D. Mitosis involves only one division, while meiosis involves two divisions.
Mitosis --> Two identical diploid daughter cells from one division
Meiosis --> Four unique haploid daughter cells from two divisions
The littoral zone is also known as the intertidal zone is the place where the land and sea meet and is found between the low and high tide zones. This diverse marine ecosystem is witnessed along the coastlines globally. It comprises ample nutrients and oxygen and is considered home to numerous species.
The littoral zone is further differentiated into vertical zones, like the spray zone and low tide zone. Spray zone also known as the upper littoral, and is dry in the majority of the time, but sprayed with water at the time of high tides. It gets flooded at the time of extreme high tides and storms.
The low tide zone also is known as the lower littoral zone, is generally found under water and gets exposed when the tide becomes abnormally low. The species in this zone are not well used to extreme temperatures and long duration of dryness.
Some of the common organisms found in both spray and low tide zones are isopods and limpets.
Answer:
3. detection and response to stimuli
Explanation:
According to the given information, the thermoreceptors present in the skin layers of dogs and cats sense the change in the temperature of surroundings. When the temperature is reduced during a cold day, the sensory information about the same is sent to the central nervous system which in turn sends the motor information to the related muscles and glands.
One such response towards the lower temperature conditions is an expansion of their skin coat layers to insulate the underlying tissues from the cold surroundings. The same response (expansion of skin coat) is produced when these animals sense the danger of the presence of large predators around them.
