Answer:
A. Lipid A
Explanation:
The outer membrane of Gram-negative bacteria is present outside to the thin peptidoglycan layer. The outer membrane consists of lipopolysaccharide (LPS) which is the molecule having both carbohydrates and lipids.
The lipopolysaccharide has three parts out of which lipid A is the toxin one. Lipid A is embedded in the outer membrane through its fatty acids. When lipid A enters the blood stream of the host cell, it leads to septic shock. Lipid A is heat stable and highly toxic.

Answer:
I answered 5 and 6
Explanation:
Prophase is where the nuclear envelope breaks down and chromosomes condense and become visible. Metaphase is where the chromosomes align in the middle of the cell, which in prophase, the newly visible chromosomes are scattered amongst the cells.
Interphase is the resting state of the cell, where a cell spends most of it's life in. But while it's active, cellular organelles double in number, the DNA replicates, and protein synthesis occurs.
The correct answer is C. Genetic analysis
Explanation:
In biology, two organisms have a phylogenetic relationship if they share a common ancestor and therefore have genetic similarities although in most cases there are also similarities in morphology, physiology, etc. However, two organisms might have similarities in morphology and physiology without genetic similarities. Due to this, if you need to determine whether two species are related or not the best method is a genetic analysis as only those organisms that share a common ancestor (phylogenetic relationship) are genetically similar.
