Romashka-Z-Leto [24]

Answer:

I found this from someone else. This is not my work, Also if this does not answer the question ask the question on here and you can see more answers. hope this helps.!

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.

The cell membranes begin to come apart when there is insufficient water around the cells. The cytoplasm of the cells becomes more concentrated, which slowly poisons the cells. The cell walls become brittle as they dry out, and some of them collapse. The central vacuoles in the cells lose water and can no longer help support the cells.

You can measure and describe climate by walking out the door and describing current atmospheric conditions. true or False
Xelga [282]

Answer:

The answer is "False."

Explanation:

The sentence above is stating that you can<u> "measure"</u> and describe climate by "walking out the door and describing current atmospheric conditions." This is "false" because climate cannot be measured by qualitative descriptions or subjectively. Measuring it entails quantity which is objective in nature. An example of this is by using "thermometers" or "rain gauges."

Although you can describe the atmospheric condition or the climate just by walking out the door,<em> you can never measure it.</em>

Thus, this explains the answer.
