Answer: Incomplete dominance
Explanation:
In incomplete dominance, both alleles are expressed but have become blended giving rise to a new trait with one also been more noticed than the other although both are expressed. For instance a red flower and a white flower are crossed, giving rise to a pink flower. As compared to codominance, both alleles are equally expressed and are equally dominant. For example, a white college crossed with a black hen giving rise to a black and white (checkered) chick.
Answer:
B- environmental factors do most of the “selecting.”
Explanation:
Natural selection is the environment that the organism lives in, and the process which that organism changes by.
Artificial selection is when humans intervene and create an organism that isn't suited for their specific environment, but rather for the humans own liking.
Think of breeding dogs to be smaller, or more fluffy and adorable. These are not traits to help them survive in where they original environment was.
Answer:
B. the action of microRNAs that block translation of specific mRNA molecule
C. the action of RNA–protein complexes that degrade the regulatory proteins responsible for initiating transcription.
Explanation:
RNA interference occurs what RNA prevent the translation of some gene this is done by neutralizing target mRNA molecule. It suppresses the effects of some desires genes through its action.
MicroRNA and small interfering RNA (miRNA and siRNA) are the major RNA that controls interference. siRNA and miRNA prevent translation by directing some enzmes complexes to denature the mRNA molecule needed for translation. They intiate post transcriptional splicing.
RNA interference is found in eukaryote and some animals and its initiated by enzyme Dicer that inhibits translation by degrading the enzymes action.
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: Nitrogen is so vital because it is a major component of chlorophyll, the compound by which plants use sunlight energy to produce sugars from water and carbon dioxide (i.e., photosynthesis). It is also a major component of amino acids, the building blocks of proteins.
