Answer;
cells are very different but have similar properties
Explanation;
-Even though there are many different types of cells, they all share similar characteristics. All cells have a cell membrane, organelles organelles, cytoplasm, and DNA. All cells are surrounded by a cell membrane, all cells contain organelles, all cells contain cytoplasm and all cells contain DNA.
-Cells may differ in their number such that some organisms are made of only a single cell while other organisms are made of billions of cells
The scientist will add up the mass of the protons and mass
of the neutrons to come up with the approximate mass of atom because protons
and neutrons is what consist of the atoms. Therefore, in order to have the approximate
mass of an atom, adding the mass of protons and neutrons will give the result.
The answer is the third one, mitochondrial DNA can be traced for generations. this is because geneticists could trace back mitochondrial adam and mitochondrial eve.

The electrocardiogram most be affected by abnormally slow repolarization of ventricles SA node.
Repolarization occurs because of an growth in potassium permeability. on the SA node, potassium permeability may be further enhanced through vagal stimulation. This has the effect of hyperpolarizing the cellular and decreasing the charge.
The T wave represents ventricular repolarization. The T wave reveals a high quality deflection. The motive for that is that the ultimate cells to depolarize inside the ventricles are the primary to repolarize.
The SA node generates an electrical sign that causes the top coronary heart chambers to settlement. The signal then passes thru the AV node to the decrease heart chambers, causing them to contract, or pump. The SA node is considered the pacemaker of the coronary heart.
