Meanwhile, the scientists have found their work convoluted and disrupted by the accelerating rate of extinction – the disappearance of both known and unknown species – which is a direct result of humankind’s relentless destruction of habitat. In our Southwestern deserts, for instance, the scientis...
As for reptiles and amphibians, more than 150 species “occur in the Southwest; this is partly due to the region's diverse habitats,” says the USGS inScience for a Changing World. “Compared with the moister habitats of eastern North America, the southwestern amphibian fauna is relatively po...
There areover 800,000 named speciesin the Phylum Arthropoda, named from the Greek arthros (= jointed) and poda (= foot), including the familiar arachnids, crustaceans, and insects, together with a host of less familiar critters, like centipedes, millipedes and sea spiders. All arthropods have...
1. True or false: The largest big cat species to ever live is believed to be the saber-toothed tiger. True. According to estimates the saber-toothed tiger could have weighed up to 880 pounds (400 kilograms) and measured more than 7.2 feet (2.2 meters) in length, making it the largest...
Classify plants. After you have placed the organism into the plant kingdom, the next step is to determine if the plant is a seed plant, which includes trees and flowers, or a nonseed plant, which includes algae, mosses and ferns. Seed-bearing plants can then be further classified into Gy...
While scientists may debate the methods used to calculate this probability of extinction, therefore, the set number of years would need to be defined, conservationists could identify at-risk species using this standard of measurement. (1803NA) ...
And that is exactly what the SARS-CoV-2 does, and what distinguish it from the previous corona species. Resuming some of the until now identified main features of the new SARS-CoV-2 and of its corresponding disease coined as COVID 19: The latter reflects the height of the power of the...
What is the importance of taxonomy? How do species extinction affect classification? How does particle size affect how sediment gets sorted in water? How has satellite technology helped the study of oceanography? How are crystals of minerals classified?
An axenic organism, as here defined, is a species free from any life apart from that produced by its own protoplasm” [4] (p. 116). According to Brand et al. (2013), an axenic culture is defined as a culture containing no other living organism except the strain of interest [1]. A...
responsible for making the shell. Shells continue to grow as mollusks grow, so the length of time it takes to produce a shell can vary from species to species. Many mollusks go through a larval stage in their development, so the actual start of shell production can differ among species as...
