Rna polymerases differ from dna polymerases in that

pentagon [3]

Answer: RNA polymerases synthesize RNA from a DNA template while DNA polymerases synthesize DNA from a DNA template.

Explanation: RNA polymerase is an enzyme that catalyzes the synthesis of an RNA strand from a DNA template. The process of copying the genetic message in the DNA template into an RNA strand is called transcription. DNA polymerase is the enzyme that catalyzes the synthesis of two new strands of DNA using DNA templates. The process of synthesizing two identical copies of DNA from a double stranded DNA is called replication. RNA polymerase catalyzes transcription while DNA polymerase catalyzes replication.

Lipid polymers are often created by numerous non-polar fatty acid chains with a polar head lined up. Which is the best explanati

fomenos

Polymers are macromolecules composed of similar monomers joint through chemical bonds. Lipids are not composed of similar basic units, so they are not considered to be polymers. There is no formation of a polymer lipid.

------------------------------------------------

Together with proteins, carbohydrates, and nucleic acids, lipids are essential components of biological structures and are part of the biomolecules group.

When talking about polymers, we are referring to molecules composed of multiple similar units, the monomers. When many monomers join through chemical bonds, through the polymerization process, they form a polymer. These units do not need to be identical.

According to the polymer definition, polysaccharides, proteins, and nucleic acids are polymers. Lipids are not polymers because they are not composed of a repeated sequence of basic units.

Lipids are individual medium-sized molecules. There are different types of lipids: triacylglycerols, wax esters, phosphoglycerides, sphingolipids, and sterols.

According to their structure:

Simple lipids ⇒ Composed of an alcohol molecule and fatty acids.
Complex lipids ⇒ They are composed of alcohol, fatty acids, and different non-lipidic components, such as phosphates, amino acids, glucyds, amines, etcetera. These are the amphipathic molecules.

Membrane lipids are amphipathic molecules with hydrophilic heads -negatively charged phosphate group- and hydrophobic tails. In membranes, they are arranged with their hydrophilic polar heads facing the exterior and the interior of the cells, while their hydrophobic tails are against each other, constituting the internal part of the membrane.

A marine algae called Emiliana huxleyi can overgrow, creating an algal bloom covering thousands of square kilometers of ocean. A

malfutka [58]

Answer:

Carbon

Explanation:

Emiliana huxleyi is a coccolithophore, a eukaryotic unicellular alga that grows in the oceans of the world, from the tropic to the subarctic areas. It has an external calcite skeleton, which is equivalent to aproximately one thirth of the CaCO₃ marine production. Under favorable conditions, this species can overgrow producing blooms, which are giant aggregations that can cover several square kilometers. These blooms can seriously affect the aquatic ocean life on a global level by running out nutrients and forbidding sunlight to reach certain depth levels.

When these blooms are infected with a specific virus called EhV, their calcic carbonate exoskeletons explode dispersing particles in water and releasing carbon and minerals back to the oceans. EhV viruses act as a biological control for these blooms.

Why are phytoplankton essential to aquatic life zones? filter pollution from water provide basis of food chains moderate water t

lesantik [10]

The answer is provide basis of food chains.

Plankton includes a diverse group of organisms that live in the water, but are not capable of active swimming against the current. They are usually present in the upper part of the ocean, where is enough sunlight.
They are the basis of food chains in water ecosystems. They provide food for different animals, such as jellyfish, shrimps, whales, etc.
