The answer is shallow, warm, continental seas.
The Ordovician-Silurian extinction happened about 450-430 million years ago. Before the extinction, most multicellular organisms lived in the seas. It was a rich life in shallow, warm, and continental seas. The climate was favorable. Reef-forming corals, as well as the first true vertebrates, some fish, appeared. Trilobites and mollusks were diverse and rich. Green algae were common in the seas.
Answer: Attachment
Explanation: Infants tend to be attached to their parents. For good reason because the parents usually treat kids very well during infancy, and its the only thing the infants understand or know.
The effect of temperature or nutrition on the expression of genes are examples of how <u>the environment </u>can alter the phenotype.
Increases in temperature (warm environments) showed a non-significant increase in a phenotypic manner and a marginally significant increase in phenotypic variability. Larger increases in temperature noticed extra increases in phenotypic variability, but no increase inside the mean phenotypic response.
Usually, growing temperature induced an acceleration inside the improvement, and the higher the temperature, the sooner the expression reaction of any particularly focused gene. In more detail, larval yolk utilization and growth rates multiplied, while yolk utilization performance decreased with increasing temperature.

3rd one .. hope this helped :)
Answer: Pushing (compression) causes rocks to produce folds and faults. Like for instance when you are putting away a tent you have to fold it down to the proper size for it to fit back in it's box
