The actively dividing cells, or meristems, control plant growth. Primary (apical) meristems, the dividing tissue at the tips of the roots, grow longer roots, and secondary meristems, the dividing tissue seen in the cross-sections, grow thicker roots.
I remember back in 10th grade I learned that birds that had beaks that were easier to break the seeds carried those traits to their babies and the whole area had that type of beak since it was necessary to break some seeds. So the beaks that were a disadvantage no longer existed and the beaks that became an advantage passed along to all the other birds.
Side note: if they all had the same beak they could all fight for the same type of seeds and probably have some sort of intense competition but idk if that’s necessary
Answer:
Active transport: movement against a gradient To move substances against a concentration or electrochemical gradient, a cell must use energy. Active transport mechanisms do just this, expending energy (often in the form of ATP) to maintain the proper concentrations of ions and molecules in living cells.
those would be myofibrils
All raw meat contains bacteria that can be harmful to our bodies. Different types of meat have different temperatures to which we have to cook it to kill this bacteria, so we can eat it without getting sick.
