how many years ago did humans and orangutans share a common ancestor?
1 million years ago
20 million years ago
12 million years ago
7 million years ago
lobe-finned fishes - ✅✅ -Which group of fishes includes a lineage that migrated
out of fresh water and adapted to life on land?
lobe-finned fishes
cartilaginous fishes
jawless fishes
ray-finned fishes
flatworm - ✅✅-The figure below shows a planarian. Bilateral symmetry and a
highly branched gastrovascular cavity all suggest that the planarian is a(n)
______.
, flatworm
They all have a notochord sometime during the life cycle. - ✅✅-Which of the
following is a characteristic of all chordates?
They all exhibit radial symmetry.
They all have a notochord sometime during the life cycle.
They all have an exoskeleton sometime during the life cycle.
They all have vertebral columns.
habitat loss - ✅✅ -Birds are a widespread group of animals, with approximately
10,000 different species found throughout the world today. Because they are
relatively easy to find and so visually appealing, they have been studied more
thoroughly than many other groups of animals. They are also valuable biological
indicators, because many species live in different habitats during different times
of the year and cover long migration routes. According to the World Conservation
Union, extinction threatens over 1,200 bird species today and at least 179 are
critically endangered. Some of the most endangered species include the Tahiti
monarch, with only 10 pairs remaining, and the Bali starling, with only 12 wild
individuals left. In Hawaii, the last captive po'ouli died in 2005 and the last two
known to be alive in the wild have not been seen in many months. Common birds
are also disappearing. In North America, red-winged blackbird population
annelid - ✅✅ -The legless, segmented body of the animal below suggests that it

roundworm
snake
annelid
arthropod
Cnidarians - ✅✅ -______ are characterized by stinging cells used for defense
and for capturing prey.
Sponges
Cnidarians
Annelids
Roundworms
radial - ✅✅-What type of symmetry does this organism exhibit?
binomial
asymmetrical
