Answer:
Presence of papillary muscles
Explanation:
- Papillary muscles are structural components of the ventricles.
- They are attached to the cusps of the mitral and tricuspid valves through connective tissue strings known as the cordinae tendeneae (heart strings).
- These muscles prevent the prolaspse of these valves during ventricular systole.
- Although they differ in number i.e. two in left and three in right ventricle, papillary muscles are present in both ventricles.
Independent, dependent, and controlled variables.
Answer:
I would say that A is the correct answer. Foods release amino acids. Hope this helps. :D
Bipedalism is the characteristic that hominins have and sets them apart from other primates. Bipedalism refers to locomoting. It is walking primarily upright on two feet, movement on two feet.
Walking upright distinguishes humans from other primates. Walking<span>, </span>running<span>, or </span>hopping are types of bipedal movement.
Answer:
Homeostasis is the process to maintain balance in body. Homeostasis in sugar can be maintained by two pancreatic hormones-
1-Insulin
2-Glucagon
Explanation:
Insulin - secreted by beta cells of islets of langerhans in pancreas. It lowers blood sugar level when high concentartion of sugar is present in blood. It converts sugar to glycogen by the process of GLYCOGENESIS. It allows insulin receptors on hepatic cells to absorb glucose molecules from blood. To lowers the glucose concentration in blood stream.
Glucagon - secreted by alpha cells of pancreas. It increases blood sugar level when sugar level is low in blood. Glucagon converts glycogen into glucose. Stored glycogen can be reconvert into glucose molecules with help of this hormone. this process is known as glycogenolysis. When blood sugar concentration is low in blood stream.
<em>With the equilibrium between these two hormones homeostasis is maintained through blood sugar project in body</em>
