When burning, Yes.
A normal fire in a steel-frame building can soften the structure to the point of collapse.
Building laws / regulations require that all the structural steelwork is either covered in a protective coating (such as intumescent paint) or boxed in with fire-resistant plaster, so the fire can be extinguished before the building is weakened - or at least give people time to get out.
If that coating or plaster is damaged by impact or an explosion, the steel is exposed and the building can collapse relatively quickly.
(The common intumescent coatings just look like paint until exposed to fire, so the steelwork may appear to have no particular protection - but it always does).

See the images below - small buildings with steel-frame roofs after fires; you can see the amount of "sagging" and distortion on structures that have no particularly high loads.
These have burned long enough to destroy any protection, or they did not have any as the structure does not support occupied space.

Answer:
Biological
Explanation:
Memory allows for the storing and retrieval of information after seconds to years and is important for everyday life.
Progress in understanding memory function can be supported by first diagnosis of dementia, mild cognitive impairment, natural ageing, schizophrenia, and stroke.
Understanding the biological basis of learning, memory, behaviour, perception and consciousness has been described as the biological sciences greatest challenge.
Answer:
Option B: compounds
Explanation:
Elements can be chemically combined into compounds, therefore, a compound consists of two or more elements combined, in fixed rstios, by chemical means.
Answer:
D) Her success in extracurricular activities
Explanation:
In this scenario, Joni wants to become a receptionist at a local hospital, which requires abilities such as good interpersonal skills and excellent communication abilities and other personal attributes that are important in an environment that involves dealing with patients, such as kindness and the ability to display empathy.
From these options, her graduation rank, religious affiliation, or bilingual / multilingual capabilities are not as important as <u>her success in extracurricular activities because the latter usually involve high levels or socialization and allow an individual to develop good communication skills.</u>
It is important to mention that this also depends on where Joni is located as well, for instance, if this hospital is located in an area with a high level of diversity (e.g. London or Los Angeles), <u>her ability to speak more than one language would also be highly relevant.</u>
