Proteins that are postsynaptic get neurotransmitters given by the presynaptic proteins.
The potential sources of measurement error for muscular endurance tests are Equipment, technical skill, client factors, or environmental factors. Client factors are items that can be avoided with adequate testing preparation.
Strength training and development are thought to be crucial for improving the physical health of the population as well as for providing support and maintaining good posture. It is a fact that people need strength for their daily activities, and some of these physical efforts are sustained for extended periods of time. When assessing the musculoskeletal functions and physical capacities of the population, it is vital to take into account this physical ability because it has grown to be a significant factor in the physical condition.

Trees soak up rain from the ground and store/use it. Without trees to soak up the water on the ground, it stays put > pools > floods.
Also, a little bit of rain stays on the trees' leaves. This may not seem like a lot, but there are many trees in a forest with many many leaves all holding water :)
Answer:
e) Substrate
Explanation:
An enzyme substrate binds to the enzymes active site which speeds up a reaction, forming an enzyme-substrate complex. Enzyme catalyzes the reaction and form a product from a specific substrate resulting in an enzyme-product complex. They are highly specific and each can only catalyze and bind to its own specific substrate or reactant.
Eg; Starch is a substrate (reactant) which is converted to maltose!(Product) by amylase enzyme.
Answer: Large molecules and wastes move through the membrane through forms of active transport- endocytosis and exocytosis.
Explanation:
Molecules are moved across the cell membrane via different mechanisms like diffusion, facilitated diffusion and passive transport; however, some very large molecules require specialized types of active transport to cross over- these are endocytosis and exocytosis.
During endocytosis large molecules cells and cell fragments moved across the plasma membrane through a process of <em>invagination;</em> piece of the external cell membrane falls into itself and forms a small pocket that surrounds the target molecule this breaks off from the membrane to form an intracellular vesicle. Different methods of endocytosis such as <em>phagocytosis, pinocytosis </em>and receptor-mediated <em>endocytosis</em>, take in cells, water and targeted substances respectively.
Like endocytosis, the particles (signal proteins, neurotransmitters and waste material) are surrounded by a phospholipid membrane. However, in exocytosis, this membrane is formed in the cytoplasm, and merges with the plasma membrane’s interior in a process <em>opposite to </em>endocytosis; material is removed from the cell and exported into the cell’s exterior called the extracellular space.
