How do pioneer species make ecological succession possible on an island formed from a volcanic eruptions

Biology

SIZIF [17.4K]3 years ago
3 0

Answer:

The correct option is <em>3. they break down rock into soil in which plants can grow</em>

Explanation:

When a disaster is such huge that even the soil and organic matter get removed from the place, then the succession that will occur in such kind of place will be termed as primary succession. For example, a volcanic eruption or an earthquake.

On the other hand, if after a disaster some of the organic matter remains on the land, then the succession that will occur will be termed as secondary succession. E.g a succession after fire

In primary succession, the pioneer species will be plants that require less soil such as the lichens. The lichens will break down the rocks into the soil and eventually new species of plants will start to grow on the land.

President Nixon resigned from the presidency because he had an argument with his advisors lost the support of the American peopl
Anarel [89]

: Rationale: A lack of support. It was discovered that Nixon’s advisors had connections to the individuals involved in the burglary at the democratic headquarters. Not long after, Nixon was forced to release transcripts of all his recorded conversations at the White House. Nixon complied, but did not turn over any of the recorded conversations with his advisors. He claimed that as president he had the right to keep discussions with his advisors private. As the case details were released through the media, Americans were shocked to learn that the President might be involved in criminal activity and withdrew their support.

¿Que impacto tiene los diferentes tipos de centrales eléctricas en nuestro medio ambiente?​
Fofino [41]

Answer:

Sin los correspondientes controles y marcos regulatorios, las centrales eléctricas pueden tener efectos adversos sobre el medio ambiente y contaminar los ecosistemas naturales, representando un serio riesgo para la salud humana

Explanation:

Las centrales eléctricas representan un riesgo latente para el medio ambiente, con lo cual ellas deben estar bajo un estricto marco regulatorio y control por parte de las instituciones gubernamentales especializadas para tal fin. Por ejemplo, las centrales hidroeléctricas generan la inundación permanente de grandes áreas (incluso miles de hectáreas) con el objetivo de aumentar la capacidad de generación de energía eléctrica. Por otra parte, se cree que aproximadamente el 50% de la polución industrial se debe a la acción de centrales eléctricas convencionales, las cuales utilizan la combustión del carbón, el petróleo o el gas natural con el objetivo de generar energía eléctrica. Este tipo de centrales eléctricas producen dióxido de carbono (CO2), el principal gas de efecto invernadero y considerablemente deterioran la calidad del aire que respiramos mediante la liberación de partículas contaminantes, presentando efectos adversos tanto para la salud humana como para el medio ambiente. Finalmente, la instalación de centrales eléctricas a base de la energía nuclear no generan gases causantes del efecto invernadero, pero pueden representar un serio riesgo debido a la posibilidad de liberación de materiales radiactivos durante accidentes nucleares, los cuales son capaces de contaminar permanentemente el medio ambiente. En este punto, es importante aclarar que los riesgos de accidentes en centrales nucleares se ha reducido notablemente en las últimas décadas y, por lo tanto, este tipo de centrales eléctricas se consideran relativamente seguras.

Question 25 (BRAINLIEST+20 points PLEASE I COULD REALLY USE SOME HELP)
siniylev [52]

Ans. 25.

Messenger RNA or mRNA has genetic information in the form of triplet codes, called as codons. These codons are made up of three nucleotide bases and each codon codes for a specific amino acid during protein synthesis.

According to codon chart, GCU codes for alanine (Ala), AAU codes for asparagine (Asn), and GUC codes for valine (Val). Thus, the amino acid sequence for the mRNA strand GCU - AAU - GUC is Ala-Asn-Val.

Ans. 26.

a). There are a total of sixty-four codons, made up of combinations of four nucleotide bases (4 X 4 X 4= 64). Out of sixty four codons, sixty one codons code for twenty amino acids that make proteins, while three codons (UAG, UGA, UAA) do not code for any amino acid and act as stop codons. Thus, no protein will be form with the mRNA strand UAG-UGA-UAA.

b). The UAG, UGA, and UAA are stop codons that act as signals to terminate the translation during protein synthesis. Thus, if a ribosome reads the mRNA sequence UAG, UGA, and UAA during translation, it will lead to termination of protein synthesis.
