Answer:
<em>The number of chromosomes is maintained through the process of mitosis during asexual reproduction. </em>
Mitosis can be described as a process in which a cell divides and produces two daughter cells which are exactly similar to the parent cell. The chromosome number of the daughter cells will be the same as the parent cells. No crossing over or recombination occurs during this type of cell division. Hence, mitosis is an effective way to maintain the chromosome number of organisms which reproduce asexually.
As photosynthesis is a process that requires sunlight, the rate of this process will be 0 in a room without any light.
However, even if the dark room has very little light, it may still not be enough for photosynthesis to occur. This process requires certain levels of sunlight.
Explanation:
Isotherms are lines of constant or equal temperature. They are often used on weather maps by meteorologists to give a large scale view of temperatures across the U.S. If you have ever looked at a weather map in a newspaper, the isotherms are used to divide the color-filled temperatures.
The correct answer is: D. They are all peptides.
Mediators of inflammation released by certain type of cell have a function to control the later accumulation and activation of other cells. Chemical mediators of inflammatory responses are soluble, diffusible molecules that can act locally (at the site of tissue damage / infection) or at distant sites. These mediators include vasoactive amines and peptides, eicosanoids, proinflammatory cytokines. They respond to inflammatory process by preventing further tissue damage and ultimately resulting in restoration of tissue function.
Jellyfish do not have a central nervous system.
Squids which belongs to Cephalopoda (class of Mollusca) have the most complex nervous system of the invertebrates. They have well-developed senses and large brains. So, they are considered as the most intelligent of the invertebrates.
Dolphins, on the other hand, are regarded as one the most intelligent animal.
