Answer:
TRUE
Explanation:
The Sauropods were the enormous herbivore dinosaurs that had a long neck and a tail, but the size of their head was relatively small. The fossil remnants of a previously existed unknown sauropod dinosaur species named 'Tataouinea hannibalis' were obtained from the rocks of the southern side of Tunisia.
From the fossil evidence, it was observed that a sizable opening was present in the ischium, which actually opens into a large air chamber. This observation supported the theory that considers the presence of abdominal air sacs in this type pf dinosaur species that are similar to the respiratory system of Aves (birds).
Thus, the Sauropods and Aves are closely related to one another.
Hence, the above statement is TRUE.
False
<span>Marine ecosystems like lakes and oceans have aphotic zones. Aphotic zones refer to the zones in the water where there is little or no sunlight. It is found in bodies of water were depths only receive less than 1% of sunlight penetrations. Bioluminescence is essentially the only light found in this zone and most food comes from dead organisms that sink at the bottom of lakes or oceans. </span>
The answer would be a mantle
Answer:
Epinephrine binds to receptors on some smooth muscles (ex: around arterioles) → Ca++ released from ER → intracellular Ca++ up → stimulates contraction. c. Epinephrine binds to receptors on some smooth muscles (ex: around bronchioles) → phosphorylates protein needed for response to Ca++, preventing response.
