Explanation:
Correct on Edg; A Local Area Network (LAN) only works in a limited geographical range. A Wireless Local Area Network (WLAN) is the same, except that you can use it without the use of wired connections such as Ethernet cables. A Wide Area Network (WAN) allows you to reach a wider geographical range and often involves satellite signals and phone lines to connect devices over long distances.
Answer: d. C (parent rock)
Soil horizons are the layers lying parallel to the surface or subsurface layers of soil. These horizons are formed in the process of soil horizon. These sequence of soil horizons is collectively called as soil profile.
The layer or soil horizon, which is least likely to be penetrated by plant roots is C horizon. The C horizon is a layer of soil, which consists of huge aggregates of parent rocks, which are unweathered or partially weathered, lying deep in the bottom of the soil profile. It does not contain organic matter. Also, the texture of the soil is not fine, instead hard rocks are present. Therefore, this layer of soil cannot be penetrated by plant roots.
Colloids are mixtures in which one or more substances are dispersed as relatively large solid particles or liquid droplets throughout a solid, liquid, or gaseous medium. The particles of a colloid remain dispersed and do not settle due to gravity, and they are often electrically charged.
Should be the center, cuz that's the reaction that powers the sun.
