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.

Which statement best describes the human respiratory system?
The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs, and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide.
Answer: It is composed of a network of moist passageways that permit air to flow from the external environment to the lungs.

How can humans influence traits in dogs or other organisms?
Answer:
In artificial selection, humans have the capacity to influence certain characteristics of organisms by selective breeding. One can choose desired parental traits determined by genes, which are then passed on to offspring.
Dog breeding is another prime example of artificial selection. Although all dogs are descendants of the wolf, the use of artificial selection has allowed humans to drastically alter the appearance of dogs.
Explanation:
Humans can influence traits in dogs or other organisms by the process of artificial selection through which desired characters can be added to the offspring.
How can humans influence traits in other organisms?Humans can influence the process of natural selection by the process of artificial selection, or selective breeding. In artificial selection, humans can select a specific set of desirable traits in the agricultural plants or animals, and thus produce desirable offspring (products) for benefit.

A city experiences a heavy rainfall. Days later, when no rainwater is present, rock, debris, and soil fall down a steep hill. Which type of mass movement does this describe? creep landslide mudflow slump
Answer:
I think the answer is landslide
Landslide is the massive movement of material from high altitude to low altitude, producing slope breaks. The correct option is B. The type of mass movement described in the example is landslide.
What is a landslide?A landslide can be defined as a massive movement of materials that include rocks, soil, plants, debris, and other elements composing the ground.
Mass of material moves from high altitude to low altitude due to the action of gravity and the influence of other factors as humidity excess.
These movements occur because the material is exposed to external forces (gravity) that supersede the strength of these materials producing slope breaks.
Other factors such as rains, increase in water level, snowmelt, erosion, earthquakes, human activities, and others influence the landslide occurrence.
The correct option is B. The type of mass movement described in the example is landslide.

A scientist at the polar ice cap was studying an ice sample from hundred of meters below the surface. While examining the ice, the scientist found some cells from many years ago. Using an electron microscope, the scientist identified these cell structures: a cytoskeleton, mitochondrion, nucleus, cell wall, and ribosomes. What kind of organism did the scientist find? (LS1.2)a. plantc. virusb. bacteriad. animal
Answer:
the organism is a plant.
Explanation:
As the scientist, a cytoskeleton, mitochondrion, nucleus, cell wall, and ribosomes, we can say that it is a eukaryotic cell since it has a differentiated nucleus. Also within eukaryotic cells, plant cells are those that have cell walls.
All structures are typically found in a plant cell.

The function of the cork cambium is to produce
Answer:
The cork cambium produces cork and phelloderm.
Explanation:
Cells' structural components decide their function. Cells arrange themselves into tissues, where specialized cell types carry out their functions in tandem. As cells mature, their function may even change over time, as they undergo certain subcellular changes in protein expression and signaling.
In larger plants, rigid tissues are needed to help support their modified stems, and transport water, minerals, other nutrients and food to different regions. Cork cambium is an unspecialized tissue found in the outermost plant layers. These act as meristematic regions; here, new tissues arise, growing outwards- these include:
phelloderm- they mature into inner secondary cortex cork- dead air-filled cells called cork that form a strong protective layer on the stems of woody vascular plants.Please help me! It’s suppppppper importanf

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 crossing of a hybrid and a dominant purebred will always result in offspring which are what?
Answer:
Dominant
Explanation:
A hybrid trait is also known as heterozygous, which is the combination of the dominant and recessive alleles of a gene. On the other hand, a purebred is combination of the same two dominant alleles or the same two recessive alleles. For example, in the gene coding for height, allele for tallness (T) is dominant over the allele for shortness (t).
A purebred for this trait will either be "TT" or "tt" while a heterozygous or hybrid will be Tt. Hence, according to this question, crossing of a hybrid (Tt) and a dominant purebred (TT) will always result in offspring which are DOMINANT (see attached image).
