As the image or labels are not provided, lets generally look at structures which are common to all cells (eukaryoic)

Explanation:

The eukaryotic cells can be divided into two main types: plant cell and animal cell.

The similar structures in both of these cells include:

Cell membrane: The covering which is semi- permeable and protects the cell from the external environment.

Cytoplasm: The fluid in which all the organelles of a cell float.

Vacuole: Storage house of a cell.

Nucleus: The are where all the hereditary material exists.

Ribosomes: Organelle where proteins are made.

Endoplasmic Reticulum: Also associated with the making of proteins.

Golgi-complex: Area where proteins are modified and packaged.

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
