Which of the following is an adaptation to permafrost? a. retention of dead leaves
b. dense hairs
c. shallow roots
d. waxy leaves
The correct answer is option c. "shallow roots".
Some plants had developed shallow roots as an adaptation to permafrost. The artic plants have shallow roots because the permafrost does not allow the plants to push its roots deep down under the frozen topsoil looking for liquid water. Most arctic plants have a very short growing period of time since the liquid water above the frozen topsoil lasts liquid only from 50 to 90 days per year.
it is C. Shallow roots, for those using edginuity just took the test

Do all bonds have the same strength? Explain (and list the different types and describe them)
A high school girl who is self-conscious about her appearance has been fasting for several days to fit into a dress she intentionally bought a size too small for a school dance. Which of her organs/tissues is producing the glucose that is being synthesized through gluconeogenesis?
Answer: The liver
Gluconeogenesis is a process by which glucose molecules are produced de Novo (from non carbohydrates precursors such as lactate, glycogenic amino acids, and glycerol).
Only the liver can replenish blood glucose through glycogenolysis and gluconeogenesis.
During prolonged fasting or starvation the protein catabolism is speeded up to provide precursors (glucogenic amino acids) for gluconeogenesis.
Gluconeogenesis occurs mainly in the liver because one of the key enzyme glucose-6-phosphatase needed for glucose synthesis is only present in the liver.
