Answer: Divergence
Explanation:
One postsynaptic cell has the ability to receive the input from large number of different presynpatic cells and the divergent neurons can have connections with different postsynaptic cells.
The divergence in the neurons allows one neurons to have communication with the other neurons within a network.
The divergence neurons can communicate with any of the neurons (output) in the network.
Answer:
Pyramid is a good representation of energy flow in an ecosystem because the shape of pyramid is wider at the bottom and pointed at the top. In the ecosystem, population of plants are maximum so it is placed at the bottom of the pyramid while the organisms such as tertiary consumers are placed at the top of the pyramid due to low in population. So pyramid is a good representation.
Answer: Skeletal Muscle
Explanation:
Skeletal muscle is a form of "striated" (striped) muscle tissue. It is under the voluntary control of the somatic nervous system. Most skeletal muscles are attached to bones by bundles of collagen fibers known as tendons.
<span>Protein channels are needed to transport substances because it accelerates the transport process. Very few substances enter or leave cells without being attached to a transport protein. Different types of substances require different types of proteins to transport them. Protein channels transport water or ions downwards and ATP-powered pumps transport molecules or ions upwards. ATP generates energy to transport the molecules upwards. Gravity is used to transport the water molecules downwards. So, in a nutshell, if substances need to be transported from the top of the body downward, the force of gravity is used to transport the substances down. If substances need to be transported upwards, ATP, a coenzyme, is used to generate energy to transport the substance upwards</span>
