Answer:

D) There are two major subunits, each with multiple proteins.

Explanation:

The ribosome is a complex structure made of RNA and proteins. Both prokaryotic and eukaryotic ribosomes have two subunits: small and large subunits. Each of these subunits is made of specific types of ribosomal RNAs (rRNA) and a number of different proteins.

For example, the 30S subunit of <em>E. coli</em> ribosome has 21 different proteins while its 50S subunit is made of 33 different types of proteins along with rRNA.

Likewise, the 40S subunit of a eukaryotic ribosome is made of 33 proteins while its 60S subunit has 47 proteins. The eukaryotic ribosome contains a total of 80 different proteins.

<h2><u>Answer:</u></h2>

Amid the Ordovician Period, the outside of the earth was drastically unique in relation to it is today. About all life on earth was in the seas. The main land life was as exceptionally crude plants extremely close to the water line of the coasts, presumably greeneries and green growth and were of a non-vascular nature.

The Ordovician Period started with a noteworthy eradication called the Cambrian– Ordovician annihilation occasion, about 485.4 Mya (million years prior). It went on for around 42 million years and finished with the Ordovician– Silurian elimination occasions, about 443.8 Mya (ICS, 2004) which cleared out 60% of marine genera.

The timeframe that occurred 488 to 443 million years back. Amid the Ordovician time frame, some portion of the Paleozoic time, a rich assortment of marine life thrived in the tremendous oceans and the primary crude plants started to show up ashore—before the second biggest mass annihilation ever finished the period.
