2) Estás durmiendo luego de una abundante cena, de pronto, sentís unos golpes tremendos, te tiran la puerta abajo y unos encapuchados te apuntan con algo que parece un arma ¡chau digestión! Sentís que los músculos se ponen cada vez más tensos.
3) Tus amigos te jugaron una broma pesada. ¡Los querés matar! Sentís que poco a poco tus pulsaciones vuelven al ritmo normal ¡Qué día!
Respuesta:
El sistema nervioso es un conjunto de células que controlan todas las funciones del cuerpo, incluyendo órganos y músculos. Para llevar a cabo dichas funciones, el sistema nervioso se encuentra dividido en dos grandes partes:
Sistema Nervioso Central (SNC): Conformado por el cerebro y médula espinal, que procesa la información recibida para mandar instrucciones al cuerpo sobre que funciones realizar.Sistema Nervioso Periférico (SNP): Conformado por nervios que se extienden desde la médula espinal hacia todo el cuerpo y son las responsable de captar señales que envían al cerebro.El SNP, se divide entonces en Sistema Nervioso Somático, el cual conecta al SNC con todos los músculos para modular sus movimientos voluntarios e involuntarios y transmite la información desde el exterior hacia el interior. Y también se divide en Sistema Nervioso Autónomo (SNA) el cual a su vez presenta otras dos ramificaciones:
Sistema Nervioso Simpático: Controla respuestas que activan funciones y preparan al cuerpo para responder a situaciones diversas de estrés y peligro.Sistema Nervioso Parasimpático: Tiene una acción opuesta, para retornar al organismo a un estado de equilibrio.Por lo tanto, el SNA se encuentra en la periferia y desde el cerebro salen nervios hacia todo el cuerpo, llamados fibras eferentes, enviando información de las vísceras y algunos órganos para controlar sus funciones de acuerdo a los estímulos percibidos. Por lo tanto, esta división del sistema nervioso controla movimientos involuntarios como la digestión, presión sanguínea, reflejos involuntarios, etc.
Por ejemplo, frente a una situación de estrés o de peligro, el Sistema Nervioso Simpático hace que el cuerpo entre en un estado de alerta para así estar preparado para defenderse y/o huir. Entonces, se envían señales a glándulas y músculos para que lleven a cabo ciertas funciones como dilatar pupilas, liberar adrenalina, inhibir la digestión, aumentar la presión sanguínea, etc. Todo esto ayuda al cuerpo a utilizar las energías disponibles para huir o defenderse frente al peligro y no malgasta las energías en funciones que no son prioridad en ese momento (como la digestión, entre otras) Cuando la situación se termina y la persona se tranquiliza, el Sistema Nervioso Parasimpático retorna al organismo hacia un estado de equilibrio causando la constricción de pupilas, liberando acetilcolina estabilizando la presión, retomando la digestión, etc. De esta manera, el organismo continua llevando a cabo sus funciones normales.
1) En este caso, la persona se encuentra muy nerviosa por estar siendo evaluada por un profesor y frente a toda la clase. Entonces, el Sistema Nervioso Simpático hace que la sangre se dirija a los músculos y el cuerpo se prepara para "huir" dejando de lado otras situaciones como ir al baño. La sudoración tiene la función de bajar la temperatura corporal, y los temblores vienen por parte de las palpitaciones y la presión sanguínea alta.
2) Mientras la persona duerme y hace la digestión, actúa el Sistema Nervioso Parasimpático, ya que el cuerpo se encuentra tranquilo y en resposo, sin situaciones estresantes o de peligro y puede funcionar de forma normal como siempre. Pero en el momento en el que la persona escucha ruidos, se despierta de golpe y al ver gente extraña la persona se pone nerviosa, se inhibe la digestión y otras funciones no primordiales para la supervivencia y la persona se encuentra en estado de alerta. En este caso, actúa el Sistema Nervioso Simpático. También se tensan los músculos, preparándose para ser usados y escapar.
3) Cuando la persona se da cuenta que los encapuchados eran amigos y solo era una broma, se calma, y baja el ritmo cardíaco por lo que actúa el Sistema Nervioso Parasimpático. La persona ya no necesita estar en estado de alerta para escaparse y huir.

Which of the following is the most likely reason the Moon can NOT support life?
А
It has many craters, indicating that it has an atmosphere too weak to protect life
B
It has many craters, indicating that is has a magnetic field too powerful for life.
С
It has many dark spots, indicating volcanic activity too extreme for life.
D
It has many light spots, indicating frozen ice that is too cold for life.
Answer:
A
Explanation:
B is not true because the amount of craters does not indicate how powerful the magnetic field is, it indicates how much gravity there is.
C is not true because the dark spots are igneous rock, dried lava. That means that there WAS volcanic activity, in the past.
D is not true because the light spots on the moon are not ice, they are simply a lighter colored rock.
A is true because meteors will burn up in the atmosphere of planets because of friction, so not all the meteors will hit said planet. But if there isn't an atmosphere, all of the meteors will hit that planet. (or in this case, moon)

Compare and contrast Meiosis and Mitosis, how are they similar and how are they different?
Answer:
Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells.
Answer:
1. meiosis require two nuclear division but mitosis requires only one nuclear division
2. meiosis produces four daughter divisions, and there are four daughters cell following cytokinesis. Mitosis followed by cytokinesis result in two daughter cells
3. in meiosis, the four daughter cells are haploid and have half the chromosome number as the parent cell. In mitosis, the daughter cell have the same chromosome number as the parent cell
4. in meiosis the daughter are genetically dissimilar to each other and to parent but in mitosis, the daughter cells are genetically identical to each other and to the parent.

Explanation:
What is a small ecosystem in danger of compared to a large and diverse ecosystem?
Answer:
See the answer below
Explanation:
A small ecosystem is in danger when compared to a large and diverse ecosystem because the genetic variability in a small ecosystem is low and a small disruption can wipe out the populations within the ecosystem. This is unlike in a large ecosystem where this is a high genetic variability that gives the populations within the ecosystem resilience against disturbances.
There are enough alleles within the genetic pool of a large and diverse ecosystem to withstand disturbance regimes unlike in small ecosystems where the alleles are few. Hence, a little disturbance can endanger the entire population in a small ecosystem and put them at the risks of extinction.

Knowing what you know about how a substance travels in diffusion, in
order for oxygen to leave the alveoli and enter the blood, there would be
concentration of oxygen in the alveoli compared to the
blood. *
A.higher
B.Lower
Answer:
the oxygen should be concentrated in the alveoli
Explanation:
Diffusion: The movement of molecules from a region og higher concentration to a region of lower concentration.
So when the Oxygen is concentrated in the alveoli only then it can move towards the blood
Diffusion is a passive transport system which means it doesnt need energy in the form of atp molecules
if the molecules move from a region of lower concentration to a region of higher concentration it needs atp molecules which is energy and is called active transport system
The answer should be "HIGHER."

Tina-Marie accidentally left her water bottle outside on a freezing, winter night. The next day, the water bottle, which is now filled with ice, ruptured. Based on her observations, Tina-Marie forms a hypothesis about freezing water and volume. Identify a hypothesis Tina-Marie can investigate. Then describe an experimental procedure for investigating the hypothesis.
Answer:
Hypothesis, Ice is less dense then water.
Explanation:
They could test this by attaining the density of ice and water, the density of Water is 1g/ml and if the ice floats that means ice is less then 1 g/ml which means ice is less dense. This is relevant to the water bottle because the Ice expanded due to it being less dense causing the water bottle to rupture
