Birds, unlike mammals, do not have separate exits for urine and feces. Both waste products are eliminated simultaneously through the cloaca. While mammals excrete nitrogenous wastes mostly in the form of urea, birds convert it to uric acid or guanine, which reduces water loss in comparison.
Bacteria move using a tail like structure called flagellum .
Explanation:
- <em>Permian Triassic Extinciton</em>
Lots of places were affected, extinction; in species, vertebrates, etc, etc.
- <em>Devonian extinction</em>
Extinction-- in marine species...
Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption. They also contain lots of mitochondria , which release energy from glucose during respiration in order to provide the energy needed for active transport.
Hope this helps, have a nice day!:)
