VladimirAG [237]

Answer:

The options are :

The spaces get wider because the concrete sections shrink.

The spaces stay the same because the concrete sections does not shrink or expand.

The spaces get narrower because the concrete sections expand.

Some spaces get wider, some spaces get narrower, and some spaces stay the same because each concrete section behaves differently on a hot summer day.

The answer is

Some spaces get wider, some spaces get narrower, and some spaces stay the same because each concrete section behaves differently on a hot summer day.

Concrete surfaces react with a change in temperature by either shrinking or expanding depending on the temperature difference.

When there is an increase in temperature it expands a bit and shrinks a bit too when the temperature is decreased.

1. Flowering plants and bees have influenced each other's evolution, providing an example of
Doss [256]

Answer:

1. coevolution

2. abiogenesis

3. Endosymbiont Theory

4. It's estimated that over 99 percent of the species that have existed on Earth at some point in time are extinct today.

5. Coevolution implies that the evolution of one species is dependent on and works in relation to the evolution of another species. This may cause positive or negative impacts and could be beneficial to both organisms or only to one.

6. This theory states that the first building block of life that allowed for reproduction of organisms was the development of self-replicating RNA. This hasn't been able to be fully demonstrated in any science experiment but is based on the idea that there are RNAs that can catalyze biochemical reactions on their own without proteins.

7. This process points to the development of structures through the envelopment of smaller cells that perform specific functions. This is how eukaryotic cells evolved from prokaryotic cells.

8. This experiment was important because it showed that, in the right primordial soup, organic compounds could develop from inorganic compounds.
