Answer:
-Because membranes are fluid, membrane proteins and phospholipids can drift about in the membrane.
-The diverse proteins found in and attached to membranes perform many important functions.
-The framework of a membrane is a bilayer of phospholipids with their hydrophilic heads facing the aqueous environment inside and outside of the cell and their hydrophobic tails clustered in the center.
Answer:
A. Salamanders
Explanation:
Specialists species are species that can thrive in a unique and limited range of resources. They require a specific environmental condition to reproduce and survive in environment and also have limited or few diets they need for nutrition. These limiting characteristics put them at a disadvantage of being endangered and threatened.
Salamanders are endangered species that are fast going into extinction. They require wetland (freshwater pools) for reproduction to be possible, and feed mainly on insects. This makes them specialist species.
Ospreys, snapping turtles, and beavers are all generalist species. They can all thrive in a wide range of environmental conditions, and also have varieties of diets they can get nutrition from to survive.
<h2>Material Do Alice and Julio Likely Work - Option B</h2>
Alice and Julio’s company makes protective coverings for off-roading vehicles. Alice’s job involves harvesting a natural polymer from trees. Julio’s job is to take that material and change it chemically to create a synthetic polymer.
Alice and Julio most likely work with natural rubber and vulcanized rubber. Alice works with natural rubber, and Julio works with vulcanized rubber.
The best thing to do is this:
the subjects in the experimental group should be given large, daily dose of vitamin C while the control group subjects should be given a daily dose of sugar pills that are disguised as vitamin C.
The research can then observe the differences between the two groups.
There are many examples you can choose from, but one great example, a venus fly trap, and a lotus, for example. The two examples given differ because they:
*provide themselves with different types of foods
*have a different system of reproducing, as well as growing
*and live in two different types of environments.
Also, remember, the fly trap is a carnivorous plant, while the lotus is not
