Answer:
Because is the systematic observation, evaluation of facts and ideas
Explanation:
In scientific methods you have to find the problem, find solution experiment on it several times so that it will be accurate enough then you draw conclusion that is why scientists experiment several times to verify the solution
Answer:
Angiosperm
Explanation:
The mitochondria of flowering Angiosperm plant are the largest. The size of these mitochondria varies from 1.86 million bp to 2.4 million bp. It is also the most complex one as it carries large number of repeating units which allows multiple permutations for recombination. This allows generation of mitochondria of varying sizes with in the same species.
It is least gene dense as the inter regions are highly expanded. One of the most distinguishing feature of these mitochondria's are that they contain polypeptides. These polypeptides are basically non functional but have potential to evolve into functional one.
The Cambrian explosion. Trilobites were found because of their hard shell, unlike soft bodied creatures.
Answer: Resistance
Explanation:
Bacteria are single cell microbes that can be found in plant cells, animal, human body...They could be beneficial some are use for fermentation or harmful.
Over time, Bacterial have shown resistance and virulent to man by gaining resistance to antibiotics use to destroy there adverse effect in human system.
Some bacteria such as mycobacterium gonorrhoeae that causes gonorrhoea has shown medium resistance to antibiotics
Acinetobacter Baumannii causing pneumonia has shown a high level of resistance towards antibiotics making it difficult to reduce there effect. This has lead to more research on how this bacterial will be less virulent and harmful to man
