Topsoil is the A horizon in figure 7-1.The most leaching of minerals occurs from the A horizon into the B horizon. The C horizon shown in figure 7-1 is most like the parent soil, and <span>the A horizon in figure 7-1 contains the most humus.</span>
Answer:
Phase of the cell cycle in which cells grow, duplicate organelles, and synthesize DNA.
S phase
Explanation:
DNA replication occurs in synthesis or in the S phase of the cell cycle. Each chromosome is copied with high fidelity in a process that involves a large number of enzymes. In this process the double strand of DNA breaks down and each individual strand is used as a template for the production of the complementary one. The result is the production of two identical copies of the genetic material.
Answer:
Endospores Staining
Endospores are substances that are formed inside of specific bacterial cells which boost their survival rate in times of harsh conditions.
Gram staining alone is not sufficient to observe the endospores, which seems apparently clear when Gram-stained cells are observed.
Endospore staining employs two stains to identify endospores from other cell components.
•The Schaeffer-Fulton method employs heat to promote the primary stain (malachite green) into the endospore. Rinsing with water will well wash away the colour from the cell, as the endospore still appears to be green stained. Counterstaining pink with safranin will show the shape and location of endospores, if they are a part of the cell. The green endospores will be seen inside the pink vegetative cells or it will appear distinct from the pink cells in total. If no endospores are seen, only the pink vegetative cells will be observable.
The attached image shows a stained preparation of Bacillus subtilis revealing the endospores as green and its vegetative cells in pink coloration.
Endospore-staining procedures are essential for observing Bacillus and Clostridium, two genera of endospore-forming bacteria, production of bioterrorism agent from B. anthracis (which causes anthrax.
Answer:
- Soil knife to make digging the soil easier
- Handheld pruners to fix and prune the plants of your garden
- Gloves to keep your hands save from any harmful or chemical substance.
- Binder twine to maintain the plants (to tie their stems together)
- A notepad and pen to check the progress of your plants (e.g.: you might need to note down whether a plant may need more water or nutrients (mineral ions), if you see a plant almost wilting, appropriate actions must be taken so notepad and pen can help you track this down, so that you can get the appropriate resources needed)
