Answer:
radioactivity will not be able to tell the difference between the DNA and proteins
Explanation:
It seems that the experiment will fail to show what Hershey and Chase showed because they modify some of the aspects. These modifications will cause changes to the results, the main one being that radioactivity will not be able to tell the difference between the DNA and proteins. This is because Amino Acids are proteins that also contain nitrogen atoms, thus labeling the nitrogen would include all DNA and proteins. This being the main reason why Hershey and Chase decided to label the DNA instead.
Answer:
Quickly
Explanation:
The more quickly that a new generation of organisms develops and reproduces the faster that you will be able to observe whether the new traits have been passed on to the new generation or not, and so on if you want to see this effect over several generations. For example, if you have genetically modified corn, you just have to wait one year to see if next year's generation of corn will have the modified trait or not. Conversely, if you geneticall modify an apple, you have to wait several years until the new generation of apples mature and are able to flower and produce the next generation of apple embryos.
Answer: The main cause of the extinctions is the destruction of natural habitats by human activities, such as cutting down forests and converting land into fields for farming. Due to human activities, populations of many species have become small and isolated.
Explanation:
The exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. As shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.

Answer: It is a physical change.
Explanation:
Even though they make sand which they are still meat bread and cheese. The reactants stay as there ware even though they have taken a different form. It is like boiling water or freezing it. They look different but the reactants stay the same.
