A small flowerless green plant with leaflike stems or lobed leaves, occurring in moist habitats. Liverworts lack true roots and reproduce by means of spores released from capsules.
Both the extremities, flagella and cilia, are alike in that they help the cell in this mobilization. Thus, the answer to this item is letter "C. they assist with movement". With their appearances, both are hair - like structures but flagella are longer compared to the cilia.
Answer:
![3.47](https://tex.z-dn.net/?f=3.47)
Explanation:
Mechanical advantage is given by the ratio of output force by input force.
= Output force = ![1549\ \text{N}](https://tex.z-dn.net/?f=1549%5C%20%5Ctext%7BN%7D)
= Input force = ![446\ \text{N}](https://tex.z-dn.net/?f=446%5C%20%5Ctext%7BN%7D)
So,
![MA=\dfrac{F_o}{F_i}\\\Rightarrow MA=\dfrac{1549}{446}\\\Rightarrow MA=3.47](https://tex.z-dn.net/?f=MA%3D%5Cdfrac%7BF_o%7D%7BF_i%7D%5C%5C%5CRightarrow%20MA%3D%5Cdfrac%7B1549%7D%7B446%7D%5C%5C%5CRightarrow%20MA%3D3.47)
