Answer:
Internal environmental factors are events that occur within an organization. External environmental factors are events that take place outside of the organization and are harder to predict and control.
As students observe several slides of tissue cross-sections, one simple key they can use to determine if the slides come from dicots or monocots is to analyze the <em><u>vascular bundles</u></em><em><u>.</u></em>
A vascular bundle is described as a portion of the transport system of vascular plants. These bundles are microscopically different in Monocots than they are in Dicots, which will allow students to tell them apart through the tissue slides.
The difference is that monocots contain <em><u>randomly scattered </u></em><em><u>bundles </u></em><em><u>located throughout the </u></em><em><u>stem</u></em><em><u>.</u></em> On the other hand, <u>dicots </u><em><u>have their vascular </u></em><em><u>bundles </u></em><em><u>more neatly organized in </u></em><em><u>concentric circles</u></em><em><u>.</u></em> These microscopic differences can serve as a key to be used by the students to classify the tissue samples they are studying.

Answer:
PCR is a tool used in molecular biology and Recombinant DNA is a technology, while developing technology various tools are used, for example our case the tools are vectors, ligation and Restriction digestion enzymes etc. PCR is the abbreviation for polymerase chain reaction. It is similar to recombinant DNA technology in that both have the ability to sequence DNA.
Answer:
Due to information about the earth history.
Explanation:
There is a great significance of the fossils that preserved in the Dove Spring Formation in order to our understanding of Earth’s history because these fossils provides a lot of information about the history of the earth. Dove Spring Formation (DSF) is an 1,800-m-thick succession of fluvial, lacustrine, and volcanic rocks that comprise of diverse vertebrate fossil collections that provides information and knowledge about the different organisms present in the history of earth.
