Answer:
Pleiotropy
Explanation:
Pleiotropy is a genetic condition in which a single gene conditions the expression of multiple phenotype. There are different types of pleiotropy depending on the underlining mechanism
- <em>gene pleiotropy</em>
- <em>developmental pleiotropy</em>
- <em>selectional pleiotropy</em>
- <em>antagonistic pleiotropy </em>
<em>Phenylketonuria is a disease characterized by increased level of amino acid phenylalanine in the blood. It caused by mutation to the gene responsible for breaking down phenylalanine in the blood. Elevated level of phenylalanine causes other issues such as mental problems, urine coloration and reduction in skin pigmentation. This is a clear case of pleiotropy.</em>
Answer:
Undifferentiated inner cell mass
Explanation:
Human embryo has two types of cells in its initial stage, trophoblast and inner cell mass. Trophoblast forms the placenta and inner cell mass form the entire human body. Inner cell mass are pluripotent in nature i.e. they can give rise to any body part under right conditions.
Embryonic stem cells are derived from the inner cell mass. They are derived from pre implantation embryo since after implantation the inner cell mass begins to differentiate. Embryonic stem cells can replicate indefinitely without differentiating. They can give rise to all the three germ layers: ectoderm, mesoderm and endoderm. They can treat a number of disorders like genetic disorders, Parkinson's, spinal cord injury, cancers etc.
The function of the digestive system is to C. To break down food into nutrients.
I think its b or d so do some googling or ask other places
Answer:
The correct answer is NAD+
Explanation:
Glycolysis is the process that occurs in almost all the cells. It occurs in the cytoplasm in both prokaryotes and eukaryotes. In glycolysis partial oxidation of glucose takes place step wise and one glucose molecule gets convert into 2 pyruvate.
The molecule that helps in the partial oxidation of glucose is NAD+. NAD+ is an electron carrier that harvest energy in a series of gradual step from glucose in the form of electrons and gets reduced into NADH.
Then this NADH is used to feed electrons in the ETC during oxidative phosphorylation to make ATP and get regenerated into NAD+. So the correct answer is NAD+.
