D. Mountaintops are blown up to mine coal.

Answers

The correct answer is D

In an ecosystem, the statement which  describes one way that a nonrenewable energy resource is obtained is that mountaintops are blown up to mine coal.

What is an ecosystem?

Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

The noble gases in group 18 were some of the last natural elements to be discovered. Why do you think this is so?

Answers

Answer:

because they were extremely un-reactive. Being inert, they were difficult to isolate via chemical reactions, thus difficult to distinguish as separate elements

Explanation:

The noble gases of group 18 were the last to be discovered because they are highly unreactive or inert.

Noble gases refer to elements in group 18. These elements are renowned for being inert.

As a result of their inertness and because they are all gases, they are sometimes called "inert gases".

This chemical inertness made it difficult to discover these elements until lately. Many natural elements were discovered because they participate in chemical reactions. Hence, inert gases became the last natural elements to be discovered.

Biologists refer to the number of chromosomes with an "#n". For example, 1n for one copy of chromosomes and 2n for two copies. How else can this be expressed?

Answers

Answer:

haploid/diploid

Explanation:

The number of chromosomes can also be expressed as haploid or diploid, instead of 1n for one copy and 2n for two copies.

The haploid number of chromosomes also refers to a copy of the chromosomes or half of the genome of organisms while the diploid number of chromosomes refers to the double or complete set of chromosomes in the genome of organisms.

So, in other words: n = haploid and 2n - diploid.

plz give me brainlist :)

Answer:

Type A is a lens galaxy and Type B is an irregular galaxy.

Explanation:

Type A: Lens galaxies' have a large flattened core. lenticular galaxies have a shape reminiscent of a lens (hence the alternative name).

Type B: Irregular galaxies' do not have a regular shape. An irregular galaxy is a galaxy that does not have a distinct regular shape, unlike a spiral or an elliptical galaxy. Irregular galaxies do not fall into any of the regular classes of the Hubble sequence, and they are often chaotic in appearance, with neither a nuclear bulge nor any trace of spiral arm structure.

Answers

Answer:

The correct answer would be - plants, and small animals like moose, rodents, deer and others as bears are omnivorous animals.

Explanation:

In any forest ecosystem, mostly in the forest ecosystem, beers depend on various kinds of animals and plants for their nutrition and energy. They depend on plants that are rich in berries, fruits, and flesh roots. Beers also eat small animals such as rodents, fishes, and hoofed animals.

Therefore, an increase in the number of beers in any ecosystem will lead to  a decrease in the population of these organisms and their population including plants.

Which of these is not an example of how substances move within cells?​

Answers

Answer:

Diffusion

Explanation:

Diffusion is the process of transporting substances through the cell membrane. The cell membrane is semi permeable, which means it only allows certain substances to exit and enter the cell. Substances move from a high concentration to a lower concentration without the use of energy.

Cell cycle is not an example of how substances move within cells. Thus, option D is correct.

What is cell cycle?

A cell cycle is a series of events that takes place in a cell as it grows and divides. The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage).

Cell cycle is responsible for growth of cell not for the any substance movement within cell. Thus, option D is correct.

Your stomach pH is about 2. Would you expect starch
digestion to take place in the stomach?

Answers

Answer:

The correct answer would be - no or very less.

Explanation:

Digestion of the carbohydrates including starch begins within the mouth with the help of amylase into maltose. Most of the starch digestion takes place in the small intestine.

The significant digestion of starch does not take place in the stomach due to the acidity of the stomach as at low pH, amylase denatured or stay inactivated. Once the starch fragments reach the small intestines pancreatic amylase digest starch.

Answer:

Y is transcription, and Z is translation

Explanation:

DNA to mRNA is the process of transcription (think how DNA and mRNA both have nitrogenous bases, so to get mRNA from DNA you have to transcript-a written or printed version of material originally presented in another medium- it). mRNA to protein is the process of translation (think how mRNA and proteins are made from different building blocks, mRNA being from nitrogenous bases and proteins from amino acids, so it must be translated). Therefore, Y is transcription, and Z is translation.

En 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?

Answers

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).
