Slants allows more surface area than a plate and prevents drying. Deeps provide more pigment. The primary use of broths is to grow a lot of bacteria.
like a petri dish, slant agar provides a solid surface for growth of bacteria. Unlike the petri dish the culture tubes are easier to store and transport. hope that helps
There are a few things that a primary producer could produce. This primary producer is the bottom of the food chain creating the food source.
chlorophyll because it is the the pigment that captures the suns energy and turns it in to glucose which is a sugar that the plants use for food
The first trophic level is a primary producer. The main purpose of these organisms is to produce things for other organisms to use.
primary xylem is primary in nature & is derived from procambium. But secondary xylem is secondary in nature and derived from fascicular cambium and interfascicular cambium. Primary xylem is differentiated into protoxylem and metaxylem, but secondary xylem has no such differentiation. In primary xylem vessels and tracheids are long and narrow, and vessels don't have tyloses, but in secondary xylem, vessels are blocked by tyloses, and vessels and tracheids are wider and shorter. Xylem fibres are more abundant in secondary xylem , and found in small numbers in primary xylem. Also unlike in primary xylem, secondary xylem has differentiated into sapwood & heartwood.
They are used to culture microorganisms and provide greater surface area for the growth of colonies.

Broth cultures are used to grow large numbers of bacteria in a small space
I used a lure to catch bonito fish ( at Blue Deeps)
Vegetarians only use vegetable broth, never a meat based broth.
The use of an artifact as a primary source is different than the use of a written primary source because when you exacavate for an artifact, you may have to make guesses. However, with a written primary source, you don't need to guess as the writing inside will have the answers to your questions or guesses.
You can quote something from your primary source and use footnotes.
Agar deeps are used to see whether an organism requires oxygen to grow. If there is spreading growth only at the bottom of the tube, the organism is an obligate anaerobe (meaning it cannot tolerate oxygen). If there is growth only at the surface of the agar, the organism is an obligate aerobe (it cannot grow without oxygen). And if there is growth all along the point of innoculation, the organism is a facultative anaerobe and can survive either way.
The importance of basins is that it is a region drained by a river system

Primary sources, secondary sources, and oral history.
Primary producers use the light and energy from the sun to produce energy. The primary producers sit on top of the trophic level and are mainly plants and algae.
