Answer;
-Fossil evidence
-Comparative anatomy
-Molecular clocks
Biological evidence of the age of the earth includes fossil evidence, comparative anatomy, and molecular clocks.
Explanation;
-Fossils are critical tools in science because they give us clues to the types of plants and animals that lived on Earth in the past.There are many examples of fossils found on separate continents and nowhere else, suggesting the continents were once joined.
-Comparative anatomy is an important tool that helps determine evolutionary relationships between organisms and whether or not they share common ancestors. However, it is also important evidence for evolution. Anatomical similarities between organisms support the idea that these organisms evolved from a common ancestor.
-Scientists can use relaxed-clock methods to deal with variation in the rate of the molecular clock. By measuring the patterns of evolutionary rate variation among organisms, they can also gain valuable insight into the biological processes that determine how quickly the molecular clock ticks.

Answer:
B. Enzymes generally catalyze only very specific biochemical reactions.
E. Most enzymes are proteins composed of amino acids
F. The cells of both eukaryotes and prokaryotes all contain enzymes.
G. If the active site of an enzyme is altered, the enzyme is unable to catalyze the biochemical reaction.
Explanation:
Enzymes refers to substances that acts as a catalyst in living organisms. They regulate the rate at which chemical reactions proceed without being altered in the process. Enzymes regulate the biological process that occur within living organisms.
Enzymes catalyze all aspects of cell metabolism such as digestion of food, conservation and transformation of chemical energy and the construction of cellular macromolecules from smaller precursors.
Application of enzymes
1. Industrial application
2. Medical application
1. Enzymes can be used for industrial application such as beer brewing, wine fermentation, bread leavening.
2. Enzyme can also be applied in the medical aspects for killing disease-causing microorganisms, promoting wound healing, and diagnosing some diseases.
Answer:
imaginary audience
Explanation:
Imaginary audience is a state in which an individual, most especially growing adolescent, are preoccupied with excessive and exaggerated belief and thought that they are the main focus of other people’s attention, and as such become worried unnecessarily and overtly self-conscious. The individual often feels they are the center focus of discussion of other people.
Answer:
Explanation:
Prokaryotic cells are very simple so they have:
circular chromosome
smaller than eukaryotic cells
lack nuclei
have cell walls
