Answer:
B
Explanation:
<em>The correct answer would be that in metaphase 1 twice as many chromosomes line up along the middle of the cell as in metaphase 2.</em>
Metaphase generally involves the formation of the metaphase plate and the alignment of chromosomes at the equator of the cell.
<u>At metaphase I, chromosomes align as homologous pairs as opposed to metaphase II where chromosomes align at the equatorial plate singly. It thus means that twice as many chromosomes line up at the equatorial plate in metaphase I when compared to metaphase II.</u>
The correct option is B.
The correct answer is Three germ layers. The feature, three germ layers, is only shown by higher invertebrates, as compared to lower invertebrates. The formation of the three germ layers is caused by the morphogenetic movement called Gastrulation.

Answer:
Longitudinal waves are waves that transfer energy parallel to the direction of wave motion.
Transverse waves are waves that transfer energy perpendicular to the direction of wave motion.
Explanation:
First of all, transverse waves are not mechanical waves at all. Longitudinal waves are mechanical waves.
Longitudinal waves are waves that transfer energy parallel to the direction of wave motion. A typical example of longitudinal waves is wave on a spiral spring.
Transverse waves are waves that transfer energy perpendicular to the direction of wave motion. A typical example of a transverse wave is light wave and other electromagnetic waves.
