meiosis dvides cells twice while mitosis dvides once. also mitosis reproduce only body cells, but meiosis reproduce sex cells
mitosis: parent cell-> duplicate-> dvide
meosis: parent cell-> duplicate-> dvide-> dvide
The term apomorphy means a specialized or derived character state; plesiomorphy refers to a primitive or ancestral trait. An same as autapomorphy is a derived trait that is unique to one group, while a same as synapomorphy is a derived trait shared by two or more groups.
Running up a tree after running straight is a change in direction thus, although the speed is same 30mph, the velocity is different. Now, in choice B, the cat is slowing down after having escaped from the dog. This is also a change in velocity (because the speed decreases).When the cat is sitting still the whole time, its velocity is 0.0mph the entire time. That means the velocity doesn't change <span>And when the cat is running around the house, the cat is changing direction (thus velocity is different).
(This is relevantly a circular motion, and acceleration is a non-zero constant, and thus veloicty of course isn't same).</span>
That’d be B. Flagella.
flagella are hair-like appendages used for moving around, and are attached directly into the outer membrane of the cell.
The answer is A (the sun)
