definition of hypotonic solution isotonic solution and hypertonic solution
Answers
Answer: hypotonic solution- a lower concentration of solutes than another solution
isotonic solution- a solution that contain equal concentrations of impermeable solutes on either side of the membrane and so the cell neither swells nor shrinks.
hypertonic solution- A solution that contains more dissolved particles (such as salt and other electrolytes) than is found in normal cells and blood.
Explanation: searched it up for you
Answer:
Hypotonic solution: lower concentration of solutes compared to a medium or reference solution.
Isotonic solution: same concentration of solutes compared to another solution.
Hypertonic solution: higher concentration of solutes compared to another one.
Explanation:
A solution is a mixture where a solute is diluted in a solvent that is usually homogeneous, and the solute and solvent do not interact through chemical reactions.
In biology, we speak of hypertonic, isotonic and hypotonic solutions when comparing intracellular and extracellular media at a given time. Taking as reference the cellular cytoplasm:
Hypotonic: lower concentration of solutes in the extracellular space Isotonic: the same concentration of solutes, with respect to the cytoplasm Hypertonic: higher concentration of solute in the extracellular space.The difference in concentrations given by the hypotonic and hypertonic solutions define the dynamics of the movement of solutes or water through the cell membrane, forming gradients, where a solute passes from the place of highest concentration to the place of lowest concentration, or the water passes from the medium with the lowest concentration of solutes to the one with the highest concentration.

The San Marcos salamander, Eurycea nana, is a light reddish-brown
translucent salamander about 2-5 cm in length. E. nana is found only in
Spring Lake and a portion of the San Marcos River.
Which human activity would most likely decrease the ability of the
salamanders to survive?
The addition of a new food source into the river that limits competition for
resources
Tourism that helps fund the educational programs related to river ecosystem
conservation
Public transportation that reduces the number of automobiles that contribute to
pollution runoff into the river
Increasing water consumption that decreases the flow of clean water from the
springs that feed the river
Answers
Answer: Increasing water consumption that decreases the flow of clean water from the
springs that feed the river
Explanation: Because the salamanders have less clean water, pollution becomes more of a problem, also all of the other options would help the salamanders.
The human activity that would most likely decrease the ability of the salamanders to survive is increasing water consumption, which decreases the flow of clean water from the springs that feed the river, which is the last option.
What are the human activities that lead to habitat loss?The salamander is only found in a limited area of the San Marcos River, which relies on clean water from the springs, so decreasing the flow of clean water would negatively impact the salamander's survival, as it depends on specific water conditions for survival. As water is withdrawn from the springs to meet human needs, such as agriculture, industry, or household use, less water is available, which can have a detrimental effect on the habitat that the salamander requires because of human needs.
Hence, increasing water consumption decreases the flow of clean water from the springs that feed the river, so the last option is the correct option.

To keep it simple the answer is Mitosis.
The process of mitosis generates new cells that are genetically identical to each other. Mitosis helps organisms grow in size and repair damaged tissue. The process is Mitosis.
What is Mitosis?A cell prepares for cell division by replicating its chromosomes, segregating them, and creating two identical nuclei during the mitotic phase. The cell's contents are often evenly divided into two daughter cells with identical genomes after mitosis.
Mitosis can be compared to copying an instruction manual. Give two copies of each page, one to each of the two recipients.
A cell copies each chromosome during mitosis and distributes one copy to each of its two daughter cells.
Therefore, The process of mitosis generates new cells that are genetically identical to each other. Mitosis helps organisms grow in size and repair damaged tissue. The process is Mitosis.

Franklin was performing an experiment by combining hydrochloric acid and sodium hydroxide. He measured the mass of his reactant materials to be 35g. The reaction resulted in the production of salt and water. He reported that his products weighed 32g. Which best describes the results of Franklin’s experiment? No error occurred, some of the products are always lost as heat. An error occurred, the mass of the reactants should equal the mass of the products. An error occurred, the products should weigh more than the reactants. No error occurred, water is not weighed when determining the weight of the products.
Answers
Answer:
B) an error occurred, the mass of the reactants should equal the mass of the products.
Explanation:
The answer choices are:
A) no error occurred, some of the products are always lost as heat.
B) an error occurred, the mass of the reactants should equal the mass of the products.
C) an error occurred, the products should weigh more than the reactants.
D) no error occurred, water is not weighed when determining the weight of the products.
Solution
The basis to answer this question is the law of conservation of mass.
Any chemical reaction satisfies the law of conservation of mass: mass cannot be either created nor destroyed, so, always, the mass of the reactants equal the mass of the products.
Thus, since he measured the mass of his reactant materials to be 35g and he reported that his products weighed 32g, his data are in clear contradiction of the law of conservation of mass. So, there is an error in his results: the mass of the reactants should equal the mass of the products.

Chemical symbol and chemical formula
Atomicity and valency
Answers
Answer:
Atoms are the basic units comprising matter, and interact in a variety of ways.
Explanation
The most fundamental unit of matter that makes up elements is called atoms. Atoms comprise nucleus-orbiting electrons- while protons and nuetrons make up a stable nuclues. Here, the neutrons are uncharged, while the negatively charged electrons are attracted to the positively charged protons at the atom's center
The number of protons the atom determines its atomic number, and the sum of protons and neutrons determine the atomic mass.
Elements in the periodic table, are typically represented by chemical symbols- abbreviations of their atomic name. They are arranged in order of valency- atoms in the same group typically have the same number f electrons on their valence shells, and thus their physical properties behave similarly (conductivity, melting points, boiling points).
Valence electrons, on outer valence shells, also influence bonding. The atoms donate, accept or share valence electrons in order to achieve more stable atoms. Bonding between elements form molecules, that may interact with molecules to form compounds.

What has the most control over water being a gas, liquid or solid ice? A. The amount of water B. It’s temperature C. If its being used D. It’s age
Answers
Answer:
B. Its temperature
Explanation:
The different states of matter are largely influenced by both temperature and pressure. The temperature has most control over water being a gas, liquid or solid ice. If the temperature is very high, the molecules in the water increases their kinetic energy. This movement causes the compound ([tex]H_{2} O[/tex]) to break its bond. Thus, it turns into a gas. On the contrary, if the temperature is very low, the molecules of the water moves closer to each other. This causes them to solidify and turn into ice.
