Answer:
water is evaporated into the air then the water molecules get too heavy and come back down as snow/rain/ect
Yes there is because it is an animal cell
You should avoid using personally identifiable information.
The correct answer is: Free ribosomes are located in the cytoplasm, whereas attached ribosomes are embedded on the endoplasmic reticulum.
<span>Free ribosomes produce proteins which are released into the cytosol and used within the cell. On the other hand, attached (membrane-bound) ribosomes synthesize proteins that are needed within the plasma membrane or are released from the cell. The newly synthesized polypeptide chains are inserted directly into the endoplasmic reticulum by the attached ribosome and are then transported to their destinations where they will be secreted. </span>
Fossil evidence suggests that the tiktaalik had lungs, which meant that it could breathe in air, instead of just water.
This trait allowed the tiktaalik to survive despite the low oxygen content of the shallow water because the tiktaalik would simply get its oxygen from the air. This selective advantage was passed on to the tiktaalik's offspring and over time, more amphibious creatures evolved with the ability to survive both on land and in water.
