What are the groups of gymnosperms? Of the three broad groups of protists, which are heterotrophs and which are autotrophs? What are the two common characteristics of the clade Lophotrochozoa? Were members of the clade Testudines alive around the time of the dinosaurs?
ProtistProtists are eukaryotic organisms that are primarily unicellular and microscopic. They are mostly aquatic, and examples of protists include amoeba, diatoms, dinoflagellates, plasmodium and many more.Answer and Explanation: Three examples of protist symbiosis: Symbiosis with corals: In this ...
there are some multicellular protists. They can live on their own; however, most thrive in colonies, depending on one another for survival. They are asexual and reproduce quickly through fragmentation or mitosis. Protists can be broken down into three groups: fungal-like protists that take in ...
Earth (or, "the earth") is the only planet presently known to support life, and its natural features are the subject of many fields of scientific research. Within the solar system, it is third nearest to the sun; it is the largest terrestrial planet and the fifth largest overall. Its mo...
What Are Biofilms? Biofilms are a collective of one or more types of microorganisms that can grow on many different surfaces. Microorganisms that form biofilms includebacteria,fungiandprotists. One common example of a biofilmdental plaque, a slimy buildup of bacteria that forms on the surfaces ...
These arguments are familiar, in part, because they are made by two quite different groups of critics. First, there are researchers who are interested in describing evolution, but not very interested in adaptive function. To these researchers, a lot of valid research in evolutionary biology can ...
As recently as the 1990s, the living world was divided into five kingdoms, the animals, plants, fungi, protists, and bacteria (Whittaker1969). Comparison of rRNA sequences (which presumably are resistant to evolutionary drift) has revised this classification scheme into three domains, phylogenetical...
Paleontological reconstructions of plankton community structure during warm periods of the Cenozoic (last 66 million years) reveal that deep-dwelling ‘twilight zone’ (200–1000 m) plankton were less abundant and diverse, and lived much closer to the
a five-carbon sugar called ribose and one to three phosphate groups. The bases in nucleotides can be either adenine (A), cytosine (C), guanine (G), thymine (T) or uracil (U). Nucleotides are the building blocks of the nucleic acids DNA and RNA; A, C and G are found in both nucl...
Algae are a diverse group of aquatic organisms that have the ability to conduct photosynthesis. There exists a vast and varied world of algae that are not only helpful to us, but are critical to our existence.
