Using subject academic vocabulary (ex. Pretend you are teaching a friend about the differences between plant and animals cells.

Your friend isn’t even sure they know there is a difference between the types of cells.) write a narrative of what you would say to your friend to explain how the plant and animal cells are different from each other and why these differences are important.

The difference between the plant and animal cells is in their structures, and this makes their functions to differ. Some organelles are present in the plant cell which are absent in the animal cell and vice versa. The presence/absence of these organelles impact the kind of functions that can be carried out by each cell.

  • The plant cell has a rigid cell wall made of polysaccharides while the animal cell lacks cell wall. The cell wall serves supportive functions in the plant and gives it a shape. Animal cells are more or less round in shape.
  • Plant cells have chloroplasts while it is absent in the animal cell. the chloroplast contains chlorophyll, a green pigment that is responsible to absorbing radiant energy, As such, the chloroplast enables plant cells to carry out photosynthesis. Animals cells cannot synthesize their own foods.
  • Plant cells have large central vacuole that stores water and other contents while animal cells have small vacuole
  • Animal cells have centrioles while plant cells do not. The centrioles make mitotic division different between the two cells, although, the same result is obtained at the end of the day.

You notice that the water in your friend's swimming pool is cloudy and that the pool walls are discolored at the water line. A q
kicyunya [14]

Answer:

3,78 mL of 12,0wt% H₂SO₄

Explanation:

The equilibrium in water is:

H₂O (l) ⇄ H⁺ (aq) + OH⁻ (aq)

The initial concentration of [H⁺] is 10⁻⁸ M and final desired concentration is [H⁺] = 10^{-7,2}

Thus, you need to add:

[H⁺] = 10^{-7,2} - 10^{-8} = <em>5,31x10⁻⁸ M</em>

The total volume of the pool is:

7,00 m × 18,0 m ×1,50 m = 189 m³ ≡ 189000 L

Thus, moles of H⁺ you need to add are:

5,31x10⁻⁸ M × 189000 L = 1,00<em>x10⁻² moles of H⁺</em>

These moles comes from

H₂SO₄ → 2H⁺ +SO₄²⁻

Thus:

1,00x10⁻² moles of H⁺ × \frac{1 H_{2}SO_{4} moles}{2H^+ mole} = <em>5,00x10⁻³ moles of H₂SO₄</em>

These moles comes from:

5,00x10⁻³ moles of H₂SO₄ × \frac{98,1g}{1mol} × \frac{100 gsolution}{12 g H_{2}SO_{4} } × \frac{1mL}{1,080 g} = <em>3,78 mL of 12,0wt% H₂SO₄</em>

<em></em>

I hope it helps!

Algae are microscopic plants that grow in the ocean. Algae must have sunlight, nutrients, and water to survive. They conditions
Papessa [141]

The condition is called phytoplankton because algae are microscopic, need sunlight and nutrient, water to survive.

<h3>What is phytoplankton?</h3>

Phytoplankton refers to microscopic marine algae and they are also called microalgae.They are similar to terrestrial plants in that they contain chlorophyll and require sunlight in order to live and grow. Most phytoplankton are very buoyant and float in the upper part of the ocean, where sunlight enter the water and they get the sunlight to produce food.

Algae photosynthesized,that is they use sunlight in the presence of chlorophyii and carbondioxide to produce food and oxygen.

Therefore, The condition is called phytoplankton because algae are microscopic, need sunlight and nutrient, water to survive.
