What else can I help you with?
Diatoms which are common members of phylum chrysophyta are mainly distinguished by their what?
They are distinguished by their characteristic cell wall which is composed of hydrated silica.
How much moisture can silica gel absorb?
Silica gel will adsorb up to 40% of its own weight in moisture.
What is one way people use silica?
a mineral used to make Glass, rocket proppellants idk what you need that for but thats what you can make it out of, you can also make batteries, and medicine Hope this helps! :)
How are silica and water related to volcanos explosiveness?
because
What is finely ground silica?
Silica mining and manufacturing companies grind the mined ore down to an average particle size ranging from 15 to 3 microns. All of the raw ore is naturally occurring silica that is typically surface mined. The finished product is much finer than industrial sand (e.g., playground sand, golf sand, filtration sand, etc.). The overall particle size distribution typically falls below a 200 mesh screen or 74 microns. The particle size distribution range is typically between 74 microns down to 5 microns. The finished material is fine in particle size similar to baking flour.Quartz is the most common silica crystal and the second most common mineral on the earth's surface. It is found in almost every type of rock; igneous, metamorphic and sedimentary. While quartz deposits are abundant, and quartz is present in some form in nearly all mining operations, high purity and commercially viable deposits occur less frequently. Silica sand deposits are most commonly surface-mined in open pit operations, but dredging and underground mining are also employed. Extracted ore undergoes considerable processing to increase the silica content by reducing impurities. It is then dried and sized to produce the optimum particle size distribution for the intended application. {sourcehttp://www.ima-na.org/industrial-sand}
Photosynthetic protists with boxlike double shells are?
Diatoms are photosynthetic protists with boxlike double shells known as frustules. These frustules are made of silica and provide diatoms with protection and structural support. Diatoms are an important component of aquatic ecosystems and play a significant role in the global carbon cycle.
Which group of protists possess calcium carbonate shells?
Foraminiferans (or forams) are single-celled protists with a calcium carbonate (CaCO3) shell around their plasma membrane. ***Straight out of my biology text book
Do shells have a high silica content?
Yes, shells such as those of mollusks, crustaceans, and other marine organisms typically have a high silica content. Silica is a key component of their shells and helps provide strength and structure.
What are radiolarian shells amde of?
Radiolarian shells are made of silica, which is a type of mineral that is common in the ocean. These shells are intricately formed by single-celled organisms called radiolarians and play an important role in ocean ecosystems.
What is the main component of the tiny shells of the members of the phylum Actinopoda?
Silica is the main component of the tiny shells of members of the phylum Actinopoda. These microorganisms produce intricate and often symmetrical silica shells, known as tests, which serve to protect and support their delicate structures.
Do protists have a cell wall or cell membrane?
Protists can have either a cell wall, a cell membrane, or both. The presence of a cell wall in protists varies among different species and can be made of various materials such as cellulose, silica, or chitin. The cell membrane is common to all protists as it is essential for controlling the movement of molecules in and out of the cell.
What substance makes up the greatest percentage of the shells of diatoms?
Silica -IAmReallyRone
Is silica aspirin?
No. Silica and aspirin have virtually nothing in common.
What photosynthetic protists have glassy two part cell wall made of silica?
diatoms
Are onecelled organisms with shells made of silica?
Yes, diatoms are one-celled organisms with shells made of silica. These shells are called frustules and are made up of two overlapping parts that fit together like a petri dish. Diatoms are a type of algae found in marine and freshwater habitats.
What protista has Glass or silica in shells?
Diatoms are a type of protist that have glass or silica in their shells. These microscopic organisms are known for their intricate and beautiful glass-like structures, which provide protection and help with buoyancy in water.
How do diatoms get food?
as diatoms move through water they filter particles through their two silica shells
