A researcher attempts to use a segment of ribosomal RNA as a molecular clock to calculate the date of the last common ancestor of two species. He finds that the two species diverged from a common ancestor 150 million years ago. These particular species have abundant fossil records that strongly suggest that these species diverged 100 million years ago. Which of the following answer choices best describes a reason for the discrepancy in the date of the last common ancestor of these species?

A. Ribosomal RNA is not a reliable molecular clock and should not be used for dating.
B. The neutral mutation rate used in calculating the last common ancestor date may not have been accurate.
C. It is highly likely that the two organisms did not share a common ancestor, so the results are invalid.
D. A large portion of the ribosomal RNA is not vital to survival, so it is not likely to be well preserved.

Answers

Answer:

B

Explanation:

It is B because the mutation rate should not have been accurate if it showes that they diverged 150 million years ago. But the abundant fossil records show that it diverged 100 million years ago.

What is molecular docking?In structural molecular biology and computer-assisted drug design, molecular docking is an important technique. The purpose of ligand-protein docking is to anticipate a ligand's most common binding mode with a protein having a known three-dimensional structure.What is dating? Carbon dating is used to determine the age of ancient material such as an archaeological or paleontological specimen .

A molecular clock estimates how long it has been since similar species separated from a common ancestor based on DNA sequences (or the amino acid sequence of proteins encoded by DNA).

Hence, the correct option is A.

Predict how a loss of function mutation in the p53 gene is most likely to affect the cell cycle in response to DNA damage. Justify your predictions.

Answers

Answer:

The cell cycle of cell multiplication is regulated by three types of genes, the regulatory genes that control mutations, the generic promoters of cell replication, and genes that inhibit cell replication.

The balance between these three types of gene group are what result in a good multiplication of cells without mutations or neoplastic developments.

The p53 gene is one of the genes that is considered as the guardians of the genome, since it is in charge of corroborating and regulating mutated cells, in this way it inhibits their progression in the cell cycle by putting a stop to not replicate defective genes or genes with alterations.

Explanation:

The p53 gene is one of the most altered genes seen in malignant neoplasms, since by altering our guardian of the genome many mutations overlook and more carcinogenic potential will have neoplastic tissue.

In the three groups of genes that we write, all three have a fundamental roll in the cell cycle, but in order to trigger malignant neoplasms, it is necessary that there be a continuous series of gene mutations in these three groups, it is not enough with the mutation of a single gen.

Volcanic outgassing may be defined as an eruption that releases a gas that was dissolved, trapped, frozen, or absorbed in some material.

Volcanic eruption transfers various gases from the interior of the Earth to the atmosphere leading to outgassing which includes water vapor, carbon dioxide, and sulfur.

Given the following phylogenetic tree, which evolutionary event occurred most recently?

A.) development of different forms of symmetry.

B.) development of tissues.

C.) each of these traits evolved at the same time.

D.) protostome and deuterostome development.

Answers

Answer:

Option-D

Explanation:

A phylogenetic tree is a diagrammatic representation which is constructed in to show the common ancestors at the base of the tree and the branches represent the new species.

The phylogenetic tree which is constructed based on the traits evolved during evolution is known as a cladogram. In the given question, the cladogram represents the evolution of various groups of the organism from a common ancestor based on the traits evolved.

The trait which was evolved earlier is present at the base like the development of tissues while the most common trait is present at the top which is the development of deuterostome and protostome.

Thus, Option-D is the correct answer.

State reason(s) why ash should or should not be used in making compost

Answers

Answer:

Fireplace ashes for compost can be used to help maintain the neutral condition of the compost. It can also add nutrients to the soil. Decomposing materials in the compost pile can become somewhat acidic and wood ash can help offset this, as it's more alkaline in nature.  But Adding too much ash to the pile can be detrimental to the makeup of the compost because of its alkalinity. Ashes tend to raise the soil pH, so you shouldn't use it directly on plants, especially acid-loving ones like rhododendrons, azaleas, and blueberries. Also, in high amounts, wood ash can inhibit plant growth by restricting nutrients, like iron.
