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.

The phase in the life cycle of a plant that produces spores

DanielleElmas [232]

Answer:

Plants have two distinct stages in their lifecycle: the gametophyte stage and the sporophyte stage. After reaching maturity, the diploid sporophyte produces spores by meiosis, which in turn divide by mitosis to produce the haploid gametophyte. The new gametophyte produces gametes, and the cycle continues.

Higher viscosity of blood will increase the amount of stress placed on the heart while it is pumping. Viscosity of blood is high

Paul [167]

Answer:

C) hematocrit is highest

Explanation:

The viscosity is the property of the fluid substance related to the flow of the resistance. The flow of the resistance increases when the amount of content in the fluid increases.

The flowing blood contains the water and the other components like the cells and proteins therefore it also exhibit the viscosity. The viscosity in blood happens when the cells and molecules interact with each other therefore measure of these components indicated about the viscosity of the blood.

The hematocrit is the ratio of the proportion of the red blood cells present in the blood to the total volume of the blood. The viscosity of blood, therefore, increases when the hematocrit is high and decrease when the hematocrit component is low.

Thus, Option-C is the correct answer.
