Answer:
No
Explanation:
I do not believe that scientist will ever run out of things to study because there is so much we don't know so the scientists will try figuring it out for maybe a couple years but they might restudy things from the past to help us now.
Answer:NO
Explanation:
EVERYDAY BY DAY SCIENTISTS ARE DISCOVERING THINGS AND NEW IDEALS ARE COMING
Complete question:
Consider these phylogenetic trees. The first tree is based on physical characteristics. The second tree is based on structure, genetics, and evolutionary history. Which can be concluded from a comparison of the two phylogenetic trees?
Answer:
2.Classification can change with new discoveries and evidence.
Explanation:
In phylogenetic trees, two species are more related if they have a recent common ancestor. On the other hand, two species will be less related if their common ancestor is not a recent one and is located far away in the tree.
The phylogenetic tree is composed of,
• Lineages → These are the taxonomic groups of interest placed in the extremes of the lines called branches.
• Nodes → These are the ramification points, which are also known as divergence points. They represent the location of the most recent common ancestor.
• Root → This is the older common ancestor that all lineages share. The first one in the tree.
Two or more lineages are more related to each other if they share a recent common ancestor. This means that they all diverge from the same node.
Two or more lineages are less related to each other if they lack a recent common ancestor. This is, the node from which these lineages diverge is placed far away in the tree.
There are also different phylogenetic relationships between lineages.
• Apomorphies
• Plesiomorphies
• Homoplasy
In the exposed example, we have two trees.
Tree 1 reflects that the three species share a common ancestor that is far away in history. From this common ancestor (the blue point in the image), the duck first diverged. Later in evolution, Platypus diverged, and finally, Opossum diverged. The three species are morphologically well-differentiated from each other.
Tree 2 suggests a common ancestor of the three species (the blue point in the image), placed far away in history. From this common ancestor, the duck first diverged. But later in evolution, there was a second branch that diverged, and later originated Platypus and Opossum. According to the information provided by structure, genetics, and evolutionary history, Platypus and Opossum share a most recent common ancestor (the red point in the image).
Both trees provide equally important information. However, tree 2 is more detailed about evolutionary events because it involves many aspects of the animals´ history. Using one of the trees or the other, or both, will depend on the goals of the experiment.
The conclusion we can get from this comparison is that as long as there are discoveries and scientific advances, there will be a constant influx of information useful to recreate or explain evolution. Classification will keep changing with discoveries and evidence.
Answer
Classification can change with new discoveries and evidence.

I got 100% on the test
Answer: Hydrotropism
Explanation: Hydro means water and tropism means moving in a positive orientation by the organism.The movement of plant in the response to the higher humidity is known as hydrotropism.
The process starts with the root cap movement that sense water and sends signals to the roots for elongation.
Example: plants moving towards higher humidity.
b. Scientists use relative dating to determine the absolute age of a new fossil.
c. Scientists use radioactive isotopes to determine the absolute age of a new fossil.
d. Scientists use index fossils to determine the specific years of age of a new fossil.
The pancreas produces the peptide hormone known as human insulin, which is essential for controlling blood sugar levels. There are two peptide chains in it, joined together by disulfide bonds.
An "A" chain and a "B" chain are the two peptide chains that make up human insulin. The A and B chains' amino acid sequences are arranged as follows:
A Chain (21 amino acids):
GIVEQCCTSICSLYQLENYCN
B Chain (30 amino acids):
FVNQHLCGSHLVEALYLVCGERGFFYTPKT
The 51 amino acids of human insulin make up the entire protein. Human insulin has a molecular mass of around 5808 Da (Daltons).
Dimer: Since human insulin is made up of two peptide chains (A and B chains) connected by disulfide bonds, it is a dimer.
Peptide Chains: The A chain and the B chain are the two peptide chains that make up human insulin.
Location: The beta cells of the pancreatic islets of Langerhans generate and secrete human insulin.
Learn more about amino acids:
Human insulin is a peptide hormone consisting of 51 amino acids across two chains. The primary amino acid sequence of chain A includes Gly, Ile, Val, and others. Insulin, a dimer, circulates in the bloodstream and binds to insulin receptors on cells.
The protein of interest I will elaborate on is human insulin. Insulin is a peptide hormone produced by beta cells in the pancreas. It has a total of 51 amino acids divided into two peptide chains linked by disulfide bridges, Chain A and Chain B. Chain A has 21 amino acids while Chain B has 30.
The primary amino acid sequence of chain A of human insulin starts with: Gly, Ile, Val, Glu, Gln, Cys, Cys, Thr, Ser, Ile, Cys, Ser. The molecular mass of insulin is approximately 5808 Da.
Insulin is a dimer in its storage form but functions as a monomer when it is actively binding to receptors. As it is a hormone, it circulates in the bloodstream and binds to insulin receptors on cells to promote glucose uptake.
