Answer : At 120°C

Explanation : At 120°C temperature the boiling point of this substance is observed in the given graph.

As per the definition of the boiling point, <em>"It is the temperature at which the vapour pressure of the given substance becomes equal to the standard surrounding atmospheric pressure"</em>

Which of these things would you expect to have cells with both mitochondria
Allushta [10]

Answer:

D. Grass​

Explanation:

Every living organism must contain one or more cells to be considered "living". Each cell, however, contains certain structures that perform specific roles called ORGANELLES. These organelles are of different types and hence, perform different tasks. For example, mitochondria is the power house of a cell i.e. site of energy production, and hence, is found in every eukaryotic cell.

On the other hand, chloroplast is an organelle designed to perform photosynthesis, which only occurs in plant cells. Since only plant cells can undergo photosynthesis, only plant cells can contain chloroplast. Hence, according to this question, GRASS as a type of plant is an organism that will contain both mitochondria and chloroplast in its cells.
