Scientists can tell the average temperature of the earth by studying an ice core.
true
false

The given statement is true.

Explanation:

The given statement that is the scientists can determine the usual temperature of the Earth by reviewing an ice core is correct. By evaluating and studying the ice cores, scientists become familiar with the changing atmospheric levels of carbon dioxide, about the glacial-inter-glacial cycles, and the stability of the climate over the past 10000 years.  

It also allows scientists to determine the past modifications in both the atmospheric concentrations of greenhouse gases and temperature.  

hello there,

igneous rock formed from below the surface would have more crystals because

answer: because magma cools more slowly than lava

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
