Answer:
The components of he respiratory system conduct air to the lungs ,such as the trachea (windpipe) which branches into smaller structures called Bronchi . The process of breathing (respiration) is divided into two distinct phases , inspiration (inhalation) and expiration (exhalation).
Explanation:
From cells to tissues to organs to organ systems to the organism itself. That is the hierarchy of cytology to most eukaryotic organisms. Cell is the basic unit of every living organism. This basic unit has specialization that functions differently for each pattern of structural and functional processes.
Binary fission is a form of asexual reproduction used by members of domains archaea and bacteria among other organisms. Like mitosis (in eukaryotic cells), it results in cell division of the original cell to produce two viable cells that can repeat the process. Hope I’ve helped ;)
Answer:
A tan might indicate sun damage to the skin.
Explanation:
Tanning is the process by which the skin is exposed to the ultraviolet rays that comes from the sun with the purpose of producing a dark-brown coloration called a TAN.
A tan achieved by exposure to the sun can actually indicate that a person's skin is undergoing damage from the UV rays of the sun, hence, the skin responds by producing a protein called melanin, which protects the skin and later forms the dark coloration- tan. From this explanation, tan is got in response to a damaging signal received by the cell, hence, a tan might indicate sun damage to the skin.
