En que consisten las siguientes interacciones bioticas de las relaciones entre organismos: DEPREDACION, PARASITISMO, MUTUALISMO, COOPERACION, SIMBIOSIS, COMPETENCIA, COMENSALISMO, AMENSALISMO

Answers

Answer:

La depredación implica la interacción entre un depredador y una presa. El parasitismo ocurre entre 2 organismos diferentes donde un parásito se alimenta del huésped hasta que el huésped es destruido, el mutualismo ocurre es una forma de relación donde ambos organismos de diferentes especies se benefician. La cooperación se produce cuando los organismos trabajan juntos como un equipo para lograr objetivos comunes, como derribar a un gran depredador. En la simbiosis ocurre en diferentes organismos donde ambos se benefician o uno se beneficia o ninguno se beneficia a medida que interactúan. La competencia es la capacidad de un organismo para prosperar en entornos difíciles. El comensalismo es un tipo de relación que ocurre entre organismos donde uno se beneficia y el otro no se ve perjudicado. El amensalismo ocurre entre diferentes especies de organismos en una relación donde uno es destruido y el otro prospera.

Explanation:

 

La depredación ocurre en la cadena alimentaria donde los organismos más pequeños son consumidos por los más grandes en la cadena alimentaria. El depredador no puede sobrevivir si hay una reducción en la población de presas. Un ejemplo se ve en un león y un ciervo. En el parasitismo, el parásito solo puede sobrevivir cuando el huésped está vivo. Una vez que el huésped muere, el parásito muere con él. El parásito deriva todo su sustento del huésped hasta que el huésped es destruido. Ejemplo de garrapatas en perros. En mutualismo, ambos organismos de diferentes especies en relación obtienen los mismos beneficios. Un ejemplo es el del pájaro picador y la cebra, donde el pájaro picador obtiene su alimento de la cebra y la cebra controla sus plagas. La cooperación se produce entre las mismas especies que trabajan juntas para derribar presas más grandes. Se observa un ejemplo entre las hormigas que derriban una cucaracha. En el caso de la simbiosis, podría ser uno de los 4 tipos: comensalismo, mutualismo, parasitismo o endo / ectosimbiosis. Aquí los organismos de diferentes especies trabajan para lograr objetivos divergentes que a veces se ayudan mutuamente y otras veces se daña. La competencia se ve cuando un organismo posee características especiales que lo ayudan a sobrevivir en ambientes hostiles. Por ejemplo, algunas bacterias poseen cápsulas que les ayudan a almacenar alimentos y sobrevivir largos períodos de deshidratación, así como la presencia de determinantes de resistencia a los antibióticos que pueden ayudarlos a sobrevivir a un ataque de antibióticos. En el comensalismo, una especie vive de otra, pero la otra no sufre daños. Un ejemplo típico son las aves que viven en huecos de árboles. En el amensalismo, la presencia de una especie de organismo inhibe el crecimiento de otro. Un ejemplo es el de las malas hierbas en una granja de maíz. Las malas hierbas ahogan la planta hasta que se destruye para que puedan prosperar.

which statement provides the best argument against making major changes to the atmosphere to help protect Earth's resources​

Answers

Answer:

The options are

A. There will be less soil and dust in the air as construction increases.

B. The atmosphere will improve as more people move to large cities.

C. Making major changes to the atmosphere can be a costly process.

D. It is more important to protect land and water resources than the atmosphere.

The answer is C. Making major changes to the atmosphere can be a costly process.

Explanation:

Making major changes to the atmosphere to the atmosphere to help protect Earth's resources​ is costly because no one knows the effects of what the changes will have when effected. Another angle is effecting the changes will be a very expensive one as the atmosphere is very large and will be difficult having it happen.

This however validates making major changes to the atmosphere can be a costly process as the right option.

A colorimeter is an instrument used for chemical analysis by comparing a liquid’s color with standard colors. In an experiment, a scientist used two colorimeters and noted the readings. The first colorimeter showed consistent readings that were five points lower than the actual reading. The second colorimeter provided readings that were the same as the actual reading. Which two statements are implications of these readings?


1). The first colorimeter is reliable but not valid.


2). The second colorimeter is valid and reliable.


3). Both the colorimeters are reliable and valid.


4). The readings of the first colorimeter can be used without repeating the experiment.


5). The readings of the second colorimeter aren’t reliable and can’t be used for the experiment.

Answers

Answer:

The correct answers are option A and B

Explanation:

The first colorimeter is reliable because the the reading it is showing is same for all the times the experiment is done. Though the result obtained is wrong but it is reliable.

The second colorimeter is valid and reliable because it is showing the correct results again and again. This is valid result as it is giving the result same as that of actual readings.

A high concentration of toxic chemicals is present in the bodies of animals at the highest trophic levels.


arrowBoth

Answers

Answer:

The question is incomplete, the missing part i.e. the environmental change is:

(A) biomagnification

(B) acid rain

(C) eutrophication

The answers are:

1. Acid rain- Chemicals react with water and oxygen that enter water systems.

2. Eutrophication- Nutrients in excessive amounts enter water systems, causing algal bloom.

3. Biomagnification- A high concentration of toxic chemicals is present in the bodies of animals at the highest trophic levels

Explanation:

1. Acid rain is an environmental disorder in which rainfall becomes acidic due to pollution. The pollution is as a result of the release of gaseous chemicals e.g sulfur, nitrogen oxide, which are produced by industries, into the atmosphere. These chemicals then react with water in the atmosphere to form acidic solutions, which then falls back as rain. Hence, chemicals reacting with water and oxygen that enter water systems describes ACID RAIN.

2. Eutrophication is the pollution of water bodies with substances containing chemicals like nitrogen, phosphorus etc. The chemicals, which are in excess, serve as nutrients to algae, which uses them to grow excessively forming a bloom called ALGA BLOOM. Hence, nutrients in excessive amounts entering water systems, causing algal bloom describes EUTROPHICATION.

3. Biomagnification refers to the build up or accumulation of toxic chemical substances in the body systems of living organisms higher up in the food chain. Pollutants like pesticides, herbicides flow into water bodies and are absorbed by certain aquatic organisms. When these organisms are fed on by consumers, the harmful substances accumulates in their tissues until it reaches a maximum concentration. Hence, a high concentration of toxic chemicals present in the bodies of animals at the highest trophic levels describes BIOMAGNIFICATION.

Answer:

1. Acid rain- Chemicals react with water and oxygen that enter water systems.

2. Eutrophication- Nutrients in excessive amounts enter water systems, causing algal bloom.

3. Biomagnification- A high concentration of toxic chemicals is present in the bodies of anima

C. The baby is prokaryotic
D. The baby is male

Answers

Answer: d) the baby is male

Explanation: Ovules contain X chromosomes whereas sperms come in two types: one type contains x chromosome and the other contains Y chromosome.

When a sperm containing X chromosome fertilises with an ova, the zygote will have two X chromosomes. This zygote would develop into a female child. When a sperm containing Y chromosome fertilises with an ova, the zygote will have one X and one Y chromosome. This zygote would develop into a male child.

How is the cytokinesis of plant cell different from the animal cell during mitosis?​

Answers

Answer:

a plant cell has a rigid cell wall however an animal cell does not. (more info below)

Explanation:

Because a plant cells are surrounded by the rigid cell wall, it cannot use microfilaments to go through cytokinesis. Instead, it builds a cell plate in the middle of the cell to represent the division. An animal cell does not have this rigid structure, so it forms a cleavage furrow by pinching the cell in the middle with microfilaments. This will successfully divide the cell into two.

hooe this helped!

Answer:

Cytokinesis is the final stage of cell division in eukaryotes as well as prokaryotes.  In animal cells, the plasma membrane of the parent cell pinches inward along the cell's equator until two daughter cells form.  In plant cells, a cell plate forms along the equator of the parent cell.
