Answer:
Tetrad.
Explanation:
Tetrads may be defined as the stage of the division in which the cell contains the four spores in case of Ascus. The tetrad condition generally occurs in the meiosis division.
Tetrad stage are exceptionally found in the cocci or round bacteria. During tetrad stage, the bacteria divides in the square planar arrangement and forms the square of the four bacteria. This arrangement of four bacteria is the tetrad stage.
Thus, the answer is tetrad.
The answer is A. Speciation is the process by which new species are formed. It is an evolutionary process where certain biological populations evolve to new distinct species. It was the biologist Orator F. Cook who first coined this term. <span>There are types of speciation </span><span>namely</span><span> sympatric, parapatric, peripatric and allopatric.</span>
Answer:
1. Growth on cornmeal agar
2. KOH prep
Explanation:
Cornmeal agar is a nutritional deficient media containing :
- Corn meal 8g / zein 40 g / 100ml
- Agar 4g
- Distilled water 200 ml
- Large , highly refractory, thick walled.
KOH preparation (10 - 30% ) used to destroy keratin, leaves fungal hyphae.
- Can add a chitin-specific stain
- Calcofluor white fluorescent stain increases sensitivity
Hence the organism can easily be identified by these two tests.
Mitosis is process when a cell splits to create two identical copies of the original cell while meiosis cells split to form new cells with the usual number of chromosomes occurs for sexual reproduction while mitosis asexual reproduction
