Laurentia<span> (</span>North American Craton<span>) is a large continental </span>craton<span> that forms the ancient geological core of the </span>North American<span> continent. Many times in its past, Laurentia has been a separate </span>continent<span> as it is now in the form of North America, although originally it also included the cratonic areas of </span>Greenland<span> and also the northwestern part of </span>Scotland, known as theHebridean Terrane<span>. During other times in its past, Laurentia has been part of larger continents and </span>supercontinents<span> and itself consists of many smaller </span>terranes<span> assembled on a network of Early </span>Proterozoic orogenic<span> belts. Small </span>microcontinents<span> and oceanic islands collided with and sutured onto the ever-growing Laurentia, and together formed the stable </span>Precambriancraton seen today.
النّباتات كائنات حيّة تنتشر في جميع أنحاء العالم، وهي تعيش على اليابسة أو في المسطحات المائيّة، وتضم مملكة النّباتات أكثر من 350,000 نوع من الأشجار، والشّجيرات، والأعشاب، والسّراخس.[١] تنتج النّباتات غذاءها بنفسها عن طريق عملية البناء الضّوئي، وهي عملية تحدث داخل البلاستيدات الخضراء التي تحتوي على مادة الكلوروفيل التي تحوّل الطّاقة الشّمسيّة وغاز ثاني أكسيد الكربون إلى غذاء.7
The two major types of aquatic biomes is Freshwater and Marine. The major factor that differentiates between the two aquatic biomes is difference in Habitat.
The two major types of aquatic biomes is Freshwater and Marine.
Freshwater regions include rivers and lakes with comparatively low salt concentration.
Marine regions include Ocean, and Estuaries with comparatively high salt concentration.
The Habitat of the Freshwater and Marine life is the major differentiating factor between them.
The survival of fish is also dependent on the type of Freshwater and Marine environment.
Like, the marine water fishes can survive in a water concentration with high salt concentration.
The working of the organs of the aquatic organisms in Freshwater and Marine determines the concept of osmosis and various life important activities needed for the existence.
Fish in salt water need to maintain stable drinking conditions to maintain healthy life.
Freshwater organism finds easier to get adapted to the water environment. They are less sensitive as compared to marine water.

Answer:
Polygenic trait
Explanation:
A polygenic trait is a type of trait whose phenotype observed is affected by more than one genes i.e expression of the trait is controlled by not only a single gene but many. These traits include height or skin color and they display that display a continuous distribution; the hair color is controlled by 7 genes as described which is more than more.
Disagree
It may be a lot in quantity but it’s all the same crop
