The answer is copper. Nonrenewable resources are those that cannot be readily/naturally replaced at rates that match those of consumption (an aspect that allow renewable resources to be sustainable). Copper are made deep in earth at very slow rates hence do not readily renew themselves. Organisms, on the other hand die, and are naturally replaced by offspring.
Answer:
a. Ligase
b. Ligase (
it's repeated)
Explanation:
DNA synthesis begins, therefore, by synthesizing a short segment of RNA called a primer, which primer is synthesized by an enzyme called Primasa. Primasa is an RNA polymerase that uses DNA as a template. All fragments of Okazaki begin with a Primer. Subsequently, the DNA polymerase III Holoenzyme performs the synthesis of the corresponding DNA fragment until it reaches the next primer. At that time, DNA polymerase Ia replaces the DNA polymerase Holoenzyme III. The DNA polymerase I is responsible for removing the RNA primer through its 5'P-3'OH exonueotic activity and at the same time fills the hole by synthesizing DNA.
Finally, the two Okazaki fragments have to be joined, it is necessary to link the 3'OH end of a fragment with the 5'P of the next fragment. This work of sealing and joining the successive fragments is done by Ligase.
<h2>Anatomy of Aorta</h2>
Explanation:
- The protein elastin is found in connective tissues all through the body. It is eminently found in the extracellular lattice of the skin just as the inward organs of the body. The name elastin sounds a lot of like 'flexible.' This is no fortuitous event. The elastin protein is adaptable and gives numerous tissues their versatility.
- Inferable from its exceptional capacity to extend and withdraw, the aorta additionally fills in as a store that changes the profoundly compelled and pulsatile heart yield into a progression of moderate variances.
- The tunica intima comprises of a solitary layer of ECs that lines the lumen of the vein and is moored to the fundamental cellar film, an exceptionally particular ECM organize comprising basically of laminin, collagen type IV, fibronectin, perlecan, and heparan sulfate proteoglycans.
- This storm cellar layer additionally assumes a vital job in flagging occasions that direct EC movement, intrusion, expansion, and survival. The cellar film together with the inward flexible lamina (IEL) fills in as an interface between the tunica intima and tunica media.
Nitrogen is returned to the atmosphere during the nitrogen cycle in a process referred to as denitrification.
<h3>What is denitrification?</h3>
It is a process whereby nitrogen becomes mineralized from nitrogenous compounds. In other words, it is the reduction of nitrates to produce elemental nitrogen which is returned to the atmosphere.
Denitrification is a microorganisms-driven process. The nitrates are made to pass through a series of reactions with intermediate products before finally leading to the production of elemental nitrogen.
