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.
Hippopotamuses live in Africa’s rivers and lakes. They’re herbivores and coexist with other herbivores and carnivores. Which action could lead to a decrease in the number of hippos?
Answers
Answer:
If any of the other carnivores are predator they might eat the hippos. If the other herbivores population incresses there food supply may drop. If there is a drought there habitat will be in danger. Pouchers are also a threat to this animal.
Explanation:
The Hippopotamuses lives in the river and lakes of Africa. They are herbivores and co exist with other herbivores and carnivores.
There can be two possible reasons for the decrease in the number of hippos.
The carnivores lion and hyena can eat the hippo(young hippos) which will reduce the number of hippos.
The other reason could be reduction in the number of plants that hippos eat.

Which of the following statements is true? Which of the following statements is true? No archaea are capable of using CO2CO2 to oxidize H2H2, releasing methane. Prokaryotes have low levels of genetic diversity. Archaea and bacteria have identical membrane lipids. The cell walls of archaea lack peptidoglycan.
Answers
Answer:
The correct answer is - The cell walls of archaea lack peptidoglycan.
Explanation:
Archaea are the prokaryotes that are different from bacteria in various ways but the most important differences are the membrane lipids and the major component of the cell wall that lacks peptidoglycan found in the cell wall of bacteria.
These prokaryotes are able to use carbon dioxide to oxidize hydrogen, releasing methane. Archaea-like prokaryotes have a high level or complex genetic diversity.

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
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.
