Multiple soil horizons make up a soil profile. Soil horizons are distinguishable regions of soil. They run parallel to the surface and have different characteristics. The soil horizons include the A horizon, E horizon, B horizon and C horizons.
The soil profile is a vertical cross section showing these horizons.
meteorite impact or a movement (earthquake) underwater.
Answer:
The correct option is A. mRNA.
Explanation:
mRNA is a single stranded RNA molecule, complementary to one of the DNA strands of a gene. Also known as messenger RNA, mRNA is synthesized in the nucleus and then exported to the cytoplasm, where the translation machinery (the machinery that actually makes the proteins), binds to the mRNA molecules and reads in them the code to produce a protein specific. During protein synthesis, an organelle called a ribosome moves along the mRNA, reads its sequence of bases, and uses the genetic code to translate each triplet of three bases or codon, into its corresponding amino acid.
Answer:
50% will be white (Ww) and 50% will be black (ww)
Explanation:
Here's what the punnett square should look like.
In order for the black ram to have its coloring it would need to have 2 recessive genes (ww). The female is heterozygous, meaning she carries both genes (Ww) but only exhibits the dominant gene, in this case white fur (though they can pass the recessive gene on to their children). Simply filling out the punnett squares shows the outcome of the offspring.
