Select the correct statement regarding adipose tissue.
It is a form of dense connective tissue.
It is composed mostly of extracellular matrix.
Most of the cell volume is occupied by the nucleus.
Mature adipocytes are highly mitotic.
Its primary function is triglyceride storage.
Correct Answer : E
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.

Correct Answer is B
Explanation
A. Suicide rates do differ by gender and age but the statement about fathers and mothers does not align with typical statistics. Fathers and mothers are not usually the primary focus of such comparisons.
B. Statistics show that while women attempt suicide more frequently than men, men are more likely to complete suicide. This is often attributed to the methods used, as men typically choose more lethal means, resulting in higher completion rates.
C. Adolescent mothers and fathers are not typically the groups compared in this context. The frequency and success of suicide attempts are generally analyzed with a broader demographic perspective, not specifically focused on adolescent parents.
D. Adult men are more likely to complete suicide, but women generally attempt suicide more frequently than men. The completion rate for suicide is higher among men compared to women.
Correct Answer is C
Explanation
A. During depressive episodes, individuals often experience psychomotor retardation, which can manifest as slow and sluggish movements. In contrast, the manic stage is marked by heightened energy and activity levels.
B. Feelings of extreme sadness and hopelessness are characteristic of the depressive stage of bipolar disorder. During manic episodes, individuals typically experience elevated mood, which might be euphoric, irritable, or excessively optimistic, rather than feelings of sadness or hopelessness.
C. This is a hallmark of the manic stage of bipolar disorder. During a manic episode, individuals often have significantly increased energy levels, engage in numerous activities, and may exhibit restlessness.
This heightened activity can include impulsive or risky behaviors, excessive talking, and a reduced need for sleep.
D. Loss of appetite and weight loss are more commonly seen during depressive episodes of bipolar disorder. During manic episodes, individuals might experience an increased appetite or engage in disinhibited eating behaviors, which contrasts with the decreased appetite often observed in depressive stages.
