Answer:
4 1/4
Explanation:
17/4 = 4/4 + 4/4 + 4/4 + 4/4 + 1/4
4 + 4 = 8
4 + 4 = 8
8+8=16 = 16/4
16/4 + the 1/4 remaining in the equation = 17/4
so 4/4 + 4/4 + 4/4 + 4/4 = 4
4 + 1/4 = 4 1/4
sorry if you couldnt follow along. I am not good at explaining things but the answer is 4 1/4

<span>Cell membrane needs to allow and exit the materials that enter the cell because the cell needs nutrients and these nutrients are converted into molecules that aid in many cellular activities like repair, divide and form structures and biomolecules.
Also to excrete wastes and other harmful materials for the cell.
This continues because the cell wants to attain homeostasis.
Homeostasis is the state where the internal and external part of the body maintains and establishes balance and equilibrium. This is achieved through cellular processes in the body, the integumentary system regulates the body temperature, the hypothalamus –hunger and thirst of the individual and other interrelated organ systems that make the body healthy and in the state of equilibrium. Now, when diseases or disorders appear they disrupt the organ systems in the body thus, causing imbalance state –high fever, inability to focus and etc.<span>

Explanation:
To swim, they move their tails up and down, rather than back and forth as fishes do. This is because whales evolved from walking land mammals whose backbones did not naturally bend side to side, but up and down. ... Whales do the same thing as they swim, showing their ancient terrestrial heritage.
Cetaceans are fully aquatic marine mammals belonging to the order Artiodactyla, and branched off from other artiodactyls around 50 mya (million years ago). Cetaceans are thought to have evolved during the Eocene or earlier, sharing a closest common ancestor with hippopotamuses.
