Why do babies have more bones than adults? Why are some animals cold-blooded? Why are wetlands important to amphibians? Why can't cold-blooded animals produce heat? Briefly describe the ways desert reptiles conserve water. Why do humans have to learn to swim while other animals can do it ...
The complexity of multicellularity is contradictory to regeneration and that’s why humans cannot undergo regeneration. However, Planarians which are a group of free-living flat worms, can undergo regeneration. This is supported by the fact that Planarians’ have a simpler and the ability to form...
Humans have changed the continent's biosystem greatly, as massive forest areas and formerly huge populations of certain animals have reduced to bits and pieces, if even that. However, North America continues to absolutely mop the floor with Europe when it comes to the sheer richness of its anim...
It’s actually the remnant of a third eyelid. Known as the “plica semilunaris,” it’s much more prominent in birds and a few mammals, and functions like a windshield wiper to keep dust and debris out of their eyes. But in humans, it doesn’t work. It’s vestigial, meaning it no...
the colony, they do not directly reproduce. Instead, they delegate this task to the queen. This strategy hinges on the shared genes among colony members. When the queen reproduces, she passes down genes not only of her own but also of those who share genes with her. So, everybody gains...
reproduce and achieve dominance and status. But it is tiring, so when you have an older body, it might be nice to stay with what is familiar and comfortable. Decreasing energy levels might equally play a role in humans. In addition, [Stanford researcher] Robert Sapolsky found that g...
Why do humans need food energy? Why are top predators important in biodiversity? Why are sweat glands important? Why are fish so important to the evolution of other vertebrates? Why is it helpful to have lots of villi? Why is biodiversity important for an ecosystem?
If the crop plants hybridize and reproduce with weedy relatives, then this herbicide-resistant gene will be [#highlight6]perpetuated[/highlight6] in the offspring. [#insert1] In this way, the resistant gene can make its way into the weed population. [#insert2] If this happens, a farmer...
they were born to lay their own eggs. Salmon swimming upstream is both a form ofmigrationand a way to ensure that their young survive long enough to hatch and grow into adults. The journey is challenging but leads to the successful salmon populations that animals and humans depend on for ...
Why do animals have tails? Why is a siamang considered an intelligent species? Why is animal intelligence difficult to define? Why do humans have to learn to swim while other animals can do it from birth? Why can't dogs talk? Explain real-world examples of why the classification of anim...
