Mientras se calienta una solución en un vaso de precipitados, ¿cuál es el
equipo de seguridad apropiado para tener en el banco?

Answers

Answer 1

Answer:

Fire extinguisher.

Explanation:

Fire extinguisher is the appropriate safety equipment to have at the side of the baker while heating a solution in a beaker because sometimes the solution catch heat due to reactions with flammable liquids which leads to big incident so in this case fire extinguisher can avoid such type of incident by turn off the heat due to the gas present inside the container of fire extinguisher so this safety equipment is necessary at the side of the reaction.

How could the aquifer around the Los Angeles are in California be susceptible to an impact by a Tragedy of the Commons?

Answers

Answer:

Due to over-pumping of water.

Explanation:

The aquifer around the Los Angeles are in California could be susceptible to an impact by a Tragedy of the Commons because the people used more water than the aquifer receives. The excess use of water from the aquifer through the well causes depletion of water which results in the shortage of water to fulfill the needs of existing population so it is wise to use water efficiently and used lower or equal water the aquifer receives in order to maintain level of aquifer.

How did the insertion of a nucleotide in a DNA sequence result in a phenotypic change in an organism

Answers

Answer:

if the nucleotide insertion occurs within the coding region of a gene (frameshift mutation), then it will change the open reading frame (ORF) of the resulting protein and thus also will alter the phenotype of the individual  

Explanation:

A mutation is any change in the DNA sequence of the genome of a cell/organism. A point mutation is a genetic mutation where a single nucleotide is inserted, deleted or changed from the original DNA sequence. The insertion of a single nucleotide in the coding region of a gene is called frameshift mutation since this nucleotide base shifts the way the DNA sequence is read. A frameshift mutation changes the meaning of the codons that follow the inserted nucleotide base and thereby protein function is generally lost, thereby also affecting the resulting phenotype associated with this protein.

What is the ultimate role of ecological succession in an environment

Answers

Answer:

The stable, end stage of ecological succession in which the plants and animals of a community use resources efficiently and balance is maintained by disturbances such as fire. The ultimate goal of ecological succession. After a natural disaster and continues until a climax community is reached.

Explanation:

The ultimate role of ecological succession in an environment is to reach the equilibrium in an ecosystem.

What is Ecological Succession?

This event involve in the steady and gradual change in a species of a given area with respect to the changing environment is called as ecological succession.

The changes are inevitable process where all biotic components of the ecosystem keep up with the changes in our environment.

This process ultimately reach equilibrium in the ecosystem and the community that achieves this referred as a climax community, where some species increase in number and others decrease.

The communities that undergo changes sequentially in an area is called sere, so it is also called as seral stage or seral community.

Evolution has taken place simultaneously with that of ecological succession, so all the communities we observe are the result of ecological succession.

Answer:

The correct answer is - A. 25%.

Explanation:

In humans, the blood group system is known as the ABO system where blood groups A and B are codominant and O blood group is recessive. The genotype of the A blood group could be AA or AO similarly for the B blood group genotype would be BB or BO, for the O blood group OO whereas for the AB blood group both A and B alleles should be present together.

Cross: AB blood type father with an A blood type mother (genotype AO)

Gametes: A, B and A, O

Answer:

Los alimentos son nuestro combustible y sus nutrientes proporcionan a las células del cuerpo la energía y las sustancias que necesitan para funcionar. Pero, antes de que los alimentos puedan hacer eso, los debemos digerir, descomponiéndolos en trozos pequeños para que nuestros cuerpos los puedan absorber y aprovechar.

El primer paso del proceso digestivo tiene lugar antes de que ni tan siquiera probemos la comida. Con solo oler una tarta de manzana casera o pensar en lo delicioso que va a saber un tomate maduro, empezamos a salivar, y el proceso digestivo se inicia preparándonos para ese primer bocado.

Casi todos los animales tienen un sistema digestivo en forma de tubo, donde los alimentos:

entran por la boca

pasan por un largo tubo

salen del cuerpo en forma de heces (caca) a través del ano

A lo largo del camino, se descomponen en moléculas diminutas para que el cuerpo pueda absorber los nutrientes que necesita:

Las proteínas se deben descomponer en aminoácidos.

Los almidones se descomponen en azúcares simples.

Las grasas se descomponen en ácidos grasos y glicerol.

Los residuos que el cuerpo no puede aprovechar son los que salen del cuerpo en forma de heces.

Explanation:

Look at the diagram below. It shows two solutions separated by a partially permeable membrane. Which number arrow shows the direction in which water molecules will move?

Answers

Answer:

Arrow no. 4

Explanation:

Water flows from a region of higher concentration to a region of lower concentration, i.e, osmosis.

Dilute solution means it has relatively less solute and more solvent, meaning more amount of water.

And just the opposite for concentrated solution.

So since the dilute solution has more water and concentrated solution has less, and water moves from a region of higher concentration to a region of lower concentration, option 4 is the correct answer.

During the osmosis process solvent is moved from a lower solute concentration to a higher solute concentration, hence arrow 4 defines the movement of water molecules.

What is osmosis?

Osmosis is the process through which solvents move from a region of lower solute concentration to one of higher solute concentration across a semi-permeable membrane.

Water in the cell acts as a solvent and moves from lower solute concentration to higher solute concentration through a partially permeable membrane.

Conversely, in diffusion, molecules migrate from an area of greater concentration to regions of lower concentration without the need for a semi-permeable barrier.

Therefore diffusion of water molecules in the osmosis process from low solute concentration to high solute concentration, hence arrow 4 defines the movement of water molecules.

Mad cow disease is caused by deformed proteins called prions. The disease is spread when meat from an infected cow is eaten. Prions can make normal proteins deform into more prions. After a few years, the brain of an infected person or cow looks like a sponge full of holes. Are prions considered organisms?

Answers

Answer:

No.

Explanation:

No, prions are not considered organisms because they are proteins that the infection to the surrounding cells and tissue. Prion is a type of protein that can change normal proteins in the brain into abnormal. Prion diseases can affect both humans and animals and spread to humans by eating infected meat products. So we can conclude that prions are not organisms, they are proteins.

Alcon blue butterflies spend the first part of their lives as caterpillars that live with Myrmica ants. When a caterpillar lives with the ants, it pretends to be a Queen ant by making noises that make it sound like the Queen ant. Queen ants receive more food and better protection than any other ants in the nest. When the caterpillar mimics a Queen ant, the ants feed and protect the caterpillar instead of other ants in the nest. Which word best describes the relationship between the caterpillar and ants

Answers

Answer:

The correct answer is - parasitic.

Explanation:

The Maculinea Alcon butterfly has a unique relationship with species of Myrmica ants. The butterfly's caterpillars picked up by passing Myrmica ants, and take to their nests where this caterpillar makes sounds like the queen ants, and to this sound, all ants protect and feed this caterpillar instead of other ants.

Normally there is a mutualistic relationship between ants and caterpillars but in the case of The Maculinea Alcon caterpillar and Myrmica ants, there is a parasitic relationship.
