It can lead to multiple health hazords like harmful substances and it has a huge waste of rocks and vegatation.
Explanation:
Across the world, mining contributes to erosion, sinkholes, deforestation, loss of biodiversity, significant use of water resources, dammed rivers and ponded waters, wastewater disposal issues, acid mine drainage and contamination of soil, ground and surface water, all of which can lead to health issues in local areas. Some mining methods may have significant environmental and public-health effects.
The horse will give 32 chromosomes and donkey will give 31 chromosomes to the offspring.
The offspring has 63 in total.
It is odd so it can not produce normal germ cell. So it is sterile.
There is a 1:4 chance of getting JjQq. The parent JjQq can produce four genotypes: JQ, Jq, jQ, and jq. the parent JJQq can produce two genotypes: JQ and Jq. When we do a punnett square:
JJQQ, JJQq, JjQQ, JjQq,
JJQq, JJqq, JjQq, and Jjqq
There are two JjQq.
Two out of eight is one out of four.

Answer:
The statement that says " The mitochondrion contains a circular chromosome that has bacterial DNA sequences" is true among the all statement given above.
Explanation:
The Endosymbiotic theory that is other wise known as the symbiogensis illustrates the occurrence of the eukaryotic cell from the prokaryotic cells. Mitochondria and plastids are the most studied example in support of this theory. This theory explains that the aforementioned organelles are formed as they are taken inside in one another by the prokaryotic cell. Some of the evidences in support of this theory are mentioned below:
- Phylogenetic similarity between the mitochondria and chloroplast to the proteobacteria and cynobacteria respectively.
- Ability of these organelles to divide only through binary fission as the bacterial population.
- The associated ribosomes are similar to the bacterial ribosomes.
- Presence of porins in these organelles similar the bacterial membrane.
