The most likely explanation for the variation is the offspring were produced from different combination of genes. A single pair of gold fish mentioned in the question means a male and a female gold fish. The two of them mated and contributed different genes to the fertilized fish eggs, this results in production of various body shape and colouration which is known as variation.
Answer: Cerebrum
Explanation:
The primary sensory areas of the cerebral cortex receives and processes the somatosensory, visual, olfactory and gustatory information.
Then along with the cortical areas, the brain regions synthesize the sensory information into the perfections of the world.
It is the largest section of the brain which lies in the front or the top of the brain stem.
It is one of the five major divisions of the brain which is most developed.
The observation that indicates that it is a living thing that is multicellular because it has membrane-bound organelles. The correct answer is option B. Multicellular organisms' cells are macroscopic which are naked to the visible eye. These organisms are eukaryotic so this means that their cells contain membrane-bound structures.
<span>Age structure would help scientists determine if the problem exists with young or old dolphins.
The age structure shows the distribution of the ages of the individuals in a population. This not only shows the type of change taking place in the population (increasing, decreasing or staying the same) but also is able to help us relate problems to ages. By determining the which age group is more stressed, the scientists will be able to narrow down the causes of the stress and create more accurate hypotheses.
