Lll. a limited supply of necessary resources. If there isn't enough resources the species will have to learn to adapt to be able to gather the new food supply they need. Such as birds and there beaks, if the insects population went down and that was the main food supply for that type of bird they would have to be able to adapt in order to survive, so evolution occurs. Over time that bird would change to adapt to its new feeding source.
Hope this helps!
DNA contains the genetics . DNA tells the cells how to function
Answer:
Cryopreservation
Plant Vitrification Solution 2 (PVS2) and Plant Vitrification Solution 3 (PVS3)
Explanation:
Cryo-preservation or cryo-conservation is defined as the process of preservation of all cellular and structural elements such as cells, organelles, tissues, organs, or any other biological constructs by cooling to very low temperatures.
Two commonly used solutions in plants for this purpose are Plant Vitrification Solution 2 (PVS2) and Plant Vitrification Solution 3 (PVS3). Plant Vitrification Solution 2 (PVS2) is consists of, w/v, 0.4 M sucrose, 30% glycerol, 15% DMSO and 15% ethylene glycol and Plant Vitrification Solution 3 (PVS3) comprising, w/v, 50% sucrose and 50% glycerol.
Hence, the correct answer is "Cryopreservation
Plant Vitrification Solution 2 (PVS2) and Plant Vitrification Solution 3 (PVS3) "
Answer: Option D
Explanation:
A fossil can be defined as the imprint or plant or animal that is preserved in the environment which can be used to known the organism or environment at that time.
The fossil formation takes place when the organism is trapped in ice, trapped in sap or it gets buried in fine sediments at the bottom of the lake.
In these cases the animals dies and remains as it is to form fossil but if incase the animals is completely decomposed by the bacteria and fungi then it cannot be transformed into a fossil as there will be no remains left.
The correct answer is option D
Answer:
industrial wastes dumped into rivers
Explanation:
Because when factory and other industries dumped their wastes into water they begin to react on environment and fishes will die and that water or river smell so bad
