Answer:

The a cell divides, it is important that each daughter cell receives an identical copy of the DNA. This is accomplished by the process of DNA replication. The replication of DNA occurs during the synthesis phase, or S phase, of the cell cycle, before the cell enters mitosis or meiosis.

Answer:

The double-stranded parent DNA molecule gets separated and provides two template DNA strands for daughter strands synthesis. Enzyme DNA polymerase adds nucleotides complementary to template strands and synthesize daughter strands.

The reason that there are Okazaki fragments during DNA replication is ultimately because:

rusak2 [61]

Answer:

B) Polymerases can only synthesize in the 5' to 3' direction

Explanation:

The leading strand's directionality is 3' to 5', so polymerase has no problem with replicating this one. But the lagging strand has the opposite directionality, so the polymerase must work in the opposite direction of the replication fork.In consequence, the replication process undergoes periodic breaks, and the enzymes have to stop and start again while helicase separates both strands, resulting in the polymerization of okazaki fragments.

What is an advantage that exotic species have when introduced to a new habitat

Bumek [7]

Other than contributing to potential increase in diversity of species in an ecosystem, exotic species have positive benefits like removing toxins from the soil, regulating erosion, and controlling undesirable species.

Rocks and Minerals as Resources Lab Activity

exis [7]

Mining is the birth of minerals and other geological accouterments of profitable value from deposits on the Earth.

Mining negatively affects the terrain by converting loss of biodiversity, soil corrosion, and impurity of face water, groundwater, and soil. Mining can also spark the conformation of holes. The leakage of chemicals from mining spots can also have mischievous goods on the health of the population living at or around the mining point.
In some countries, hidden-trapping companies are anticipated to cleave to recuperation and environmental canons to ensure that the area hidden-trapped is ultimately converted back into its original state. still, violations of similar rules are relatively common.

Loss Of Biodiversity

frequently, the worst goods of mining conditioning are observed after the mining process has desisted. The destruction or drastic revision of the pre-mined geography can have a disastrous impact on the biodiversity of that area. Mining leads to a massive niche loss for a diversity of foliage and fauna ranging from soil microorganisms to large mammals. Aboriginal species are most oppressively affected since indeed the fewest dislocations in their niche can affect extermination or put them at high threat of being wiped out. poisons released through mining can wipe out entire populations of sensitive species.

legislation related to mining-

There are different kinds of legislation. The legislation that needs land to be restored after mining tends to make mining to be veritably precious as it does so through the duty of some rules and regulations for the hidden-trapping companies.

Through this, it handles the responsibility of their land declination and takes back the land to its original form. This process is known to contribute to the fiscal counteraccusations of a company.

Why is it important to take land after mining?

Mining is known to be an act that disturbs the land. A lot of mines now are been known to reclaim the face in the course and after mining is completed, and therefore they return the land for useful purposes.

Reclaimed mine lands are known to be veritably beautiful and useful to wildlife and mortal uses.
