Answer:

The microorganisms present metabolic wastes that serve as the primary source of food for other living things.

Bacteria that live free in the soil or in symbiosis with plants are essential to fix nitrogen, both nitrates and ammonia. These bacteria take nitrogen directly from the air, originating compounds that can be incorporated into the composition of the soil or living beings.

This property is restricted only to prokaryotes and is widely distributed among different groups of bacteria and some archaeobacteria. It is a process that consumes a lot of energy that occurs with the mediation of the enzyme nitrogenase, which the rest of the living organisms that cannot do or comply with this process is because they lack said enzyme.

Dunaliella is a genus of microscopic algae of the Chlorophyceae class and of the order Volvocales. All are unicellular, although with very varied morphologies.

Morphologically, its main characteristic is that they lack a rigid polysaccharide cell wall.

The ecology of this genus of green algae is characterized by its high tolerance to salinity, with eukaryotic organisms having greater tolerance to salt. They are euryhaline, adapted to salt concentrations from 50 mM NaCl to almost 5.5 M NaCl.

Explanation:

By nitrogen fixation is meant the combination of molecular nitrogen or dinitrogen with oxygen or hydrogen to give oxides or ammonia that can be incorporated into the biosphere. Molecular nitrogen, which is the majority component of the atmosphere, is inert and not directly usable by most living things. Nitrogen fixation can occur abiotic (without the intervention of living beings) or by the action of microorganisms (biological nitrogen fixation). Fixation in general involves the incorporation into the biosphere of a significant amount of nitrogen, which globally can reach about 250 million tons per year, of which 150 correspond to biological fixation.

A bond of the following elements would be of what type? Ca + 2Cl Covalent or ionic

dedylja [7]

Answer:

Ionic

Explanation:

Ionic bond:

It is the bond which is formed by the transfer of electron from one atom to the atom of another element.

Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.

For example:

calcium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for calcium is 1. There is large difference is present. That's why electron from calcium is transfer to the chlorine. calcium becomes positive and chlorine becomes negative ion.

There are two valance electrons in calcium so it needed to lose two valance electrons to complete the octet while chlorine needed one electron to complete the octet. Thus two electrons lost by one calcium atom are gained by two atoms of chlorine.

Ca + Cl₂ → CaCl₂

Nitrogen is a nutrient that organisms need to produce (12) . Plants and animals cannot use the nitrogen that makes up a large pe

Dmitriy789 [7]

Answer:

12. Protein 13. Atmosphere 14. Nitrogen fixation 15. Plants 16. Consumers 17. Urinate 18. Decay 19. Decomposers 20. Ammonia 21. Denitrification

Explanation:

12. Protein

Nitrogen is essential to organisms. It is the main constituent of amino acids, which is the building blocks of protein in organisms.

13. Atmosphere

Nitrogen occurs naturally as gas in the earth’s atmosphere, accounts for about 78% of gases found in the atmosphere. This gaseous Nitrogen which is inert cannot be accessed by plants and animals for use.

14. Nitrogen fixation

For plants to be able to use the gaseous Nitrogen in the atmosphere, Nitrogen fixation has to take place. It involves the turning of gaseous Nitrogen in the atmosphere into ammonia. Nitrogen atoms is combined with Hydrogen atoms by enzyme called “nitrogenase”. This enzyme is present in nitrogen-fixing bacteria.

15. Plants

Nitrogen enters the food web when plants assimilate nitrogen compounds from the soil to form nucleotides, amino acids, and other important chemicals in life.

16. Consumers

Consumers are mainly animals that feed on plants in an ecological food web in other to be able to use the amino and nucleic acids formed from Nitrogen as a major component. Consumers can be categorized as primary, secondary, and tertiary consumers.

17. Urinate

Nitrogen is very much concentrated in the urine of animals and also in their faeces. As animals urinate, Nitrogen is being returned to the soil.

18. Decay

Decay starts, as organisms die. The organisms start decomposing.

19. Decomposers

Decomposers are the bacteria in the soil that break down the nucleic and amino acids in dead organisms into nitrates and ammonia through a process called ammonification

20. Ammonia

This is the end result of the decomposition of dead organisms by decomposers

21. Denitrification

Compounds of nitrogen are turned back into gaseous nitrogen by anaerobic bacteria. This prevents

What is sustainability?

oksano4ka [1.4K]

Answer:

A set of practices that humans can follow to meet their needs without causing long-term, negative effects on species or ecosystems.

Explanation:

Sustainability means "the ability to be maintained at a certain rate or level." So sustainability is the ability for humans to meet their needs, while also maintaining the ecosystem and different species at the same rate and level.

Telomerase activity may decline with old age and this could explain why cells lose their ability to divide after many replicatio

Bumek [7]

It is true that telomerase activity declines with old age which explains why cells lose their ability to divide after many replications.

Telomeres are DNA–protein complexes found at the ends of each chromosome they contain repetitive sequences of DNA. Telomeres protect the genome from nucleic bases degradation, unnecessary recombination, repair, and prevent the fusion of chromosomes. Telomeres, therefore, play a vital role in preserving the information in our genome.

Telomeres shorten with every consecutive DNA replication cycle limiting the number of cell divisions a cell can undergo, Telomeres act as a tumor suppressor by halting the replication of cells which contains several mutations after many division cycles.
