What did Neil Armstrong eat when he was on the moon?

While the astronauts had a selection of meals and snacks aboard the Apollo 11 Command Module, the supplies aboard the Lunar Module were more limited. The astronauts could enjoy grape, pineapple-grapefruit and orange drinks as well as freeze-dried coffee. The Lunar Module also contained a snack pantry holding candy bars, dried fruit, ham salad, turkey and bread.\nAll food was shelf-stable, requiring no refrigeration or heating before use. Items like soups and stews came in tubes or pouches, and they were designed to be thick enough not to escape into the spacecraft cabin. Bacon and turkey squar..

What is the smallest unit of evolution?

Evolution acts upon populations, not individuals. Individuals do not evolve in their own lifetime. For natural selection to occur, generations must pass. In general, a trait that proves advantageous for a particular population in a particular environment tends to spread throughout the population as the gene for that trait is passed from parents to offspring. Individuals that lack that advantageous trait are less likely to survive and reproduce. Hence, the gene for that trait becomes increasingly prevalent, and the population as a whole evolves over the course of time.

How big is a proton?

A proton is roughly the same size as a neutron, but it is much larger than its negative counterpart, the electron. In an atom, protons and neutrons stick together to make up the nucleus at the center of the atom. Electrons float around the nucleus in orbits. In total, atoms are comprised of electrons, protons and neutrons. Each atom has a different number of each of these microscopic particles.

What kinds of traits improve an organism's changes of survival?

Being able to see, smell, hear or otherwise sense danger or predators enables the organism to flee or respond in the most effective way of ensuring its survival. Mobility, or the ability of an organism to move, is essential for ensuring an organism’s survival. Mobility allows the organism to find food rather than wait for it and provides the ability to flee from danger. It allows organisms to travel to more hospitable environments during certain seasons of the year and to travel to breeding grounds to mate.\nThe trait of adaptability is perhaps the most important as it allows an organism to ..

How do you convert 55 degrees Fahrenheit to Celsius?

Subtract 32 from the degrees FahrenheitThe first step to converting degrees Fahrenheit into degrees Celsius is to subtract 32 from the degrees Fahrenheit value, expressed as 55 minus 32 is equal to 23.Multiply 23 by 5/9Next, the resulting number from the first step is multiplied by the fraction 5/9. Either use the fraction or the decimal value 0.5555 when performing this calculation. The expression is: 23 multiplied by 0.5555 is 12.78. Find the answerThe result of the conversion formula is 12.78, so 55 degrees Fahrenheit is equal to 12.78 degrees Celsius.

How many endangered animals are there?

Both the Endangered Species Act of the United States and the International Union for Conservation of Nature make provisions for listings of endangered species. As of 2014, the Endangered Species Act recognizes only about 1,500 endangered species, both plants and animals, worldwide. The Endangered Species Act estimates that 13 percent of all vertebrate species worldwide are at risk for endangerment or extinction. The Endangered Species Act uses several factors to determine endangerment of a species. They include the state of the habitat of a particular species, the toll that over-harvesting tak..

What are the different types of acids?

According to BBC Science, strong acids typically have higher concentrations of hydrogen ions than weak acids at the same concentration level. When exposed to water, all acids produce hydrogen ions. Strong acids fully ionize and take the forms of hydrochloric acid, sulfuric acid and nitric acid. Weak acids, in contrast, form mixtures that have higher pH levels than strong acids. Ethanoic acid is a prime example of a weak acid.

How many oxygen atoms are in AL2(CO3)3?

To count the total number of atoms in a chemical formula, multiply each portion in parentheses by the subscript after it. By this method, Al2(CO3)3 is equivalent to Al2C3O9. If there is a coefficient, for example, in a chemical equation that must be balanced, the quantity of each atom is multiplied by this coefficient as well. For example, 2H2O, or two molecules of water, contains a total of four hydrogen and two oxygen atoms.

What is the name for the compound Fe2O3?

Ferric oxide has several practical uses. As a very fine powder, this compound is useful for polishing jewelry. Some manufacturers use ferric oxide as a pigment in cosmetics and other products. Ferric oxide is also used to produce several different alloys, which are mixtures of metals and other elements. This compound has a molecular weight of 159.6882 grams per mole, according to PubChem Compound.

What is an analogy for mitochondria?

ATP is a chemical that is found throughout all the domains of life, from dandelions to amoebas to tuna fish, mushrooms and people. Food is made (as in plants) or eaten (as in animals) and ultimately broken down into ATP to create chemical energy for being alive. The process of creating ATP from food is called the citric acid cycle.\nMitochondria take in nutrients floating in the cytoplasm and break them down within their inner membranes using enzymes specialized for the task. Among the chemicals involved is the familiar citric acid, found in fruits such as oranges and lemons, but here involved..
