A shark and a dolphin have similarly shaped bodies and fins. However, these two organisms are not closely related: The shark is
a fish, and the dolphin is a mammal. Some species may have similar body structures even if they are not related because they evolved in:_______. a) similar environments and specific traits increased their chances of survival
b) similar environments and were exposed to factors that caused exactly the same mutations
c) different environments, but tried to adapt in the same ways so they could survive
d) different environments, but ate similar foods that affected their growth and development
A. similar environments and specific traits increased their chances of survival.
Explanation:
The shark and dolphins have similar body shape and fins. But shark is a fish and dolphin is a mammal.
Both of them are exposed to similar kind of environments. Both of them possess a specific kind of alternative characters and traits.
So, Some species may have similar body structures even if they are not related because they evolved in similar environments and specific traits increased their chances of survival.
I believe animals that possess homologous structures probably evolved from the same ancestor. Homologous structures are similar because of common ancestry. A homologous structure is an example of an organ or bone that appears in different animals, underlining anatomical commonalities demonstrating descent from a common ancestor.
a population of rabbits with alleles B and b, both alleles are present in equal frequencies p = 0.5 and q = 0.5 if 10 parents reproduce the probability of having an offspring with alleles B or b is 0.5; however, by chance, a slight difference in the offspring allele frequency might occur due ...
Why is the active site specific for only one type of substrate? Enzymes have a lock and key type fit so only a specific substrate fits in the activation site.
