Answer:
A. They have the same function
B. They have evolved independently
C. They indicate an evolutionary relationship
Explanation:
- Analogous structures are structures with a different embryonic but have evolved to perform similar function.
- <em><u>Analogous structures are a result of convergent evolution which is the independent evolution of similar features in species of different lineages or different embryonic origin.</u></em>
- Examples of analogous structures include; wings in flying animals like bats, birds, and insects, and fins in animals like penguins and fish.

Explanation:
We can easily move the box from a ground floor though to the first floor at an angle of 40° to the horizontal by simply pushing the load through an inclined plane. We will simply be lean the inclined plane on the building at the required angle and the push through the the height of the building.
Based on the explanation above, the best type of simple machine to use is an INCLINED PLANE. <em>Note that the essence of using a machine is simply to make our work easier and faster and also be able to overcome a much larger load with a minimal effort. </em>
Answer:
In normal cells, the cell cycle is controlled by a complex series of signaling pathways by which a cell grows, replicates its DNA and divides. ... In cancer, as a result of genetic mutations, this regulatory process malfunctions, resulting in uncontrolled cell proliferation.

Explanation:
According to National Geographic, ostriches are a part of a very small group of birds that cannot fly because unlike most birds, their small wings are not strong enough to carry their body for flight and their breastbone isn't balanced enough for flying. Birds that are unable to fly are called ratites.
A number of scientists namely Thomas Huxley, Richard Owen, and others have tried to show that these ratites are actually related to each other and eventually, it was discovered that they all had one thing in common, the way the bones at the roof of the mouth were arranged was similar to that of reptiles rather than other birds.
Richard Owen found and assembled the remains of an extinct ostrich skeleton which was an extinct moa and contrary to already held opinion, one ratite known as tinamous did not really fit with the profile of a ratite because it could fly, even though almost grudgingly and they possessed keeled sternum which suggests that they evolved from flying birds.
DNA tests showed that tinamous evolved within ratites and not necessarily as a separate entity. The tests also showed that moas and tinamous are related.
It was also speculated that the division of the supercontinent Pangaea southern side led to the separation of flightless ratite ancestors, causing each landlocked group to evolve and become the flightless birds we know today such as the ostrich, rheas, etc.
