No, cells are very complex. They are composed of highly specialized organelles that each have different functions.
Answer:
The answer is:
D. the radiation of herbivores such as grazing animals
Explanation:
Oligocene and Miocene Epochs:
- The Oligocene epoch is characterized by temperate and subtropical climatic conditions which favored the expansion of grasses and reduced forest cover.
- The Miocene epoch, which succeeded the Oligocene era, is attributed to changes in global circulation due to global warming of the climate followed by global cooling towards the end.
The Oligocence and Miocene epoch are both attributed to the expansion of grasslands and savannah. Both eras marked rapid and drastic evolutionary changes in grazing mammals and herbivores. Diverse groups of grazing mammals lived throughout these eras. For example, the largest herbivore and land mammal of all time, <em>Indricotherium</em> (a sort of giant hornless rhinoceros), was present in the Oligocene era.
Similarly, the Oligocene era in North America favored the rapid radiation of primitive horses.

Answer:
Anterior end
Explanation:
You have a pretty good shot at guessing this, because the earthworm has very little going on at the posterior end except the anus. And you probably saw this in lab, too.
I've attached a picture of the earthworm anatomy. Worms can't smell in the strictest sense, but they can use their receptors as kind of a combo smell-taste thing, and those are located in the anterior end.
Answer:
During the development of the fetus, the mechanism by which the mammalian skeletal system gives rise to tissues of the bone is termed as endochondral ossification. Endochondral ossification also plays an essential role at the time of the development of the long bones length, rudimentary generation of the long bones, and healing of bone fractures naturally.
The following are the steps in the process of endochondral ossification:
f. The development of the cartilage model.
b. The calcification of cartilage takes place and the formation of bone collar occurs.
a. In the diaphysis, the formation of the ossification center takes place.
c. In the epiphysis, the formation of ossification centers takes place.
d. Replacement of cartilage takes place by the bone.
e. Ossification of epiphyseal plates takes place.
