Substance A and substance B are mixed together. To separate the mixture, water is added, and substance A is filtered out. Then, the remaining liquid is heated to remove the water, leaving a residue of substance B. Which statement about substance A and substance B could be correct?
Substance A is rice, and substance B is sugar.
Substance A is rice, and substance B is sugar.
Substance A is sugar, and substance B is instant coffee.
Substance A is sugar, and substance B is instant coffee.
Substance A is sand, and substance B is alcohol.
Substance A is sand, and substance B is alcohol.
Substance A is alcohol, and substance B is salt.
The correct answer would be that substance A is rice, and substance B is sugar.
For substance A to be filtered out, it means that A is a water-insoluble substance and for substance B to be recoverable by evaporating off the water, it means that B is water-soluble.
Thus, A can neither be sugar nor alcohol because neither can be recovered by filtration. Also, B can neither be coffee nor alcohol because they can not be recovered as residue through evaporation of water.
Therefore, the only correct answer is that substance A is rice, and substance B is sugar because rice can be filtered out from water while the water-soluble sugar can be recovered by evaporating the water.

How does the Coulomb force affect charge interactions?(1 point)

Like and opposite charges attract.
Like charges attract, and opposite charges repel.
Like charges attract, and opposite charges repel.
Like and opposite charges repel.
Answer:
Like charges repel each other; unlike charges attract.
Explanation:
Like charges repel, and opposite charges attract.
According to Coulomb's law, the force of attraction between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between the charges.
If the Coulomb's force between two charges is positive, then the force is a repulsive force. This happens between two like charges.
If the Coulomb's force between two charges is negative, then the force is an attractive force. This happens between unlike charges.

Forming a hypothesis is the first step of the scientific method.
Answer:
The first step in the Scientific Method is to make objective observations. These observations are based on specific events that have already happened and can be verified by others as true or false. Step 2. Form a hypothesis.
Explanation:
The hypothesis is an educated guess as to what will happen during your experiment. The hypothesis is often written using the words "IF" and "THEN." For example, "If I do not study, then I will fail the test." The "if' and "then" statements reflect your independent and dependent variables

Una especie de mariposa presenta rasgos fenotípicos diferentes entre los miembros de sus poblaciones. Estos rasgos van desde una coloración verdosa y antenas cortas (características recesivas). El fenotipo más común (características dominantes) de esta especie es de coloración amarilla y de antenas tan largas que se pueden doblar. Realice el cruce entre dos mariposas que presentan fenotipo más común, pero de genotipos heterocigotos y determine los posibles rasgos fenotípicos que se pueden presentar.

A boy picks up an earthworm and place it on a white tile. He observed that the earthworm has difficulty in moving forward.
Explain why.
Answer:
A number of tiny hair like bristlez are present on the lower surface pf an earthworm's body. These bristles help it to get a good grip on the surface of q ground.However these bristles donot provide good grip on plain glass tiles.
Earthworms have microscopic hairs or bristles all over their body which provide the necessary traction while movement. These bristles or setae are present on each segment of their body and it imparts the necessary grip or anchorage for forward and backward movement.
Tile is smooth in nature so earthworms cannot move as the setae will not get sufficient surface support to move the body.

A technique that can be used to separate proteins based primarily on the presence of non-polar residues on their surface is called A) ion-exchange chromatography. B) gel filtration chromatography. C) affinity chromatography. D) gel electrophoresis. E) hydrophobic interaction chromatography.
Answer:
E) hydrophobic interaction chromatography.
Explanation:
Hydrophobic interaction chromatography (HIC) is a methodology used to separate protein molecules depending on their hydrophobicity. HIC enables the separation and purification of proteins by using a reversible interaction between the target protein and the hydrophobic ligand of a HIC resin such as, for example, methacrylate-based beads. This interaction is influenced by the running buffer (high salt concentrations favor hydrophobic interactions). HIC enables the separation of proteins under low denaturation conditions, thereby preserving their biological functions.
How do organisms in the rainforest compete for biotic and abiotic factors? (Emergent layer, canopy layer, understory, forest floor?) In the ecosystem. Giving brainliest.
Organisms in the rainforest compete for biotic and abiotic factor by using resources that are available in the surrounding environment.
Competition occurs when the resources are available in scarce or limited amount. When there is an abundant amount of resources, there is no competition between organisms. The organism which is stronger than other organism can use more resources i.e. water, food and space etc and increase its population.
Those organisms which feed on similar food and other resources can compete with each other and the stronger organism will use the resources in large amount.
