Endoplasmic Reticulum is a long piece of membrane inside of the cytoplasm in a Eukaryotic cell. It connects to the Nuclear Membrane as well. It has numerous ribosomes attached as it helps with protein and lipid synthesis. It has both smooth and rough forms, each which do different things inside the cell.
The synaptic pruning during childhood results in a reduction in density of nerve cells, thus increasing the brain's efficiency.
<span>Synaptic pruning, which can include both axon and dendrite pruning, is the process of synapse elimination that occurs usually in early childhood. It is thought that this is the brain’s way of removing connections in the brain that are no longer needed and a way of maintaining more efficient brain function.</span>
Passive transport<span> is a movement of </span>biochemicals<span> and other </span>atomic<span> or </span>molecular<span> substances across </span>cell membranes through <span>concentration gradients</span><span> without need of </span>energy<span> input. Unlike </span>active transport<span>, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in </span>entropy<span>. The rate of passive transport depends on the </span>permeability<span> of the cell membrane, which, in turn, depends on the organization and characteristics of the membrane </span>lipids<span> and </span>proteins<span>. The four main kinds of passive transport are simple </span>diffusion<span>, </span>facilitated diffusion<span>, </span>filtration<span>, and </span>osmosis.
The development of electronic delivery systems advancements in the music industry has preserved resources and reduced waste.
Option C
<h3><u>Explanation:</u></h3>
Music industry is the industry that deals with the production of new music that are soothing to hear, recording them, spreading them in public and so on. This industry is an age old industry which used to record music in different ways in past. Most of them were not that efficient to capture the individual tunes of the music and moreover they used the resources very inefficiently.
With the advent of modern day electronic delivery systems, the mics came into market, as well as different electronic media like pendrive, CD's, tape recorders, and even internet through which music can be spread among public very easily.
