Describe the role of Cyanobacteria in charging Earth's early atmosphere

1 answer:

7 0

Cyanobacteria were very simple organisms and performed were an role in changing Earth's early atmosphere. They carried out photosynthesis to produce the materials they needed to grow. In this process, they release Oxygen which is needed to sustain life on Earth for Humans and other organisms.

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.

Answer:

The difference between Prokaryotic cell and Eukaryotic cell are;

$\begin{array}{lll}&\underline {\text {Prokaryotic}}& \underline {\text {Eukaryotic}}\\ \\ \text {Nuclear \ membrane \ and \ nucleus} & \text {No \ true \ nucleus \ or} & \text {Has \ a \ true \ nucleus} \\& \text {nuclear \ membrane} & \text {nucleoli \ and \ nuclear \ membrane}\\\\ \text {Membrane \ bound \ cell \ organelle} & \text {None &Present} \\\\ \text {Chromosome \ number \ and \ shape} & \text {One} & \text {Several, more \ than \ one} \end{array}$

Explanation:

Prokaryotic cells

The plasma membranes surround prokaryotic cells, however, within their cytoplasm, there are no organelles bound to the membrane and there is no nucleus in the prokaryotic cell which differentiates it from the eukaryotic cells

Eukaryotic cells

Eukaryotic cells also have plasma membranes, ribosomes and cytoplasm. Eukaryotic cells also have membrane-bound nucleus, membrane bound organelles, such as chloroplast, mitochondria, endoplasmic reticulum, and Golgi apparatus which together differentiates it from a prokaryotic cell
