Transporting oxygen is primarily the function of the circulatory system, not the muscular system.

The plasma membrane does not produce energy; it primarily functions as a barrier and facilitates transport and communication.

The skeletal system does not secrete hormones; this function is primarily associated with the endocrine system.

The stem does not absorb water; this function is primarily performed by the roots.

The stem does not absorb water; this function is primarily performed by the roots.

Glucose is a carbohydrate, not a lipid.

Viruses are not considered living organisms as they cannot carry out metabolic processes on their own.

Photosynthesis is a process that converts light energy into chemical energy, not a mechanism of water transport.

Skin color in humans is a polygenic trait and does not follow Mendelian inheritance patterns.

Thermogravimetric analysis (TGA) is not a method for measuring surface area; it is used to study thermal stability and composition.

Cross-fertilization involves the fusion of gametes from two different individuals, hence it is not asexual.

The menstrual cycle is a natural process and not a method of contraception.

Transfection is a method primarily used in animal cells, while the other methods are commonly used for gene transfer in plants.

Photosynthesis is a process that converts light energy into chemical energy, not a method of water transport.

Increasing the temperature generally decreases the adsorption capacity for physisorption, as it can overcome the weak van der Waals forces.

A typical flower consists of stamens, carpels, petals, and sepals, but not leaves.

The cell theory states that all cells arise from pre-existing cells, not spontaneously.

The anther is part of the male reproductive structure (stamen) and is not part of the female reproductive structure.

The anther is part of the male reproductive structure (stamen) of a flower, while stigma, style, and ovary are parts of the female reproductive structure (pistil).

Viruses are not included in the five-kingdom classification as they are not considered living organisms.

The root is not a part of the flower; it is part of the plant's root system.

The ovary is not a part of the male reproductive system; it is part of the female reproductive system.

Fossil fuels are not products of biotechnology; they are natural resources formed from ancient organic matter.

Glucose is not a product of cellular respiration; it is a reactant that is broken down to produce ATP, water, and carbon dioxide.

Sugar is not a product of microbial fermentation; it is a substrate that microbes ferment.

Glucose is not a product of respiration; it is a reactant that is broken down during the process.

Brittleness is not a property of metals; they are typically malleable and ductile.

Nitrogen is colorless, odorless, and diatomic, but it does not support combustion.

Thermoplastics are generally not brittle at room temperature; they can be reshaped upon heating.

Tuberculosis is primarily a respiratory disease and is not classified as a sexually transmitted disease.
