Answer:
irregular
Explanation:
Irregular galaxies have no regular or symmetrical structure. They are divided into two groups, Irr I and IrrII. Irr I type galaxies have HII regions, which are regions of elemental hydrogen gas, and many Population I stars, which are young hot stars.
The order is observation, question, propose a hypothesis, make a prediction, test, results, changing outlets worked, propose a new hypothesis and make a new prediction.
<h3>What is the scientific method?</h3>
The scientific method can be defined as a series of sequential steps in order to collect empirical evidence and thus test hypotheses that allow making predictions related to their outcomes.
In conclusion, the order is observation, question, propose a hypothesis, make a prediction, test, results, changing outlets worked, propose a new hypothesis and make a new prediction.

1. A) carnivore; third
The trophic levels are divided by the manner in which the energy is produced and consumed among the living organisms. The first trophic level is occupied by the autotrophs, which are the organisms that are able to produce their own food. The second trophic level is occupied by the organisms that feed upon the autotrophs, thus they are the herbivores, as well as the omnivores in partial sense. In this case we will have the ants at the second level. The third trophic level is reserved for the organisms that feed upon the organisms of the second trophic level, thus they are predators. In this case, we will have the wasp in the third trophic level.
2. B) consumption; 20
If there are herbivores and plants, the plants account for 1,000 kg in biomass, and the herbivores eat 200 kg of them, then the consumption is 20% of the total biomass. This kind of a scenario is able to support the whole population of herbivores without any problem, as there is much more food than they need. It will only become a problem if the population of herbivores starts to grow exponentially, and they start to consume all of the food and even require more, the population will collapse.
3. C) N20
The processes and nitrification and denitrification are very common, both in nature, and because of the human activity. The human activity has actually increased this process significantly. The main product of the nitrification-denitrification is the N2O. It is a vital product for the nitrogen cycle, and it is one that is increasing the atmospheric temperature, thus too much of it is not of best interest for anyone.
A. Basins are the landforms that are most likely to have coal, oil and gas deposits. Much of the countries natural gas, oil and coal are deposited in the bottom of basins.
