So, if your DNA specifies that a protein should be made using the amino acid valine, then lysine, and finally serine, then those amino acids would be assembled in that sequence.
Answer:
False
Nuclear power reactors do not release direct carbon dioxide emissions but require a lot of energy.
Coal however releases a large amount of greenhouse gases
Answer:
- First outgroup → Ray-Finned Fishes
- Second outgroup → Sharks
Explanation:
The outgroup is the most distant taxonomic group that shares no traits or characters with the lineages of interest, which compose the ingroup. You can compare the outgroup with the ingroup to determine the evolutive relationship and which characters are primitive or derived.
Even though the outgroup shares a common ancestor with the ingroup, this is placed far away in evolution, making the outgroup to be the taxonomic group less related to the other lineages. The lineages in the ingroup share another common ancestor that is more recent in history.
To select the outgroup, you need to focus on what you are interested in. There might be several outgroups, but you should choose the one that is more related or closer to the ingroups. This selection is important because you need to make comparisons to understand the evolution of specific traits.
In the exposed example, we need to focus on animals that have four limbs. Then, we might assume that the ingroup is composed of Amphibians Crocodiles Dinosaurs. Sharks and Ray-Finned Fish do not have four limbs, so they might be considered outgroups.
From these two outgroups, sharks have a cartilaginous skeleton, while Ray-Finned Fishes have a bony skeleton. This fact makes ray-finned fishes more related to the ingroup than the sharks. So,
- First outgroup → Ray-Finned Fishes
- Second outgroup → Sharks
Answer;
-Lipid soluble molecules
Explanation;
The principal components of the plasma membrane are lipids (phospholipids and cholesterol), proteins, and carbohydrate groups that are attached to some of the lipids and proteins.
The arrangement of proteins in the plasma membrane involves the hydrophobic and hydrophilic regions found on the surfaces of the proteins.
-Hydrophobic regions associate with the hydrophobic interior of the plasma membrane and hydrophilic regions extend past the surface of the membrane into either the inside of the cell or the outer. Like the interior plasma membrane, lipid soluble molecules are also hydrophobic, they do not dissolve in water but in organic solvents.
