Decomposers break down dead animals and plants. They usually benefit producers by releasing nutrients back in the soil.
Answer:
Skeletal muscles fibre are classified base on how the produce energy.
Explanation:
Skeletal muscles fibres consist of bundles of cells that form muscles which contain myobrills.
Skeletal muscles are classified based on how the produce energy;
Type 1 or slow pitch muscle fibres are more efficient and last for a long period of time. They are use for postural maintenance or endurance. It use aerobic respiration to produce energy or ATP.
Type 11 or fast twitch muscle fibres use anaerobic respiration and are for short speed and fatigue more easily than type 1.
Answers:
1. Facilitated diffusion: the process by which some molecules that are not able to pass directly through a cell membrane are able to enter the cell with the aid of transport proteins.
2. Osmosis: the diffusion of water molecules through a selectively permeable membrane.
3. Diffusion: the spreading out of molecules across a cell membrane until to they are equally concentrated.
Step-by-step explanation:
Diffusion is the spontaneous movement of molecules across a membrane from an area of high concentration to one of low concentration gradient.
Osmosis is the diffusion of water molecules across a semipermeable membrane from an area of low solute concentration to one of high solute concentration.
Facilitated transport occurs when molecules cannot diffuse directly through a cell membrane but can diffuse down a concentration gradient through transport channels in the membrane.
