Answer:
<u><em>I HOPE IT WILL BE YOUR ANSWER:</em></u>
Explanation:
As given
60 min = 50 gm (1)
then we know half-life mean half amount decay time
so we can write as the half of 200 is 100 gm hence
T 1/2 = 100 (2)
solving these two equation by cross multiplication we will get
T 1/2 = 120 min

<h2>Answer:</h2>
The correct answer is option C which is cell can be a plant cell or an animal cell.
Explanation:
- The statement is is that cell has cell membrane. Cell membrane is the outer covering membrane which is present in both cells. While cell wall is a external hard membrane present only in plant cells.
- In the statement D, the presence in the large molecule usually in the center of cell is the indication of plant cell. It gives the upright direction in plants and it stores large amount of water and food.
- Hence the correct answer is option C.
<span>Among the choices provided, the answer is letter C, CuSO4(aq) + Fe(s) → FeSO4(aq) + Cu(s) since Iron(Fe) is higher up on the action graph and is, along these lines, more responsive than Copper(Cu). Because of this, Iron can supplant Copper in that substance equation. </span>
Continental shelf
is the edge of a continent that lies under the ocean. It extends from the coastline of a continent to a drop-off point called the shelf break. Even though they are underwater, continental shelves are part of the continent. The formation of continental shelves were once dry land, the most recent ice age, much of the frozen huge masses of ice glaciers.
