Question:
In order for your mutant dragon population to become its own species, and needs to be separated from the original dragon population so they no longer will mate with each other. come up with an idea of how the mutant dragon population can separate itself from the original population. Link it to your environmental change.
Answer:
There are various tactics that can be used to separate the mutant dragon population, in order to create a new speices. One tactic is to lure the dragons to a location that provides them with a better food supply. Another tactic could be to temporarily relocate the whelps or fledglings, and leaving behind a trail for the Family to follow. The goal is separate the mutant dragon population from the other, and the propositions that I have provided above could possibly be the solution.

Which system prepares the body for the situation
described in the scenario?
the somatic nervous system
the parasympathetic nervous system
the central nervous system
the sympathetic nervous system
Answer:
D) The Sympathetic Nervous System
Explanation:
The brain and spinal cord make up the central nervous system. The peripheral nervous system is comprised of the somatic and autonomic nervous systems. The somatic nervous system transmits sensory and motor signals to and from the central nervous system. The autonomic nervous system controls the function of our organs and glands, and can be divided into the sympathetic and parasympathetic divisions. Sympathetic activation prepares us for fight or flight, while parasympathetic activation is associated with normal functioning under relaxed conditions.
Answer:
Its D the sympathetic nervous system

Identify the types of breezes and the areas of high and low pressure that cause them.
Answer:
Explanation:
Breeze are formed from difference in air temperature .
We have the land breeze and sea breeze,
The sea breeze blows from the inward part of the ocean to the land. It takes place during the day, when sun heats up the land it increase the temperature in the ground causing land to heat up resulting in warm air and low pressure but it takes a longer time for ocean body to heat up hence the pressure in the ocean is usually higher, this result in sea breeze.
Land breeze is the breeze that blows from the land to the ocean. At night, land looses the heat cause by increase temperature and becomes cooler but because it takes a longer time for ocean body to get warm heats accumulated are not easily given up hence the pressure on ocean is usually low at night while the pressure of land is higher the difference beings about air breeze from land to the sea.

Two next-door neighbours use very different strategies when it comes to landscaping their front yards. One neighbour plants a front lawn of lush green grass that requires regular watering and fertilizer application. The other neighbour uses
stone pathways that wind through a variety of drought-resistant wild flowers and shrubs that are native to the area.
Explain why the drought-resistant wild flowers and native shrubs contribute more to the sustainability of a yard than does the lush green grass.
Answer: When the city/county/state/region declares a drought and stops the use of water on lawns, the green stuff dies.The guy with the drought resistant set up will hardly notice any difference in the look of his yard.
Explanation:
It is observed In the case of grass lawns, that the lush green grasses have more requirements as compared to the area covered with wildflowers and shrubs.
What are their requirements?The requirements include one of the most essential elements water. Compared to the drought-resistant plants grown by the second neighbor, the grass lawns require a large amount of water for their growth. This in turn adds a burden in the form of water requirements.
How do they survive?Drought-resistant plants take nutrients in the form of nourishment and protection whereas the grass requires the use of fertilizers as well as chemical pesticides to provide resistance to the grass against the potent pests and due to the requirement of a large amount of water by the lawns, there are chances of these chemicals getting washed away and entering into a nearby water source, and they don't get enough of the nourishment.
The drought-resistant varieties and the native plants are more potent to survive the conditions already present there and thus are more sustainable.

Which of these is the most practical method to prevent global water shortage? A. Stop planting trees and shrubs in gardens. B. Conserve, recycle, and reuse water in households. C. Stop using appliances like washing machines and dishwashers. D. Discourage setting up of power plants which need cooling water.
Answer:
B. Conserve, recycle, and reuse water in households
Explanation:
I think B will be the best way to prevent global shortage because...
A. If we stop planting trees and shrubs in gardens that will reduce water shortage just by a little and trees are very important for fresh air and are equally important as water so its not a nice way to prevent global water shortage.
C. It will be very hard for people who use washing machines and dishwashers to stop using them because they are not used to clean their clothes/dishes by themselves and would be a very hard task to stop using it.

Question 7: What might be some implications of Robert Hazen’s experiments
and research? Cite evidence from the text to support your answer.
Answer:
Robert Hazen’s studied enviromental and biological processes that might have been critical for life, and also for the formation of approximately two-thirds of Earth's mineral species (see Hazen et al., 2008; Gonzalez & Richards 2020) .
Explanation:
Hazen provided evidence about how first organic molecules were generated on the primitive earth millions of years ago. He observed that high-pressure hydrothermal vents may provide food for underwater ecosystems. It represents a piece of critical evidence on the origin of life.
You can read these articles that are certainly clarifying in the description of his experiments and discoveries:

Summarize the reasons why systematists separated Domain Bacteria from Domain Archaea.
Answer:
Initially, Archaea were classified as part of Bacteria, but sequencing technologies enabled them to separate these phylogenetic groups.
Explanation:
Archaea and Bacteria are different domains that belong to a kingdom known as prokaryotes. Prokaryotes are unicellular organisms that lack membrane nucleus, and any class of internal membrane, thereby they neither have organelles. These domains (Archaea and Bacteria) are primarily classified according to the level of sequence homology, being archaea organisms closer to eukaryotes compared than bacteria. Moreover, it has also been proposed that Bacteria are ancestors of eukaryotic organelles.
Due to the certain differences in their morphology and habitats, the Archea are the separate domain from domain Bacteria of life in prokaryotes.
ArchaeaIt is considered as the different domain of life in prokaryotes. These are the most primitive type and are known as the ancient microorganisms found in extreme niches.
They also have morphological differences as well as biochemical than bacteria which are rarely to be seen in those harsh conditions on which archaea can thrive. Their reliance on ether lipids in their cell membranes. Bacteria have phospholipid membranes.
