Answer:
B.Active transport, because energy is being used to move molecules against the concentration gradient
Explanation:
Substances move in and out of living cells through various transport means. Some substances move passively (without energy) while others move actively (with energy). Active transport of substances involves the movement of molecules against the concentration gradient.
Active transport moves against concentration gradient in the sense that the movement occurs from a region which is less concentrated to one which is more concentrated, hence, energy input in form of ATP is required for such transport to occur. This is the case of the cellular transport in the diagram. Therefore, it is an ACTIVE TRANSPORT because energy input (ATP) is required.
Note, Osmosis and facilitated diffusion are types of passive transport that requires no energy to occur.
Answer:
1. Muscle: soft, contractile tissue important to produce force and motion in animals.
2. Fascicle: multiple bundles of skeletal muscle fibres which is surrounded by a type of connective tissue called perimysium.
3. Muscle fibres: bundles of cylindrical organelles myofibrils formed by the fusion of myoblasts via myogenesis process.
4. Myo-fibril: basic unit of a muscle cell made of thick and thin myofilament arranged in parallel columns along the length of muscle fibres.
5. Myo-filament: strands of actin and myosin proteins which pack a muscle fiber and are force generating structures.
