Explain how mutated DNA would produce proteins responsible for sickle cells rather than producing proteins responsible for normal red blood cells
Answer:
Explanation:
Sickle cell anemia is a result of the point mutation, and in a change in just one nucleotide in a gene for hemoglobin. This mutation will cause the hemoglobin in the red blood cells to distort to a sickle shape when deoxygenated. "The sickle-shaped blood cells clog in the capillaries, cutting off circulation."

2) Primero, Sistema Nervioso Parasimpático. Luego, Sistema Nervioso Simpático.
3) Sistema Nervioso Parasimpático.
Explicación:
La pregunta está incompleta, falta la siguiente parte:
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.

Why does DNA replication occur before mitosis and cell division?
Answer:
Explanation:
DNA replication needs to occur because existing cells divide to make new cells, so that the DNA needs to be copied before cell division so that each new cell receives a full set of instructions.
DNA replication - It is the process of producing two identical copies of DNA molecules from one original DNA molecule.
The cell cycle is the series of events that lead to a cell's genome duplication and final division into two daughter cells.
It consist of two main phases - Interphase and M phase
DNA replication occurs at the interphase during S phase of the cell cycle.
Mitosis begins after interphase.
DNA replication occurs before mitosis and cell division so that each newly formed daughter cell receive full set of chromosomes as of parent cell in their nucleus. DNA contains instructions that helps the newly formed cells to operate properly.

Why do genetically different cells form during meiosis?
Answer: meiosis creates new combinations of genetic material in each of the four daughter cells. These new combinations result from the exchange of DNA between paired chromosomes. Such exchange means that the gametes produced through meiosis exhibit an amazing range of genetic variation.

What might happen if you make a hole using a pointed object to any of the two small
balloons?
Due to high pressure on the small hole, the balloon will burst.
The balloon will burst if we make a hole using a pointed object because there is a lot of pressure on the small opening. When we male a hole in a balloon with a pointed object such as needle, the air inside the balloon trying to escape from the small opening which puts pressure on the small hole which the balloon can't tolerate and as a result the balloon will burst so we can say that the balloon will burst due to presence of high pressure.

make a claim about whether air is matter
Answer:
Air is matter because it's make up of a mix of different gases. These are made up of elements such as hydrogen, oxygen, and nitrogen, which are made of matter.
Explanation:
is there a word count requirement?
Answer:
Air is matter because it takes up space and has mass.
A way to prove this is by inflating a balloon. Before inflating, the balloon was empty and shapeless. When the balloon was filled with air you know it filled with something. That would be matter.

Which statements could be categorized in the "Asexual" section of the Venn diagram? Check all that apply
Answer:
The right answer are : mitosis, diploid cells, and identical DNA.
Explanation:
The answers "two cell divisions" and "gametes" refers to a division by meiosis which is a sexual reproduction.
Asexual reproduction or asexual reproduction is a mode of reproduction, which - as opposed to sexual reproduction - corresponds to the capacity of living organisms to multiply alone, without a partner, without involving the fusion of two gametes of opposite sexes. Asexual reproduction is observed in multicellular (animal and plant) and unicellular organisms. In botany, the term often used for the asexual multiplication of plants is vegetative multiplication. In all cases of asexual reproduction, the result is identical to the mother.

If PCBs escaped into the river in large amounts and entered the lower levels
of the food chain, what would be the likely outcome?
Answer:
Over time, PCBs would collect in top predators such as salmon, making them unsafe for human consumption.
Explanation:
PCBs last a long time in the environment before breaking down and may find their way into the food chain. Low levels of PCBs can be found in fish, shellfish, meat, poultry, milk, dairy products, and other foods. Since PCBs have not been made since 1977, the levels in the environment have been declining over the past several years. Predators at or near the top of the food chain (e.g. birds, fish) have the highest levels of PCBs in their bodies.
