Answer:

Are usually present, but are no longer functional.

Explanation:

Vestigial structures are "evolutionary remnants". They are anatomical features that were once important throughout the organism's evolution, but now have no function. However, they aren't harmful either, so there has been no selective pressure for them to be removed via evolution.

Good examples in humans are the tail bone, wisdom teeth, and the appendix.

Answer:

burning fossil fuels and decomposition of dead organisms

Explanation:

A significant amount of the carbon in the biosphere is returned to the carbon cycle through decomposition by fungi and bacteria. Much of what is not decomposed becomes fossil fuels. When humans burn fossil fuels for energy, carbon is returned to the atmosphere.

The process that returns carbon from the vast reservoir of animal bodies to the active carbon cycle is called decomposition, which is present in Option A, as when an animal dies, its body is broken down by decomposers, such as bacteria and fungi.

The decomposition process is essential for the cycling of carbon in the environment. When an animal dies, the organic molecules that make up its body become available to decomposers. These decomposers use enzymes to break down the complex organic molecules into simpler compounds, such as sugars, amino acids, and fatty acids.

Hence, the process that returns carbon from the vast reservoir of animal bodies to the active carbon cycle is called decomposition, which is present in Option A.

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.

However, as described in the question. each cell organelle has specialized function that assists the cell carry-out it's own function as a whole. Cell organelles include cell membrane, smooth and rough endoplasmic reticulum, vacuole, golgi complex, lysosomes, nucleus, mitochondria, chloroplasts among others.

Of these cell organelles, only three were mentioned in the question

Nucleus: This houses the chromosome which stores genetic material. This organelle is found in plant and animal eukaryotic cells. Indeed, eukaryotic organisms are sometimes described as organisms that have well defined nucleus.

Mitochondria: They are found in most plant and animal eukaryotic cells. They are usually referred to as the power house of the cell as they provide energy-rich chemical compounds (called ATP) for the cell's activities.

Chloroplasts: These are cellular structures/organelles that are found only in  green plants - they are cellular machinery for photosynthesis in plants. They also contain the green pigment called chlorophyll which is responsible for the green colour of green plants.

The type of the cell in which the organelles mentioned in the question are listed above.

Answer:

All living organisms are classified into groups based on very basic, shared characteristics. Organisms within each group are then further divided into smaller groups. These smaller groups are based on more detailed similarities within each larger group. This grouping system makes it easier for scientists to study certain groups of organisms. Characteristics such as appearance, reproduction, mobility, and functionality are just a few ways in which living organisms are grouped together. These specialized groups are collectively called the classification of living things. The classification of living things includes 7 levels: kingdom, phylum, classes, order, families, genus, and species .

1) Sistema Nervioso Simpático.

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:

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:

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.

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.

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.
