The first step in the titration process is; A measured volume of an acid or base of (un)known  concentration is added to a flask. The second step is several drops of indicator are added to the solution, and the third step is ; the measured volumes of a base or acid of known concentration are added, using a burette, until the indicator just barely changes color (end point or the equivalence point).

Which organelles are found in a plant cell? Check all that apply. Endoplasmic reticulum centrioles cell wall vacuoles lysosomes
Shalnov [3]

Answer: Endoplasmic reticulum, cell wall, vacuoles, lysosomes, mitochondria, chloroplasts and cell membrane.    

Explanation: Following are the organelles found in plant cells.

Endoplasmic reticulum is the membrane bound organelle found in both plants and animals cells. The endoplasmic reticulum forms a network of canals it helps in transport of material in and out of the cell.

Cell wall is a rigid structural layer which forms an envelope around a cell. It is a rigid structural layer which is composed of cellulose. It provides protection to the cell and exhibit pores which facilitates the transfer of materials to pass to and from the cell membrane.

Cell membrane is a layer that surrounds the cell and separate it from the external environment. It is a selectively permeable structure which controls the material which is going in and out of the cell.

Vacuoles are membrane bound fluid filled organelles which store materials which are not required by the cells and helps in the waste disposal. They store materials like water, food, sugars, minerals and other waste products.

Chloroplasts are the organelles specifically found in the plant leaves. They have special pigment called as chlorophyll that traps the light energy from sun to conduct photosynthesis.

Mitochondria are tube like organelles these are the called as the powerhouse of the cell. Their function is in cellular respiration. They break the sugar molecules to produce ATP as a source of energy.

Lysosomes are the small sac like structures they exhibit a single membrane which contains strong enzymes which are capable of digesting cellular wastes. They also called as suicidal bags.

Centriole is an organelle which is not found in the plant cell. It is only found in the animal cells, their is a pair of centriole,  which are minute cylindrical organelles near the nucleus. These helps in the development of spindle fibers during cellular division.

How can you reconcile this observation with the cause of death being hypoxia?
Neko [114]
Death by hypoxia can be caused by airway obstruction(strangulation) or poison(cyanide, CO).
In the case, there is a toxicology report saying the victim is poisoned by cyanide. The organ damaged also diffuse and not concentrated. Cyanide works by inhibiting an enzyme in the mitochondria that use oxygen. Therefore, the cells can't oxygen for cellular respiration, cause the tissue die of hypoxia. The oxygen is there but it can't be used. The laboratory report that found high oxygen level in the blood also supports the cyanide poisoning.
