Select the correct statement regarding adipose tissue.

A. Delirium is characterized by a sudden onset of confusion and changes in mental status, often occurring over a short period (hours to days). This contrasts with dementia, which has a gradual onset and progressive decline in cognitive function over months or years.
B. In delirium, the ability to perform activities of daily living (ADLs) is often affected because cognitive and attentional impairments can interfere with daily functioning. In contrast, early stages of dementia may still allow for relatively intact ADLs, and in depression, ADLs might be affected due to lack of motivation or energy rather than cognitive impairment.
C. Delirium typically involves visible, pronounced cognitive changes and fluctuating levels of awareness and attention. Clients with delirium usually exhibit overt confusion and disorientation. In contrast, in dementia, cognitive changes are progressive and become more apparent over time.
D. An apathetic demeanor or flat affect is more commonly associated with depression, where mood disturbances such as sadness, lack of motivation, and diminished emotional expression are prevalent. Dementia might also involve changes in affect, but apathy and flat affect are not distinguishing features of delirium.

A. Adipose tissue is not classified as dense connective tissue. Adipose tissue, on the other hand, is a type of loose connective tissue that is primarily composed of adipocytes (fat cells) and has a relatively sparse extracellular matrix compared to dense connective tissues.
B. Adipose tissue is composed mainly of adipocytes (fat cells), which occupy most of the tissue’s volume. The extracellular matrix (ECM) in adipose tissue is relatively minimal compared to other types of connective tissue.
C. In adipocytes, most of the cell volume is occupied by a large lipid droplet rather than the nucleus. The nucleus is relatively small and located at the periphery of the cell, while the central portion of the cell is primarily filled with fat storage.
D. Mature adipocytes are not highly mitotic. Adipocytes have a limited ability to divide. Instead, the number of adipocytes can increase primarily through the differentiation of precursor cells (preadipocytes) into mature adipocytes, not through the division of existing adipocytes.
E. The primary function of adipose tissue is the storage of triglycerides (fats). Adipocytes store energy in the form of triglycerides, which can be mobilized when needed for energy. Additionally, adipose tissue plays roles in insulation, cushioning, and hormone production, but triglyceride storage is its main function.
