The right option is; glucose
Glucose is the biological molecule that is smallest due to being a subunit rather than a macromolecule.
Glucose is a simple sugar (monosaccharide), a sub unit of carbohydrates. Glucose is the most significant energy source in all organisms. It is the most abundant carbohydrate and it is mainly present in foods rich in carbohydrates, such as rice, potatoes, and fruit. Glucose is also produced by plants and most algae during photosynthesis.
Answer:
True, by active transport
Explanation:
The influx and efflux of molecules through the cell membrane depend on the concentration gradient.
When the molecules down their concentration gradient that is from higher concentration to lower concentration are known as passive transport but sometimes the cell has to transport the ions against the concentration gradient.
When the ions move against the concentration gradient, they use energy in the form of ATP molecules and then transport the ions. This is known as active transport.
In the given question, since the sodium ions move inside the cell against the concentration gradient by the active transport.
Answer:
Explanation:Many traits vary among different members of a population of humans and animals, from body size to hair colour, and those differences are often linked to differences in genes. Natural selection occurs when some of those traits help some individuals survive and reproduce more than others
Answer:
Invertebrates include all animals that lack a backbone, or a vertebral column. All chordites exhibit four characteristics during at least one stage of life: a dorsal, hollow nerve chord; a notochord; a tail that extends beyond the anus; and pharyngeal pouches.
