Hemoglobin is the protein inside red blood cells that carries oxygen. Red blood cells also remove carbon dioxide from your body, transporting it to the lungs for you to exhale. Red blood cells are made inside your bones, in the bone marrow. They typically live for about 120 days, and then they die.
Answer:
1. Sympathetic input increases ventricular contractility, thereby increasing stroke volume.
2. Sympathetic input decreases conduction time within the heart, decreasing the delay between atrial and ventricular contractions.
3. Sympathetic input increases the speed of ventricular contraction.
Autosomal traits would show Mendelian inheritance pattern but sex-linked traits would show criss cross inheritance.
Sex-linked trait is often controlled by gene present only on X chromosome, hence no corresponding allele is present on Y chromosome.
