- Q: 1. Does God exist? The complexity of our planet points to a deliberate Designer who not only created our universe, but sustains it today.Many examples showing God’s design could be given, possibly with no end. But here are a few:The Earth…its size is perfect. The Earth’s size and corresponding gravity holds a thin layer of mostly nitrogen and oxygen gases, only extending about 50 miles above the Earth’s surface. If Earth were smaller, an atmosphere would be impossible, like the planet Mercury. If Earth were larger, its atmosphere would contain free hydrogen, like Jupiter.3 Earth is the only known planet equipped with an atmosphere of the right mixture of gases to sustain plant, animal and human life.The Earth is located the right distance from the sun. Consider the temperature swings we encounter, roughly -30 degrees to +120 degrees. If the Earth were any further away from the sun, we would all freeze. Any closer and we would burn up. Even a fractional variance in the Earth’s position to the sun would make life on Earth impossible. The Earth remains this perfect distance from the sun while it rotates around the sun at a speed of nearly 67,000 mph. It is also rotating on its axis, allowing the entire surface of the Earth to be properly warmed and cooled every day.And our moon is the perfect size and distance from the Earth for its gravitational pull. The moon creates important ocean tides and movement so ocean waters do not stagnate, and yet our massive oceans are restrained from spilling over across the continents.4Water…colorless, odorless and without taste, and yet no living thing can survive without it. Plants, animals and human beings consist mostly of water (about two-thirds of the human body is water). You’ll see why the characteristics of water are uniquely suited to life:It has an unusually high boiling point and freezing point. Water allows us to live in an environment of fluctuating temperature changes, while keeping our bodies a steady 98.6 degrees.Water is a universal solvent. This property of water means that thousands of chemicals, minerals and nutrients can be carried throughout our bodies and into the smallest blood vessels.5Water is also chemically neutral. Without affecting the makeup of the substances it carries, water enables food, medicines and minerals to be absorbed and used by the body.Water has a unique surface tension. Water in plants can therefore flow upward against gravity, bringing life-giving water and nutrients to the top of even the tallest trees.Water freezes from the top down and floats, so fish can live in the winter.Ninety-seven percent of the Earth’s water is in the oceans. But on our Earth, there is a system designed which removes salt from the water and then distributes that water throughout the globe. Evaporation takes the ocean waters, leaving the salt, and forms clouds which are easily moved by the wind to disperse water over the land, for vegetation, animals and people. It is a system of purification and supply that sustains life on this planet, a system of recycled and reused water.6The human brain…simultaneously processes an amazing amount of information. Your brain takes in all the colors and objects you see, the temperature around you, the pressure of your feet against the floor, the sounds around you, the dryness of your mouth, even the texture of your keyboard. Your brain holds and processes all your emotions, thoughts and memories. At the same time your brain keeps track of the ongoing functions of your body like your breathing pattern, eyelid movement, hunger and movement of the muscles in your hands.The human brain processes more than a million messages a second.7 Your brain weighs the importance of all this data, filtering out the relatively unimportant. This screening function is what allows you to focus and operate effectively in your world. The brain functions differently than other organs. There is an intelligence to it, the ability to reason, to produce feelings, to dream and plan, to take action, and relate to other people.The eye…can distinguish among seven million colors. It has automatic focusing and handles an astounding 1.5 million messages — simultaneously.8 Evolution focuses on mutations and changes from and within existing organisms. Yet evolution alone does not fully explain the initial source of the eye or the brain — the start of living organisms from nonliving matter.2. Does God exist? The universe had a start – what caused it?Scientists are convinced that our universe began with one enormous explosion of energy and light, which we now call the Big Bang. This was the singular start to everything that exists: the beginning of the universe, the start of space, and even the initial start of time itself.Astrophysicist Robert Jastrow, a self-described agnostic, stated, “The seed of everything that has happened in the Universe was planted in that first instant; every st

- A: Let’s just assume all of your statements here are correct*. So what?All you’ve managed to show is that for life, to exist as it currently does, water needed to have existed.Life on this, or any other planet, is not necessary. Further, you haven’t shown any reason to think a deity had to do it. Further still, you haven’t shown any reason the deity you believe in had to do it, and not, like, Thor.

- A: 1. Metabolism is defined as the chemical reactions designed to maintain life.2. Organic compounds by definition are those that contain carbon-hydrogen bonds. Since the question also tells you that it is one of the two most common in the human body, and the two most common elements are oxygen and carbon, we know that the answer is carbon.3. Cells get energy by breaking apart chemical bonds in materials. While they can use DNA and Proteins, the energy is much easier to acquire by breaking apart Carbohydrates, which is why carbohydrates are the primary source of fuel.4. A polymer is a macromolecule that repeats units over and over again. I have trouble answering this because not all carbohydrates are polymers. Glucose, for example, does not repeat; however, a polysaccharide such as starch would count as a polymer since it is a repeating structure. Proteins by definition are polymers, and an amino acid is also a polymer. Because two of the answers ~are~ polymers, and the last can be a polymer, I’d say “all of the above”.5. Carbohydrates6. Lipids are traditionally fats, though they often serve other functions. Butter and Vegetable Oil.7. Enzymes: They specifically catalyze chemical reactions by lowering the energy of activation.8. potatoes, rice, and bread.9. A nucleic acid consists of a chain of nucleotides.10. water is the ultimate dissolver.11. They use beams of electrons to see very small objects.12. Proteins are made of amino acids, so names because they have an amine group and a carboxylic acid group.13. Fatty acids14. A chloroplast is what allows plant cells to produce their own food by making organic materials out of inorganic materials. Animals are not able to make their own food, so the answer is D.15. Mitochondria are the major energy producers in a cell, creating ATP through cellular respiration.16. The cell membrane prevents many substances from entering or leaving the cell.17. Vacuoles are the big storers and movers. They’re particularly big in plant cells to store water, which also allows plants to have their rigidity. When plants are low on water, their vacuoles don’t hold as much water so the cells crumple, causing wilting.18. Prokaryotes do not have mitochondria; in fact, the commonly accepted theory is that mitochondria were once prokaryotes that bonded with an early ancestor of eukaryotes.19. As mentioned above, chloroplasts create food. That food is sugar.20. Ribosomes are basically protein factories.21. The golgi apparatus, although it doesn’t always ship them to the cell membrane. It sends them wherever they need to go for the most part.22. The nucleus is the “brain” of the cell. It is where DNA is turned to RNA which becomes the proteins that allow the cell to do its job, so without the nucleus there would be no new proteins to signal cellular activity.23. Lysosomes break things apart, whether that be food, foreign contaminants, or worn out cell parts.24. Cell Wall. Note that many prokaryotes and fungi have these as well, but animals do not.25. Endoplasmic Reticulum26. The Cytoskeleton.27. Eukaryote (“Eu” means “True” and “Karyote” means “Nucleus”)
