Answer: B. DNA polymerase checks for errors in base pairing as it helps new DNA strands form.
Explanation: DNA polymerase is an enzyme that catalyzes the synthesis of a new DNA strand from a DNA template. This process is known as replication. During replication, DNA polymerase rejects incorrect bases before the phosphodiester bond is formed because it has a 3' -> 5' exonuclease activity that double checks every nucleotide that is added to the growing strand. This check allows the enzyme to remove a newly added mismatched base pair.
Answer:
When ants are removed their preys population will get bigger.
Answer:
ability to differentiate into other cell types during cell division i.e. totipotent nature
Explanation:
Stem cells are undifferentiated cells with the unique ability to develop into specialized cell types in the body during early life and growth through the process of cellular differentiation. When a stem cell divides, each new cell has the potential to either to remain a stem cell or become another type of cell with a more specialized function e.g muscle cell, red blood cell or a brain cell.
Stem cells provide new cells for the body as it grows, and replace specialized cells that are damaged or lost. This ability of stem cells to differentiate into a variety of cell types in an organism including embryonic tissue, is an important distinguishing factor. They have two unique properties that enable them do so:
1. They can divide over and over to produce new cells
2. As they divide, they can change into the other types of cell (cellular differentiation).
It produces lymphocytes, is important for T cell maturation (T for thymus-derived). The spleen is an organ in the upper left abdomen, which filters blood, disposes of worn-out red blood cells, and provides a 'reserve supply' of blood. It contains both red tissue, and white lymphatic tissue. Hope that helped!
Answer:
Horizontal gene transfer.
Explanation:
Horizontal gene transfer happens when an organism acquires a gene that benefits its development. This individual then can transfer this information to another cell without it being its breed or duplicate. Normal gene transfer happens "vertically" from a parent to a daughter cell, but in this case, duplication is not needed for another organism to acquire the gene.
