Answer:
The correct answer will be option-neural tube, hindbrain, metencephalon,
Explanation:
The development of the brain during the embryogenesis takes place by the formation of a neural tube or the predecessor of the central nervous system.
The neural tube arises from the ectoderm layer of the gastrula where the anterior portion of the neural tube forms the brain.
The neural tube development results in the formation of three sacs filled vesicles in which the fist vesicle forms the forebrain, second forms the midbrain and the third vesicle forms the hindbrain.
Later development process divides the hindbrain into two new portions called metencephalon and myelencephalon where the metencephalon forms the cerebellum portion of the brain.
Thus, the selected order is the correct order.
Answer:
D. The banyan can grow in areas prone to hurricanes and typhoons because
the roots make the tree more stable in high winds.
Explanation:
According to this question, banyan tree posseses a unique characteristic in which roots grow down from its branches into the ground making the tree appear to have several trunks. This type of root is called STILT OR PROP roots.
The major function of this stilt roots is to provide additional support for the plant during adverse conditions. Hence, a major advantage that this root characteristic give the banyan tree over other trees is that it confers resilience upon the banyan tree, making it able to grow in areas prone to hurricanes and typhoons because the roots make the tree more stable in high winds.
The property called cohesion
Answer: a. Increasing the surface area for diffusion
Explanation:
When the air is inhaled through the nostrils, the air containing the oxygen the air diffuses inside the alveoli. The alveoli are the tiny sacs where air enters and exchange of gases takes place. From the alveoli the oxygen enters into the blood stream. The oxygen is utilized by the cells for respiration. The increase in network and number of the alveoli will increase the surface area for the diffusion of oxygen and hence, will speed up the respiration process.
