Passage 1: Excerpt from Will Yellow School Buses Soon Become Rolling Ads?
1 Tight school budgets could soon translate into Missouri school districts’ selling ad space on yellow school buses.
2 Missouri state Rep. T.J. Berry, R-Kearney, says his bill—HB 224—isn’t a cure-all by any stretch. But legalizing ads inside and outside the buses would give school districts one additional way to raise money in these tough times.
3 “Every single school district has had to deal with budget concerns,” Berry said last week. “And generally speaking, the way they have had to deal with those has been cuts or tax increases.”
4 The school bus is something that is already out there and paid for, he said. His bill would permit districts to generate a modest stream of income from their buses.
5 Few question the need for finding additional funds when it comes to educating children, but at least two groups think the school bus exteriors should remain ad-free.There is no such thing as free money,” said Josh Golin, associate director for the Campaign for a Commercial Free Childhood. “There are real costs to this: the price of selling out your students to advertisers.”
7 Students don’t need the first and last message they receive from their schools each day to be advertisements, Golin said. Students boarding a bus are certainly a captive audience.
8 The National Association of State Directors of Pupil Transportation Services opposes advertising on safety grounds. Obscuring the recognizable school-bus yellow exterior with ads and distracting other drivers “present a safety problem around school buses that cannot be ignored,” the group said in its position paper.
9 National studies have shown that anything that diverts a driver’s attention from the road can pose a hazard, opponents say.
10 “And a big yellow bus doesn’t distract?” Berry asked.
11 Several years ago in Indiana, a Department of Education lawyer suggested that allowing advertisements on buses would invite First Amendment challenges by spurned advertisers, the group noted.
What happened as the mass of the sun increased during the formation of the solar system?
Answer:
The Sun and the rest of the solar system formed from a giant, rotating cloud of gas and dust called a solar nebula about 4.5 billion years ago. Most of the material was pulled toward the center to form our Sun, which accounts for 99.8% of the mass of the entire solar system.

The increase in gravitational pull, which caused the surrounding gas and dust to be pulled towards the center of the developing solar system.
What is the Solar system?As the mass of the sun increased during the formation of the solar system, several important changes occurred. One of the most significant changes was the increase in gravitational pull, which caused the surrounding gas and dust to be pulled towards the center of the developing solar system. As a result, the temperature and pressure at the center increased, eventually reaching a point where nuclear fusion began and the sun became a star.
The increase in mass also had an impact on the orbits of the planets. As the gravitational force of the sun increased, it caused the orbits of the planets to become more stable and circular, rather than elliptical or irregular. This stability allowed the planets to maintain their orbits over billions of years, contributing to the long-term stability of the solar system.
In addition, the increase in mass allowed the sun to retain more of the lighter elements, such as hydrogen and helium, which were abundant in the early solar system. This abundance of lighter elements contributed to the formation of the gas giant planets, such as Jupiter and Saturn, which have massive hydrogen and helium atmospheres.

Which of the following is NOT one of the major land biomes? a. tropical rain forest c. temperate grasslands b. temperate savanna d. temperate deciduous forest
Answer:
Temperate Savanna.
Explanation:
Savanna is not temperate, it is also called tropical grasslands, further supporting my answer. It is PART of the kinds of grasslands, So because it is a part, it is not a major Biome.
Temperate savanna is not the major land biomes.
What is Biomes?Some of the electrons in metallic atoms are held there quite loosely. As a result, they frequently lose electrons and generate cations. In contrast, most nonmetallic atoms have a stronger attraction to electrons than do metallic atoms, and as a result, they gain electrons to form anions.
As a result, when two atoms from a metallic and a nonmetallic element unite, the nonmetallic atoms usually tend to take one or more electrons from the metallic atoms and create ions.
One-third of the Earth is covered in forests, which are primarily made up of trees. A large portion of the terrestrial biodiversity of the planet, including insects, birds, and mammals, is found in forests.
Therefore, Temperate savanna is not the major land biomes.

A paramecium is a unicellular organism that lives in pond water. It has a cell structure known as a contractile vacuole that uses energy to pump out water so that the paramecium does not burst. What does this demonstrate?
A.) osmosis
B.) diffusion
C.) homeostasis
D.) cellular respiration
Describe two things that would happen in an ecosystem if there were no unicellular organisms. Explain why something with only one cell can be considered to be an organism.
Unicellular organisms include bacteria, protists, and yeast. For example, a paramecium is a slipper-shaped, unicellular organism found in pond water. It takes in food from the water and digests it in organelles known as food vacuoles. Nutrients from the food travel through the cytoplasm to the surrounding organelles, helping to keep the cell, and thus the organism, functioning. Multicellular organisms are composed of more than one cell, with groups of cells differentiating to take on specialized functions. In humans, cells differentiate early in development to become nerve cells, skin cells, muscle cells, blood cells, and other types of cells. One can easily observe the differences in these cells under a microscope. Their structure is related to their function, meaning each type of cell takes on a particular form in order to best serve its purpose. Nerve cells have appendages called dendrites and axons that connect with other nerve cells to move muscles, send signals to glands, or register sensory stimuli. Outer skin cells form flattened stacks that protect the body from the environment. Muscle cells are slender fibers that bundle together for muscle contraction. The cells of multicellular organisms may also look different according to the organelles needed inside of the cell. For example, muscle cells have more mitochondria than most other cells so that they can readily produce energy for movement; cells of the pancreas need to produce many proteins and have more ribosomes and rough endoplasmic reticula to meet this demand. Although all cells have organelles in common, the number and types of organelles present reveal how the cell functions.

If there were no unicellular organisms available in the ecosystem then there will be no atmospheric nitrogen fixation and no recycling of organic matter into plant usable products.
Unicellular organisms are small single celled organisms that can be observed through microscope but not with naked eye. The unicellular organisms are bacteria, fungi, virus, and protists. If no unicellular organisms are present in the ecosystem then there will be no nitrogen fixation by the soil bacteria like Nostoc, Cyanobacteria, and others. Since, plants cannot utilize atmospheric nitrogen directly so these bacteria convert the atmospheric nitrogen into plant usable form that is ammonia. When no soil bacteria present in the soil ecosystem then the plants will not be able to grow as ammonia is a chief ingredient of many biomolecules in plants. If there will be no unicellular organisms then there will not be any decomposition process of the organic matter and the waste of dead animals, plants, and other living beings will not recycle into plant usable form this will limit plant growth and will also affect the natural cleaning mechanism of ecosystem. Only one cell can be considered an organism if it shows characteristics of an organism like food intake, respiration, reproduction, and growth.Hence, if there were no unicellular organisms available in the ecosystem then there will be no atmospheric nitrogen fixation and no recycling of organic matter into plant usable products.
