The correct answer will be- the bark of an oak tree by Antonie Van Leeuwenhoek
Explanation:
The development of light microscopy began before the 18th century where a scientist named Antonie Van Leeuwenhoek observed the first living cells of the organisms.
Although the first cell was observed by the Robert Hooke when he observed the dead cells of the bark of a tree bu the light microscope designed by the Leeuwenhoek helped him to observe the living cells from the pond life and he also observed the bark of an oak tree.
Thus, the bark of an oak tree by Antonie Van Leeuwenhoek is considered the first cell.

The statement “Bones provide both structure and protection for the body.” is true because Bones indeed provide both structure and protection for the body.
Bones fulfill a dual role in the body, offering both structure and protection. They provide the framework that maintains the body's shape, allowing movement and providing stability. Additionally, bones act as a sturdy shield for vital organs, such as the brain, heart, and lungs, safeguarding them from external forces. Their protective function reduces the risk of injury to these delicate organs.
Bones serve as a mineral reservoir, storing essential minerals like calcium and phosphorus, which are released into the bloodstream as needed. They also house the bone marrow, where the production of red and white blood cells occurs, supporting the immune system and ensuring proper blood function. In summary, bones contribute to the body's structure, protect vital organs, store minerals, and produce blood cells, thereby maintaining overall health and well-being, the statement is true.

To living organisms, the most dangerous debris from tephra is probably volcanic ash, because it spreads so widely. Therefore, option B is correct.
Regardless of composition, fragment size, or emplacement process, tephra is the fragmented material created during a volcanic eruption. Pyroclasts is another name for airborne debris used by volcanologists. If clasts are not hot enough to fuse into pyroclastic rock or tuff after they have hit the ground, they stay as tephra.
Fine-grained material that is released during violent volcanic eruptions is known as volcanic ash. Volcanic ash particles have a diameter of less than 2 mm (0.08 inches). Volcanologists refer to any volcanic rock fragments, regardless of grain size, as "tephra" when they are created during an explosive eruption.
Thus, To living organisms, the most dangerous debris from tephra is probably volcanic ash, because it spreads so widely. Therefore, option B is correct.
