How often should observations be made in a simulation of natural selection??

Answers

Answer 1

Answer:

A minimum of 3 observations will produce reproducible results

Explanation:

Often, when simulations are carried out to observe for natural selection, it will be safe to conduct >3 observations to reduce the likelihood of errors. Errors could affect the reproducibility of the results which researchers will not want to compromise. The models ( for example the physical natural selection simulation or the virtual natural selection simulation methods) that are used provide for more observations to be made to ensure more accurate results and interpretations are obtained.

what is reflex action?

Answers

Reflex action is the response to a stimulus. The spinal cord along with the brain stem is responsible for the reflex movement.
For example : when you touch a hot object you immediately remove your hand from it
reflex is made possible by neural pathways called reflex arcs which can act on an impulse before that impulse reaches the brain.

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.

Consider these three scientific statements
1. The inherited traits of plant, animal, and microbial populations change through time because of differential reproductive success patterns, which are influenced by the way individual organisms interact with their environment.
2. If a certain culture of bacteria is subjected to more ultraviolet radiation than another culture, Then it's reproductive success rate will be reduced.
3. In sexual reproduction, Recessive alleles are always masked by dominant alleles. in other words, the traits of a Recessive allele will not be expressed if a dominant allele is present.
These statements have a lot in common. Each statement is testable, each describes a potential realishionship between observable factors, and each deals with a different aspect of reproduction or inheritance. However, one of the statements is typical of a scientific hypothesis, one is typical of a scientific theory, and one is typical of a scientific law.
Which statement is a hypothesis, which is a theory, and which is a law? "Justify your anwsers"​

Answers

Answer: 1. Scientific theory

2. Scientific hypothesis

3. Scientific law

Explanation:

The scientific theory can be defined as the aspects of the natural world that are tested and proofed by the scientific methods, involving the observations, measurements and evaluation of the outcome. The scientific theory can be changed with new ideas or evidences. The first statement is a scientific theory because the microbial population may change due to the fact that how microbes interact rather than restricting to the differential reproductive success.

The scientific hypothesis can be defined as the statement that is required to be tested or verified by scientific method. It is based on presumption. The second statement is the example of scientific hypothesis because it is beginning with "if" here it is presumed that if the culture is exposed to ultraviolet radiation then reproductive success rate will be reduced.

The scientific law is based upon facts or evidences obtain after experimental trails or applying the scientific methodology. This cannot be changed with time. The third statement is the Mendel's law of dominance.

The universe can be explored using visible and invisible forms of light. These dishes (that detect radio waves from outer space) are part of a much bigger telescope in New Mexico. What is its name? A. Viking B. Voyager C. Very Large Array D. International Space Station

Answers

Answer: C. Very Large Array

There are 28 radio antenna, which are essentially satellite dishes. Only 27 are in operation at any given time, leaving one to sit out for maintenance. Astronomers using this array were able to observe black holes, and also observe the formation of interplanetary disks, among many other applications as well.

The reason why so many dishes are used is to increase the faint signal that is received from such a long distance away (often lightyears away). The 27 dishes are effectively the same as having a single radio dish that is 36 km (22 miles) in diameter. Having such a impossibly massive satellite dish is not feasible, so it's more practical to go with 27 smaller dishes.

how has paraquat stopped the algae from making atp nadph and sugars

Answers

Answer:

This is by disrupting the mechanisms of photosynthesis.Paraquat is an herbicide. A photosynthesis inhibiting herbicides. In the light dependent reaction, It acts  as oxidizing agent  by accepting electrons  from Photo system I. and lose these electrons to oxygen molecules which becomes oxidized.

Therefore, disrupting the electron transport chain.With the electron transport chain disrupted, PMF is inhibited, electrochemical gradients for generating energy for ATPs synthesis, by ATPase synthase enzyme is blocked.

Therefore, ATPs synthesis is prevented. With this, Calvin Cycle is blocked, so no CHO id formed. With lack of electron transport chain, NADPH will not be formed. .

The feature of cell theory that is best demonstrated in the image is organisms are made up of a large number of cells. Thus, the correct option for this question is D.

What is Cell theory?

The cell theory was proposed by two famous scientists. i.e. M.J. Schleiden and T. Schwann. There are three assumptions that fall under the cell theory.

All living organisms whether plants or animals are made up of cells.A cell is the smallest unit of all living organisms.It is the basic structural and functional unit of life.

Cell theory was further refined by German biologist Rudolf Virchow in 1855. According to him, all cells are arising from pre-existing cells.

According to the three assumptions given above, the one which is best demonstrated by the image is that Organisms are made up of a large number of cells.
