Given:
Time: 3.5 hrs
Velocity: 120 miles/hour
Now Distance= Speed x Time
Now Velocity and Speed have the same magnitude. Velocity being a vector quantity has a definite direction. Where as speed is a scalar quantity, it indicates only the magnitude and doesn’t define any direction.
Hence Distance= Velocity x Time
Distance= 3.5x20=420 miles
<h2>
Answer:</h2>
Option C) All species with similar anatomical structures are related.
<h2>
Explanation:</h2>
- Homologous Structure: A homologous structure is an example of an organ or bone that appears in different animals, which are anatomically similar structure demonstrating descent from a common ancestor.
- All species with similar anatomical structures which means they have homologous structures and are related as they have evolved from a common ancestor.
- Homologous structures shows divergent evolution.
Result: Option C is the correct scientific inference for homologous structures.
C. prokaryotes do not have a well defined nuckeus
Answer:
Species that are broadly distributed are less likely to go extinct than those that occupy a small area or whose habitat is disjointed.
C. Genetic variation
Bacteria are very numerous, and random mutation of bacterial DNA generates a wide variety of change, including resistance. It happens through mutation and selection. Not only are they capable of sharing genetic bits of DNA to related and unrealted species they can develop ways to remove the antibiotic before it reaches its intended area via biochemical pumps or enzymes to inactiavte the antibiotic.
