There are two phases of cell division, the <u>mitosi</u><u>s</u> and the <u>meios</u><u>is</u> phase. During interphase, the cell does <u>not split</u> ; it merely grows. Mitosis is the type of cell division that produces <u>two</u><u> </u><u>identical</u><u> </u><u>cells</u> with the same number of chromosomes. Mitosis is divided into four stages namely <u>prophase, metaphase, anaphase, </u>and<u> telophase</u><u>.</u>
No, heterotrophs do not covert solar energy into chemical energy. Heterotrophs are organisms, like humans, that find their own food. They can not physically make their own food because they can't use the process of photosynthesis. So, heterotrophs hunt or gather their own food.
<u>Controlling disease in commercial fisheries</u>
Explanation:
Disease outbreaks among fishes reared lead to economic loss to the fish farmers. Optimal conditions of the pond should be maintained to prevent disease spreading.
Control of disease is very challenging because fishes are cultivated in aquaponds at high density which increases direct contact among fishes making way for spread of the disease.
Natural predators will remove infected fish quickly but manual methods are time consuming and not effective.
Various steps which can be followed for prevention of diseases like good water quality, nutrition and sanitation facilities, stocking and storing of fish, recording each detail.
At the same time, disease control can easily be done by reducing the density of the stocks, application of vaccines and antibiotics and other drugs, mechanical administration of drugs, use of probiotics etc.
