Dolphins originally leap out of the water to avoid predators like sharks. Dolphins also leap out of the water for navigation and to see where they are above the water. They also jump to get air since they are only mammals. Also for the entertainment of the public and also for occasional reasons... Hope I helped ^-^
If you need to know anything else about dolphins make sure to message me :P
The appropriate answer is D. Alfalfa. Alfalfa is a legume and these plants play a key role in the nitrogen cycle. These plants house nitrogen fixing bacteria on their roots. The bacteria are housed in tiny round structures of leguminous plant roots. Once the nitrogen is fixed in the soil it can now be used by other plants to make food. These plants include beans peas and peanuts. <span />
C is the answer because amplitude is need for wave 2 to be bigger than wave 1
The tumor should be found in d. amygdala
Amygdala is the center of human memory, decision making, and emotion function. The emotion function concludes the fear. A defect in amygdala can cause unexplained anxiety.
Amygdala is size is only like two pieces of almond in the temporal lobe. It is a part of the limbic system.
Answer:
knirps (a gap gene)
wingless (a segment-polarity gene)
kruppel (a gap gene)
even-skipped ( a pair-rule gene)
hunchback (a gap gene)
hedgehog (a segment-polarity gene)
Explanation:
The gap, segment-polarity and pair-rule genes play central roles in controlling embryonic development of arthropods. In the first place, the gap genes are associated with the formation of contiguous body segments, thereby mutations in these genes result in gaps in the normal body plan of the embryo. For example, in <em>Drosophila melanogaster</em>, mutations in the <em>knirps, Krüppel </em>and<em> hunchback</em> genes result in deletion of body segments. These genes are also known to regulate segment polarity genes, which determine the polarity of the embryonic parasegments by modulating Wnt and Hedgehog signaling pathways. Finally, the pair-rule genes work together with gap genes to control embryonic development of alternating body segments.
