Explanation:
<em>Each sporangium is a capsule that contains spores. They are usually aggregated into clusters called sori. The position and arrangement of the sporangia are very important for the identification of ferns. Fronds that have sporangia on their underside are fertile, and those that don't are sterile Ferns don't have seeds; they have spores. The spores are usually on the underside of the fronds. To reproduce, the fern releases the spores into the air. The spores don't grow into new ferns. </em>
Answer:
Plant cells and animal cells are both eukaryotic hence, they have many similar organelles. Common organelles are:
Cell membrane: the structure that separates a cell from exterior environment.
Nucleus: structure where hereditary material is present.
Ribosome: structure where proteins are made.
Endoplasmic Reticulum: associate in protein production
Golgi complex: structure where proteins are modified and packaged.
Vacuole: acts as a storage house for a cell
Cytoplasm: fluid in which all the organelles float.
An estuary. <span>Estuaries are partially enclosed bodies of water along coastlines where fresh water and salt water meet and mix. They act as a transition zone between oceans and continents.</span>
Answer:
C. could not provide a mechanism for moving continents
Explanation:
Without the discovery of magnetic reversals recorded on the ocean floor, scientists could not provide a mechanism for moving continents.
Magnetic reversals are responsible for geological shifts and depend on the distribution of tectonic plates that causes movements of continents.
Asymmetric movement of tectonic plates leads to movement of continents and the degree of asymmetry varies with the same rythm of the magnetic reversal rate.
Hence, discovery of magnetic reversals are important to identify the mechanism for moving continents.
