There are three main types of RNA molecules that are synthesised inside the cell:
1. rRNA: rRNA is the ribosomal RNA. These RNA molecules make up the ribosome of the cell.
2. tRNA: tRNA also known as the transfer RNA (previously as sRNA for soluble RNA) is the adaptor RNA that helps in the synthesis of proteins in the ribosomal complex.
3. mRNA: mRNA is short for messenger RNA. The gene present on the DNA is transcribed to form an mRNA molecule. This mRNA molecule holds the code for the amino acids present in the protein.
Hence mRNA carries the protein coding information to the ribosome.

Why have biologists changed many of linnaeus's original classification of organisms?
Answer:
They were originally classified based on visual characteristics that could be seen on the outside of the organism, however with the advancement of technology and science scientists realized that other characteristics (molecular, structural, etc.) should be considered.
Explanation:
If today nature has an order in the eyes of man, this is due to the work of the Swedish naturalist Carl Lineu, who in the 18th century, when comparing reproductive organs and structures of animals and plants, formulated the system of binomial classification of species. That is, if we can now call ourselves homo sapiens, such nomenclature of genus and species, respectively, is the result of Lineu's work. His contributions did not stop there, since in addition to the species' names, the naturalist grouped them into a hierarchical classification system. Thus, Kingdoms, Philos, Classes, Orders and their subcategories were born.
However, Lineu's classification system was originally established based on visual characteristics that could be seen on the outside of the organism, however with the advance of technology and science scientists realized that other characteristics (molecular, structural, etc.) should be considered.

To safeguard against groundwater contamination, sanitary landfills are ________. to safeguard against groundwater contamination, sanitary landfills are ________. located on slopes so water runs downhill located on industrial sites where groundwater is not used for drinking or agriculture lined with cement lined with plastic and compacted clay located in unpopulated areas
Sanitary landfills are safeguarded against groundwater contamination by being lined with plastic and compacted clay and being located in areas where the groundwater isn't used for drinking or agriculture.
Explanation:To safeguard against groundwater contamination, sanitary landfills are constructed with specific features. They are lined with plastic and compacted clay to act as a barrier between the trash and the natural soil below. This liner prevents potential contaminants in the waste from seeping into the groundwater.
Moreover, landfills are typically built in places where the geography or land use won't interfere with the natural flow of water in the area. They may be located on industrial sites where groundwater is not tapped for drinking or agricultural purposes, reducing the risk of trash pollutants seeping into water sources used by humans. Therefore, the location and construction materials used for sanitary landfills are both essential to protect groundwater resources.

To which reptiles, living or extinct, are crocodiles and alligators most closely related?
Final answer:
Crocodiles and alligators, which are part of the Crocodilia order, are most closely related to birds. Both are the only known living descendants of dinosaurs, with birds being descendants of dinosaurs that developed wings. Crocodilia originated around 84 million years ago, and their terrestrial ancestors appeared at least 220 million years ago.
Explanation:
Crocodiles and alligators are part of an order of large reptiles known as Crocodilia, which also includes creatures like caimans and gharials. These reptiles are most closely related to birds, which may seem surprising, but both groups are the only known living descendants of the dinosaurs. The ancestors of birds were actually dinosaurs that evolved wings and took to the skies. Hence, crocodiles and alligators look like they might be small dinosaurs because they share a common ancestry with these ancient creatures.
The Crocodilia lineage arose about 84 million years ago during the late Cretaceous period. Crocodilians are found in a variety of habitats in the tropics, such as rivers, lakes, and sometimes saltwater environments. They show diverse behaviors, including providing parental care, which is depicted in one example as the Siamese crocodile (Figure 15.43a). These reptiles spend substantial time in the water but also have the capacity for semi-erect locomotion on land. Among modern reptile orders, turtles originated around 250 million years ago, while ancestral crocodilians evolved at least 220 million years ago.

When your body digests alcohol, your stomach digests_____% of it?
Answer: 20%
The alcohol that is swallowed by a person avoids the normal digestive process. It travels down the esophagus into the stomach and the small intestine and goes right into the bloodstream. About 20 percent of the alcohol consumed by the body is absorbed in the stomach, and about 80 percent is absorbed in the small intestine. The liver is the organ that is particularly affected by alcohol because it is the main organ that processes alcohol.
