In what way does an earthquake provide evidence about the layers of Earth? Use complete sentences to write your answer.
Answers
Answer:
When an earthquake occurs the seismic waves (P and S waves) spread out in all directions through the Earth's interior. Seismic stations located at increasing distances from the earthquake epicenter will record seismic waves that have traveled through increasing depths in the Earth.

Since the beach mice live in the beach (obviously) that is their ecosystem. This means that there are predators that eat the mice on the beach.
Let us assume that the mice in the beach have been isolated from the other deer mice and therefore could not reproduce with them
It comes down to survival of the fittest. The mice with the lightest fur survived because they blended in with their environment and avoided predators, so they reproduced and created more “light coat” offspring. Each generation the mice with the light coats were able to escape predation and reproduce. Therefore it is reasonable that the two mice have different genes that code for their fur colour.
The forest mice need a darker fur to blend in with their environment to avoid predation, so they’re fur stayed darker over the generations for the same reasons listed above ( vice versa of course )
Summarize Darwin's theory of natural selection using the Galapagos tortoises or finches as an example.
Answers
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.

Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake.

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.

Explanation:
Every compound can be represented by a chemical formula. A chemical formula is the set of symbols showing the elements that make up a compound and their proportions. Water’s chemical formula is H_2 2 O. That means a molecule of water contains two atoms of hydrogen and one atom of oxygen chemically bonded. A molecule is a group of two or more atoms bonded together. Molecules can range in size from two to thousands of atoms. A molecule of a compound is the smallest unit of that compound. Every molecule of water has all the physical and chemical properties of water. That’s because every molecule of water is made of the same elements in the same proportions: two hydrogen atoms and one oxygen! Which of the following is a true statement?
A
Every molecule of the same compound will have different properties.
B
Every molecule of a compound has the same proportion of elements.
C
Molecules can be physically separated into smaller units of a compound.
D
Molecules cannot be represented by chemical formulae.
Answers
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.
