Organism: Apple
All cells from the apple come from cell division occurring from the apple in order for it to grow.
An apple has multiple cells
The small living part in an apple is a cell thus showing that cells are the basic living unit.

best answer i could say was this
Answer:
Solubility range of KI in 500 grams of water at 20 degrees C is 700-740gm
Explanation:
Using the solubility curve of the solubility of KI with the given temperature
we infer from the graph that at 20 degrees Celsius the solubility of KI is 140-148 grams per 100 grams of water.
so for 500 grams of water the solubility of KI will be
= 140*5= 700gm to 148*5= 740
Solubility range of KI in 500 grams of water at 20 degrees C is 700-740gm
A hypothesis is an assumption made before an experiment while a theory is made after collecting a lot of scientific evidence.
Answer:
3.2 × 10³ J
Explanation:
Step 1: Given data
- Mass of the gold ring (m): 25 g
- Specific heat capacity of gold (Cp): 0.129 J/g.°C
- Initial temperature: 75 °C
- Final temperature: 1064 °C
Step 2: Calculate the temperature change (ΔT)
ΔT = 1064 °C - 75 °C = 989 °C
Step 3: Calculate the energy required (Q)
We will use the following expression.
Q = Cp × m × ΔT
Q = 0.129 J/g.°C × 25 g × 989 °C
Q = 3.2 × 10³ J
