Te answer would be <span>C. "Some mutations can be contagious, like infections.</span>" Mutations happen regularly and are often so subtle that we do not notice them on a daily basis. Some of them, however, can indeed cause harm.
Answer;
Gram staining procedure;
1. Flood slide with violet crystals and rinse
2. Flood slide with iodine and rinse
3. Decolorize and rinse
4. Flood slide with safranin and rinse
5. Blot slide
6. View slide under microscope
Explanation;
-Gram staining is a common technique used to differentiate two large groups of bacteria based on their different cell wall constituents. It is a procedure that distinguishes between Gram positive and Gram negative groups by coloring these cells red or violet.
Ionic bonds <span>are the type of bonds where there is </span>transfer<span> of electrons from one atom to another. The electrons are removed and from one atom and attached to another. A good example is salt which is composed of sodium and chlorine. Sodium readily loses one of its electrons and chlorine readily accepts it. Before losing the electron, sodium has a positive charge, but then becomes negatively charged after giving up the electron. Chlorine has a positive charge before gaining the electron but becomes negatively charged after gaining the electron. These opposite charges between sodium and chlorine attract the two elements together to form the ionic bond.</span>
The function of mitosis is for DNA to divide into two daughter cells during the cell division process.
Answer;
Two organisms that are placed on distantly spaced twigs on a phylogenetic tree are distantly related. They don't share the most recent common ancestor.
Explanation;
A phylogenetic tree is a diagram that describes the evolutionary relationships among carious species, based on the information available to and gathered by systematists. Should be viewed as hypotheses.
-The pattern of branching in a phylogenetic tree reflects how species or other groups evolved from a series of common ancestors. In trees, two species are more related if they have a more recent common ancestor and less related if they have a less recent common ancestor.
