Answer:
1) Every planet's orbit is an ellipse with the sun at a focus. 
2) A line joining the sun and a planet sweeps out equal areas in equal time(s)
3) The square of a planet's orbital period is proportional to the cube of semi major axis of it's orbit
 
        
             
        
        
        
point, shift deletion, UV rays, radiations, genetics mutations, gene editing
That is just some method that gene can change within the DNA
 
        
             
        
        
        
<span>1.      
</span>Cones perceive
light in color while rods perceive light in black and white.
<span>2.      
</span>Rods can perceive dim light, unlike cones. The rods are located at the edges of the eyes. This is why it easier to perceive an image in the dark through
the corner of the eyes.
<span>3.      
</span>The discs that compose the cones are usually
partially open to the surrounding vitreous
fluid while those of the rods are closed. 
 
        
             
        
        
        
<h2>Answer and Explanation </h2>
When two daughter cell has the same number of chromosomes in the DNA is called Mitosis. The mitosis is the name of the process by which cell membrane divides to form two new daughter cells by dividing the cytoplasm of the cell both daughter cells have their own cell wall and nuclei after division. The process in which the cytoplasm divide is called cytokinesis. Mitosis is a process in which chromosomes are segregated to form a daughter nuclei.
 
        
             
        
        
        
The answer is D because <span>In </span>exocytosis<span>, materials are </span>exported<span> out of the cell via secretory vesicles. In this process, the Golgi complex packages macromolecules into transport vesicles that travel to and fuse with the plasma membrane. This fusion causes the vesicle to spill its contents out of the cell. Exocytosis is important in expulsion of waste materials out of the cell and in the secretion of cellular products such as digestive enzymes or hormones.</span>
