Water is one of the fundamental elements.
Answer:
The correct answer is "II. peroxisomes, I. mitochondria, and III. lysosomes".
Explanation:
The differences in organelles density are utilized for purification purposes, creating density gradients that helps to isolate each organelle separately. The correct order of organelles from most dense to least dense is: peroxisomes, mitochondria, and lysosomes. Peroxisomes have a density of around 1.19 g/ml, mitochondria of around 1.07 g/ml, and lysosomes of around 1.04 g/ml.
We will attempt to introduce a gene responsible for the resistance to the antibiotic ampicillin.
Bacterial transformation is a molecular technique widely used in genetic engineering. Its basis involves the introduction of a foreign DNA into a host organism. This will result in the expression of a foreign gene by the host bacterium. In this example, our host organism is a bacterium who is sensitive to the antibiotic ampicillin. By introducing a gene for resistance to this antibiotic, the bacterium will become ampicillin resistant.
Answer:
Radioactive isotopes has a characteristic half life that is ranging from less than a second to million of years.
Explanation:
One of the characteristics of radioactive material is that the radio active isotopes instantly gives off particles. This process is termed as radio active decay.For this activity pennies are used pennies headed up it means that nuclei have undergone radio active decay, or tails up it means that nuclei that haven't yet decayed.
