The easiest example is of Pentadactyl limbs. This is the 5 bone structure of the 'arm' of different animals being similar, contributing to the explanation of common ancestors. Animals that have this are whales, horses, dogs, cows, birds and even humans. We each share the same five bones in similar places but with some of them changed to suit certain functions ie birds are more spread to support flying, while humans are made for throwing, picking up and holding things.
Answer: Sudden loss of habitat
Explanation:
Endangered species are animal or plant species that are in danger of going extinct.
This usually results from them suddenly losing their habitat and thus being exposed to unfamiliar conditions or threats that could end their existence. For instance, elephants losing their forest habitats in India and thus encroaching on farmland only to get shot for damaging farms.
The correct answer is: the treated glioblastoma cells were cultured in the presence of an inhibitor from umbilical cord stem cells, but the control cells were cultured without the inhibitor.
It has been shown that treatment with injected umbilical cord stem cells has strong therapeutic effects on glioma models. Those cells produce anti-tumour substances, with inhibitory effects.
Control group does not include the treatment in order to observe the treatment.
Answer:
The key elements of an amino acid are carbon (C), hydrogen (H), oxygen (O), and nitrogen (N).
Glucose is a hydrocarbon, so it contains carbon (C), and hydrogen (H). It also contains oxygen (O).
Nucleic acids are complex arrangements of carbon, hydrogen, oxygen, nitrogen, and phosphorous.
