Cilia are the structures on the ventral side of the planaria that propel it forward.
Planaria is a type of flatworm that belongs to the class Turbellaria. Some species of planaria are terrestrial, while some are aquatic. Planarians have a soft and ciliated body. Cilia are hair like organelles situated on the ventral dermis of the planarians. Cilia function for locomotion by propelling the planarians forward, and allowing them to move smoothly on a layer of mucus.
If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, the relative concentrations of solute and water are equal on both sides of the membrane. ... When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.
The correct answer is Protozoa, plant and fungi.
The kingdom Protista consits of several organism that includes Protozoa, plants and fungi. Protists are the first eukaryotes that came on earth, it includes multicellular organisms and unicellular organisms as well.
- It includes plant like protists called as autotrophs.
Example: Red, brown and green algae.
- It also includes fungi like protists called as decomposers.
example: slime molds and water molds.
- It also includes protozoans like Zooflagellates and cilliates.
Answer:
Individual adaptation means the adaptations acquired by individuals during their lifetime or behaviors sharpened by experience. Species adaptation means the adaptation of species as a whole to their environments by the process of natural selection.
Explanation:
Adaptation means any change in an organism that increases the efficiency of that organism and gives a better chance to survive and reproduce. The changes may be developmental, anatomical, behavioral or physiological.
Individual adaptation means the adaptations acquired by individual organisms during their lifetime (muscles strengthened by exercise) or behaviors sharpened by experience. It is a short-term change in response to conditions with a short-term benefit. For example, on a hot day, the production of sweat increases to cool our bodies. Adaptations achieved by individuals cannot be passed on to their offspring, except in the form of learned behavior.
Species adaptation means the adaptation of species as a whole to their environments, which occur as a result of natural selection (survival of the fittest). Highly adapted species are better suited to their particular environment than a less-adapted species but less likely to survive changes to that environment while less-adapted species are well-suited to survive changes in that environment. For example, a highly adapted flowering plant species depend on a specific insect that exists only in its present environment for pollination and if that specific insect species become extinct, the plants will also cease to exist.
They’re both cells but prokaryotic cells only have dna and no organelles. Eukaryotic cells have organelles and dna. They both have dna.
