it is a.cell because tissues, organs and organisms are larger than a cell so 'a' is the correct answer
Apes were basically monkeys. They walk on their hands and feet but crouched. There's a bunch of theories saying that humans evolved from apes. As apes evolved, they started walking upright.
Answer:
20 million years
Explanation:
If we have a neutral mutation rate of one mutation per 5 million years, then the total of eight mutation between the two different species would be 20 million years. This is because both species will have 4 mutations in those 20 million years, so combined, both by 4, will have 8 mutations between them. So few mutations on so much time will result in two species that are very similar to each other even after 20 million years of evolution, even making them hardly distinguishable, especially if it comes to defining fossil records from them both. A nice example of this are the members of the felidae (cat) family, which are all very closely related, and are almost identical, thus making it extremely hard to distinguish two species of the same or similar size by their fossils.
During exponential growth the rate of growth accelerates according the the number in the exponent of the base, which can of course vary depending on circumstance.
From a modern genetic perspective, this is defined as evolution.
