I believe its D they decompose wood and other tough materials and then absorb them.
Answer:
Silencer
Explanation:
Silencers are the position and orientation free sequences that are present outside the protein-coding sequence of a gene. Silencers serve as a binding site for some transcriptional regulatory proteins that tend to inhibit gene expression. Binding of these "repressor" proteins to the silencers inhibits the gene expression.
The deletion of silencers from DNA would increase the rate of the gene expression as the inhibitory transcription regulatory proteins do not have binding sites to inhibit the gene expression. Therefore, the deletion of silencer sequences of the beta-globin gene would have caused the increased rate of its expression.
Answer:
2 out of every 5 or 2/5
Explanation:
there are 200 black cats because there are 300 calico there are 500 total so it would be 200/500 or 2/5
• Matthias Schleiden observed that all plants were made of cells; Theodor Schwann observed that all animals were also made of cells; and Rudolf Virchow observed that cells only come from other cells.
• Prokaryotic cells- don’t contain a nucleus or any other membrane-bound organelle.
Eukaryotic cells- contain membrane-bound organelles, including a nucleus.
• Phospholipids make up the basic structure of a cell membrane and are arranged in a double layer called the lipid bilayer.
• Active Transport- moves ions from low concentration to high, using metabolic energy in the form of ATP.
Passive Transport - moves ions from high concentration to low, using no metabolic energy.
