Sinkholes one major environmental risk of underground mining because, Underground mines may collapse after mining is complete, which causes sinkholes.
<u>Explanation:</u>
The movement that occurs on the surface of the ground is known as mine subsidence. This is mainly caused due to the collapse that happens in the cola or any clay mining works that occurs in the underground surface. When anything is extracted form the underground surface, some holes are made in the underground surface which are sinkholes.
The damages that are caused as a result of this can be claimed by Mine Subsidence Insurance Policy. This type of underground mining is very dangerous as it give rise to the formation of sinkholes. This is forms when there is collapsing of the surfaces in the underground occurs after the completion of the mining work.
Answer:
A cell that has duplicated chromosome cannot be in<u> G1 phase.</u>
Explanation:
- G1, G2 and S phase are the divisions of the interphase i.e. the resting phase of the cell cycle.
- A cell cycle has two phases; interphase and M-phase.
- During interphase the cell grows and in M-phase it divides.
- G1 is the Gap between the M-phase and the S-phase.
- G2 is the gap between the S phase and M phase.
- DNA replication is confined to the S part of interphase.
- Since G1 phase comes before the S phase , we can say that a cell that has duplicated chromosome cannot be in G1 phase.
Pasteurizing milk involves exposing milk to high temperatures for a short period of time to destroy all harmful bacteria that might be lurking in the milk. It is beneficial as it kills most harmful bacteria.
The correct answer is (b.) an increase in the width of the stem. The increase in the width of the stem could be referred to as the secondary growth of the stem. Whereas the primary growth is the upward growth of the plant.
Meiosis produces haploid gametes, where as mitosis produces somatic cells. meiosis involves two divisions, mitosis involves only one division. mitosis produces genetically identical daughter cells, meiosis produces genetically unique daughter cells.
hope this helped, God bless!<span />
