Answer:
To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date ancient events.
Explanation:
Answer:
The correct answer is option b. "Glucose is a highly reduced compound, containing many carbon-hydrogen bonds and a lot of potential energy".
Explanation:
Glucose is the preferred source of energy for many microorganisms, including most bacteria. The reason behind this adaptation is that glucose is a highly reduced compound, containing many carbon-hydrogen bonds and a lot of potential energy. Reduction of glucose is achieved through different metabolic pathways using enzymes as aldehyde reductase, and its carbon-hydrogen bonds breakdown releases a lot of potential energy. These two properties makes glucose a good source of energy for the cells.
Answer:
The DNA enzyme; Helicase
Explanation:
DNA chains are "unzipped" by the enzyme Helicase; which requires energy to function
Answer:
1. warm blooded, 2. breast feed its young
Explanation:
Whales are warm blooded, which means they keep a high body temperature that does not change in the cold water. Fish are cold-blooded, so their body temperature changes depending on the temperature of their environment. AND hales are other mammals that feed their young milk too, although it takes plenty more to feed them than human babies
