Answer:
multicellular.
Explanation:
Organisms exhibit various levels of organization of the body. It includes cellular level, tissue level, organ level, organ system level of organization. The unicellular organisms have single cells as their bodies and therefore do not have the genes that regulate the various parts of the body rather than the individual cells. Prokaryotic are unicellular organisms only and do not have multiple cells in their bodies. Therefore, the mentioned genes are the regulatory genes that coordinate the functioning of various parts of the body of a multicellular organism. For instance, the genes involved in regulation of blood glucose levels.
Answer:
Lungs supply oxygen carried by blood to cells of the body. The cells which are responsible for the transportation of oxygen is hemoglobin. When oxygen rich hemoglobin reaches a cell so the oxygen is unloaded and carbondioxide which is produced as a waste product is loaded in hemoglobin. Again this hemoglobin goes to the lungs and dispose carbondioxide there and repeat the process again.
Answer:
"Macrophages" cells are commonly dispersed (mixed in) with simple columnar epithelial cells. They are responsible for secreting mucus.
Explanation:
Answer: nucleotide A will bind to nucleotide T during DNA replication.
Explanation:
In DNA replication, Adenine(A) pairs up with its complementary base Thymine(T). The DNA polymerase which is an enzyme ensures that the nucleotide with base T binds to the base A of parental nucleotide.
