A star is formed within the clouds of dust. These clouds of dust are scattered throughout the galaxy. These dust clouds are called as nebula. The turbulence inside the dust clouds rise to form knots. These knots along with sufficient mass causes gas and dust to collapse with the help of gravitational force. These sequence of steps leads to form a star.
The answer is; B
During metaphase I of Meiosis I , homologous sister chromosomes line up the metaphase plate in pairs. During anaphase I, the sister chromosomes of the pairs are separated and move to opposite poles. This way, the resulting daughter cells have half the chromosome number as the parent cell.
As blood glucose returns to its baseline level, the levels of insulin and glucagon in the blood will stabilize. As the blood glucose levels begin to drop below the base line, the concentration of glucagon hormone increases. while as the blood sugar levels increases above the baseline, the level of insulin hormones increases. Insulin and glucagon work antagonistically to maintain the normal level of glucose in the blood.
Answer:
The increased activity prior to the saccade reflects a shift in attention to the stimulus inside that neuron's receptive field.
Explanation:
They observed that the neurological basis of attention, first made in the superior colliculus has been extended to a number of areas in both the dorsal and ventral streams.
Would this be speciation?
