what do we call the actual gas or substance that causes air pollution?
Answer:
The actual gas that causes air pollution is called a pollutant
Explanation:
Air pollution is the decrease in air quality. Air pollutants are the gases that cause air pollution.
What are pollutants?Pollutants are harmful substances and particles that affect the quality of the environment and are man-made or natural. Fly ash from volcanic eruptions is a natural pollutant that deters the air quality.
The air pollutants like carbon monoxide, sulfur dioxide, and carbon dioxide released from the burning of fossil, coal, and vehicles alter the air quality and result in a change in weather conditions.
Therefore, the pollutants are the actual gases that cause air pollution.

What is reflex arc?A reflex arc is a neural pathway that mediates a reflex action. It is a rapid and automatic response to a specific stimulus that does not require conscious thought or decision-making from the brain. When a sensory receptor in the body, such as the skin or muscles, is stimulated, a nerve impulse is transmitted to the spinal cord, where it is processed by an interneuron.
The interneuron then sends a signal through a motor neuron to the effector, such as a muscle, causing a rapid and involuntary response, such as pulling your hand away from a hot stove. This entire process occurs without conscious control from the brain, allowing for quick and protective responses to potentially harmful stimuli.

Think about a model that you can construct that could be used to show the difference in prokaryotic and eukaryotic cells. In 6 complete sentences(3 for each type of cell), explain the process you would use to construct the model and how you would use the model to explain the differences between prokaryotic and eukaryotic cells to your classmates.
Answer:
Prokaryotic cell-- no organelles, no membrane.
Eukaryotic cell -- Have organelles and membrane.
Explanation:
For the model of prokaryotic cell, we construct the model by removing organelles from the cell whereas in the eukaryotic cell, we add the organelles because in eukaryotic organisms, organelles are present in the cell that performs specific function. In the model of prokaryotic cell, we have to remove membrane around the nucleus whereas membrane president around the nucleus. In the prokaryotic cell, nucleus is not visible while on the other hand, in eukaryotic cell, the nucleus is visible and can be differentiate from other organelles.
Is this an accurate description of the water cycle?

What causes evolution to occur in organisms? Explain the process of evolution and how it is driven by various factors.
Answer:
Evolution occurs when these heritable differences become more common or rare in a population, either non-randomly through natural selection or randomly through genetic drift. This occurs because organisms with advantageous traits pass on more copies of these heritable traits to the next generation

Hi there!
The answer to this question, I believe, would be C, conducting an experiment. When you make your hypothesis, you have already stated your question, analyzed the data, and formed a logical assumption that you need to prove is true. Your hypothesis is your logical assumption; therefore, you ought to experiment and see if your assumption - your hypothesis - is correct.

Teniendo en cuenta problemáticas de la biología o de su aprendizaje ,pensar un tema investigar desde el enfoque cualita tivo y otro desde el enfoque cuantitativo
Answer:
Caso de estudio: El efecto de estresores ambientales sobre el comportamiento animal
- Ejemplo de un tipo de estudio cualitativo: la influencia de estresores ambientales (por ej. niveles anormales de dióxido de carbono atmosférico) sobre el comportamiento en ratones de laboratorio
- Ejemplo de un tipo de estudio cuantitativo: la influencia de estresores ambientales sobre los niveles de producción de hormonas asociadas a cambios comportamentales en ratones de laboratorio
Explanation:
Un enfoque cualitativo se caracteriza por el hecho de que la información obtenida durante dicho estudio se agrupa en categorías mutuamente excluyentes. En biología, los estudios de tipo cualitativo generalmente se caen dentro de la dicotomía observacional (es decir, presencia o ausencia del factor en estudio). En el ejemplo arriba citado, es posible obtener datos relacionados a uno o más determinado aspectos comportamentales en los individuos bajo estudio (por ejemplo, presencia o ausencia de signos de irritabilidad) en ratones sometidos a algún estresor ambiental (por ejemplo, niveles anormales de CO2 atmosférico). Por otra parte, en un enfoque cuantitativo, la información se recopila en intervalos obtenidos a partir de operaciones aritméticas (estadística paramétrica). En el ejemplo, los datos obtenidos pueden ser clasificados en intervalos referidos a los niveles hormonales. Esta información resulta útil para determinar si las diferencias en los niveles hormonales entre individuos que se encuentran en presencia del estresor ambiental son estadísticamente significativas respecto al grupo control (individuos desarrollados en un ambiente con niveles normales de CO2 atmosférico), y de este modo concluir si el estresor ambiental puede o no modificar variables comportamentales. Los estudios cualitativos permiten el uso de variables independientes las cuales son clasificadas como cualitativas (discretas).

Which ACTN3 genotype (RR, RX, or XX) would provide these Olympic marathon athletes with an advantage, and why?
Answer:
XX
Explanation:
ACTN3 genotype i.e. XX provides advantage to the Olympic marathon athletes because it strengthens the fiber of the muscles. This gene is also called the gene of speed. This ACTN3 gene has a great influence on the type of fiber that makes body muscles, and they are also linked to strength and endurance so we can conclude that this gene provides benefits to the Olympic marathon athletes by giving strength to the fiber of muscles.
ACTN3 genotype is the gene encoding for the actinin of the skeletal muscle fibres. XX of the ACTN3 genotype will be advantageous for marathon athletes.
What is ACTN3 genotype and XX?ACTN3 genotype is the gene encoding for the protein of the skeletal muscles fibres that are associated with muscular performance. This protein is expressed in the myofibers with a high twitching ability and result in a high-velocity force.
The XX genotype provides strength to the muscles and is the gene coding for the proteins that give speed. They are also responsible for endurance and are beneficial for athletes.
Therefore, XX of the ACTN3 genotype is advantageous for athletes.
