As I am not to familiar cell plant to the looks precise the leaf shape on option A. Please dear correct me if I’m incorrect!
Answer:
Mid-ocean ridges are found in the sea floor at divergent boundaries because both plates are moving away from each other creating the opening for the lava to sleep up. Mid-ocean ridges are where sea floor spreading occur by lava seeping up to the surface of the opening and cooling therefore forming new ground and pushing older layers of ground further away.
Hey there! Darwin's finches had different beak sizes and shapes because of natural selection. Over time, the more desirable traits become more dominant and distinct. These beaks were best fit for the type of food the bird ate. Smaller-beaked birds usually have a seed diet, and larger-beaked birds usually eat large nuts or small creatures like worms and bugs. Hope this helps!
Answer:
1) A double Helix with complementary bases in the middle. The backbone is made of sugar and phosphates. The middle is bases
2) To hold the genetic info for the cell
3) To bring the genetic info from the nucleus to the ribosomes as DNA can't leave the nucleus
4) To bring amino acids to the ribosomes to help build a protein
5) A chain of amino acids held together by peptide bonds
6) Ribosomes
7) Because those are the bases that are complementary in DNA so they must be equal
8) It could lead to a mutation as it would cause the mRNA to code for a different amino acid and thus a different protein will be made
9) DNA is the blueprint for mRNA which will travel to the ribosomes and code for specific amino acids which will eventually build a protein
B) The Earth's crust is pulled apart creating deep folds and then pushed together generating steep scarps to create fault-block mountains
