Answer: B (Color blindness)
Explanation:
Typical red-green color blindness in human patients is caused by mutations on genes located in the X chromosome. These mutations act in a recessive manner. Since females have two X chromosomes, the presence of a mutation in a single one of them does not normally result in color blindness. Males, in contrast, have a single X chromosome and therefore the presence of a mutation is likely to cause the disease.
About the other options: Down‘s syndrome is a numerical chromosomal anomaly, not related to sex. Human blood type is a codominant trait. Finally, tail length in dogs is a polygenic trait not amenable to classic Mendelian analysis.
Answer:
Proteins
Explanation:
Proteins are macromolecules composed of amino acids that perform multiple and varied functions in the body. Proteins that act as chemical messengers are present in the form of hormones, ligands, neurotransmitters, regulatory proteins and enzymes.
Genes code for proteins that in turn control all life processes. The differences we witness in individuals such as weight, height, skin color, intelligence etc are all due to our unique genetic code and a unique combination of proteins that these genes encode. Furthermore, the levels to which our genetic code is expressed is also regulated at the molecular level by proteins.
Answer:
carbon, hydrogen, and oxygen.
Explanation:
Atomic number is the number of protons of an atom. And, given that the atoms are electrically neutral and the charge of one proton is equal to the charge of one electron, the number of electrons is equal to the number of protons. So the neutral atom of sodium has 11 protons and 11 electrons. But, the sodium ion (Na+) has one positive charge, that means that it has lost one negative charge or one electron. Then, the sodium ion (Na+) has 11 - 1 = 10 electrons. <span>Then, the answer is that there are 10 electrons in a sodium ion.
hope this helps :3</span>
