D. Sensory neurons pass information about the stimulus to other nerve cells.
Answer:
ganglia are located in the sympathetic trunks, two long chains of ganglia stretching along each side of the vertebral column from the base of the skull to the coccyx; these are referred to as paravertebral ganglia.
Answer: The artery that bifurcates into the right subclavian artery and the right common carotid artery is the brachiocephalic artery
Explanation: The brachiocephalic artery which originates from the aortic arch divides into 2 branches
- right common carotid artery and,
- the right subclavian artery.
Answer;
-Krebs cycle
Explanation;
-The structure or organelle shown is mitochondria which is a power house to the cell, as it is where the process of cellular respiration takes place.
-Cellular respiration involves the breakdown of organic molecule such as glucose to yield energy in form of ATP which is usable to drive cellular processes and also can be stored for future use. The process takes place in three phases ; glycolysis, krebs cycle and electron transport chain.
-Following glycolysis, the mechanism of cellular respiration involves another multi-step process—the Krebs cycle, which is also called the citric acid cycle or the tricarboxylic acid cycle. The Krebs cycle uses the two molecules of pyruvic acid formed in glycolysis and yields high-energy molecules of NADH and flavin adenine dinucleotide (FADH2), as well as some ATP.
Answer:
The most likely explanation for the high rate of sympatric speciation that apparently existed among the cichlids of Lake Victoria in the past is sexual selection.
Explanation:
Divergent sexual and natural selection on the visual system has been confirmed earlier in sympatric, morphologically comparable sister species of Lake Victoria cichlids, but this seems not to reveal the exact morphological variations within them.
Cichlid fish reasonably describe the enormous inventory of standards of speciation and reproductive isolation without geographical or ecological separation.
Most of the recent observations have not confirmed the hypothesis, implying that sexual selection may be effective for the bursting cichlid speciation in the lake. Workroom practices have shown that reproductive isolation of three morphologically comparable species of rock-dwelling cichlid fish.
