You add the following components (in the correct volumes and concentrations) to a tube to perform a PCR reaction Buffer Magnesiu
uranmaximum [27]

Answer:

b. False

Explanation:

These components are not sufficient to successfully perform a PCR reaction. Deoxynucleoside triphosphates (dATP, dGTP, dCTP, dTTP) are missing so that the PCR reaction can occur perfectly.

The PCR technique allows a specific fragment of the DNA molecule to be amplified thousands of times in just a few hours. This technique revolutionized research in molecular biology because it had taken a long time for DNA amplification. From PCR it is possible to obtain enough copies of a part of DNA to detect and analyze the sequence that is the target of the study.

For a PCR reaction to be performed a solution with some components must be prepared. These components are:

  • Magnesium chloride buffer (to optimize reaction and act as a cofactor for polymerase)
  • Forward and reverse primers (to customize the start of the enzyme reaction)
  • DNA polymerase (Enzyme required for replication of desired DNA region.)
  • DNA Template (the DNA to be copied)
  • PCR-grade water
  • Deoxynucleoside triphosphates: dATP, dGTP, dCTP, dTTP (act as bricks in the construction of DNA molecules).

How do sulfur and phosphorus move from the biotic to the abiotic pools during their cycles? A) Primary consumers eat producers.
worty [1.4K]

Answer:D) Decomposers break down the remains of producers and consumers

Explanation:A biotic pool is a tidal pool with diverse and changing habitats of living factors. We can say they are important mini ecosystems within the larger ecosystem.

The abiotic pool involves the elemental phases of nature,the non living parts of the ecosystem. Decomposition (break down) of elements/organic compounds is the characteristic bridge between both pools into what is known as nutrients.

This tell us that the ultimate dead part of producers and consumers are used up in this process.

Some of the nutrients released in the biogeochemical cyclic process includes sulfur and phosphorus and they move through the ecosystem.

Note: The biogeochemical cycle is a pathway of movement for chemical elements.

The chemical elements in nature moves through both biotic and abiotic components via abiotic and biotic interaction in the ecosystem

Few abiotic factors includes rocks, air, water, and chemicals while biotic factors includes living organisms activities.

All living and non living elements of nature play vital roles in the great biogeochemical cycle.

For both ectotherms and endotherms, metabolic rate tends to increase as mass increases

As the masses of the dinosaurs increase, how do their metabolic rates change? How does this compare to living animals?

>> As with living animals, the higher a dinosaur’s mass, the higher its metabolic rate.
