A 30-year old woman was diagnosed with breast cancer. Which of the following processes that we learned
about today would be helpful to her in treating her cancer, and why?
Selective breeding, because she could be sure her children have no risk whatsoever of also getting breast
cancer.
Gene therapy, because it could actively target the cancer cells in her body as a treatment.
Artificial selection, because it could change her DNA so that she is not prone to breast cancer.
The genetic code is said to be universal. Which of the following lines of evidence would best support this idea?
Data that indicate that the genetic code changes frequently.
Data that are inconclusive about the nature of.
the genetic code.
Data that indicate that some organisms use one or more alternate codes.
Data that indicate that the genetic code is the same in all organisms tested so far.
Answer:
hi here is your answer....
Explanation:
Data that indicate that the genetic code is the same in all organisms tested so far.
becuase,
The genetic code is nearly universal, and the arrangement of the codons in the standard codon table is highly non-random. The three main concepts on the origin and evolution of the code are the stereochemical theory, according to which codon assignments are dictated by physico-chemical affinity between amino acids and the cognate codons (anticodons); the coevolution theory, which posits that the code structure coevolved with amino acid biosynthesis pathways; and the error minimization theory under which selection to minimize the adverse effect of point mutations and translation errors was the principal factor of the code’s evolution.

Which statement about these cells is correct?
a.About 20 percent of the cells are dividing.
b. Most of the cells are undergoing meiosis.
c. Most of the cells will never undergo mitosis
d. About 80 percent of the cells are dividing.
About 80 percent of the cells are dividing because of the perfect structure of the cell.
What is cell division?Cell division is the process by which cells multiply that includes nuclear and cytoplasmic division. Meiosis and mitosis are their types.
So we can conclude that about 80 percent of the cells are dividing because of the perfect structure of the cell.

How does the heliocentric model of planetary motion explain a star's path across the night sky?
The sky is fixed and rotates around Earth.
Earth moves along its orbit daily to follow the stars.
The rotation of Earth makes objects in the sky appear to move.
Each star creates a different amount of light, imitating movement.
Answer:
The Rotation of earth makes objects in the sky appear to move
The heliocentric model of planetary motion explains a star's path across the night sky by The rotation of the earth makes objects in the sky appear to move; this is in Option C, as this is one of the best concepts on the planetarium models.
What is the significance of the planetary model?The planetary model is very significant, as the heliocentric model, proposed by Nicolaus Copernicus, explains that the sun is at the center of the solar system and shows that the planets, including Earth, revolve around the sun. This heliocentric model provided a more accurate explanation of the movements of the planets and paved the way for future research.
Hence, the heliocentric model of planetary motion explains a star's path across the night sky by The rotation of the earth makes objects in the sky appear to move; this is in Option C, as this is one of the best concepts on the planetarium models.

Two plates moving towards each other are called convergent plates. Which
structures are likely to form at a convergent plate boundary?
A:rift valley
B:wave erosion
C:mountains
D:river canyons
Mountains are formed when two convergent plates move towards each other. Therefore, option C is correct.
What are convergent pates?A convergent plate boundary is a type of tectonic plate boundary where two tectonic plates are moving toward each other. As the plates move, they can collide, resulting in the formation of various geological features and processes, such as mountain ranges, volcanic eruptions, and earthquakes.
Convergent plate boundaries are one of the three main types of plate boundaries, along with divergent and transform plate boundaries. They are important in shaping the Earth's surface and are associated with some of the most spectacular geological features on the planet.
Thus, mountains are formed when two convergent plates move toward each other. Therefore, option C is correct.
