12. Why does a New Moon appear black to us?
Explanation:
the moon does not have an atmosphere so light does not scatter therefore the moon looks black.
Answer:
as its "new moon" phase the moon is always black.it happens at the time of the month when the moon passes through the same part of the sky as the sun and as such the moon's dark or unilluminated side facing the earth so there really is nothing to see

What causes precipitation to fall to the Earth’s surface?
Answer:
The drops of water in the clouds are heavy enough to fall.
Explanation:
Precipitation forms in the clouds when water vapor condenses into droplets of water. When the droplets are heavy, they fall to the Earth. These droplets can fall in the form of rain, hail, or snow.
2. How is the synthesis of ATP in the electron trans-
port chain of mitochondria similar to the syn-
thesis of ATP in chloroplasts?
Answer:
Explanation:
They’re nearly identical in the actual events of ATP production.
Both take protons that have been ‘pumped’ into a membrane-contained area of the organelle (chloroplast or mitochondrion). These protons flow through the F1/F0 ATP synthase, which does the actual jamming of a phosphate onto ADP to create ATP.
Both pumped those protons by ‘harvesting’ the energy of electrons through passaging those electrons between special protein complexes in a membrane (electron transport chains).
The key differences are in where those energized electrons came from in the first place. In mitochondria, the electrons were ripped from sugar pieces in the Kreb’s/TCA cycle. In photosynthesis, electrons were energized by sunlight (and are then replaced by taking non-energized electrons from water, which is where oxygen is made)
HOPE IT HELPED YOUEn un cultivo de células vegetales se introdujo una mutación genética que produjo como consecuencia la incapacidad de estas células para polimerizar todo tipo de moléculas de glucosa. ¿Que consecuencias podrían haber para estas células?
Explanation:
Aun cuando los procesos de replicación del material genético son muy precisos, no son perfectos, por lo que pueden producirse errores que generan cambios. Una mutación es una variación espontánea o inducida del genoma, un cambio permanente y heredable en la secuencia del ADN, en nucleótidos, o bien en la disposición del ADN en el genoma.
Estos cambios o mutaciones se deben a alteraciones de la información genética. Las consecuencias dependen entonces del nivel de afectación: desde cambios en la secuencia nucleotídica, en los genes o los productos génicos, hasta en los tipos celulares involucrados.
Todos los seres vivos cuentan con sistemas de verificación y reparación de los procesos celulares. En el caso de la replicación del ADN existen sistemas de reparación específicos y bien coordinados, pero en ocasiones las lesiones del ADN que escapan a esta verificación serán las causantes de ocasionar mutaciones; por lo tanto, la efectividad de la lesión dependerá tanto de la tasa de división celular, como de la eficiencia de los mecanismos de reparación contra el aumento en las lesiones al ADN. Cuando ambos factores están incrementados, el resultado será una mayor generación de mutaciones o mutagénesis (y carcinogénesis).

Alternative Title: primary plant succession
Primary succession, type of ecological succession (the evolution of a biological community’s ecological structure) in which plants and animals first colonize a barren, lifeless habitat. Species that arrive first in the newly created environment are called pioneer species, and through their interactions they build a simple initial biological community. This community becomes more complex as new species arrive. Primary succession is distinguished from secondary succession, which is the recovery of an existing biological community after a disturbance sets back the community’s ecological structure to an earlier stage.
Primary succession
Primary succession
Primary succession begins in barren areas, such as on bare rock exposed by a retreating glacier. The first inhabitants are lichens or plants—those that can survive in such an environment. Over hundreds of years these “pioneer species” convert the rock into soil that can support simple plants such as grasses. These grasses further modify the soil, which is then colonized by other types of plants. Each successive stage modifies the habitat by altering the amount of shade and the composition of the soil. The final stage of succession is a climax community, which is a very stable stage that can endure for hundreds of years.

QUICK FACTS
RELATED TOPICS
Ecological succession
Pioneer species
Lava-sterilized landscapes, newly formed sand dunes, and rocks either deposited or scoured by retreating glaciers are examples of settings in which primary succession often occurs, because these places either lack soil or their soil cannot sustain life. On newly created volcanic islands, for example, after the rock cools, seeds blown by the wind may lodge in crevices, germinate, and take root. Often these first colonizing plants are weedy species, such as fast-growing grasses and lichens, that do not grow tall but do reproduce quickly. After these plants germinate and grow, they die and decompose, and their remains create pockets of soil in which other plants, as well as fungi, can become established. Over time, such fast-growing vegetation covers more and more of the island, and seeds from other, hardier, taller-growing plants arrive on the wind or are transported by birds that begin to use the island as a stopover during migration.
Surtsey
Surtsey
Surtsey, a volcanic island off the southern coast of Iceland, emerged from the Atlantic Ocean in a fiery eruption in November 1963. Shortly thereafter plants such as sea rocket (Cakile arctica), sand ryegrass (Leymus arenarius), oysterleaf (Mertensia maritima), and seaside sandplant (Honckenya peploides) colonized the island. Much of Surtsey's vegetation is composed of lichens and mosses. However, some higher plants such as the dwarf willow (Salix herbacea) and tea-leaved willow (S. phylicifolia) have grown on the island since the 1990s.
ARCTIC IMAGES/Alamy
These new arrivals shade out sun-loving grasses, shrubs, and other pioneer species, and their cast-off parts decay and add to the soil, altering it by mixing with soil particles left by the decay of earlier plants. More plants and animals arrive (the latter rafting over on flotsam or flying from nearby islands or the mainland), and some become established on the island. The ecosystem changes with each new arrival. Over several decades, the biological community transitions from collections of pioneer and intermediate species to a climax community—that is, a relatively balanced ecological stage whose ecological structure and species composition are far less volatile than those of earlier stages.

Rocks form in horizontal layers. However, as shown along mountainsides, rock layers can become twisted or bent. The work of James Hutton and Charles Lyell helped to explain observations of twisted or bent rock layers. What was one of their conclusions? A. Earth is extremely old, and Earth processes acted gradually to twist or bend rocks. B. Earth is only a few thousand years old, and Earth formed with many twisted or bent rocks. C. Earth is only a few thousand years old, and Earth processes acted much more rapidly in its early history. D. Earth is extremely old, and Earth formed with many twisted or bent rocks.
Answer:
A. Earth is extremely old, and Earth processes acted gradually to twist or bend rocks.
Explanation:
The land is a system that lives in constant movement, in addition to being subjected to several factors that can modify its structure and composition. The earth is a very old planet and has been subject to these factors since its creation. In addition, more factors appear with the passage of time, creating several terrestrial processes that have the ability to gradually modify the earth even geologically, being able to twist and bend the rocks.
