There are four environments on Earth that are called spheres: hydrosphere, lithosphere, atmosphere, and biosphere.
<h3>Features associated with each of Earth's four spheres.</h3>
<h3>Hydrosphere </h3>
It is the set of all the water on the planet, including those that form clouds.
<h3>Lithosphere</h3>
 The continuous part of our planet, made up of rocks and soil. The most superficial part is called the earth's crust.
<h3>Atmosphere</h3>
It is the gaseous sphere that surrounds our planet, composed mainly of gas oxygen and gas.
<h3>Biosphere </h3>
It is the part of our planet that can support life
<h3>Internal processes</h3>
The atmosphere and hydrosphere are the main regulators of the planet's climate. Without both, the temperature changes would be very sudden: at night it would drop to minus 150°C and during the day above 100°C, making life on Earth difficult.
With this information, we can conclude that the spheres of the earth, support life, and make the planet earth unique.

Answer:
Transgenic animals require a host to grow but transgenic bacteria and plants do not require host.
Explanation:
Transgenic organisms are the organisms in which foreign genetic material are introduced so that the transgenic organism can get some particular traits and characteristic.
The process of producing transgenic animals is different from producing transgenic plant and transgenic animals because in transgenic animals DNA from a cell is transferred into an enucleated oocyte.  
Then this oocyte is transferred to the oviduct of a surrogate mother to raise the genetically modifies embryo but in plant and microbe, no host is required.
 
        
             
        
        
        
2 benefits would be that diseases that run in the family which could be genetically passed down could be erased, the other benefit is that people well or babies could be modified to the parent’s liking
        
             
        
        
        
The sun creates it's own light, also gives light and life to bunch of stuff like plants,animals,humans etc.photosyntesis is the process of making food which needs sun,water,nutrients etc.
        
                    
             
        
        
        
To test the saying, Megan has to use steps of scientific method.
The first thing that the Megan should do is to make a hypothesis that ''bees makes a fine honey from berry orchid.'' Then he has to do experiment by placing the apiaries in the berry orchids in order to find out his hypothesis. After sometime, Megan has to collect the data and draw the conclusion in the light of her observation in order to find out that the honey bees made honey or not so in this way the Megan used steps of scientific method in order to test their hypothesis.
