The resting membrane potential is the difference in voltage through the neuronal membrane when the cell is at rest. -70 millivolts (mV) value is the _resting potential_ of the neuronal membrane.
What is the resting membrane potential?The resting membrane potential is the difference in voltage through the membrane between the neuron interior and exterior when the cell is at rest. This is when the neuron is not sending electric signals.
When the neuron is at rest, most ion channels are closed except for K+ channels, which let the ions get out of the cell according to its concentration gradient. Na+ channels remain closed.
Hence, when the neuron is at rest, the membrane is much more permeable to potassium ions (K+) than to other ions, such as sodium (Na+) and chlorine (Cl-).
This value is the _resting potential_ of the neuronal membrane.

How could the origin of organisms such as dinosaurs, whose gait allowed them to move without compressing their lungs, have led to emergent properties?.
The ability of dinosaurs to move without compressing their lungs helped them to effectively produce more energy requited for other emergent properties.
What was the advantage of being able to breathe with lungs?The lung is a special organ in the body of higher animals such as mammals and birds whose function is for gaseous exchange.
Possession of the lung gave an evolutionary advantage to organisms that have lungs as it enabled them to occupy various habitats on land as they could effectively use oxygen to produce energy.
Therefore, the ability of organisms such as dinosaurs to move without compressing their lungs helped them to effectively produce energy for other emergent properties.

How does dna replication affect the number of chromosomes in the cell?.
Answer:
Following DNA replication, the DNA content doubles again to 4c, but each pair of sister chromatids is still counted as a single chromosome (a replicated chromosome), so the number of chromosomes remains unchanged at 2n.

What causes folded mountains to form?
Collision of continental plates
Collision of a continental plate with an oceanic plate
Vertical shifting along a fault line
Lava emerging from a crack or fissure in the crust
Answer: Fold mountains occur near convergent or compressional plate boundaries. Plate movement creates fold mountains as the plates move towards each other. This movement causes layers of sedimentary rock on the ocean floor to become wrinkled and folded. These mountains are found between two continental plates.

Explain the life cycle of gymnosperms in detail.
Answer: In gymnosperms, the gametophyte generation takes place in a cone, which forms on the mature sporophyte plant. Each male gametophyte is just a few cells inside a grain of pollen. Each female gametophyte produces an egg inside an ovule.
Hope this helps!
Answer:
The male cones release pollen into the air. The wind then carries the pollen to the female cones. The pollen gets stuck in a sticky liquid produced by the ovule. Sperm from the pollen fertilize the egg in the ovule. The ovule then develops into a seed. When the seed is mature, it is dispersed. If conditions are good, the seed grows into a seedling, which grows into a tree. The tree produces cones, and the cycle begins again.

The relationship between the amount of energy available for use and the amount of entropy in a food chain differs between trophic levels. why would the amount of entropy increase from one trophic level to another in a food chain or energy pyramid? a. the available energy from one trophic level to another increases b. energy is lost at each level as heat, which increases randomization c. the amount of biomass decreases from one trophic level to another d. the available energy at each level may either increase or decrease, creating randomization
The amount of entropy in a food chain differs between trophic levels the correct option is "B" energy is lost at each level as heat, which increases randomization.
What is the 10 per cent law of energy?The 10% Rule indicates that when energy is flowing in an ecosystem from one trophic level to the next, only ten per cent of the energy will be passed on. A trophic level is the position of an organism in a food chain or energy pyramid.
Thus, energy is lost at each level as heat, which increases randomization.

In which level of the intertidal zone would you expect to find the most types of wildlife in the ecosystem?
help
Answer:
The low-intertidal zone
Explanation:
The low intertidal zone has the most organisms considering it has the most favorable conditions, since it isn't subject to tides uncovering this area.
Answer: The correct answer is the low intertidal zone since it is only exposed during low tide and has the greatest biodiversity of the three zones because it provides more favorable conditions for those organisms that cannot tolerate air exposure for longer amounts of time.

7. ) Most of a cell's growth and activity occurs in the ______ phase.
a.) s phase
b.) m phase
c.) G0
d.) G2
e.) G1
Answer:
Interphase (A.K.A. S Phase)
Explanation:
Hope this helps.
Most of the cell's growth and activity occurs in the S-phase of mitosis. During the S-phase, a cell grows in size and genetic material duplicates. Thus, the correct option is A.
What is Mitosis?Mitosis is the division of cell in which the DNA or the genetic content of the cell remains constant from one generation to the next generation. Mitosis consists of interphase and M-phase. During the interphase, cell prepares for division while in the M-phase the cell undergoes division.
The S phase of a cell cycle occurs during the interphase after the G1 phase, before the M-phase, and it is responsible for the replication of DNA. In this stage, the genetic material of a cell is doubled before it enters the M-phase, allowing enough amount of DNA to be split into the two daughter cells.
Therefore, the correct option is A.

When does the mitotic spindle attach to the kinetichore?
Answer:
The Prometaphase.
Explanation:
Typically in biology the prometaphase is overlooked. It is between the prophase and the metaphase, and is the exact point in which the mitotic spindles attach to the kinetochores. Metaphase, which occurs directly afterwards, is when the chromosomes are lined up to be split and pulled towards opposite sides of the cell.
