The stages of mitosis are:
1. Prophase
2. Metaphase
3. Anaphase
4. Telophase<span>
Prophase
This is when the </span><span>centrioles separate and move to opposing sides of the cell.
Metaphase
This is when the chromosomes line up in the center of the cell and become connected.
Anaphase
This is when the</span><span> "sister" chromatids separate into individual chromosomes and are pulled apart.
Telophase
This is the last phase of mitosis, when chromosomes gather at opposite ends of the cell and new nuclear membranes form.
The answer is metaphase, because that is when the chromatids line up in the center of the cell.
Answer:
Metaphase</span>
Answer: The statement is TRUE.
Explanation:
Gram negative bacteria is a type of bacteria that possesses, from the interior to the exterior, a cytoplasmic membrane, a thin peptidoglycan layer, and an outer membrane containing lipopolysaccharide. The lipid portion of the lipopolysaccharide complex of the outer layer acts as an ENDOTOXIN.
The endotoxin of the gram negative bacteria can be detected in research or biomedical laboratories through a technique called LIMULUS AMEBOCYTE LYSATE test.
The test procedure follows a principle that the endotoxin of these gram negative bacteria are capable of forming gel clots (coagulation) of blood cell (amoebocytes) lysates of the Limulus polyphemus crab.
Therefore, If LAL (limulus amebocyte lysate) turns into a gel when exposed to a sample, it
means the sample is contaminated with endotoxins of gram-negative bacteria.
