Answer:
By definition, tissues are absent from unicellular organisms. Even among the simplest multicellular species, such as sponges, tissues are lacking or are poorly differentiated. But multicellular animals and plants that are more advanced have specialized tissues that can organize and regulate an organism’s response to its environment.
High density Nebula, And condenses into a huge globule of gas and dust and contracts under its own gravity
Answer:
It would have to be nebula
Explanation:
Answer:
a) 25 J
Explanation:
Formula for kinetic energy= 1/2(mv^2)
where m(mass) =0.5kg
v(velocity) =10m/s
Therefore, Kinetic energy= 1/2(0.5*10*10)
KE =1/2(50)
KE =25 J
