Deoxyribonucleic acid (DNA) is the genetic information of most living organisms (on the other hand, some viruses, retroviruses, use ribonucleic acid (RNA) as genetic information).
- DNA is a polymer, made of units called nucleotides (or mononucleotides).
- The nucleotide consists of a phosphate + a sugar + a nitrogenous base. In DNA, the nucleotide is a deoxyribonucleotide (in RNA, the nucleotide is a ribonucleotide).
Answer:
The correct statements are B, D and F
Explanation:
The following statements that correctly describes T tubules and their role in conducting action potentials in muscle cells are;
i) T tubules are infoldings of the plasma membrane that encircle the myofibrils and are in contact with the sarcoplasmic reticulum.
ii) T tubules carry action potentials into the interior of the muscle cell via voltage-gated Na+ and K+ channels.
iii) Without T tubules, the muscle cell would not be able to contract.
Do various minerals effect the rate at which it takes for ice to melt? This is a scientific question that science could test because rate/speed can be scientifically measured.
Bone marrow contains stem cells. stem cells can develop into red blood cells (carry oxygen), white blood cells (provide immunity), and platelets (aid in clotting)
if the bone marrow is destroyed or does not function properly leukemia (cancer causing abnormal white blood cells) or aplastic anemia (bone marrow doesnt make red blood cells) could develop.
