DNA's genetic information is copied to form ___ RNA, which then delivers it to the ___ where protein synthesis occurs.

Answers

Answer:

DNA's genetic information is copied to form mRNA, which then delivers it to the ribosome where protein synthesis occurs.

Explanation:

During transcription, RNA polymerase uses a single-stranded DNA template to synthesize a complementary strand of RNA. The mRNA then travels from the nucleus to the cytoplasm where ribosomes are found. Ribosomes are structures that are responsible for making proteins.

Ethan began making a model to show the processes which resulted in the formation of oceans
Which of the following would be the next step in the process?
Crust is broken down
Earths crust moves
Earths plates meet
Sea floor spreading

Answers

It has to be either A or B bc the other 2 were already used, I would go with B) earth crust moves

The next step in the process is sea floor spreading. The correct option is D.

What is sea floor spreading?

Tectonic plates, which are huge chunks of the lithosphere of the Earth, split apart from one another during the geologic process of seafloor spreading.

The oceanic basin is the result of sea floor spreading.

The ocean crust and its basins are formed when the sea floor spreads and separates after the basin has been filled with water.

All of these result from various plate interactions within the planet.

New ocean floors are created by volcanic activity at spreading centers at divergent borders after the crust has developed and accumulated water.

The production of fresh crust occurs close to the margin, and subsequent crusts push against and away from it. Ocean basins are created by the development of new ocean floors.

Thus, the correct option is D.

In maize, yellow kernel color is dominant to white, and wrinkled kernel shape is dominant to the smooth form. Considering both of these traits jointly in self- fertilized dihybrids, the progeny appeared in the following numbers: 193 white, genes assort independently? Support your conclusion using appropriate statistical analysis. wrinkled; 184 yellow smooth; 556 yellow, wrinkled: 61 white smooth

Answers

Answer:

yellow, wrinkled are high in population whereas white smooth is lower in population.

Explanation:

Due to self-fertilized dihybrids, the offspring are yellow wrinkled, hybrid and white smooth. 556 yellow, wrinkled are high in population because of the dominant allele while on the other hand, 61 white smooth are obtained and less in number due to recessive nature that comes very little in the population. 184 yellow smooth and 193 white, wrinkled are the hybrid offspring that has both different characteristics from their parents.
