Answer:
The suitable words for fill in the blanks will be -
- embryo
- flippers
- disappear
- off
- genetic
Explanation:
Examining a dolphin embryo highlights its evolutionary history. Early in dolphin development, both fore and hind limb buds form. While the forelimb buds continue to develop into flippers, the hind limb buds disappear. The genes that are normally active in the hind limb buds of four-limbed animals are turned off. A genetic change leading to the silencing of a trait during development may have been an important milestone in cetacean evolution.

Answer:
D. Nucleic acids attach to the bases in the DNA.
Explanation:
Transcription begins when an enzyme called RNA polymerase is added to the DNA template and begins a new chain a new chain to produce complementary RNA. During the RNA synthesis transcription takes place, then the cap and tail is added and then splicing occurs. RNA polymerase moves from the 3 'end to the template strand creating the RNA-DNA double helix or similar the base sequences. This makes a chain with each sugar by the set of bonds called phosphodiaster linkage. Then, the enzyme unwind the DNA and begins the synthesis of RNA. Therefore, D. Nucleic acids attach to the bases in the DNA.
<h3>Food chain</h3>
A food chain is a chain of different animal species that are dependent on the next as a source of food. If one source dies, then the chain starts to break.
<h3>Food webs</h3>
Food webs are a system off overlapping food chains. Basically meaning, many food chains combined together.
<h3>Pyramid Model</h3>
A pyramid model includes the following:
- Primary Producers
- Primary Consumers
- Secondary Consumers
- Tertiary Consumers
