I believe that Air moves from the larynx, through the Trachea, and then into the lungs. Trachea also known as the windpipe provides the flow of air to and from the lungs for cellular processes such as respiration. The lower respiratory system is made up of the trachea, larynx, the bronchial tree, the right lung and the left lung.
B and D. Earths axis is an invisible and imaginary line stuck in the middle of the earth. Kind of like stabbing an apple with a stick right through the middle. Then you spin that stick and the apple will spin.
Answer:
d.during only prophase I and involves exchange between chromatids of homologous chromosomes.
Explanation:
Crossing over is the event that occurs during the pachytene stage of prophase I of meiosis I and results in the formation of new gene combinations, that is, recombination. During pachytene of prophase I, the synapsed homologous chromosomes exchange the genetic segments between them.
To facilitate recombination, synaptonemal complex assists in pairing the homologous chromosomes together during the zygotene stage of prophase I. Zygotene is followed by pachytene. A cut in two non-sister chromatids of a homologous pair, exchange of the broken segments followed by ligation results in recombination. Prophase II does not include crossing over.
