your answer in complete sentences. be original

Answers

Answer:

A paramecium is similar to a giraffe in one defining way. Both a giraffe and paramecium have eukaryotic cells. One way in which the two are different is that the paramecium feeds on decaying organisms, whilst a giraffe eats leaves. Another is that paramecium primarily live in fresh water, while a giraffe dwells on land.

A paramecium and a giraffe are two very different organisms. A paramecium is a single-celled organism, while a giraffe is a large, multicellular mammal. Despite their many differences, both a paramecium and a giraffe have cells. However, the cells of a paramecium and a giraffe are quite different from each other in terms of size, shape, and function.

One of the most significant differences between the cells of a paramecium and a giraffe is their size. The cells of a paramecium are very small, measuring only a few micrometers in diameter. In contrast, the cells of a giraffe are much larger and more varied in size, depending on their function within the body. For example, giraffe nerve cells are much larger than giraffe red blood cells.

Another important difference between the cells of a paramecium and a giraffe is their shape. The cells of a paramecium are typically elongated and oval-shaped, with a pointed end at one end and a rounded end at the other. In contrast, the cells of a giraffe are much more varied in shape, depending on their location and function within the body. For example, giraffe muscle cells are long and cylindrical, while giraffe nerve cells are elongated and have many branching extensions.

Despite their many differences, the cells of a paramecium and a giraffe do have some similarities. For example, both types of cells have a cell membrane that surrounds the cell and controls the movement of materials in and out of the cell. Both types of cells also have a cytoskeleton, which provides support and structure to the cell. Additionally, both types of cells have a nucleus, which contains the cell's genetic material.

Overall, while the cells of a paramecium and a giraffe have some similarities, they are also very different from each other in terms of size, shape, and function. The small, simple cells of a paramecium are adapted for life in a single-celled organism, while the larger, more complex cells of a giraffe are adapted for life in a multicellular mammal.

What is Osmosis, Diffusion in your own words or just a simple definition.

Answers

Osmosis is the phenomenon of the passage of solvent molecules, through a semipermeable membrane, from the solvent to the solution or from the solution of lower concentration (thinner) to the solution of higher concentration of solute (thicker).

diffusion,is characterized by the tendency of molecules of a substance to disperse from areas of higher concentration to areas of lower concentration. This tendency is manifested by a corresponding movement of the molecules. This means that the movement of molecules occurs in both directions, at a faster rate from the area of ​​higher concentration.

Osmosis - The movement of water molecules from a solution with a high concentration of to a solution with a lower concentration, through a cell's partially permeable membrane.

Diffusion - The movement of molecules from an area of high concentration of the molecules to an area with a lower concentration.

A superball with mass m equal to 50 grams is dropped from a height of hi = 1.5 m. It collides with a table, then bounces up to a height of hf = 1.0 m. The duration of the collision (the time during which the superball is in contact with the table) is tc = 15 ms. In this problem, take the positive y direction to be upward, and use g = 9.8 m/s2 for the magnitude of the acceleration due to gravity. Neglect air resistance.
