Answer:
Longitudinal
Explanation:
Longitudinal waves have the same direction of vibration as their direction of travel. This means that the movement of the medium is in the same direction as the motion of the wave. Some longitudinal waves are also called compressional waves or compression waves.
Answer: Option (D)
Explanation:
Early homo were capable of making stone tools, that are still found today, preserved in many museums.
They were basically used for the hunting purposes, hunting of animals but not as large animals like dinosaurs, as man never existed during the time of dinosaurs. These stone tools were used by them to hunt the smaller animals and cut their meat and also to protect from other harmful animals including the carnivores.
Thus, the correct answer is option (D).

Mitochondria produce energy in prokaryotic cells, while chloroplasts produce energy in eukaryotic cells. ... While the chloroplast get there food from the suns energy through the process of photosynthesis.
my guess is B. I am probably wrong
Answer:
See the answer below
Explanation:
<em>The problem with grouping organisms together taxonomically based on their physical traits is that organisms that not genetically or evolutionally similar would be grouped together. Grouping would be based entirely on superficial similarities instead of combining different features such as genetics, nutrition, the complexity of bodies, etc.</em>
Based on physical traits, for example, all flying organisms will be grouped together. Birds, flying insects, bats, etc. would be grouped together, whereas, they are quite different from one another when it comes to the complexity of bodies and other features. Even though some insects have wings and can fly like birds, insects have exoskeletons and birds do not, the body of birds is more complex than that of insects, and evolutionally, birds are more advanced than insects.
Hence, grouping organisms based on their physical traits only would be too superficial and not reflect the true relationships between organisms.
