Why are sinkholes one major environmental risk of underground mining? (1 point)
zheka24 [161]

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.

The inside of the barrel-shaped ldl protein consists of ___________ amino acids, while its outside portions in contact with the
Citrus2011 [14]

The inside of the barrel-shaped LDL protein consists of hydrophobic amino acids, while its outside portions in contact with the blood fluid consist of hydrophilic amino acids.

LDL is a type of lipoprotein, i.e., it contains protein as well as lipid (cholesterol). The full form of LDL is Low Density Lipid. LDL is considered to be the bad cholesterol for the body. It can cause diseases of the heart like heart attack or stroke.

Amino acids are the essential molecule that act as a monomer for the formation of proteins inside the body. They contain an amino group and  a carboxylic group attached to the same carbon atom. There are also a hydrogen atom and a variable R group attached to the carbon, also called the alpha carbon.

Golf courses make use of fertilizers to keep the grass green and healthy. Using your knowledge of osmosis, explain how applying
Nostrana [21]
Osmosis is the diffusion of water. Water tends to diffuse to the area with a higher concentration of solute. (Particles) In this case, Im assuming the fertilizer is the solute because it contains chemicals. Therefore, since water tends to diffuse to higher concentration of solute, the water in the grass will diffuse out to dilute the fertilizer on the surface of the grass. Without water, the grass will be dehydrated and shrivel up and die. Hopefully you find my answer helpful!

Which of the following statements is false? - DNA polymerase joins nucleotides in one direction only. - The leading strand of DN
stiv31 [10]

DNA replication proceeds in one direction around the bacterial chromosome.

Explanation:

Replication of DNA is preserved across most of life. Therefore, even bacteria DNA replication occurs bidirectionally. During replication of DNA, A primer is required in the initiation complex before DNA polymersae can begin replication. This is because this enzyme works by adding DNA nucleotides at the 3’ end of an existing strand. DNA can have several replication forks on one double strand in which replication occurs. For every fork, there is a leading strand whereby the replication process by DNA polymerase is continuous and the lagging strand whereby the replication is done in bits by the same polymerase enzymes. The lagging strand will, therefore, require many primers. This is becaue strands of DNA are antiparallel yet the DNA polymerase has to move in one direction. Since replication can only occur in the 5’⇒3’ direction, the antiparallel strand will be done in 5’⇒3’ chunks that will later be joined into one strand.
