women who identify with the sex they were born with, i.e they have feminine reproductive organs ) is usually smaller than cis man gender ( men who identify with the sex they were born with, i.e masculine reproductive organs), usually their brain (women's) is also smaller than men. This difference of volume usually brings rigged other characteristics too, e.i smaller brains allow a slightly bigger proportion of grey matter compared to white matter, and more connection between both hemispheres (which is related to multitasking) compared with the connections inside each one of them.

Is the structure of DNA and replication of the DNA basically the same or basically different in bacteria and eukaryotes? Would a plant be able to replicate bacterial DNA that was inserted into the plant genome? Justify your answer.
The structure of DNA and the replication of DNA is fundamentally the same in both bacteria and eukaryotes. However, there are a few differences between the two that could result in significant variations. In both eukaryotes and bacteria, DNA replication begins at the origin of replication and proceeds in both directions.
DNA replication in eukaryotes, on the other hand, occurs in a compartment known as the nucleus, whereas DNA replication in bacteria occurs in the cytoplasm. Additionally, bacteria have a single origin of replication, whereas eukaryotes have many origins of replication.A plant would be able to replicate bacterial DNA that was inserted into its genome since the DNA structure is conserved throughout the animal and plant kingdoms.
The bacterial DNA will replicate, and the plant cells will produce bacteria proteins as a result of the inserted bacterial DNA, which will then perform its bacterial functions. The DNA's coding sequences and structural features are conserved between bacteria and plants, despite the fact that their regulatory sequences differ, which allows the DNA to be replicated and utilized in plants.

Why does the moose population outgrow its carrying capacity before decreasing and eventually stabilizing?
Lag time, Resource abundance, and resource depletion were some of the reasons for the moose population outgrowing its carrying capacity before decreasing and eventually stabilizing.
Moose have a very lag reproductive time. This makes it time-consuming to reach reproductive maturity for the new offspring to grow and reproduce the new generations. A limited reproductive system can decrease the population of moose.
The increase or decrease of any organism will depend on several factors like food, water, shelter, and also the capacity of the habitat to support a population. When the population will increase, then the environment will help the organisms to survive.

What experiment did the student conduct that involved the evaporation of alcohol
Students take part in this "alcohol gun" experiment to see what happens when an electric spark ignites ethanol vapor and air in a corked plastic bottle. The subsequent minor blast fires the plug across the room.
Liquor dissipates in light of the fact that, at a superficial, the particles of liquor interact with air. Vapor pressure, causes the liquid molecules at the surface to react and break their bond with hydrogen, causing it to begin evaporating. Alcohol has a rate of evaporation that is even faster than that of water.
When you start blowing on your hand, the alcohol and water will start to evaporate. Alcohol evaporates at a lower temperature than water does. That truly intends that for a similar measure of fluid, a more intense move happens during the dissipation of water contrasted and the liquor.

a mature red blood cell lacks a nucleus therefore it
A mature red blood cell lacks a nucleus; therefore, it cannot make a new proteins and will be worn out within few months. Option E is correct.
A mature red blood cell, also known as an erythrocyte, does not possess a nucleus. This characteristic allows for increased space within the cell to accommodate oxygen-carrying hemoglobin molecules. However, the absence of a nucleus restricts certain cellular functions, including the synthesis of new proteins.
Protein synthesis, essential for cellular maintenance and repair, requires the presence of a nucleus to provide the necessary instructions in the form of DNA. Without a nucleus, mature red blood cells cannot produce new proteins, limiting their ability to repair or regenerate themselves. Consequently, mature red blood cells have a limited lifespan and typically circulate in the bloodstream for about 120 days before being removed by the body's immune system and replaced by new red blood cells produced in the bone marrow.

the ldh activity curve is a rectangular hyperbola instead of a sigmoid curve
The LDH activity curve is a rectangular hyperbola instead of a sigmoid curve which is true.
The lactate dehydrogenase (LDH) activity curve is a rectangular hyperbola, which means that the reaction rate increases linearly with increasing substrate concentration until it reaches a maximum rate. At that point, the enzyme is saturated with substrate and can no longer increase its reaction rate. This is in contrast to sigmoidal curves, which show cooperative behavior where the reaction rate increases rapidly at low substrate concentrations, and then levels off at higher concentrations as the enzyme becomes saturated.
