Answer:
C.) use a systematic method to name, organize, and show relationships among species.
Explanation:
Answer:
Smooth muscle fibers have an oblong shape, much like a football. They’re also thousands of times shorter than skeletal muscle fibers. Similar to skeletal muscles, cardiac muscles are striated. They’re only found in the heart. Cardiac muscle fibers have some unique features.
Explanation:
Answer:
1. coevolution
2. abiogenesis
3. Endosymbiont Theory
4. It's estimated that over 99 percent of the species that have existed on Earth at some point in time are extinct today.
5. Coevolution implies that the evolution of one species is dependent on and works in relation to the evolution of another species. This may cause positive or negative impacts and could be beneficial to both organisms or only to one.
6. This theory states that the first building block of life that allowed for reproduction of organisms was the development of self-replicating RNA. This hasn't been able to be fully demonstrated in any science experiment but is based on the idea that there are RNAs that can catalyze biochemical reactions on their own without proteins.
7. This process points to the development of structures through the envelopment of smaller cells that perform specific functions. This is how eukaryotic cells evolved from prokaryotic cells.
8. This experiment was important because it showed that, in the right primordial soup, organic compounds could develop from inorganic compounds.

The answer is the apoplast, the symplast, and the transmembrane pathway.
1. The apoplast pathway occurs through cell walls and space between cells. So, water does not cross any cell membrane as it travels this pathway.
2. The symplast pathway occurs through the continuum of cytoplasm. So, water travels through plasmodesmata which connect cells.
3. The transmembrane pathway occurs across cell membranes. So, water enters the cell on one side of the membrane and exits on the other.
