Base your answer to the question on the diagram below, which represents a rock composed of cemented pebbles and sand Which change would most likely occur if this rock became buried deep within Earth's crust and was subjected to intense heat and pressure, but did not melt?
1
The density of the pebbles and sand would decrease.
2
The rock would become a plutonic rock composed mostly of quartz
3
The rock would become more felsic with a higher concentration of magnesium
4
The pebbles would become distorted and the sand would be recrystallized.

Invasive species are one of the major threats to biodiversity. these species multiply quickly and compete with native species for food, sunlight, spac and other resources. on the map, determine the area where native species will have limited resources available to them due to invasion threat from invasive species threat very low low medium high very high

Turtle hatchling survivorship rate is low in many turtle species due to predation. amanda researched the predatory rate on a species of turtle eggs in the red river. the eggs were harvested from trapped turtles and the egg's cloaca film (reproductive discharge) was either washed off or left on once gathered. research suggests that predators use the female's cloaca scent to locate the eggs. the eggs were only handled when wearing gloves and then reburied along islands where the turtles were trapped. the nests were monitored by cameras and manually on foot and data on nest predation were recorded. a. based on the experimental design, what is the dependent variable? b. based on the experimental design, what is the independent variable? c. based on the experimental design, what is the control?

Is there any solid scientific evidence that humans have been cloned?
