Answer:
Gram-negative bacteria are bacteria that do not retain the crystal violet stain used in the Gram staining method of bacterial differentiation. They are characterized by their cell envelopes, which are composed of a thin peptidoglycan cell wall sandwiched between an inner cytoplasmic cell membrane and a bacterial outer membrane.

Second stage of cellular respiration is
The stage happens in mitochondria.
Oxygen combines with small molecules.
Energy is released.
<u>Explanation:</u>
Krebs cycle is the another name for second stage of cellular respiration . Throughout this stage, pair of molecules of ATP are generated. Another energy-storing molecules are also produced. Into the mitochondrial matrix which is the deepest part of mitochondria, all pyruvate from glycolysis (from first stage) moves.
The Krebs cycle lacks oxygen. Anything that requires oxygen is represented as aerobic. The oxygen blends with the carbon from the pyruvate molecules. This creates carbon dioxide, a waste product. As a result of second stage NADH is generated.
Solution:
Plant and animal cells both undergo in mitotic cell divisions. The main difference is that how they can form the daughter cells during cytokinesis. During that stage, animal cells form furrow or cleavage that gives way to formation of daughter cells. While, during telophase, plant cells phragmoplast forms in the center of the cell.
Animal cells have centriols that helps the organization of mitotic spindle and completion of centrioles. But plant cell don’t have centrioles.
Animal cells divide at anywhere and all the time while the plant cell is divide only in specialized region known as the meristems.
Answer:
Heart attack is when a coronary artery gets block, thus stopping blood supply to part of the heart that coronary artery supply.
Coronary artery disease is a collection of coronary blockage disease that causes heart failure.
