Answer: Extraneous Variable
Explanation: Extraneous Variable. When we conduct experiments there are other variables that can affect our results, if we do not control them. These other variables are called extraneous or confounding variables.
1. The heme of hemoglobin releases the iron. The heme then converted into biliverdin, which is converted into bilirubin.
2. Conjugated bilirubin is excreted as is then part of the bile into the small intestine. Bacteria of the intestine break down the bilirubin.
3. Some bilirubin derivatives converted into which is contribute to the color of feces.
4. Other biliurbin derivatives are reabsorbed from the intestine into the blood. These derivatives are excreted from the kidneys and contribute to the color of urine.
5. The globin chains of hemoglobin are broken down to individual amino acids and are metabolized or used to build new proteins.
6. Blood transports free bilirubin to the liver.
7. Blood transports iron in combination with transferrin to various tissues for storage or to the red bone marrow where it is used in the production of new hemoglobin.
8. Hemoglobin is broken down by macrophages into heme and globin chains.
The correct answer is Neutron
Explanation:
As shown in the diagram the sub-particles in atoms are electrons, neutrons, and protons. From these, the two types of particles that are in the nucleus or center of the atom are neutrons and protons. Moreover, neutrons differ from protons because these are neutral or are not charged. According to this, the uncharged particles in atoms are neutrons.
Moreover, the number of neutrons can be calculated by subtracting the atomic number (number of protons) to the mass number (number of atoms and protons). For example, if in an atom the mass number is 12 (protons and neutrons)and the atomic number is 6 (number of protons), the neutrons are 6 (12 - 6 = 6). According to this, the correct answer is the neutron.
A gene that has been associated with a language disorder in humans and is quite different in apes is the FOXP2 gene.
