The atomic number is given in the table along with the group and period they belong to, hence Lithium has the same number of energy levels as Beryllium, and Magnesium has the same number of energy levels as Sodium.
What is atomic number?Atomic number can be defined as the number of protons or the positive charges that are present in the nucleus of an atom.
In the data given here in the table, it can be inferred that:
The number of energy levels, or shells, of electrons in an atom is determined by its position in the periodic table. Atoms in the same row or period of the periodic table have the same number of energy levels, while atoms in the same column or group have similar chemical and physical properties.
Hence, both lithium and beryllium have one energy level or shell of electrons and both magnesium and sodium have three energy levels or shells of electrons.

1) Use the following situation and tables to choose the correct answer.
Randomly sampled students from two high schools were asked what color the district should paint the new stadium. The results are presented in the following tables:
Stadium Color - North Valley High
Color: Survey Results:
silver 30
blue 54
teal 36
Stadium Color - South Hills High
Color: Survey Results:
silver 78
blue 24
teal 18
Make an inference comparing which color each of the two high school populations should choose for the stadium, based upon a qualitative comparison of the sampled data.
A.) North Valley High should choose silver to give the minority of the students who selected silver a win in the selection process. South Hills High should choose teal because a minority of their sampled students selected the color teal than other colors.
B.) North Valley High should choose blue because more of the sampled students selected the color blue compared to the other colors in the survey. South Hills High should choose silver because more of the sampled students selected the color silver than other colors.
C.) North Valley High should choose teal because that color was selected between the other two colors and would appeal to a broader base of students. South Hills High should choose blue in order to appeal to a broader base if its students.
Answers
North Valley High should select blue because more of the sampled students picked the color blue compared to the other colors in the survey. South Hills High should select silver because more of the sampled students picked the color silver than other colors.
This is the correct inference based on the given data. The survey results show that blue was the most popular color among the North Valley High students, and silver was the most popular color among the South Hills High students. Therefore, it would make sense for each high school to choose the color that was most popular among their respective student populations.

Answers
Peter and Rosemary Grant spent years on the Galápagos Islands studying changes in finch populations.
Peter and Rosemary Grant spent years on the Galápagos Islands studying changes in finch populations. Their research focused on observing and analyzing the variations in the populations of finches, which are a group of closely related bird species found in the Galápagos archipelago.The Grants' study was inspired by Charles Darwin's observations of finch diversity during his visit to the Galápagos Islands, which played a significant role in developing his theory of natural selection. The Grants aimed to investigate how natural selection and environmental factors influenced the evolution of finches and their adaptation to different habitats within the islands.Through meticulous fieldwork, the Grants collected data on various traits of finches, such as beak size and shape, body size, and plumage coloration. They observed how these characteristics changed over time in response to factors like food availability, competition, and climatic variations.By studying the finch populations, the Grants were able to provide empirical evidence supporting Darwin's theory of natural selection and gain insights into the mechanisms driving evolutionary changes in response to environmental pressures. Their research significantly contributed to our understanding of evolution and the role of natural selection in shaping species diversity.For more such question on Galápagos Islands

ASAP!!!A scientist designed an experiment to test where a plant's matter came from. She
measured the starting mass of a willow tree, the soil, and the container. After five
years, she repeated the measurements and observed that the tree gained 74 kg (164
lbs) but the soil had not changed much at all (only lost 57 g, approximately 0.12 lbs).
1. Use evidence, from the results, to explain that the idea that the mass of a tree
comes from the soil, is incorrect. 2 points
2. Why is it incorrect to say that the tree's mass comes from sunlight? 1 point
3. If the mass of the tree does not come from the soil or sunlight, explain the trees
increase in mass. 2 points
Answers
Explanation:
The fact that the soil did not change significantly after five years, while the tree gained 74 kg, suggests that the tree's mass did not come from the soil alone. If the tree had gained all its mass from the soil, the soil would have lost an equivalent amount of mass, which did not occur. Therefore, this evidence suggests that the mass of a tree does not come solely from the soil.
While sunlight is necessary for photosynthesis, which allows the tree to produce glucose, the mass of a tree does not come directly from sunlight. Rather, the tree uses the glucose produced during photosynthesis to build its own tissues, such as leaves, branches, and roots. Therefore, while sunlight is necessary for the tree to grow, it is not the source of the tree's mass.
The tree's increase in mass is primarily due to the process of photosynthesis. During photosynthesis, the tree uses energy from sunlight to convert carbon dioxide and water into glucose, which it then uses to build new tissues. Additionally, the tree may have also taken up nutrients, such as nitrogen and phosphorus, from the soil, which it incorporated into its tissues. However, it's important to note that the majority of the tree's mass comes from the carbon that it takes up during photosynthesis, rather than the nutrients in the soil.

Out of the organisms listed, the one that is likely to have 10% of the energy passed on is the buzzard. Therefore, option (A) is correct.
What is second law of thermodynamics?In an ecosystem, only about 10% of the energy available at one trophic level is passed on to the next trophic level. This is due to the second law of thermodynamics, which states that energy is lost as it moves through a system.
Out of the organisms listed, the one that is likely to have 10% of the energy passed on is the buzzard (option A). Buzzards are predators that feed on a variety of small animals, including mice, foxes, and ladybirds.
