Answer:
the answer is b.The model should show the original stem cell dividing to become a differentiated cell and another stem cell.
Explanation:
Answer:
Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells. It is like a solar panel that changes sunlight energy into electric energy. The entire process is called photosynthesis and it all depends on the little green chlorophyll molecules in each chloroplast.
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

Explanation:
The thyroid gland uses iodine from food to make two thyroid hormones that regulate the way the body uses energy. The parathyroid glands are four tiny glands located behind the thyroid gland. The parathyroid glands produce a substance (parathyroid hormone) that helps control the amount of calcium in the blood.
The two main processes by which plant cells absorb, release, and use
energy are photosynthesis and respiration. The
process of photosynthesis is present in the chloroplasts of a pant cell.
Photosynthesis uses the sun’s rays in the form of electromagnetic energy to
convert it into chemical energy to be used for the plants. It needs proteins
that are present in the plants to perform a series of necessary conversions.
Moreover, the energy from the sun is the main catalyst to convert the
carbohydrates in the plant into simpler sugars. And then a series of complex
reaction takes place that their end product is oxygen. The oxygen produced is
the cellular respiration.
