The hydrolysis of triglycerides on a spirit blue agar plate most closely resembles that of beta hemolysis on a blood agar plate.
The hydrolysis of triglycerides on a spirit blue agar plate is used for identifying bacteria based on what organic compounds they can break down, in this case lipids. Spirit blue agar is a medium that contains a supply of lipids. If bacteria have lipase, the enzyme capable of breaking down lipids spirit blue agar will be digested and it will appear as a halos around colonies of bacteria that make lipase.
The ability of bacterial colonies to induce hemolysis (the breakage of red blood cells) when grown on blood agar is used to identify microorganisms. Beta hemolysis is a complete lysis of red blood cells and in the blood agar, that area under the colonies that do the hemolysis appears lightened and transparent.
Answer:
The resolving power of an objective lens is measured by its ability to differentiate two lines or points in an object. The greater the resolving power, the smaller the minimum distance between two lines or points that can still be distinguished. The larger the N.A., the higher the resolving power.
Explanation:
1) D) transport water
2) A) transport sugar
3) D) transports fluids throughout the plant.
4) A) epidermal cells
5) B) parenchyma
6) A) collenchyma
7) C) sclerenchyma
Xylem is a specialized tissue in vascular plants that is primarily responsible for the distribution of water and nutrients from roots to stems and leaves. The xylem also provides mechanical support and storage to the plant.
Phloem is a specialized tissue in vascular plants that is primarily responsible for the distribution of food nutrients such as glucose (sugar) and amino acids from the leaves to various parts of the plant
The answer is C. A catalyst speeds up the rate of a chemical reaction. However, it is not consumed during the course of the day.
Answer:
Explanation:
The flatworms are acoelomate organisms that include many free-living and parasitic forms. Most of the flatworms are classified in the superphylum Lophotrochozoa, which also includes the mollusks and annelids. The Platyhelminthes consist of two lineages: the Catenulida and the Rhabditophora. The Catenulida, or “chain worms” is a small clade of just over 100 species. These worms typically reproduce asexually by budding. However, the offspring do not fully detach from the parents and therefore resemble a chain in appearance. All of the remaining flatworms discussed here are part of the Rhabditophora. Many flatworms are parasitic, including important parasites of humans. Flatworms have three embryonic tissue layers that give rise to surfaces that cover tissues (from ectoderm), internal tissues (from mesoderm), and line the digestive system (from endoderm). The epidermal tissue is a single layer cells or a layer of fused cells (syncytium) that covers a layer of circular muscle above a layer of longitudinal muscle. The mesodermal tissues include mesenchymal cells that contain collagen and support secretory cells that secrete mucus and other materials at the surface. The flatworms are acoelomates, so their bodies are solid between the outer surface and the cavity of the digestive system.
