The relationship of structure to function is one of the major themes in biology. For the following structure/function pairs, describe the structure and then explain how the function is related to the
structure.
Membrane protein structure/active transport or facilitated diffusion
Answer:
Membrane protein is made up of phospholipid bilayer.
Explanation:
Membrane proteins have one or more segments that are embedded in the phospholipid bilayer. This structure helps cells to maintain their shape, carry out changes triggered by chemical messengers, and transport material. Cell membrane have thousands of proteins that are embedded in the cell's lipid bilayer. The proteins present in the cell membrane is responsible for the active transport means use energy to transport molecules and ions across the cell membrane.

3. Synthesize in your own words, explain why scientists believe that threats to amphibians present a warning about a number of environmental threats to Earth's biodiversity Refer to the Case Study.
Explanation:
Scientists give three reasons. First, amphibians are sensitive biological indicators of changes in environmental conditions such as habitat loss, air and water pollution, ultraviolet (UV) radiation, and climate change.Amphibians are sensitive biological indicators of environmental circumstances such as habitat loss, pollution of the air and water, ultraviolet (UV) radiation, and temperature change.
What is biodiversity?The variety and variability of life on Earth is referred to as biodiversity or biological diversity. A measure of variation at the genetic, species, and ecosystem levels is called biodiversity.
Biodiversity refers to the variety of all the diverse species of organisms that dwell on our planet, including the plants, animals, insects, and microorganisms.
Each of these things exists in a delicate balance and coexists with the others in ecosystems that nourish and sustain life on earth.
Amphibians are sensitive biological markers of changes in environmental conditions like temperature, UV radiation, habitat loss, and air and water pollution.
Thus, scientists believe that threats to amphibians present a warning about a number of environmental threats to Earth's biodiversity.

Why don't negative mutations usually increase in frequency in populations?
Answer:
Within a population, each individual mutation is extremely rare when it first occurs; often there is just one copy of it in the gene pool of an entire species. But huge numbers of mutations may occur every generation in the species as a whole.

When the concentration of a solution is higher inside a cell than it is outside of the cell, is the solution inside hypertonic,isotonic, or hypotonic?
Answer:
Hypertonic solution
Explanation:
Hypertonic solution refer to the solution of a cell if the solute concentration is higher inside than outside and it cannot cross the membrane. In Hypertonic solution, Water crosses the cell membrane in both directions which result in more b water leaving the cell than entering it. Therefore, a cell place in this solution will shrink due to exosmosis.

What is the main relationship among archosauria, diapsida, and reptilia clases?
Answer:
Archosauria (the "ruling reptiles") is a major group of diapsids, differentiated from the other diapsids by the presence of single openings in each side of the skull, in front of the eyes (antorbital fenestrae), among other characteristics. This continues the tetrapod trend of the reduction of skull bones by the fusion of multiple bones and the opening of fenestrae in the skull. This helps to lighten the skull, provides more room for muscles and other tissues, and allows more skull flexibility (kinesis) when eating. Other typical archosaurian characteristics include another opening in the lower jaw (the mandibular fenestra), a high narrow skull with a pointed snout, teeth set in sockets (called thecodont tooth implantation), and a modified ankle joint.
Diapsids ("two arches") are a group of amniote tetrapods that developed two holes (temporal fenestra) in each side of their skulls about 300 million years ago during the late Carboniferous period.[1] The diapsids are extremely diverse, and include all crocodilians, lizards, snakes, tuatara, turtles, and birds.[2] Although some diapsids have lost either one hole (lizards), or both holes (snakes and turtles), or have a heavily restructured skull (modern birds), they are still classified as diapsids based on their ancestry. At least 7,925 species of diapsid reptiles[3] exist in environments around the world today (nearly 18,000 when birds are included).
Reptilia, presented as a Class in our classification, includes turtles (Testudines), snakes and lizards (Lepidosauria), crocodiles and their relatives (Crocodilia), and birds (Aves), as well as a number of extinct groups.
