The identity of an atom can be determined by the number of protons it has. A is the correct answer. I hope this helps!
Answer:
2 Valencia shells (K and L)
Explanation:
Carbon has 6 protons and its configuration using KLMN shell is
2, 1. Which is under K and L.
Answer:
The hawk population will drop while the rabbit population will rise.
Explanation:
With the way the pyramid is structured, it shows that the rabbits eat grass, snakes eat the rabbits, and hawks eat the snakes. If the snakes are gone, the hawks will lose a food source, and their population will drop. Also, the rabbit population will rise, because the snakes eat the rabbits, and if the snakes are gone, they won't have any predators.
Answer: Hydrosphere is the total mass of water found on the Earth's surface. Atmosphere is the layer of air that envelopes the Earth. Hydrosphere consists of lakes, oceans, rivers, seas, water vapours, underground water and ice sheets of the mountainous regions.
Explanation:
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.
