<span>The question says,'the orange colour of carrot roots and marigold flowers comes from cell bodies known as chromoplasts. The statement is true. Chromoplasts are coloured plastids, they usually contain a yellow or orange pigment. They can be found in roots, leaves, fruits and ageing leaves and are responsible for the distinctive colours of these plant parts.</span>
Gregor Mendel planted garden peas and used them as the basis of his study of inherited traits. They do not mature slowly.
Answer:
Solid 1 has the smallest amount of plasma membrane per volume of cytoplasm
<em>Note: The question is incomplete. The attachment below gives the complete question</em>
Explanation:
The outermost surface of a cell is bounded by the plasma membrane which functions to maintain the integrity of the cell as well as control the movement of particles in and out of the cell.
The ratio of the surface area of a cell to the volume of the cell indicates how big the cell is. When the surface area to volume ratio is small, the cell is very big, but if the surface area to volume ratio is big, the cell is small.
From the attachment below, the surface area (plasma membrane) per volume of plasma of the rectangular solids are as follows:
Solid 1: 10/2 = 5 cm⁻¹
Solid 2: 12.18/2 = 6.09 cm⁻¹
Solid 3: 19.0/2 = 9.5 cm⁻¹
Solid 4: 34.24/2 = 17.12 cm⁻¹
Solid 5: 65.79/2 = 32.895 cm⁻¹
Solid 1 has the smallest amount of plasma membrane per volume of cytoplasm
I believe it’s | Weathering |
How you know:
The damage was done by temperature, which has to do with weather.
Erosion is usually caused overtime by water elements , and it causes the rocks to erode.
Answer: weathering
