Answer:
The correct option is D. The nerve and red blood cells will turn on and off different portions of their DNA, using different genes to make different proteins.
Explanation:
A zygote is totipotent which means it has the ability to differentiate into any cell type found in the body along with the placental cells.
The nerve and red blood cells are specialized cells and they cannot differentiate into any other cell type.
All cells in the body are formed from the zygote. All the cells in the body have the same chromosomes and the same genes. However, these cells become specialized because certain part of the DNA is activated in one type of cell which helps it perform its function. Different genes are activated in different specialized cells which are able to transcribe and translate.
Answer: cellular respiration happens in the mitochondria and cytoplasm of cells.
Explanation: many organisms, including plants and plankton, per- form oxygen-dependent cellular respiration.
Persons with O blood have neither antigen a nor antigen b on their red blood cells but have antibody anti-a and antibody anti-b in their plasma.
ABO blood grouping was discovered by Austrian scientist Landsteiner. It consist of four blood groups- A, B, AB, & O.
Red blood cells have certain extension of the proteins that are called antigen. Two types of antigens are there antigen a & b. The RBCs which have a particular antigen will not have the antibody against the same.
Blood Group A has antigen A and antibody B. Blood group B has antigen B and antibody A. Blood group AB has both antigen and no antibodies while blood group O has no antigen and antibody A & B.
