The most appropriate lighting for a reptile enclosure which ensure ultraviolet -B exposure. Reptiles depend upon skin manufactured vitamin D3 and has no capability to use the vitamin D3 which is available in the food they eat.For these reason reptile must bask in the sun or the UVB emitting bulb which help to maintain vitamin D3.
Answer:
Organelles are also called vesicles within a cell. And they really have a function that's important, because we need to compartmentalise all the functions within the cell. So there needs to be a membrane around the mechanisms for making a different product within a cell. So really, organelles are all membrane-bound.

Answer:
allopatric speciation by dispersal
Explanation:
Allopatric speciation is a form of speciation (creation of new species) that occurs as a result of geographic isolation. This means that a part of population becomes physically separated from the initial main population. There is no gene flow between these two populations and as a result the two populations reach a high level of genetic divergence. They can no longer interbreed which means they become two different species (speciation).
One of the factors that contribute to the allopatric speciation is dispersal.
New populations evolve as result of mutation, genetic drift and natural selection.
Generalized anxiety tends to initially arise during the mid-teens through the mid-20s.
<span>Anxiety disorders are the most common mental illness in the U.S., affecting 40 million adults in the United States age 18 and older. </span>Generalized anxiety disorder tends to occur with other anxiety disorders and with depression. Because the comorbidity is so high, researchers believe that many of the factors involved in predicting anxiety disorders, in general, are particularly important for understanding Generalized anxiety disorder.
