Answer:
multiple fission
Explanation:
. There are many diseases that affect signal transmission along neural pathways. These includemultiple sclerosis (MS), myasthenia gravis, and amyotrophic lateral sclerosis (ALS or 'LouGehrig's Disease). Often, a component of these afflictions is a malformation or degenerationof the myelin sheath. MS is a demyelinating disease, which means that the axons of neuronsare intact but the myelin sheaths are damaged. Why would loss or damage to the myelinsheath be a problem for signal transmission, even if the axon was intact
Answer:
In neurons that are enveloped by myelin sheath, the nerve stimulus or neuronal action potential is transmitted in a saltatory way, that is, this action potential jumps in the spaces not surrounded by the myelin sheath and it is in this way that it is transmits much more efficient and faster.
Explanation:
Myelin neurons are those that are covered by myelin sheaths, this sheath is formed mainly by fatty acids, these fatty acids generate an alternate isolation along the axon so that the stimulus diffuses through the bare areas where they will have ionic channels premises in order to generate the potential for action.
If this myelin sheath disappears, not only is the response slower, but it is rendered incapable because an axon that does not have ion channels to spread the signal is discovered in the external environment.

Voluntourism: An Opportunity Too Good to be True
A Speech to the Student Body of Evergreen High
[1] Picture this: It's Spring Break, and you fly off to some country where there's lush rainforests and beautiful, blue coastlines to explore. There's also people in need, so you decide to blend your vacation with volunteering. Volunteering as a tourist, or voluntourism, seems like a great way to explore new regions and help people at the same time. However, this "volunteer plus travel" experience can actually harm local communities. While many teens might view traveling and volunteering abroad as a worthwhile adventure, there are more genuine and effective ways to make a difference.
[2] Most would agree that volunteering in general is a worthy use of time. However, what if you found out the children you are "helping" are actually being kept in poor conditions so voluntourists will spend money to come to the local area? Dale Rolfe, a supporter of ethical voluntourism, explains the shocking reality that "Animal sanctuaries and orphanages are often manufactured for the voluntourist...encouraging a cycle of exploiting the very animals and children the volunteers are trying to help."
[3] Proponents of the "volunteer plus travel" experience also argue that traveling to new places builds character and is a valuable way to learn about different cultures. With voluntourism, however, participants often pursue experiences that are all about them. For example, they sign up to build a school for a gold star on their resume, but they have no real building skills and take jobs away from local construction workers (Schulten). Or, they arrive to teach English but instead take selfies with the locals. One world traveler and ethical voluntourist believes voluntourism "can perpetuate small minded views of the world by taking insulated, fake, and structured experiences and selling them as unabridged and eye opening" (Carlos). The voluntour experience is a mirage. The voluntourist's eyes are not opened to real life at the destination, and lasting change is not achieved.
[4] If you want a genuine experience where you can see a lasting impact, there are better options than voluntourism. You can volunteer in your local community. Give an hour every week to your town's animal rescue. Serve monthly dinners to the homeless. Be a reliable, positive influence on a child who needs a mentor. Studies show that volunteering and forming lasting relationships with those you help has a positive impact on your physical and emotional health. In fact, blood pressure is reduced, memory is improved, and rates of depression are reduced (Michaels).
[5] There is another reason to look into alternatives to voluntourism. Did you know the average "voluntour" travel package costs $3,400 (Rolfe)? Could that travel money be better spent? If the world's citizens are your passion, it could go to an international organization. If you care about education, your funds can be used to buy books for students in faraway lands. If you want villagers to have clean water, contribute funds to local efforts to dig wells. If you want to experience a different culture, travel to the country as a guest, and learn from the locals how you can best help them after you've returned home. But do not voluntour.
[6] In reality, there are better ways to make a difference. Voluntourism might appear to be an adventure that blends travel and helping others, but it does little except provide a costly, superficial experience that might actually do more harm than good. So, volunteer where you are most needed-at home, where you can stay to see the job through and form genuine, lasting relationships. Choose a beautiful coastline closer to home and send the travel money you saved to an international organization that will put it to good use. Whatever you do, don't turn someone else's hardship into your vacation.

PHOTOSYNTHESIS AND CELLULAR RESPIRATION:
Photosynthesis is the process by which green plants obtain their food (glucose) using energy from sunlight. Cellular respiration is the process by which living organisms obtain energy by breaking down food molecules in their cells. Photosynthesis makes use of energy from the sun i.e. solar energy as its power source while cellular respiration releases the energy stored in glucose to power the process. Therefore, the statement that accurately describes the energy needs for photosynthesis and cellular respiration is: Solar energy is needed for photosynthesis, and chemical energy in the form of glucose is needed for cellular respiration.Learn more about photosynthesis and cellular respiration at: https://brainly.com/question/18728019?referrer=searchResults

1.¿Por qué es apropiado decir que casi todos los seres vivos dependen de la energía solar?Sara acaba de dar a luz a un bebé y esta agotada. Su amiga esta estudiando biología y evaluando el proceso de la fotosíntesis. 2.Sara decide sacar a su bebe al sol, en vez de darle leche, aludiendo que el bebé puede obtener energía de la luz solar. ¿Es esta una buena idea? ¿Por qué no puede el bebe utilizar la energía solar para producir ATP? No olvides incluir los organelos y procesos necesarios para la producción de ATP y de identificar al bebé de Sara como autótrofo o heterótrofo. En tu respuesta, contesta las siguientes preguntas. ¿Cuales son las diferencias entre la fotosintesis y la respiración celular? ¿Por qué no pueden los seres humanos procesar la energía solar y convertirla en energía química?
Answer:
1. La energía solar es la fuente principal de energía utilizada por organismos autótrofos para producir energía en forma de ATP a partir del proceso de fotosíntesis y almacenar esta energía en forma de enlaces químicos presentes en nutrientes orgánicos específicos. Los organismos autótrofos son fundamentales en la cadena alimenticia porque ellos representan la principal fuente alimento de organismos heterotrófos, con lo cual sustentando toda la vida en la tierra.
2. No, esta no es una buena idea porque los animales y seres humanos (incluyendo el bebe de Sara) son organismos heterótrofos, es decir, obtienen energía mediante el proceso de respiración celular, a diferencia de organismos autótrofos que almacenan energía a partir del proceso de fotosíntesis el cual requiere de la utilización de la energía solar. Tanto en la fotosíntesis como en la respiración celular los organismos producen una molécula llamada Adenosina trifosfato (ATP), la cual es considerada como la moneda energética de la célula porque sus enlaces químicos almacenan energía la cual es utlizada para diversos procesos celulares. Los autótrofos fotosintéticos poseen cloroplastos que son los orgánulos celulares encargados de capturar energía lumínica para sintetizar ATP, el cual es posteriormente utlilizado para sintetizar carbohidratos. Por otra parte, en organismos heterótrofos, las mitocondrias son las organlelas encargadas de producir la mayor cantidad de ATP generada durante el proceso de respiración celular, el cual requiere del combustible metabólico provisto por los alimentos.

Whats the difference between complete dominance, codominance, and incomplete dominance?
Complete Dominance:
Complete dominance occurs when one allele in a pair completely masks or overrides the expression of the other allele. In this case, the dominant allele is expressed phenotypically, while the recessive allele remains unexpressed.
The heterozygous genotype (having two different alleles) will exhibit the same phenotype as the homozygous dominant genotype (having two copies of the dominant allele).
Codominance:
Codominance occurs when both alleles in a pair are expressed equally and simultaneously in the heterozygous condition. Both alleles contribute to the phenotype without blending or overriding each other.
As a result, the heterozygous individual exhibits a phenotype that shows both traits associated with the two alleles.
Incomplete Dominance:
Incomplete dominance occurs when the heterozygous phenotype is an intermediate or blended expression between the phenotypes of the two homozygous genotypes.
Neither allele is completely dominant over the other, resulting in a third phenotype that is a mixture or combination of the traits associated with each allele.
In summary, complete dominance involves one allele fully masking the expression of another, codominance involves both alleles being expressed equally, and incomplete dominance involves an intermediate phenotype that is a blend of the phenotypes associated with each allele.

Describe what is going wrong in the body of a person with this condition that is preventing the right molecules from getting to the body’s cells. (asthma)
Answer:
Asthma is a chronic, inflammatory disease of the airways with permanent hypersensitivity. In those with a corresponding disposition (with an overly sensitive bronchial system), the inflammation leads to attacks of breathlessness as a result of acute narrowing of the airways - a so-called bronchial obstruction. This narrowing of the airways is caused by increased secretion of mucus, spasms of the bronchial muscles and the formation of edema of the bronchial mucous membrane; it is reversible through treatment. About 1 of every 10 individuals has or had asthma at least once.
