Answer:
MUTATION
Explanation:
Mutation is a change or alteration in the genetic sequence of a DNA or RNA (nucleic acid) that are induced by a chemical substance called MUTAGEN or by a spontaneous occurrence. Mutation are of different types depending on how it occurs in the cell. A mutation can be deletion (removal), substitution (replacement), insertion (addition) etc.
Based on this question that states that "any change in the sequence of bases in DNA or RNA that can be caused by mutagen or can happen spontaneously in the cell", the process of MUTATION is being described.

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.

vague repetitive pictures
Answer:
Should be C
Explanation:
D is wrong because standing out should mean they are spotted more easily, which means they get hunted down more often/ prey spot them easier
B is kind of weird because larger population = more competition, and I remember owls work alone
A is suspicious because they are both tawny owls and I don't understand how less food they need to be significant
C sounds plausible because the gray feather can be a "stronger" gene or something

How does a Cell Grow?
When a Cell growth is not to be confused with cell division or the cell cycle, which are distinct processes but they can occur alongside cell growth during the process of cell proliferation,
whereas a cell, it is known as the "mother cell", Also, when grows and divides to produce two " daughter cells ".
Therefore, The correct option is 'D'. The cell divides into two cells creating more space for materials.

Is the Great Green Wall an example of Secondary Succession?
Answer:
The Great Green Wall is taking root in Africa's Sahel region, at the southern edge of the Sahara desert. The Great Green Wall is a symbol of hope in the face of one of the biggest challenges of our time - desertification. This game changing African-led initiative aims to restore Africa's degraded landscapes and transform millions of lives in one of the world's poorest regions, the Sahel.
Primary succession occurs on land where no previous growth has taken place and there is no substrate/soil. Secondary succession occurs on land where there has been previous growth, the soil and seed bank makes up the substrate.

Describe how proteins form (polypeptide)
Answer: Atoms were created after the Big Bang 13.7 billion years ago. As the hot, dense new universe cooled, conditions became suitable for quarks and electrons to form. Quarks came together to form protons and neutrons, and these particles combined into nuclei.
Answer:
Within a protein, multiple amino acids are linked together by peptide bonds, thereby forming a long chain. Peptide bonds are formed by a biochemical reaction that extracts a water molecule as it joins the amino group of one amino acid to the carboxyl group of a neighboring amino acid.
