Im not really sure , but it might have something to do with polar chemical compound <span />
Answer: Solution in Water
Explanation:
I believe this refers to the reaction between Zinc and Hydrochloric acid.
When this happens, the solution will be Zinc Chloride but as it happened in a solution (the acid), the resulting Zinc Chloride salt would be in aqueous form which means that it would be a solution in water which is the other product of this reaction.
Had the zinc reacted with gaseous HCI, it would have resulted in a Zinc Chloride with no liquid in it.
Answer: I believe it is Thigmotropism.
Answer:
basale - spinosum - granulosum - lucidum - corneum.
Explanation:
The order of strata in the epidermis:
- Basale: it is the deepest stratum. It has one layer of cells called keratinocytes, which are stem cells for the epidermis.
- Spinosum: The keratinocytes in this layer have spiny shapes. They synthesize cytokeratin and lipids. In this layer, we can also find macrophages.
- Granulosum: The keratinocytes of the previous layer ascend and synthesize keratohyalin, which is in granules. The keratohyalin helps to join keratin filaments. Also, the cells release the lipids synthesized in the previous layer, and they form a barrier that stops dehydration.
- Lucidum: it is only on thick skin, like the one in the sole of the feet. The keratinocytes in this layer have expelled the nucleus and now are dead cells. The keratinocytes have a flat shape and form a thin layer.
- Corneum: it is the most superficial layer. It is made of dead keratinocytes filled with keratin in their cytoplasm. It is a thick layer that suffers desquamation when new dead cells filled with keratin ascend from the previous layer.
