some evidences that support evolution are: anatomy, molecular biology, biogeography, fossils, & direct observation. Genes, which are passed from parent to kid during reproduction, express themselves in these traits.
Evolution is the gradual change in the hereditary characteristics of biological populations over many generations. Genetic recombination and mutation are the usual causes of variation within a population. Genetic drift and natural selection, two evolutionary processes that might lead to particular traits becoming more or less dominant in a population, are likely to occur in this variation. This is how evolution works. Heritable traits emerge over multiple generations in response to shifting evolutionary factors that determine whether a trait is prevalent or rare within a population.

With industrialized food production, for every one unit of energy put on the table in the United States, how many units of nonrenewable fossil fuel energy are required to produce it
In the United States, industrialized food production requires approximately 10 units of nonrenewable fossil fuel energy to produce 1 unit of energy put on the table.
This is because industrialized food production involves the use of heavy machinery, transportation of food from the farm to the distribution center, and the use of fertilizers, pesticides, and other chemicals to produce crops. All of these activities require energy which is typically sourced from nonrenewable fossil fuel sources.
Additionally, food production also requires energy for processing and packaging, which further increases the amount of energy required to produce 1 unit of energy put on the table. In conclusion, industrialized food production requires approximately 10 units of nonrenewable fossil fuel energy for every 1 unit of energy put on the table in the United States.

What general information do we need to research further to investigate the origin of life on Earth?
The fossil record is the information we need to research to investigate the origin of life on Earth.
How do we know the origin of life on Earth?The earliest evidence of life on Earth comes from fossils that are discovered in Western Australia which is about 3. 5 billion years ago. These fossils are the structures called stromatolites which are formed by the growth of a layer of single-celled microbes such as cyanobacteria.
The major source to know the history of life on earth is fossil records. Fossils are the remains of organisms that are present centuries ago. They form when an organism dies and is burry in dirt and is solidified by minerals.

What is the summary of Mendel's principles?
Gregor Mendel discovered the basic laws of heredity through the study of peas. He concluded that genes come in pairs and are inherited as separate entities, one from each parent. Mendel traced the segregation of parental genes and their appearance in offspring as dominant or recessive traits.
Mendel's four postulates and laws of heredity are: (1) the principle of pair factor, (2) the principle of dominance, (3) the law of germline segregation or purity (Mendel's first law of inheritance) and (4) the law of independent selection (Mendel's second law of inheritance).
Mendel generalized the results of his pea experiment into his three principles that explain the genetic basis of diploid organisms. they are: the principle of segregation, the principle of dominance, and the principle of independent assortment.

5. Describe the metabolic pathways in the monarch butterfly that take advantage of milkweed nectar to convert it into an energy currency.
A) Include details about the three phases of cellular respiration as they relate to sugar metabolism.
B) Where (or how) would sucrose enter the pathways?
Milkweed nectar is rich in a sugar, which is called sucrose. This sugar is a disaccharide, made of glucose and fructose. Sugar is broken down into glucose and fructose in the body, using an enzyme called invertase.
The three phases of cellular respiration are as:
Glycolysis is the process by which glucose is converted into energy. In glycolysis, two ATP molecules are made per glucose molecule. Two NADH molecules are also made. Aerobic organisms, such as monarch butterflies, can further process sugars. In the mitochondria, one CO₂ molecule is removed from the sugar, and one NADH is produced.The Kreb cycle is a series of eight enzymatic reactions that produce energy in the form of ATP. In the Kreb cycle, acetyl-CoA is completely oxidized to produce carbon dioxide. This process is aided by the production of NADH, FADH₂, and a molecule of GTP. Oxaloacetate is regenerated to continue the cycle.Oxidative phosphorylation is the process that generates a proton gradient across the inner mitochondrial membrane. This gradient is used by the V ETC complex to generate energy. The V ETC complex is located in the inner mitochondrial membrane, and as protons flow back and forth through the complex, it catalyzes the phosphorylation of ADP to produce ATP.Learn more about cellular respiration https://brainly.com/question/14158795

How are traits passed from generation to generation? Explain how dominant and recessive alleles interact to determine the expression of traits.
Answer:
Genes come in different varieties, called alleles. Somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism. ... However, an allele that is hidden, or not expressed by an organism, can still be passed on to that organism's offspring and expressed in a later generation.
The traits are passed from generation to generation through genes. The process is called heredity.
What is the passing of traits?Heredity refers to the specific ways by which features or traits are passed down through generations via genes. Genes contain the instructions for producing certain proteins, which are responsible for an individual's unique characteristics.
Alleles are distinct variations of genes. Somatic cells contain two alleles for each gene, one from each parent of an organism.
An allele that is hidden or not expressed by an organism, on the other hand, can be passed on to that organism's descendants and expressed in a subsequent generation.

Claim 1: The debris that shaped the Great Plains originated from the igneous material of the Rocky Mountains. (correct)
Claim 2: The magma that produced the Rocky Mountains originated from the Great Plains' rocks. (incorrect)
Great Plains vs Rocky MountainsThe Great Plains were formed by sediment from the Rocky Mountains being transported and deposited by rivers and other geological processes. The sedimentary rock that makes up the Great Plains includes materials such as sand, silt, and clay that were worn down from the uplifted Rocky Mountains and carried eastward by streams and rivers.
The Rocky Mountains were formed by tectonic activity that caused the Earth's crust to uplift and create the mountain range. The mountains are primarily composed of igneous and metamorphic rock that formed deep within the Earth's crust, rather than from the sedimentary rock of the Great Plains.
There is no evidence that supports claim 2, the magma that formed the Rocky Mountains did not come from the rock of the Great Plains.

But there is worse than that. We had thought that Snowball's rebellion was caused simply by his vanity and ambition. But we were wrong, comrades. Do you know what the real reason was? Snowball was in league with Jones from the very start! He was Jones's secret agent all the time. It has all been proved by documents which he left behind him and which we have only just discovered. To my mind this explains a great deal, comrades. Did we not see for ourselves how he attempted—fortunately without success—to get us defeated and destroyed at the Battle of the Cowshed?"
