definition of hypotonic solution isotonic solution and hypertonic solution
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.
What happens to a population in response to a density-independent limiting factor?
Answer: Hope this helps!
Explanation:
Density-dependent limiting factors cause a population's per capita growth rate to change—typically, to drop—with increasing population density. ... Density-independent factors affect per capita growth rate independent of population density. Examples include natural disasters like forest fires.
Explain the process of radioactive decay. What happens during radioactive decay, and what is the result at the end of radioactive decay?
Answer:
this is the answer straight off the site DO NOT COPY AND PASTE but along these lines is what its looking for
Explanation:
Radioactive decay is the process in which the nucleus of an unstable isotope spontaneously changes, releasing particles and energy. An unstable isotope will continue to decay until it reaches the stable form of either a different isotope of the same element that is stable or a different element that is stable.

Answer:
No, the amoeba does not die, it simply transforms into the daughter cells.
Explanation:
The parent cell copies its genetic material and divides. This process is not going to kill the amoeba who went through it.

Answer:
Gamete cell
Explanation:
Because I just got the question wrong and it showed me the right answer.
A gene alteration that takes place in a parent's reproductive cells (egg or sperm) and has an impact on the child's genetic makeup is known as a “germ line mutation.”
What is mutation?A more or less permanent change to the genetic code (the genome) of a cell in a living thing or of a virus that can be passed on to the offspring of the original cell or virus. Unlike viral genomes, which can be either DNA or RNA, all creature genomes are made of DNA.
Somatic mutation: A variation in a gene that takes place in the developing embryo that may evolve into a child after conception. All cells in the developing organism have these, except for the sperm and egg.
Therefore, a “germ line mutation” is a gene change that occurs in a parent's reproductive cells (egg or sperm) and affects the child's genetic composition.

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
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.

Where does warm water accumulate in the Pacific Ocean during El Niño?
Answer:
Explanation:
During El Niño, when the trade winds are weak or even occasionally reverse themselves, the amount of cold water that comes to the surface is reduced. Warm waters in the west Pacific Ocean slosh to the east. Now there is a large area along the equator, where ocean temperatures are above normal.

The transport of ions across a membrane is powered by the tomat ATP ADP
During cellular respiration, the electron transport chain is coupled to the generation of an electrochemical gradient across the mitochondrial inner membrane.
The statement 'the movement of motor proteins is powered by the formation of ADP and inorganic phosphate from ATP' describes an energy-releasing process that is coupled to the energy-requiring process in the cell.In cellular respiration, an electrochemical gradient is created by pumping ions (e.g. H+) against a concentration gradient from the mitochondrial matrix into the intermembrane space.Subsequently, this gradient is used by a protein complex known as ATP synthase to generate ATP (the energy coin of the cell) from ADP and monophosphate.In conclusion, the statement 'the movement of motor proteins is powered by the formation of ADP and inorganic phosphate from ATP' describes an energy-releasing process that is coupled to the energy-requiring process in the cell.

How might an individual lose their sight or their hearing but not have direct damage to their eyes or ears
An individual can lose their sight and hearing ability without any direct damage to their eyes or ears due to the condition known as Usher syndrome, which is a genetic disease.
• Usher syndrome is the most common syndrome that influences both vision and hearing.
• The prime signs of the syndrome are hearing loss or deafness and an eye disease called RP or retinitis pigmentosa.
• In Usher syndrome, hearing loss can take place due to the unusual growth of hair cells within the inner ear.
• The RP at the beginning results in night blindness and a loss of side vision due to the progressive degeneration of retina cells.
• With the advancement in RP, the field of vision becomes more narrow till the central vision remains, the condition is termed tunnel vision.
Thus, it is the Usher syndrome, which can lead to loss of sight or hearing, however, does not cause direct damage to the ears and eyes.

The process of mitosis generates new cells that are genetically identical to each other. Mitosis helps organisms grow in size and repair damaged tissue.
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.

what are some outcomes of nuclear fusion?
A.produce larger materials from the collision of smaller materials
B.Release energy
C.produce smaller materials from the collision of larger materials
Answer:
A. produce larger materials from the collision of smaller materials
Explanation:
The outcome of nuclear fusion reaction is that it produces larger materials from the collision of smaller materials.
Nuclear fusion is the combination of small atomic nuclei into larger ones with the release of a large amount of energy. The energy released provides the needed temperature for another set of atoms to fuse. This process in turn yields a bulkier material accompanied with the release of a lot of energy.Which of the following factors have an affect on biodiversity?
