Age of Sample (billions of years) Based on the sample set of data, which statement correctly identifies a weakness of the sampling technique?

Sample sites were not selected based on a range of crater densities.

Some missions took samples that were known to be of very different ages.

Samples were taken from both dark and bright lunar areas instead of concentrating on one area.

The missions did not sample craters on Earth, where rocks are more easily accessible for radiometric dating.

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.

they had the law tat factories that produces smoke cannot be built near residential buildings.

building of proper sewage system was done to ensure that the waste is carried away from the humans so that they do not get diseases from it.

also they built water systems to provide water in those areas which are drought prone.

i believe the answer is snake.

those characteristics are cellular organization, reproduction, metabolism, homeostasis, heredity, response to stimuli, growth and development, and adaptation through evolution. some things, such as a virus, demonstrate only a few of these characteristics and are, therefore, not alive
