Which statement about scientific hypotheses is true?
A. Hypotheses should be made after the investigation is completed.
B. If hypotheses are not supported, the experimental results are still useful.
The statement which is true about scientific hypotheses is as follows:
If hypotheses are not supported, the experimental results are still useful.Thus, the correct option for this question is B.
What is a Scientific hypothesis?A Scientific hypothesis may be defined as a proclamation or group of information which is mandated to be experimented with by utilizing an investigation procedure.
A Scientific hypothesis is a testable declaration that deals with the relationship between two or more variables or a proposed explanation for some observed phenomenon.
It is known that a scientific hypothesis is constructed prior to the investigation. This is because it assists you systematically in the overall experiment in order to derive the fact and understanding based on the evidence and inference.
Therefore, the correct option for this question is B.

Which is the best topic sentence for a paragraph comparing and contrasting moths and butterflies?
Although moths and butterflies look alike, there are important differences between them.
Most moths rest with their wings out flat, but butterflies rest holding their wings together.
So the next time you think you see a butterfly, look twice, because it might be a moth.
Butterflies are usually more brightly colored than moths and are active during the day.

1 How was the Flowing Water Model similar to
flowing water on Earth?
2. How was the Flowing Water Model different than
flowing water on Earth?
3. How I would change the Flowing Water Model to make it more like the actual geologic process on Earth?
Answer:
Flowing water model is a computer program not the real earth ecosystem.
Explanation:
The flowing water model is a simulated computer program that integrates the land, aster, and groundwater-surface systems and can calculate the demand for each land-use type. Such as agriculture, urban, native, and natural vegetation. It's similar to that of earth's flowing water as it based on the simar feature of the water system as of earth. Due to its just a simulation or model its cannot predict the varieties of the monsoon and ned's a single one-dimensional flow through a network that is set to incorporate time. But the earth is an unpredictable and dynamic system.1. The Flowing Water Model was similar to flowing water on Earth in that it involved the movement of water and sediment, simulating erosion and deposition processes.
It aimed to show how flowing water shapes landforms, like river valleys, canyons, and deltas, similar to natural water systems on Earth.
2. The Flowing Water Model was different from flowing water on Earth because it lacked the complexity and scale of real-world geologic processes.
It likely used simplified materials and conditions, unable to replicate the intricate interactions between water, sediments, and geological structures found in natural environments.
3. To make the Flowing Water Model more like the actual geologic process on Earth, it could be enhanced by incorporating more realistic materials, gradients, and variable flow rates.
Additionally, introducing obstacles and geological formations would mimic the natural complexity of river systems, allowing for a more accurate representation of the Earth's dynamic geological processes.

Summarize, using water potential, why water leaves the slugs tissues and moves into the surround environment.
Answer:
The salt pulls water out of the slug in light of the fact that the NaCl breaks separated into two particles (negative and positive charge) and this declines the water potential on the outside of the slug.
Explanation:
The proportion of the overall propensity of water to move starting with one zone then onto the next, and is regularly spoken to by the Greek letter Ψ (Psi). The salt pulls water out of the slug in light of the fact that the NaCl breaks separated into two particles (negative and positive charge) and this declines the water potential on the outside of the slug.

What is an organism? Include examples for both plants and animals.
Answer:
Explanation:
En biología, se llama organismo o ser vivo a un individuo singular y diferenciado, compuesto por un conjunto de materia orgánica jerarquizada y especializada. Lo constituyen sistemas de transmisión y comunicación bioquímica, que le permiten conservar su equilibrio interno a la vez que intercambiar materia y energía con el entorno que lo rodea. Dicho en otras palabras, un organismo es una entidad viviente, dotada de la capacidad de nutrirse, crecer, reproducirse y morir.
Todos los organismos conocidos, con excepción de los virus, están formados por células, y poseen un metabolismo que les permite garantizar su existencia y dar pie a sus procesos biológicos a cambio de intercambiar energía con el medio ambiente. El fin último de todo organismo parece ser la reproducción, esto es, la perpetuación de su especie y la transmisión de su material genético (herencia).
Químicamente hablando, los seres vivos se distinguen de la naturaleza que los rodea en su composición casi exclusiva a base de carbono, hidrógeno, oxígeno y nitrógeno, es decir, a base de moléculas orgánicas, estructuradas de manera muy diferente a las moléculas inorgánicas de la materia inerte.
