I think the answer to this question is hypertonic to hypotonic as diffusion is the movement of water from a high to low concentration and hypertonic contains a high concentration of solutes and hypotonic contains a low concentration of solutes (the are opposites). Hope this makes sense
Answer: Commensalism
Explanation: Well you can already eliminate parasitism because that is when an organism leeches off another. Mutualism is when one organism needs to depend on another compared to A where both are benefited. Then you can eliminate d because competition is when two organism compete with each other for survival not benefiting them both.
Answer:Phaeophyta--Described as "hairy" in appearance produce alginic acid, which can be used as a thickening agent.
Rhodophyta ;are utilized commercially to produce carrageenan and can photosynthesize at depths greater than 10 meters
Chlorophyta;Considered the progenitor of land plants, have 18S rRNA sequences comparable to plants
Chrysophyta;The is a diverse group that includes the diatoms, a major component of phytoplankton
Explanation:algae are a diverse group of organisms with majority of them living in water and a few on land. They are green and contains chlorophyll.they also contains phycobillins pigments.
Chlorophyta are green algae that exist in water habitat an example is Chlamydomanas reinhardi.they have similar structures with higher plants such as chlorophyll, cellulose cell wall and stores food as starch.
The chrysophyta includes diatoms.diatoms have a cell wall composed of pectin and deposits of silica. They may occur in large deposit as diatomaceous earth.
Phaeophyta--are brown algae. An example is sea weed they are found in deeper ocean waters. Sea weed has a thallus which branches into a basal holdfast that aids attachment to rocks.their blade allows the plant to float
Rhodophyta are algae which are sometimes Unicellular in form they have a characteristic red color due to the presence of phycoerythrin along with phycocyanin, chlorophyll.they are used as source of algar for microorganism culture.
