Why are frogs absent on the galagos and other oceanic islands?

natita [175]

Frogs are absent on the Galapagos Island and other oceanic islands because there is many predators in there, such as sharks, who eat frog eggs they nest.

if the amount of paved land in the United States continues to increase, how might the biosphere be affected?

BabaBlast [244]

<span>Continuation of human development with paved land would fragment the biosphere even more. There would be small populations of animals in pockets within the paved land that might contribute to more diversification of species.</span>

Blue, brown, and green beetles from a forest migrated to a rocky mountain after a natural disaster. In the new environment, brow

Natasha2012 [34]

Answer: Most of the beetles will be brown because they have a higher likelihood of reaching reproductive age.

Natural selection is the process of selection by nature in which an individual organism exhibiting more favorable phenotypic characteristics has more chances of survival and reproduction in it's corresponding environment.

In the new environment, brown beetles can camouflage themselves from predators better than the green beetles and blue beetles can. This is because of the fact that brown color of beetle is a better phenotypic trait which favors the survival of brown beetles over green and blue color. Therefore, the survived brown beetles will reproduce and grow in number.

The diagram shows two cells. Identify structures C, D, and E and explain how they work together to perform a specific process wi

soldi70 [24.7K]

Structure C, D, and E in the diagram represent the endoplasmic reticulum, the ribosome, and the Golgi apparatus respectively.

When the ribosomes are attached to the endoplasmic reticulum, they give it a rough appearance.

The ribosome, endoplasmic reticulum, and the Golgi apparatus work together in the synthesis and transport of protein within the cell. In other words, they are all involved in the secretory pathway of cells.

The ribosome represents the actual site of protein synthesis.
The endoplasmic reticulum gets involved by folding the synthesized proteins and packaging them into secretory vesicles. Thereafter, the vesicles are transported to the Golgi apparatus.
The packaged proteins undergo further processing within the Golgi apparatus before they are exported to the cell membrane via the cytosol.

In other words, the 3 organelles work together to form the secretory pathway of the cell. They are involved in the synthesis, packaging, processing, and eventual transport of proteins to their target sites.
