In cell biology, where does DNA replication take place?
mitochondria |
|
Golgi apparatus |
|
nucleus |
|
cytoplasm |
The cell nucleus contains the genetic material of the cell and is where DNA replication takes place.
The envelope of gases surrounding the planet is called the:
lithosphere |
|
geosphere |
|
atmosphere |
|
hydrosphere |
The biosphere is the global ecological system integrating all living beings and their relationships. This includes their interactions with the lithosphere (the rigid outer part of the earth, consisting of the crust and upper mantle), hydrosphere (all surface water), and atmosphere (the envelope of gases surrounding the planet).
Herbivores are __________ that subsist on producers like plants and fungus.
tertiary consumers |
|
scavengers |
|
secondary consumers |
|
primary consumers |
Primary consumers (herbivores) subsist on producers like plants and fungus. Examples are grasshoppers, cows, and plankton.
Secondary consumers that also eat producers are known as:
herbivores |
|
omnivores |
|
carnivores |
|
scavengers |
Secondary consumers (carnivores) subsist mainly on primary consumers. Omnivores are secondary consumers that also eat producers. Examples are rats, fish, and chickens.
During continental drift, the drifting plates move across which of the following?
fault lines |
|
liquid mantle |
|
water |
|
sediment |
The crust and the rigid lithosphere (upper mantle) is made up of approximately thirty separate plates. These plates more very slowly on the slightly more liquid mantle (asthenosphere) beneath them. This movement has resulted in continental drift which is the gradual movement of land masses across Earth's surface. Continental drift is a very slow process, occurring over hundreds of millions of years.
