El agua es un elemento relativamente escaso y por lo tanto debe ser cuidadosamente utilizado. En América Latina la distribución de las precipitaciones hace que la disponibilidad de este recurso sea desigual dentro de la región, siendo por lo tanto especialmente importante cuidarlo a fin de evitar el agravamiento de la escasez de agua potable.
El agua es fundamental para la vida ya que este elemento cumple muchas funciones dentro de los sistemas biológicos las cuales incluyen, entre otras:es un sustrato imprescindible de muchas reacciones químicas que se producen dentro de la célulaayuda a la digestión de alimentosmantiene la temperatura corporal dentro del rango aceptable para la vida, etc.El agua potable (apta para consumo) es también fundamental para evitar la aparición y propagación de enfermedades tales como diarrea, cólera, fiebre tifoidea, poliomielitis, etc.De acuerdo al Informe Anual del Servicio de Aguas de Lima, aproximadamente el 93% de la población peruana posee servicio de agua potable.América Latina posee aproximadamente el 25-30% de los recursos hídricos del planeta; sin embargo, su distribución dentro de la región es desigual, con áreas totalmente desertificadas y otras que actualmente sufren inundaciones periódicas. Esta situación se encuentra agravada por las consecuencias del cambio climático, las cuales generan una mayor inestabilidad en la distribución y estacionalidad de las precipitaciones.El cuidado de la cantidad y calidad del agua disponible es fundamental para mantener la biodiversidad de las especies alrededor del planeta y asegurar nuestra salud, como así también para garantizar la vida de las generaciones venideras.La ONU (Organización de Naciones Unidas) posee un programa cuyo objetivo principal es reforzar la coordinación entre diferentes países y así lograr el acceso generalizado de las poblaciones al agua potable, como así también lograr su uso responsable.Algunos tips útiles relacionados al cuidado del agua son:Cerrar la canilla al lavar utensilios de cocinaEvitar la pérdida constante de agua en la grifería del hogarEvitar el uso excesivo de agua al ducharseCerrar la canilla al lavarse los dientesAprende más sobre este tema en:

Fire reproduces if a spark from the original fire as it lands on another object. is it evidence or reasoning?
Answer:
reasoning
Explanation:
Fire reproduces if a spark from the original fire as it lands on another object is reasoning.
What is the reasoning?Reasoning is the ability or process of thinking and process thing in a logical and factual way. The use of a reason for a situation is reasoning and it is a sensible way of thinking.
Fire needs oxygen to spark up and fire up. When there are good ventilation and fire breaks up and burns with full light and heat. If the spark of fire burns other objects, it also burned up due to fire. This is the proper and factual reason for burning a fire.
Evidence is when given some evidence for the given statement but in the statement, the evidence is not given, just a reason is given for the burning of fire.
Thus, the given statement about fire is reasoning.

Scientists have determined that the pH of seawater can’t physically drop below approximately 7.9 because of its chemical properties. For this reason, some people argue that the term “ocean acidification” is not quite accurate. Do you agree? Explain your reasoning using the pH scale and these graphs showing the acidity trends in Bermuda, Hawaii, and the Canary Islands.
Answer:
The word acidification can be misleading because a pH of 7.9 is still considered slightly alkaline. However, as the graphs in these three locations show, as CO2 rises, the pH drops, moving in the direction of the acidic end of the pH scale.
Explanation:
“Ocean acidification” is occurs in various parts of the world.
I don't agree with the statement that “ocean acidification” is not quite accurate because it happened due to more release of carbondioxide gas in the atmosphere which is dissolved in the ocean or sea water.
When the carbondioxide gas dissolved in water, it produces carbonic acid which definitely changes the pH of the ocean water tends to acidic so in my opinion ocean acidification occurs in various parts of the world.

Complete a dichotomous key for the 10 leaves on the common leaves sheet
A dichotomous key might be considered a significantly useful tool to classify organisms. The key provides an easy and fast way for identification by describing different morphological traits, leading you to the correct taxonomic classification.
When you have an organism -or part of it-, and you need to identify it taxonomically, you use a dichotomous key. The key provides morphological descriptions about different taxonomic groups in an easy way to identify these traits in your individual.
It is simple to read a dichotomous key. The term dichotomous refers to how information is provided. You will always have two options (a and b, or 1 and 2), and you will have to choose one of them according to the characteristics of your organism. The key describes specific morphological traits of organisms that are useful for differentiation.
Probably you might need an atlas or a dictionary to understand some of the technical terminologies. You will also need to carefully observe your specimen, to get to distinguish different traits. If the specimen is too small you might need a loup.
Let us analyze simple example using a group of 5 organisms. Let us assume that you do not know their names, and you need to know what is the individual in the red circle (You will find it in the attached files).
Dichotomous key
Statement 1a ----------- The organism is a vertebrate ----------- Frog
Statement 1b------------ The organism is invertebrate ----------- Go to 2
Statement 2a ---------- The organism has a multisegmented
and elongated body, with too many ----- centipede
legs.
Statement 2b ---------- The organism has a relatively short body
and with fewer legs ------------------------------ Go to 3
Statement 3a ----------- The organism has 8 legs ----------------------- Spider
Statement 3b ----------- The organism has 6 legs ----------------------- Ant
As you can see, this a very simple example, but ilustrates how the key provides enough information for you to reah the correct option.

Answer:
The correct answer to your question is D
Based on this information, the substances will move directly across the membrane from inside the cell to outside the cell (D).
What is simple diffusion?It is a diffusion process through the membrane that consists of the passage of a substance through the biological membrane as a function of the concentration gradient.
Molecules and ions can cross the membrane passing from the area of higher concentration to the area of lower concentration.
Therefore, we can conclude that based on this information, the substances will move directly across the membrane from inside the cell to outside the cell (D).
