The matter surrounding a comet’s core is vaporized and forms a very bright halo of gases and an enormous cloud of hydrogen envelopes the head of the comet.
A comet is a tiny, icy body in space that may be identified by its stunning tail when viewed from Earth. Only when a comet is getting close to sun, the ice and particles that make up the comet's core heat up and start to dissolve.
Therefore,the material encircling the centre vaporises and creates a very bright halo of gases and a sizable cloud of hydrogen. Most comets follow a solar orbit. The atmosphere of gas created by the ice melting is what causes the coma.

Why would so many earthquakes originate along the slab of lithosphere that is descending into the mantle?
Answer:
As the slab descends into the mantle, rheology changes cause the plate to bend and deform, and generates these earthquakes. The trend of such events can be seen in cross-sections of subduction zones

¿Qué receptores se estimulan al oler la rosa? Explica el proceso a través del cual se percibe el aroma de la rosa.
Answer:
receptores olfativos especializados localizados en el epitelio olfatorio de la mucosa nasal
Explanation:
Las neuronas receptoras del olor se denominan receptores olfatorios. Los receptores olfatorios son células especializadas capaces de percibir miles de sustancias químicas diferentes y decodificar la información en miles de olores distintos. Estos receptores se localizan en la mucosa nasal de las fosas nasales. En el caso del olor a rosa, como así también cualquier otro olor, las sustancias químicas responsables del olor se dirigen al epitelio olfatorio de la mucosa nasal, donde se unen a receptores específicos localizados sobre filamentos sensoriales (cilios) en las membranas celulares de las neuronas especializadas. La unión desencadena una respuesta en la células neuronales, es decir, una descarga eléctrica que se propaga desde las fosas nasales hasta el cerebro, el cual decodifica la información (el olor) en una región conocida como bulbo olfatorio.
In the biosphere, _________________ is an important element in ATP (Adenosine triphosphate) and DNA (Deoxyribonucleic acid).
A. Phosphorus
B. Phosphate
C. Photosynthesis
D. Photons
In the biosphere, phosphorus is an important element in ATP (Adenosine triphosphate) and DNA (Deoxyribonucleic Acid), which is in Option A, as phosphorus is a crucial element in the biosphere as it is a component of both ATP (Adenosine triphosphate) and DNA (Deoxyribonucleic Acid).
What is phosphorus?Phosphorus is essential for the formation of the backbone of the DNA molecule, where it links the sugar and nitrogenous base components of the nucleotides. The phosphate group of each nucleotide forms a covalent bond with the sugar molecule of the adjacent nucleotide, forming a long, stable chain of nucleotides that make up the DNA molecule. The DNA molecule is responsible for transmitting genetic information from parent to offspring and serves as a blueprint for the development and function of living organisms.
Hence, in the biosphere, phosphorus is an important element in ATP (adenosine triphosphate) and DNA (deoxyribonucleic acid), which are in Option A.

What are the potential advantages and disadvantages of a major shift from the hard or traditional path of energy development to the soft or visionary path?
(These were the corresponding textbook pages, if needed) Please read the following from the textbook Environmental Science:
7th Edition - Chapter 17
9th Edition - Chapter 14
Answer:
Advantages of following the soft path, the argument here is alternative sources of power such as hydropower, geothermal energy , wind energy , and photovoltaic cells must be developed. This provides a alternative source to remain in a healthy environment and also function as the society we currently live in using the hard path. Disadvantages of following the hard path result with future generations fearing over the irreversible damage of climate change and the damage done to our atmosphere. The hard path argue that we should continue to operate in the future as we have in the past, except more efficiently. This is close to impossible and will only continue the negative effects the hard path( the path we have been following) results in. The major shift determines the outcome of this world, the futures worries or reliefs and ultimately the survival of humans.

Why do cells continue to divide in adult organisms?
Answer:
Although most of the tissues in adult organisms maintain a constant size, the cells that make up these tissues are constantly turning over. Therefore, in order for a particular tissue to stay the same size, its rates of cell death and cell division must remain in balance.
Explanation:
There are two main reasons why cells divide rather than continuing to grow larger and larger: The larger a cell becomes the more demands the cell places on its DNA. If the cell grows too large, it will have trouble moving enough nutrients and wastes across the cell membrane. Why does cell division remain important to an adult organism even after it is fully developed? It remains important because cells are renewed and wounds are healed in the process. When cells stop dividing to specialize in structure and function. When cells undergo programmed cell death.

List 5 ways that phosphorous is essential to plants & animal life on Earth.
Answer:
El fósforo (P) es esencial en todas las formas de vida conocidas, dado que constituye un elemento clave en muchos procesos fisiológicos y bioquímicos. Se trata de un componente presente en todas las células de todos los organismos vivos. El fósforo aparece en estructuras complejas de ADN y ARN que, al contener y codificar la información genética, controlan todos los procesos biológicos en las plantas. Además, el fósforo es un componente fundamental del sistema de transporte de energía en todas las células.
El fósforo no aparece aislado en la naturaleza, sino que se encuentra siempre combinado con otros elementos con los que forma los fosfatos que pueden ser muy complejos y presentarse bajo distintas formas en los suelos, el agua, las plantas, los animales y el hombre. Por tanto, se utilizará la palabra “fósforo” de forma genérica en lugar de identificar el fosfato concreto, aunque en la mayoría de los casos, se ofrecerán valores numéricos como P2O5 .
Hasta una época relativamente reciente, el crecimiento de las plantas y de los animales, y por extensión, la productividad de la agricultura, se veían limitados por la falta de fósforo, ya que anualmente solo se disponía de unas pequeñas cantidades de las rocas y de los minerales del suelo gracias a la acción erosiva de los elementos. Cuando los agricultores comenzaron a utilizar fertilizantes en el siglo XIX, los niveles de fósforo disponible para las plantas en muchos suelos eran todavía muy bajos. Por eso, hasta que no se comenzó a aplicar fósforo, la respuesta a otros nutrientes, especialmente al nitrógeno, era muy pequeña, es decir, que el fósforo era el nutriente limitante del crecimiento de las cosechas.
El fósforo desempeña un papel fundamental en la fotosíntesis, proceso por el que las plantas absorben la energía del sol para sintetizar moléculas de carbohidratos, es decir, de azúcares, que son transportados a los órganos de almacenamiento de las plantas. Este proceso es esencial para todas las formas de vida y constituye el primer paso en la cadena para producir alimentos, piensos y fibras.
Las raíces de las plantas absorben el fósforo del agua presente en el suelo y que se denomina solución acuosa del suelo.
Sin embargo, los compuestos de fósforo no son muy solubles y, como consecuencia, la cantidad de fósforo que la planta puede tomar de la solución acuosa del suelo tiende a ser mucho menor de la que necesita, especialmente cuando la planta se encuentra en un periodo de fuerte crecimiento. Por eso, el fósforo de la solución acuosa del suelo debería reponerse con una frecuencia de diez veces al día en esos periodos.
En un día, una cosecha de rápido crecimiento puede absorber el equivalente a cerca de 2,5 kg de P2O5 por hectárea (una hectárea equivale a 10.000 m2 ). De esto se deduce, por tanto, que es necesario que existan reservas adecuadas de fósforo en el suelo y que esas reservas puedan estar disponibles con facilidad. La mayoría de los suelos no abonados contienen una cantidad demasiado pequeña de fósforo, fácilmente aprovechable, para dar respuesta a la gran demanda de las cosechas, en especial durante ciertos periodos del ciclo de crecimiento. De ahí, que se imponga la necesidad de aplicar fertilizantes que contengan fósforo.
La carencia de fósforo afecta no solo al crecimiento de la planta y al desarrollo y rendimiento de la cosecha, sino también a la calidad del fruto y a la formación de las semillas. Asimismo, la carencia de fósforo puede retrasar la maduración de las cosechas, con lo que se retrasa la recolección y se pone en riesgo la calidad del producto.

Answer:
Top to bottom: 5, 3, 2, 4, 1
Explanation:
I'll take a shot! Here I go!
5 (Sun) = top; we get all our energy from the sun
Then 3 (plants); plants can convert sunlight into food for themselves via photosynthesis
Then 2; we're talking about herbivores that eat plants, right?
Then 4; these are probably~ carnivores
Then 1; when a living thing dies, these guys consume the corpse and return the energy to the ecosystem
Have a great day!
Answer:
Sun
Primary Producers
Primary Consumers
Secondary Consumers
Decomposers
Explanation:
Energy coming from the sun is converted into chemical energy (or glucose) by plants. Primary consumers (herbivores) eat those plants and gain the energy they produced. Secondary consumers (carnivores probably) eat the primary consumers and gain that energy. Then they die and decomposers (fungi) return their energy into the soil.

How is passive transport different from active transport?
A) Passive transport is substances moving from HIGH concentration to LOW concentration.
B) Passive transport requires energy input.
C)Passive transport happens regardless of concentration gradient.
D) Passive transport is substances moving from LOW concentration to HIGH concentration.
ASAP
Answer:
A
Explanation:
Passive transport does not require energy. The substances follow the concentration gradient, meaning they go from high to low. Active transport goes against the concentration gradient. Substances go from low to high, so it requires energy.
