Answer:
Damage to the heart muscle
Answer and Explanation:
When a cell is freezed, it cytoplasm-which is mostly water- is frozen and its volume expands. In consequence, pressure inside the cell increases and that causes damage to the outer wall.
The same occur in an unopened softdrink when it freezes. The volume inside the container increases and the pressure increases. If this volume increment is not considered before freezing the liquid, it could cause the container damage or breaking.
Conventional genetic analyses of prions involving rrna sequences are impossible because Prions do not contain nucleic acids
The name "prions" refers to aberrant, pathogenic agents that are transmissible and capable of inducing improper folding of specific normal cellular proteins known as prion proteins, which are abundant in the brain.
Prions are virus-like creatures that contain a prion protein. These elongated fibrils (green) are thought to be protein aggregations from the infectious prion. Prions cause neurodegenerative brain illness by attacking nerve cells. Symptoms of "mad cow" include glassy eyes and uncontrollable bodily trembling.
Prion disorders develop when normal prion protein, which is found on the surface of many cells, becomes aberrant and clumps in the brain, causing harm to the brain.

Explanation:
Weathering can be defined as the physical disintegration and chemical decomposition of rocks and structures to form sediments and soils. Physical weathering is also known as mechanical weathering which involves the breakdown of materials physically.
In chemical weathering materials reacts decay via formation of chemical substances. It occurs by oxidation, solution, hydrolysis, carbonation, e.t.c
The minerals in a marble statue react with water to form acids and pores in the structure.
Chemical weathering
A piece of rock crumbles after being constantly thrashed by strong waves.
Mechanical weathering
Industrial runoff forms cracks in a rocky structure in its path.
