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.
The homology of animals is based on scientists current understanding on the evolutionary history of living species.
Answer:
TRUE!
Explanation:
Little red flying foxes are tree-dwelling bats. In daytime they can be seen roosting in giant camps that may include as many as a million individuals. The bats are indeed efficient fliers, as their name suggests, but time in the trees has also made them excellent climbers.
Answer:
C
Explanation:
Sugar, which is a product of the photosynthetic process of green plants can be converted to glucose (a simple carbohydrate). Enormous amount of these glucose molecules can be linked together to form a complex carbohydrate called cellulose, which is a polysaccharide because it is made up of a long chain of glucose molecules. The cellulose is ultimately used to build the cell wall of plants.
Anabolism is the production of a complex molecule by a living organism from a much simpler one. Since, cellulose is produced by the building up of glucose molecules, the process can therefore, said to be anabolic
Acetylcholine broken down is the process by which this neurotransmitter activates a suitable ligand-receptor to trigger a cell signaling pathway.
<h3>What is Acetylcholine?</h3>
Acetylcholine is a chemical messenger (i.e., a neurotransmitter) that is used to transmit signals inside the body.
Acetylcholine broken down is due to its hydrolysis, which ends cell signaling between brain synapses.
In conclusion, Acetylcholine broken down is the process by which this neurotransmitter activates a suitable ligand-receptor to trigger a cell signaling pathway.
