Answer:
B) Identifying the minerals within it
Explanation:
Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date the age of rock layers.
Answer:
option D
Explanation:
When an organism is heterozygous for a particular trait, it means the organism has two different allele for that particular trait. An allele is the alternate for of a gene. For example, using Mendel's pea plants, he studied the height trait having the tall and the short allele for this height trait. Thus, this cn be written as (Tt) where T represent the tall allel and t represent the short allele.
Answer:
1) The genetic changes can lead to a reduction in the capacity of the mice to move glycogen at its branches points and lowers blood glucose levels between meals.
2) Genetic changed can lead to a decrease in the capacity to lower blood glucose due to the knock out of the hexokinase gene leading to elevated levels in the bloodstream.
(c) A knockout of FBPase2 will result in elevated levels of fructose-2,6-bisphosphate in
liver favoring the glycolytic pathway and inhibiting gluconeogenesis by the decrease of fructose 1,6-
bisphosphatase-1 activity
(d) An active FBPase-2 will now favor gluconeogenesis and this inhibits glycolysis. I.e. a decrease in PFK-1 activity while increasing FBPase-1 activity simultaneously.
