Answer:

b) epigenetics.

Explanation:

Epigenetics simply indicates the changes that do not alter the DNA sequence but influence the way genes are intercepted by the cells. Chemical compounds externally applied to single genes may modify their activity and these changes are known as epigenetic changes. Epigenetic variations persist as cells divide, and in some cases can be passed from one generation to another. The epigenome may also be influenced by environmental factors, for example, diet, exposure to contaminants, etc.

Summarize why 1917 is a turning point in World War 1.
Ivan

Answer:

The entry into the war of the USA with its enormous resources in spring 1917 led to the conflict taking a clear and critical turn in favor of the Western Powers. The decision of the German high command to pursue the war at sea was also a demonstration of Emperor Karl's powerlessness. 1917 saw the entry of America into World War One, the result of Germany's use of unrestricted submarine warfare. 1917 also saw the start of the Battle of Passchendaele, also known as the Third Battle of Ypres.

Which of the following statements is true? a. carbohydrate rich meal increases insulin secretion b. a protein rich meal increase
mrs_skeptik [129]

Answer:

E- All of the statements are true

Explanation:

Insulin and Glucagon are hormones, both secreted by the pancreas.

Insulin functions in the conversion of carbohydrates to glycogen which is stored in the body as glucose reserves. This implies therefore that:

  • A carbohydrate rich meal will stimulate the increased production of insulin.

Glucagon on the other hand, works to breakdown the glucose reserves in situations such as fasting or increased physical activity to make energy available for the body. Glucagon also functions in gluconeogenesis which is the conversion of other nutrient molecules other than carbohydrate, such as amino acids and lactate into glucose to provide energy for the body.

The function of glucagon therefore implies that:

  • A protein rich meal will increase glucagon secretion
  • A carbohydrate rich meal will decrease glucagon secretion since it functions on other food molecules
  • Exercise will increase glucagon secretion
