Tcecarenko [31]

The result for TEST FOR LIFE is that the sample produces ATP. The sample is plant.
D Is going to be your answer

Explanation:
The chloroplasts are cell structures that are photosynthesis. The Golgi apparatus is the site transport of substance out of the cell. Mitochondria is the site of cellular respiration.
The two main functions of organelle is that it stores the herediatary material, DNA and it coordinates the cell's activities like growth, intermediary metabolism, protein synthesis, and reproduction. Eukaryotes are the cells of advanced organisms have a nucleus.
The results of the sample produces ATP, the sample is plant and the plant cells have an envelope surrounding the nucleus.

Hope this helps.!!! And please mark brainliest thank you!!

Which color of light has the greatest energy
ozzi

Answer:

violet

Explanation:

Waves with a short wavelength have the most energy. Red waves have a relatively long wavelength (in the 700 nm range), and violet waves are much shorter - roughly half that. Because violet waves have the shortest wavelength of the visible light spectrum, they carry the most energy (google)

What mass of butane in grams is necessary to produce 1.5×103 kJ1.5×103 kJ of heat? What mass of CO2CO2 is produced? Assume the r
saul85 [17]

32.8 g of Butane is required and 99.3 g of CO₂ is produced

<u>Explanation:</u>

The above mentioned reaction can be written as,

C₄H₁₀(g) + 13 O₂(g) → 4CO₂(g) + 5 H₂O(g)     where ΔH (rxn)= -2658 kJ

It is given that 1.5 × 10³ kJ of energy is produced, the original reaction says that 2658 kJ of heat is produced, which means that less than one mole of butane is used in the reaction.

That is

$\frac{1500}{2658}=0.564 \text { moles }    of butane reacted

Now this moles is converted into mass by multiplying it with its molar mass  = 0.564 mol × 58.122 g / mol

                     = 32.8 g of butane.

Mass of CO₂ produced = 0.564 ×44.01 g /mol × 4 mol

                                        = 99.3 g of CO₂

Thus 32.8 g of Butane is required and 99.3 g of CO₂ is produced
