Answer:
False
Explanation:
Cytosine, guanine, thymine, and adenine are collectively referred to as nitrogenous bases. These are not phosphates. The cytosine, guanine, thymine, and adenine are the four different types of nitrogenous bases. These nitrogenous bases are present in the deoxyribonucleotides. Cytosine and thymine are smaller in structure and have single ring structures. These are collectively called pyrimidines. On the other hand, adenine and guanine are the larger nitrogenous bases each with double ring structures. They are collectively called purines
Answer:
Tubercle: allows tendons to attach to bone
Foramen: Allows blood vessels and nerves to travel through bone.
Fossa: Allows to bones to form a joint.
Explanation:
The tubercle or tuberosity in the human seletal system, is a protrusion that allows for attachment of skeletal muscles. The muscles attach by tendons, where the enthesis is the connective tissue between the tendon and bone.
Foramina inside the body of humans and other animals typically allow muscles, nerves, arteries, veins, or other structures to connect one part of the body with another.
Answer:
Sigma factors bind to the promoter region of a particular gene and facilitating the binding of RNA Polymerase to the promoter region (formation of the RNA polymerase holoenzyme complex) in order initiate transcription of the gene.
Put simply - Helps RNA Polymerase do it's job.
Glucagon works to counterbalance the action of insulin . About four to six hours after you eat , the glucose Levin your blood decrease, triggering your pancreas to produce glucagon this hormone signal your liver and muscle cells to change the storage glycogen back into glucose.
