How did land whales eventually became aquatic?

Biology
1 answer:
cluponka [151]3 years ago
8 0

Explanation:

To swim, they move their tails up and down, rather than back and forth as fishes do. This is because whales evolved from walking land mammals whose backbones did not naturally bend side to side, but up and down. ... Whales do the same thing as they swim, showing their ancient terrestrial heritage.

Cetaceans are fully aquatic marine mammals belonging to the order Artiodactyla, and branched off from other artiodactyls around 50 mya (million years ago). Cetaceans are thought to have evolved during the Eocene or earlier, sharing a closest common ancestor with hippopotamuses.

Why is protien synthesis different in prokaryotes and eukaryotes?
zhenek [66]
Prokaryotic protein synthesis can be fairly fast because one gene can be transcribed and translated simultaneously. Eukaryotic synthesis is slower, but more precious. They can "check" the mRNA before it is translated into protein.

When in danger, I can’t run from a stranger; But even when I’m in a bad mood, I can make my own food. What kingdom am I?
Anna71 [15]

<u>Answer:</u>

<em>I belong to the kingdom Plantae. </em>

<u>Explanation:</u>

<em>Plantae is one among the five kingdoms in the five kingdom classification. </em>Plants are not mobile organisms unlike organisms of other kingdoms. <em>The roots of plants hold them to the earth and thus they are immobile. </em>

Being immobile, they cannot run away from potential dangers like mobile organisms. But being autotrophs they make their own food by the process of photosynthesis. <em>Heterotrophs depend on autotrophs for food to obtain energy.  </em>
