Vitamin B12 is mostly found in animal-based food.
Vitamin C is found in abundant in plant-based food.
Explanation:
Vitamin B12 also called cyanocobalamin is obtained only from animal-based foods like fish, meat, egg and dairy fruits. Vitamin B-12 is helpful in the maintenance of nerve cells and blood cells. It is required to prevent certain types of anaemia, also an integral part of DNA formation.
Vitamin B12 is a fat-soluble vitamin. Vitamin B1 is found in animals because animals like cows store the vitamin from their gut bacteria and eventually passed to the ones consuming them.
Vitamin C is a water-soluble vitamin found in mainly citrus fruits. These are required for the formation of skin, tendons, collagen and cartilage. It is also helpful in maintenance of bones and teeth. It helps in the repair of skin.
Vitamin C is produced in plant cells by biochemical pathways because it needs them as coenzyme and oxidants for their growth.
Answer:
The correct answer is conservative model.
Explanation:
There are 3 hypothesized DNA replication models: semi-conservative, conservative and dispersive model (see figure). Heavy isotope of nitrogen makes diference when density gradient centrifugation experiment conducted and two diffent bands contaning different isotopes of nitrogen are observed. With one band only containing 14N means bacteria only copies one strand in one replication which supports semi conservative model.
They live about 2 weeks to 3 weeks I think and they probably would die in 4 days.
Answer:
Explanation:
Environmental changes occurs from time to time, we have the short term changes that do not last for a very long time and the long term changes that last for a while. Accumulate of short term changes can extend to long term as some of the long term effects are as a results of short term changes in the environment.
Short term environment changes can be favourable to some organism and adversely affect others. Raining season causes increase in growth and development of most plant species but a long period of drought and dryness makes its hard for some plant to strive while some plants can strive well in long period of drought. This makes the two changes different, the both have individual effects on plants response.
Bacteria exposed to DNA can incorporate the DNA and change phenotype.
Hope this helps.
Have a nice day.
