Answer:
In humans, the major precursors from which glucose can be synthesized from are:
1. glycerol from triacylglycerols
2. glucogenic amino acids from protein.
3. Oxaloacetate formed from CO2
4. Pyruvate foem pyruvate carboxykinase
All there's are routes through which the body obtains glucose to replenish body glucose levels
The are formed by cells building carbohydrates polymers, they use energy
to form glycosidic linkages..the bonds between monosaccarides...which
is made by joining two specific monomers, glucose and fructose.
D) The AV valves are supported by chordae tendineae so that they do not blow back up into the atria during ventricular contraction.
Answer:
The correct answer would be option D.
Explanation:
True breeding is a breeding procedure in which the parents would always produce their progeny with the same phenotype characters as the parents carry. This means for every trait these parents are homozygous so their offspring must show a similar phenotype.
In this case, all cattle are true-breeding which means they homozygous alleles show the progeny will also show similar traits which are short stature with brown hides and short horns.
Thus, the correct answer is option D.
