Answer: The answer is b!
Explanation:
B. Every molecule of a compound has the same proportion of elements.
What is a chemical compound?A chemical compound is a substance made up of two or more different elements that are chemically bonded together. The elements in a chemical compound are present in a specific ratio, and the properties of the compound are determined by the properties of its constituent elements and their arrangement.
Examples of chemical compounds include water (H2O), table salt (NaCl), and carbon dioxide (CO2). The chemical formula of a compound represents the types and number of atoms present in a single molecule of the compound. In the case of water, the chemical formula is H2O, indicating that it is made up of two hydrogen atoms and one oxygen atom.

The pictures show the Arctic ice cap in 1979 and 2003.
Do the pictures provide evidence for global warming? Explain.
Answer:
Yes because it show how the ice caps have gottin smaller due to global warming
Explanation:
Answer:
Changes in the amount of sea ice can disrupt normal ocean circulation, thereby leading to changes in global climate. Even a small increase in temperature can lead to greater warming over time, making the polar regions the most sensitive areas to climate change on Earth

Our Earth includes a variety of precious natural resources that include sunlight, water, fossil fuels, and forests. Some resources are stored in different forms, which can be processed to obtain useful products, such as petroleum, minerals, or metals. In terms of energy resources, there are two types of natural resources that are used to generate energy: renewable resources, such as water, sunlight, and wind; and nonrenewable resources, such as such as coal, natural gas, or crude oil. The nonrenewable energy sources are widely used around the world. When fossil fuels are burned for energy, carbon dioxide (CO2) is released into the environment. Carbon dioxide is one of the greenhouse gases in the atmosphere that helps to keep the planet warm, as it traps the radiation coming from the Sun. Too much carbon dioxide in the atmosphere can retain high amounts of thermal energy and cause the temperature to rise, which can have devastating effects on the environment. In the last century, the level of atmospheric carbon has increased at an alarming rate.
The graph shows the increase in the concentration of carbon dioxide in the atmosphere since 1900.
QUESTION: Before the eighteenth century, coal was used by humans in many places on Earth for cooking and heating. In the eighteenth century, after the industrial revolution began, fossil fuels like coal were increasingly used to generate power and energy. Today, many manufacturers and nearly all forms of modern transportation depend on these fossil fuels. What effect has this human dependence on fossil fuels had on the world's climate? How has technology contributed to this effect?
Answer: They lead to increased levels of carbon dioxide and other greenhouse gases in the atmosphere which causes the greenhouse effect.
Renewable resource: Sunlight, water, wind,
Norenewable: coal, natural gas, oil
Since fossil fuels are located all over the world, it makes it much easier to create electricity from them than things that are hard to come by.

Which choice is involved in both sexual and asexual reproduction?
spores
eggs
sperm
seeds
The correct answer is:
A.(spores)
I took the test, hope this helps!
The choice that is involved in both sexual and asexual reproduction is the spore that is presented in the first option, as the spore can be released by a wide variety of species, such as fungi, mosses, algae, etc.
What is the significance of the spores?These are found in fungi, mosses, algae, and other organisms and can be released when needed, as they are reproductive cells important for the reproduction and survival of these organisms, such as fungi spores that aid in reproduction and survival in harsh environmental conditions. While most spores serve the same purpose, some spores indicate the air quality in the ecosystem.
Hence, the choice that is involved in both sexual and asexual reproduction is the spore that is presented in the first option, as the spore can be released by a wide variety of species, such as fungi, mosses, algae, etc.

Summarize Darwin's theory of natural selection using the Galapagos tortoises or finches as an example.
Answer:
However, the Galapagos finches helped Darwin solidify his idea of natural selection. The favorable adaptations of Darwin's Finches' beaks were selected for over generations until they all branched out to make new species. These birds, although nearly identical in all other ways to mainland finches, had different beaks.
Explanation:
Darwin's theory states that advantageous traits increase survival and reproduction. Galapagos tortoises and finches have adapted to their environments.
What is Darwin's theory of natural selection?Darwin's theory of natural selection is a fundamental principle in evolutionary biology. It states that the traits that provide an advantage to individuals within a population increase the likelihood of survival and reproduction. The process involves four key components: variation, heredity, selection, and time.
Within a population, there is genetic variation, meaning that individuals have different traits. Some traits may be advantageous, such as a thicker coat to survive colder temperatures or a longer beak to access food. Individuals with advantageous traits are more likely to survive and reproduce, passing their traits onto their offspring.
Over time, the frequency of advantageous traits increases within the population, leading to evolution. Natural selection is the mechanism that drives this process, allowing species to adapt and thrive in their environments.

Scientists studied the evolution of horses. They concluded that horses evolved with the emergence of grasslands and an increase of predators. The digits of their early Eocene ancestor evolved into hooves. The diet changed from foliage to grasses. The molar teeth developed and became stronger. Which statements are supported by this evidence?
The digits of the horses’ feet underwent modifications, enabling them to run faster from predators.
The molars of the horses underwent changes so they could chew meat.
The emergence of grasslands over time led to the development of strong molar teeth in horses.
The digits were modified to enable the horses to graze better on hard, rocky surfaces.
Molars became bigger to fit into the jaw structure of modern horses.
