Check all that apply as characteristics of myelinated axons. Check All That Apply Myelinated axons transmit nerve impulses via c
stiv31 [10]

Answer:

Myelinated axons utilize fewer voltage-gated channels than unmyelinated axons of the same length and diameter.

Myelinated axons are more energy efficient than unmyelinated axons.

Explanation:

Neurons are cells that specialize in transmitting messages to each other using a type of electrical signal. These signals carry information from outside your body to the brain, while others are the instructions for the various organs, glands and muscles to carry out functions.

Neurons receive these signals from other neighboring neurons through their dendrites. The signal then travels to the soma of the neuron, which is the main body of the cell, and finally<u> travels down the axon to the synaps</u>e (space between the end of a neuron and another cell). The axon is a neuronal extension through which the electrical signal travels, extending from the soma to other neurons.

<u>There may be layers of myelin, which consist of a layer of fat, covering the axons and where they have the function of acting as insulators to help keep the electrical signal inside the cell, which makes it move faster increasing the speed of transmission of the nerve impulse</u>.

1) Myelinated axons transmit nerve impulses via continuous conduction. FALSE. In the axon, nodes of Ranvier are found at regular intervals along the length of the axon in the myelin sheath that surrounds it. These are small spaces that expose the axon membrane to the extracellular fluid and serve to allow the nerve impulse to travel faster, in a jumping manner and with less chance of error.

2) Myelinated axons transmit nerve impulses in the same manner as unmyelinated axons. FALSE. In an unmyelinated axon, the movement of voltage across the membrane is due to ion flux that is limited by the time it takes for sodium ions to diffuse into the axon. Myelinated axons conduct faster because they are shorter than unmyelinated axons. In the latter, transmission is continuous but slower.

3) Myelinated axons utilize fewer voltage-gated channels than unmyelinated axons of the same length and diameter. TRUE. The action potential conduction jumps from node to node, thereby they need fewer voltage-gated channels. Unmyelinated axons need voltage-gated channels in along the entire axon.

4) Myelinated axons are more energy efficient than unmyelinated axons. TRUE. The rate at which sodium input through one node can depolarize the axon at the next node is related to the current and capacitance across the membrane. Myelinated axons have faster action potential conduction because it jumps from node to node, thereby they use less energy because they don't have to travel the entire length.

5) Myelinated axons would be unaffected by diseases that attack the CNS. FALSE. For example, Multiple sclerosis (MS) is a demyelinating disease of the CNS in which the immune system attacks the myelin sheath or the cells.

Help please !! I really don’t understand this much☹️
morpeh [17]
Ok, so I wrote these out just to make it a little bit easier for you to understand what I am about to explain.

So for the first one you have two different traits that can be inherited- having freckles or having no freckles, F and f respectively. The dominant trait (or having freckles) is shown by the capital F, and is almost always expressed over the recessive trait, or the lowercase f. So, for example, if you have a genotype of Ff, the trait having freckles will show up instead of not having freckles. The only way that you could have the trait of no freckles show up is if there are two recessive alleles for having no freckles, or ff. In this case, you have two parents who are both heterozygous for the trait of having freckles, so in other words the mother has Ff and the father has Ff. Each parent passes down one allele to the offspring, so since you are breeding Ff and Ff, you should result in having the possible genotypes of FF, Ff, Ff, and ff. This means that there is a 25% chance that the offspring will be homozygous for having freckles, a 50% chance that the offspring will be heterozygous for having freckles and a 25% chance that they would be homozygous for having no freckles, or a 1:2:1 ratio.

Incomplete dominance is a little bit different that just a normal monohybrid cross. Instead of just the dominant gene showing up in a heterozygous genotype, both traits show up. So like the question says, if a homozygous red flower plant was crossed with a homozygous white flower plant, their offspring would not just be white or red, they would be pink because it is a mixture of white and red. So then if you crossed the heterozygous, or Rr plants, the result would be a 25% chance of getting a homozygous RR red plant, a 50% chance of getting a pink Rr plant, and a 25% chance of getting a white rr plant, or another 1:2:1 ratio.

Sorry for the wordy answer, but hopefully this helps you understand this a little better :)

With an ethnocentric approach, a company applies the morality used in its ________. A. host nation B. industry C. general societ
Gennadij [26K]

Answer: The correct answer is home country

Explanation:

An ethnocentric approach is driven by a tendency to believe that one's own culture, tradition or way of life is normal and superior to all others anywhere in the world.

Thus, the company regardless of its location would apply the morality (core values and beliefs) used in its HOME COUNTRY
