When you weigh ammonia, what fraction of it is hydrogen?Answer Options:A. 3/17B. 3/4​

Answers

Answer 1

Hydrogen and nitrogen, which are both nonmetals, are found in ammonia. With the three hydrogens present, nitrogen thus forms three covalent bonds.

Ammonia consists of three hydrogen atoms and one nitrogen atom. Hydrogen nitride is another name for it. Ammonia therefore contains nitrogen and hydrogen in a 14:3 mass ratio. Hydrogen and nitrogen, which are both nonmetals, are found in ammonia. With the three hydrogens present, nitrogen thus forms three covalent bonds.

In ammonia, the bond with a proton (H +) is formed by the lone electron pair on the nitrogen atom (N), which is depicted as a line above the N. After that, each of the four N–H bonds, which are polar covalent bonds, is equivalent. The ion isoelectronic with methane and the borohydride anion and has a tetrahedral structure.

Answer 2

When I weigh ammonia, fraction of hydrogen is A)3/17.So,correct option is A. Molecular formula of ammonia is NH₃.

For finding the fraction of hydrogen in ammonia, we need to know about the molecular mass of ammonia. By knowing the molecular mass we can easily find the fraction of hydrogen in it.

We know that molecular mass of ammonia is =Molecular mass of Nitrogen + 3 ˣ Molecular mass of Hydrogen. Since, molecular mass of hydrogen is 1 gm and molecular mass  of nitrogen is 14g.

So, molecular mass of ammonia is = (3 ˣ 1) + 14

=>molecular mass of ammonia is =17g.

Now,taking about fraction of hydrogen in it=(total mass of hydrogen) / total mass of ammonia

=>Fraction is =3/17

Hence,correct option is A.

Why are stabilizing proteins neeed to keep the DNA strands separated?

Answers

Single-stranded DNA-binding proteins (e.g., eukaryotic replication factor A [RFA]) then stabilize the unwound template DNA, keeping it in an extended single-stranded state so that it can be copied by the polymerase.

Single-stranded DNA-binding proteins are protected exactly tightly to DNA, but with extremely little carefulness for individual nucleotide sequences.

What is DNA?

They accomplish this by interacting strongly with the DNA backbone, via hydrogen bonds with the ribose and phosphates and complementary control interactions with the phosphates.

When the Proteins of DNA Replication DNA Helicases. These proteins attach to the double-stranded DNA and facilitate the separation of the two strands. DNA single-stranded critical proteins.

Although, These proteins bind to the DNA as a stable tetramer the single-stranded structure is produced by the action of the helicases.

Answers

The process which would occur in the body of a type 1 diabetic after they consume a carbohydrate-heavy meal is:

The digestive system tries to break down the complex sugars which increases the blood sugar level which leads to the production of insulin to maintain the blood sugar level throughout the body.

A Type 1 diabetic person is one who has been diagnosed with the level  of diabetes, where the pancreas does not produce enough insulin to control the sugar levels of the body.

With this in mind, when such person consumes a high carbohydrate meal, it means that he has ingested complex sugars which would be difficult  for the digestive system to break down which would overwork the pancreas, but as there is little or no insulin production, then there would likely be health complications.

A que se denomina metaboismo? Diferenca anabolismo de catabolimo da 4 ejemplos diferencia reaccion endegonica de exergonica

Answers

Answer and Explanation:

Metabolismo: El término hace referencia a todos los cambios y las reacciones quimicas y biológicas que ocurren en cada célula del organismo y que resultas escenciales para el funcionamiento adecuado del organismo (una buena nutrición, crecimiento, reparación celular, conversion energética, etc.).

Estas reacciones ocurren a lo largo de toda la vida del organismo. Cada celula toma sustancias que luego modifica químicamente para integrarlas como nuevos componentes celulares. Algunos de estos componentes son utilizados en reacciones como la respiración celular.

El metabolismo puede ser dividido en anabolismo y en catabolismo. Durante el anabolismo suceden reacciones que consumen energía (ATP) para sintetizar moléculas complejas a partir de moléculas simples, y que son necesarias para el funcionamiento del organismo. Mientras que durante el catabolismo suceden reacciones que liberan energía al deegradar o reducir moléculas grandes en otras mas simples, para que el cuerpo pueda asimilarlas y las transforme en energia (ATP). Esta energía luego será utilizada en los procesos anabólicos.

Ejemplos:

- Respiración celular: Degradación de molécula del glucosa para liberar y obtener energía y consecuentemente, moleculas mas simples (CATABOLISMO)

- Ciclo de Krebs: Oxidación de la molécula acetil-CoA y obtención de energía en forma de ATP (CATABOLISMO).

- Digestión: Degradación del alimento para obtener elementos mas asimilables por la célula y energía (CATABOLISMO).

- Degradación de ADN y ARN (CATABOLISMO).

- Fotosíntesis: Transformación de compuestos inorgánicos en orgánicos utilizando energía solar (ANABOLISMO).

- Síntesis proteica: Utiliza aminoácidos y energía para formar proteinas necesarias para el organismo (ANABOLISMO).

- Ciclo de Calvin: Usa moléculas de CO2 para formar glucosa (ANABOLISMO).

- Gluconeogénesis: Síntesis de glucosa a partir de precursores diferentes a los  glúcidos (ANABOLISMO).

Reacción excergónica: reacción espontánea que se lleva a cabo y donde se produce la liberación de energía. No necesita energía para suceder.Reacción endergónica: reacción no espontánea. Necesita energía para suceder. Ocurren reacciones celulares a partir del consumo de energía.

Please Helppp!!! What could lead to different populations of the same species living in different environments?

Answers

Answer: Migration, because species move to other places for food or a better or more suitable habitat and sometimes their is other species there.

Different ecological and biogeographical causes lead to different populations of the same species living in different environments. Ecological factors include intraspecific competition, migration, resource searching, habitat destruction, among others. Biogeographical dispersion involves wider areas and time factor. Human action is also a cause of dispersion.

-----------------------------------

Dispersion can be defined as the dissemination and distancing process of some individuals from others. It refers to the change in an organism's range or distribution area.

Different ecological and biogeographical processes might be involved in organisms' dispersion.

Ecological processes involve intraspecific competition for resources, habitat destruction, lack of resources -food or water-, among others. This is an intra-area, moderate dispersion that reduces competition and increases niche findings. It involves daily and seasonal migration and territoriality. Biogeographical processes refer to bigger changes that involve wider areas and time. It includes the historical factor, besides migration. This is an extra-area dispersion process.

            → Jumping dispersion refers to a few individuals, in a short time, that  can cross a barrier and occupy a new area. In this situation, the establishment is not always for sure. They must reproduce and start a new population of a certain size that can survive the new conditions.

            → Diffusion refers to populations that, through many generations, explores and expands in new regions with favorable conditions.

            → Secular migration is the diffusion through thousands of generations.

Dispersion is also caused by human actions, following different interests and goals.

When two populations of the same species migrate to new areas and adapt to different environmental pressures, they will probably suffer from the speciation process with time, becoming two different species.

You catch, tag, and release 35 fish back into a pond. Then, you catch 70 more fish, 12 of which have tags on them. What is the best estimate of the number of fish in the pond?

Answers

Answer:

204

Explanation:

The estimated total number of individuals in a population using the capture and recapture method is given by the following equation;

N = (M x C)/R

where N = estimates of the number of individuals in the population, M = number of individuals captured and marked the first time, C = total number of individuals captured (marked and unmarked) in the second attempt, and R = number of marked individuals captured in the second attempt.

In this case, M = 35, C = 70, and R = 12

Hence,

N = 35 x 70/12 = 204.16

Therefore, the estimated number of fish in the pond is 204.
