Flatworms (Platyhelminthes) are phylum of unsegmented, soft, flat invertebrates.
Flatworms have no body cavity which is why they are flat. The advantage of a flat body is facilitated respiration and circulation. Flatworms do not have respiration and circulation system. But, oxygen diffuses across the skin and reach all parts of the body thanks to a flattened shape. Also, it is easy to hide from predators because they can get almost everywhere thanks to the body shape.
The economic effects: The genetically engineered products have impacted on the availability of the food by providing the seeds for increasing the yield of the crop, these are resistant to disease, animals are also resistant to disease, they are tolerant to the adverse climatic conditions.May 8, 2019
Answer:
*furiously writes F until there was a true statement*
8. F (isotonic is where water diffuses in and out of the cell in equal rates to which it could move back and forth)
D.F (hypertonic solution is where the water will diffuse out from the cell as hypertonic solution's concentration is higher than the concentration of solute within the cell)
c.F (" but the water should be diffuse into the cell)
d.F (osmosis only related to water)
e.T (carrier proteins has the ability—it changes its shape to allow the molecules to pass through to the other side of the plasma membrane)
f. F (cuz facilitated diffusion issa passive transport and a passive transport must be going down the gradient aka from high to lower concentration)
