(d) A thick, myelinated axon is probably going to propagate an action potential fastest.
Axons have the ability to obstruct the ability of particles to diffuse through the cytoplasm. Contrarily, opposition is correlated with filament width. Axons with weak myelinated axons will therefore provide more resistance, and Na+-based depolarization will propagate more slowly.
Constant conduction is the spread of an activity potential along an unmyelinated axon. Large numbers of sodium (Na) particles are constantly rushing into the cells because voltage-gated sodium (Na) channels are regularly open here for conduction.
Axons have the ability to guard particles while still allowing them to diffuse into the cytoplasm. The length of the strands and obstruction have a diametrically opposed connection. This escape is incredibly difficult since myelin is present, effectively protecting the action potential. Additionally, the myelin sheath-covered area of the neuron's capacitance is reduced.
The myelinated axon as a result accelerates the action potential impulse. The axon can spread more quickly the thicker its sheath.
Question

a. a thin, unmyelinated axon
b. a thin, myelinated axon

Which answer best identifies the difference between the two types of cellular transport? (B.4B) Question 3 options: Active transport uses ATP to move molecules against the concentration gradient. Facilitated diffusion uses ATP to move molecules down the concentration gradient. Diffusion move molecules through the cell membrane from an area of low to high concentration. Active transport uses ATP to move molecules against the concentration gradient. Active transport uses ATP to move molecules against the concentration gradient. Facilitated diffusion does not need ATP, but uses protein channels to move molecules down the concentration gradient. Facilitated diffusion does not need ATP, but uses protein channels to move molecules down the concentration gradient. Active transport uses ATP to move molecules down the concentration gradient.
Answer:
Active transport uses ATP to move molecules against the concentration gradient.Facilitated diffusion does not need ATP, but uses protein channels to move molecules down the concentration gradientExplanation:
Transmembrane proteins, among others, are the channel proteins and the carrier proteins, and they are in charge of substances transport into or out of the cell.
Channel proteins are involved in passive transport, and facilitated diffusion is a kind of passive transport. Facilitated diffusion transport hydrophilic molecules that can not freely move through the membrane. Channel proteins carry them from one side to the other of the membrane, following the electrochemical gradient, so they do not need energy to carry in or out substances. Uncharged molecules´ movement depends on concentration gradients, while ions´ movement depends on an electrochemical gradient.Carrier proteins are involved in active transport. Active transport acts against the electrochemical gradient, so it does need the energy to transport substances. It carries molecules from a low concentration side to a high concentration side. The used energy comes from ATP (Na-K bomb) or the membrane´s electric potential.

SOOOOMMMEEEE OONNNEEE PLLLEEEASSSEEE HEEELPPP ME. WITH THE RED PART ON THE TOP RIGHT CONER I PICKED ALANTIC PUFFIN BECUSSE IT LOOKS LIKE THR BARN OWL IT SAY I CHOSSE ..... BECUSEE... NEED HELP WITH THAT NOOOOOO LINKS
Answer:
they do kinda look similar although i would choose the owl, mainly since there a top predator in the birb species, they hunt at night cause they know thats a time where the main preys at, they can take down full turkeys, other birds of prey/raptors, as well as abduct full grown dogs and cats depending on the size of them (that has happened to me lol) they have a long life span, they look like grey aliens in disguise as an animal to be amongst the human race, as well as a lot of alien abduction stories and alien sightings the people report seeing large owls either before or after there iincounter, i can add more reasons to like owls if you want
Explanation:
They also poop out there full preys skeleton so if you ever find owl poop there will most likely be a full skeleton of an animal in there
Explain the role of both biotic and abiotic factors within a nutrient cycle.
Answer:
Answer. Biotic factors are the living things in an ecosystem so they do not recycle. Abiotic factors are the different physical and chemical components available like temperature, air, water, minerals, rocks,and PH. Not ll of them are recycled.
The role of both factors within a nutrient cycle is very important because nutrients cycling through biotic and abiotic systems constantly.
Explain the role of both biotic and abiotic factors within a nutrient cycle?Plants, animals, microorganism and organic matter are the biotic locations of nutrients while on the other hand, the atmosphere, water, and soil represent the abiotic locations. Nutrients are constantly moving or cycling through biotic and abiotic systems.
So we can conclude that the role of both factors within a nutrient cycle is very important because nutrients cycling through biotic and abiotic systems constantly.

What is reflex arc?A reflex arc is a neural pathway that mediates a reflex action. It is a rapid and automatic response to a specific stimulus that does not require conscious thought or decision-making from the brain. When a sensory receptor in the body, such as the skin or muscles, is stimulated, a nerve impulse is transmitted to the spinal cord, where it is processed by an interneuron.
The interneuron then sends a signal through a motor neuron to the effector, such as a muscle, causing a rapid and involuntary response, such as pulling your hand away from a hot stove. This entire process occurs without conscious control from the brain, allowing for quick and protective responses to potentially harmful stimuli.

Describe the flow of energy to the lion using a food chain from the food web that includes a rabbit.
Answer:
10%
Explanation:
the sun gives energy to the grass (to make it easier to understand, say the sun gives 100un of energy to the plants)
from there, the rabbit eats the grass( 10% of 100 is 10, so the rabbit gets 10un of energy)
and the, a lion eats the rabbit (10% of 10 is 1, so the lion gets 1 un of energy)
every single time a predator consumes prey, it only gets 10% of what the prey gets from its prey.
Hope this helps :)
