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.
Note:
This is the best I could do with the limited information that was given. I advise that you only resort to this if truly needed. I don't have much experience or knowledge in this Topic. I just thought I might give it a try. I hope you get a better answer soon!

On April 20, 2010, an explosion on the Deepwater Horizon Macondo oil well drilling platform released 4 million barrels (636,000 cubic meters) of oil into the Gulf of Mexico. It took scientists and engineers nearly three months and several different attempts to cap the well. The Macondo oil well was located 1524 m (5000 feet) below the surface of the water, about 80 km (50 miles) off the coast of Louisiana. The spill affected 2113 km (1300 miles) of shoreline along the coasts of five states. Most crude oil contains 84–87% carbon by weight. Scientists have not yet fully assessed the environmental impact of the accident.
Computer modeling can be used to help improve cleanup and response systems for the next major oil spill. Which of these uses demonstrates how computer modeling can be used to minimize the impact of another spill?
a
Creating a model of how the oil spread through the Gulf of Mexico to predict what areas need the greatest amount of protection.
b
Calculating the total oil that entered the Gulf of Mexico during the spill.
c
Recording the number and type of each dead organism collected during the spill.
d
Finding the average flow rate of the oil through the burst pipeline during the spill.
Answer:
I would pick a, because if you can see where the most oil spills or where it flows it will be easier to predict when another spill is about to happen.

Which describes a target cell? releases hormones into the blood produces a particular hormone recognizes a hormone’s chemical structure destroys hormones in the blood
Answer:
recognizes a hormone’s chemical structure
Explanation:
In living systems, chemical messengers called hormones are secreted into the body via the bloodstream or ducts by certain glands called endocrine glands e.g pancreas, hypothalamus etc. These hormones are meant to effect a physiological change in certain cells called TARGET CELLS.
In biology, a target cell is any receiving cell that has the ability to respond to signals and messengers like hormones. This responding ability of hormones is due to the possession of specific receptor sites for the specific hormones. The receptor on a particular target cell recognizes that specific hormone's chemical structure, hence, will only respond to it.
For example, an insulin hormone secreted by the pancreas will only be responded to by a target cell that recognizes the chemical structure of the insulin protein using its receptor molecule.
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.

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.

Why is flooding more likely after many trees are removed from an area?
A. Without the trees, evaporation rates slow down.
B. Without the trees, water runs off rather than percolating into the
soil.
C. Without the trees, most of the animals die and therefore don't
drink the water.
D. Without the trees, precipitation increases dramatically.
SUBMIT
Answer:
Without the trees, water runs off rather than percolating into the
soil.
Explanation:
Flooding is the excessive flow of water due to increased rainfall. It usually deprives the soil of the affected area of essential nutrients. However, the presence of trees in an area can help prevent or reduce the possibility of flooding. The roots of large trees help hold the soil together, which improves the porousness of the soil. Also, trees store water that is meant to runoff.
Without the trees, the absorption or percolation of water into the ground/soil will be reduced, hence, the excess water runsoff the surface leading to flooding.

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.
