A red Corvette is traveling down Broad St. At 45mph. The speeld limit is 25 mph. The car is captured on camera speeding, how man
nexus9112 [7]

Answer:

The answer is 20 mph

Explanation:

This question is more technical than it is of actual calculation. The car was travelling at a speed of 45 miles per hour when the actual speed limit that should be observed is 25 miles per hour. His excess speed can be calculated as

45 mph - 25 mph = 20 mph

Thus, the car was travelling at a speed of 20 mph more than the actual speed limit of the road which is 25 mph

Even though the limbs are used for different purposes, all the organisms show a similar arrangement What does this evidence tell
Snezhnost [94]

Answer:

It tells us that homologous structure is evidence of common ancestry

Explanation:

<em>Homology is the similarity of organs of different organisms even though they perform different functions in the organisms. Organs that are built on a similar plan but perform different functions are known as homologous organs. </em>

Organisms having organs built on a similar plan is an indication that they were once from the same source and adapting to different environments must have been the reason the organs evolved for different functions.

For example, all mammals have limbs that are built on a similar five-digit plan even though limbs are adapted for different functions in different mammals.

Explain why multicellular organisms require a ventilation system??
Anuta_ua [19.1K]
Ventilation maintains a steep concentration gradient, blood at the exchange surface usually has lower O2 and higher CO2 content than the air (of for fish, the water) at the exchange surface. This is what allows for diffusion of O2 into the blood and CO2 out of the blood. Multicellular organisms have a greater number of cells so will have a higher energy demand than single cellular organisms, this demand can only be met by allowing the cells to respire, a ventilation system brings oxygen molecules which are a raw product of respiration into the hemoglobin of the blood to be transported to tissues. As surface area : volume ratio is very low so if there was no ventilation system and the organism instead relied on exchange of materials through the exposed skin it would be very difficult to met the high energy demand as less O2 and CO2 would be able to be exchanged.
