Answer:
Explanation:
Minnesota's hardwood forests developed in the absence of earthworms. Without worms, fallen leaves decompose slowly, creating a spongy layer of organic "duff." This duff layer is the natural growing environment for native woodland wildflowers.

Answer:
False.
Explanation:
Three domains of life are bacteria, eukarya and archaea. The prokaryotic organisms are involved in the bacteria and archaea. Eukaryotic organisms are included in the domain eukarya.
The archaea are more similar to eukarya than bacteria. The cell walls of the archaea are made of glycerol-ether lipids. The phospholipids of archaea are built on a backbone of sn-glycerol-1-phosphate. Archaea lacks the peptidoglycan layer in its cell wall.
Thus, the answer is false.
Beyond size, the main structural differences between plant and animal cells<span> lie in a few additional structures found in </span>plant cells. These structures include: chloroplasts, the cell<span> wall, and vacuoles.</span>
Exons are the DNA fragments that get to be transcripted and translated into proteins. Option b)<u> </u><u>Exons</u> end up being expressed in the protein.
<h3>What are introns and exons?</h3>
Even though more than 70% of the DNA is related to genes, just a part of the genes is translated to proteins. Most genes have DNA segments that are not transcripted or translated intercalated with segments that are translated.
- Introns are non-encoding sequences that produce interruptions in a eukaryotic gene.
- Exons are the encoding sequences. Exons are the nucleotidic sequences that do codify proteins.
Most of the eukaryotic, multicellular genes contain introns in their sequences, intercalated with exons.
Introns are transcripted to mRNA molecules and get excised before translation by a specific mechanism. This occurs before the mRNA leaves the nucleus. The introns are excised and the exons must splice to form a unique molecule. This process is known as splicing.
Exonic sequences are the fragments that are transcripted and translated into proteins.
The correct option is b). Exons end up being expressed in the protein
