Well, both subatomic particles of protons and neutrons contribute to the mass of the atom, and thus I believe that the correct response would be D. Protons and neutrons are located in the nucleus of the atom and both are responsible for the mass, atomic mass of the atom.
Answer:
Hox genes are thus a subset of the homeobox transcription factor genes. In many animals, the organization of the Hox genes in the chromosome is the same as the order of their expression along the anterior-posterior axis of the developing animal, and are thus said to display colinearity.
Explanation:
Hox genes, a subset of homeobox genes, are a group of related genes that specify regions of the body plan of an embryo along the head-tail axis of animals. Hox proteins encode and specify the characteristics of 'position', ensuring that the correct structures form in the correct places of the body.
Chromosomes are thread-like structures present in the nucleus, which carries genetic information from one generation to another. They play a vital role in cell division, heredity, variation, mutation, repair and regeneration.
I believe that the amount of carbon stored in organisms decreases as you move up the food chain. This is because carbon constitutes the biomass of an organism which decreases as you move upward the food chain. Each link in a food chain is known as a trophic level. Trophic levels represent a feeding step in the transfer of energy and matter in an ecosystem. Biomass is the amount of organic matter comprising a group of organisms in a habitat. As you move up a food chain, both available energy and biomass decrease. Energy is transferred upwards but is diminished with each transfer from one trophic level to the next.
