Yeast cells are eukaryotic. What does this mean? in your own words
Answers
Answer:
Yeast cells are eukaryotic which means that they have a membrane-bound nucleus that holds their genetic information.
Eukaryotic cells also contain membrane-bound organelles such as:
Mitochondria responsible for energy productionRibosomes responsible for protein synthesisCell wall that protects the cell from the environmentThe Golgi apparatus that packages proteinsIt also means that their cellular complexity is different from Prokaryotic organisms which lack membrane-bound structures for example the nucleus. Prokaryotic cells are mostly small and simple and Eukaryotic cells are typically a lot bigger and more complex.

B. RADIATION FROM X-RAYS CAUSES A MUTATION IN BRAIN CELL.
C. A CHEMICAL AND CIGARETTE SMOKE CAUSES A MUTATION IN A LUNG CELL.
D. A SUBSTITUTION IN DNA CODING CAUSES A MUTATION IN A SPERM CELL.
I THINK ITS D. BUT CAN SOMEONE HELP ME !!!!!
Answers
Answer:
yeah
Explanation:
it's obviously D . it's a heritable change because the mutation in the sperm cell is gonna cause a mutation in the zygote
A mutation in the sperm cell will most likely result in heritable change ton the attributes of organisms.
Mutations that happen in vegetative cells such as skin, lung, and brain cells cannot be passed on to future generations.
Heritable mutations are those changes to the DNA sequence of sex cells. Changes elicited by such mutations are passed to future generations because they are germline based.
Sperm cells are sex cells. Thus, changes that occur as a result of mutation to sperm cells are most likely heritable.

What are some benefits of farming for the society/environment?
Answers
Answer:
Pasture and cropland occupy around 50 percent of the Earth's habitable land and provide habitat and food for a multitude of species. When agricultural operations are sustainably managed, they can preserve and restore critical habitats, help protect watersheds, and improve soil health and water quality. in addition to preserving the earth's natural resources, sustainable agriculture benefits the environment through helping maintain soil quality, reducing erosion, and preserving water. Plants and trees in agricultural systems help to retain and add water to underground aquifers. ... Together, they act as an important buffer in the landscape, preventing flooding, reducing water pollution from agricultural runoff and preventing erosion, while providing us with nutritious food at the same time. Farming creates opportunities to lift people out of poverty in developing nations. Over 60 percent of the world's working poor works in agriculture. Farming creates more jobs, beginning with farmers, and continuing with farm equipment makers, food processing plants, transportation, infrastructure and manufacturing.

Answers
The one important difference between savannas and temperate grasslands
is that Temperate grasslands are mostly treeless.
Temperate grasslands have varying types of plants and animals in the
region. They have very few trees and are mainly dominated by grasses.
The temperate grasslands have lesser amount of rainfall than the
savannas.
The Savannas have different types of plants ranging from shrubs to
woody trees. The temperate grasslands have nutrients due to the
formation of organic matter from dead plants leaves and roots and aren't
generally regarded as having nutrient poor soil.

In general, did the simulated mice align with your predictions from the Punnett squares?.
Answers
Research studies are often carried out using mouse. From the study, the simulated mice was said to align with the predictions from the Punnett squares. So the answer is Yes.
The reason why some of the percentages did not exactly match your predicted results because the Mice don't have large litters, so the sample size was not large enough.
If the experiment is to be done again, I can improve upon experimental design by;
Increase the number of mice bred. Examine a different trait within mice. Examine a trait in another species. Test patterns for future generations.A lot of studies is been carried out on the Genetics of the mouse. The early development of inbred lines were studied. The mouse is known to be a good tool to identify the genetic basis of both normal and disease traits.

Read the excerpt from "The Lady Maid's Bell." I had been near a week at Brympton before I saw my master. Word came that he was arriving one afternoon, and a change passed over the whole household. It was plain that nobody loved him below stairs. Mrs. Blinder took uncommon care with the dinner that night, but she snapped at the kitchen-maid in a way quite unusual with her; and Mr. Wace, the butler, a serious, slow-spoken man, went about his duties as if he'd been getting ready for a funeral. He was a great Bible-reader, Mr. Wace was, and had a beautiful assortment of texts at his command; but that day he used such dreadful language that I was about to leave the table, when he assured me it was all out of Isaiah; and I noticed that whenever the master came Mr. Wace took to the prophets. Which best describes a gothic element in the excerpt and the social attitude it reveals? The arrival of Mr. Brympton causes fear, revealing that men are powerful in the world. Mrs. Blinder prepares a dinner well, revealing that cooking is considered the highest art. Mr. Wace reads the Bible, revealing that religion is no longer a respected institution. The servants do not like the master, revealing that having servants is no longer acceptable.
Answers
Answer:
A.) The arrival of Mr.Brympton causes fear,revealing that men are powerful in the world.
Explanation:
This is because after he arrives, the slaves hate him. However, the fact that Mr. Wallace reads a bible doesn't matter because he is more worried that his master is back same with the cook. Therefore, it would be that this particular man is very powerful and has power over these people.
