Answer:

The theory of aging evolution

Explanation:

The theory of aging evolution seeks to investigate the reasons why living beings begin a degeneration process at a certain age, among the various theories proposed is that of <em>Peter Brian Medawar</em> proposed in 1952, who claimed that natural selection avoided these mutations malignant <em>during the reproductive stage</em> to avoid the reduction of the population, however once this stage concluded the selection allowed them to manifest themselves.

Given that polyurethane is a huge polymer (mw &gt;&gt;?????????,????????? daltons), why is it important that the polyurethanase
Viefleur [7K]

Polyurethanase is an enzyme emitted by the microorganism so as to break polyurethane. Since the polymer is a significant wellspring of energy for the life form, it should be separated all together for etpum"s development.

Further details

Polyurethane

It is a polymer made out of organic units and carbamate links join them. While most polyurethanes are thermosetting polymers that don't liquefy when warmed, thermoplastic polyurethanes are likewise accessible. Polyurethanes are available in numerous parts of present-day life. They present a class of polymers that have discovered a far-reaching use in the medical and mechanical fields. Polyurethanes can be found in items such as furniture, coatings, cement, constructional materials, paints, elastomers, filaments and paddings. Polyurethane ought to be curtailed to PUR in consistence with authority German and International benchmarks.

Polyurethanase

It can be defined as such an enzyme which is secreted by microbes and used for the breakdown of polyurethane. In this breakdown process energy is released that is utilized by microorganisms.

Bio-degradation of Polyurethane

In spite of their microbial obstruction, polyurethane is attacked by microscopic organisms however the component to explain its bio-degradation is unknown. There are reports from microscopic organisms and parasites that are equipped for the breakdown of polyurethane yet the examinations about the proteins that assault the plastic are centered around bacterial compounds as it were. The enzyme is of sort esterase and protease for the most part since these chemicals are unspecific and can perceive a few regions in the polyurethane particle and hydrolyze it.

Do Meiosis and Mitosis occur in all organisms?
NemiM [27]

Answer:

No, not <em>all </em>organisms.

Explanation:

Hi there,

As you may continue to learn in biology, not all organisms go through the process of mitosis/meiosis. Well known examples are prokaryotes, such as  bacteria and archaea, ancient organisms that replicate via binary fission, budding, and/or fragmenting

Mitosis and Meiosis only occur in eukaryotes and unique to them.

thanks,
