Sergio [31]2 years ago

Plant cells are surrounded by a tough extracellular matrix in the form of a cell wall, which is responsible for many of the unique features of a plant's life style. The cell wall is composed of a network of cellulose microfibrils and cross-linking glycans embedded in a highly cross-linked matrix of pectin polysaccharides. In secondary cell walls, lignin may be deposited. A cortical array of microtubules can determine the orientation of newly deposited cellulose microfibrils, which in turn determines directional cell expansion and therefore the final shape of the cell and, ultimately, of the plant as a whole.

Which observation would be the best evidence of the water cycle
Troyanec [42]

Founder effect or population bottleneck refer to events which bring about reduction in the genetic variability of a particular specie population. Such events typically drastically reduce the gene pool of the population and produce a smaller number of population with less genetic diversity. An example of a population bottleneck is a genocide event. Such event will destroy a large percentage of the affected population leaving only a smaller population with less genetic diversity. i hope these helps.

Luda [366]

Answer: Wide Area Network (WAN)

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.
