Answer:
The main difference is motility and composition.
Explanation:
Cilia are structures involved in movement and therefore there's a strong nervous connection with the inside of the cell. Otherwise, microvilli are mainly used to increase absorption and they're also thinner and shorter.
Another great difference is the composition. Cilia are made up of microtubules, while microvilli is made up of microfilaments.
In the same way, cells during development also express specific sets of genes. These patterns of gene expression cause cells to communicate with neighboring cells, resulting in coordinated development into a multicellular organism.
Answer:
Experiments
Explanation:
The ancient Greek philosophers spent more time philosophising and thinking about scientific explanations to phenomena in the natural world.
How ever, they relied solely on reasoning while attempting to explain scientific observations. Contemporarily, science is highly empirical. The scientific process can only be complete when scientific observations are subjects to rigorous experiments in order go determine the actual relationship between variables and provide better explanation for scientific observations.
Hence the ancient Greek philosophers should have used experiments rather than sole reason in proffering scientific explanations to natural phenomena.
Answer:give me brainliest
Explanation:
A combination of the Q wave, R wave and S wave, the “QRS complex” represents ventricular depolarization. Ventricular depolarization occurs in part via an accessory pathway (AP) directly connecting the atrium and ventricle and thus capable of conducting electrical impulses into the ventricle bypassing the AV-His Purkinje conduction system.This term can be confusing, as not all ECG leads contain all three of these waves; yet a “QRS complex” is said to be present regardless.
