Answer:
1. Reducing
2. External
Explanation:
The external urinary sphincter, also called as external urethral sphincter consists of skeletal muscles. During micturition reflex, the micturition center present in the brain serves to inhibit the somatic motor neurons by reducing their action potential. These somatic motor neurons innervate in the external urinary sphincter.
Inhibition of somatic motor neurons of the external urinary sphincter results in relaxation of the sphincter to facilitate the act of urination.
Undergo differentiation
become stem cells
turn on all of the genes found in the nucleus
some cells can undergo cell division
Answer:
The correct answer is (A) gene A is a positive regulator of gene B.
Explanation:
When positive regulation occurs a transcription factor is required to bind at the promoter in order to enable RNA polymerase to start transcription.
RNA means ribonucleic acid and it is a long single-stranded chain of cells that processes protein.
Answer:
1. Binding of insulin to the alpha subunit of the insulin receptor
2. Activation of insulin receptor tyrosine kinase
3. Phosphorylation of IRS proteins
4. Activation of PIP3-dependent protein kinase B (PDK1)
5. Phosphorylation of phosphinositide 3-kinase (PI-3K)
6. Conversion of PIP2 to PIP3
7. Activation of Akt
8. Glut4 receptors transported to cell membrane
Your body cells use oxygen you breath to get energy from the foods you eat. The process is called "Cellular Respiration." This process or function consists of the cell using oxygen to break down sugars in the body. When the cell uses the oxygen to break down sugars, carbon-dioxide is produced and energy is released, thus producing the energy your body needs.
"Hemoglobin" is a protein with Red Blood cells (also referred to as RBC's) that are responsible for the transport of oxygen. The Cardiovascular System consists of the heart and vessels and may also be referred to as the vascular system or the circulatory system. The heart functions as a muscular pump that pushes blood through the vessels to all areas of the body and the vessels function to carry it back to the heart as well. Hence the name "circulatory."
