What was a mining process that removed large quantities of earth.
jasenka [17]

Answer:

Open-cast mining

Explanation:

The aftermath of open cast mining are pits (called quarries) on the surface of the earth where the surface soil has been removed/ displaced to access the mineral deposits that are just close or at the surface of the earth. This type of mining results in environmental degradation because they disturb the biodiversity of the ecosystem in which the mining is taking place. Rehabilitation of the area is required after the mining has been exhausted to restore the initial environment.

The ability to curl one's tongue into a U-shape is a genetic trait. Curlers always have at least one curler parent but noncurler
irina1246 [14]

Answer:

A noncurler has a genotype cc.

Explanation:

If curlers always have at least one curler parent, it is possible being "curler" will be related to a dominant allele, in this example, "C".  So, being "noncurler" could be a recessive trait. Noncurler can have one or both parents who are curlers, and this is concordant with a recessive inheritance if both parents are heterozygous (Cc) (with a probability of 25% of being "noncurler"). Also, it is possible if one parent is heterozygous and the other is homozygous for c (Cc x cc), this with a probability of 50% ob being "noncurler".  

The Punnett square shows this clearly.
