What is cellular respiration?

Use complete sentences to explain how the mass of carbon is conserved during cellular respiration.

Answers

Answer:

The mechanism by which organisms use oxygen to break down food molecules in order to obtain chemical energy for cell functions is known as cellular respiration. In the absence of oxygen, cells can generate energy by fermenting food, a mechanism known as anaerobic respiration.

Explanation:

- Eijiro <3

It’s the process by which cells obtain energy from glucose sugar by breaking down simple food molecules into usable chemical energy Seeley respiration is different than the trim respiration which is used for breathing. The respiration equation is C6H12O6 + 6O2 -> 6CO2 + 6H2O + energy. Notice the equation is opposite of photosynthesis. Aerobic uses oxygen anaerobic doesn’t use oxygen it doesn’t use enough oxygen so it doesn’t create ATP

Conserving: It’s important to keep our environment safe. It effects both us and animals. One way you can that conserve the environment is by protecting the environment and volunteer in programs that help do so.

Cleaning up: This is very vital to the environment. The amount of trash and litter is insane. Animals on sea or land can eat the trash, thinking that it’s food and can either choke on it and get sick. It also can destroy the plants of the environment, it can even affect humans, like for example a toddler might pick a piece of plastic of the ground and choke on it.

Chiming In.
In order to conserve and protect the environment, we need willing participants that will provide help for the task. Volunteer in beach clean ups, or go to an local park and pick up all the trash. You can also do help without volunteering by just doing the bare minimum, (throwing your trash away in the can, recycle, and encourage those around you to do the same)

In your own words, who were the alchemists? What do you know about them and their work so far?

Answers

Answer:

an alchemist is a person versed in the art of alchemy their goal was to create philosophers stone and discovery of elixir of life

Explanation:

hope it helps❤️

Alchemy is an ancient practice shrouded in mystery and secrecy. Its practitioners mainly sought to turn lead into gold, a quest that has captured the imaginations of people for thousands of years. However, the goals of alchemy went far beyond simply creating some golden nuggets.

Alchemy was rooted in a complex spiritual worldview in which everything around us contains a sort of universal spirit, and metals were believed not only to be alive but also to grow inside the Earth. When a base, or common, metal such as lead was found, it was thought to simply be a spiritually and physically immature form of higher metals such as gold. To the alchemists, metals were not the unique substances that populate the Periodic Table, but instead the same thing in different stages of development or refinement on their way to spiritual perfection.

As James Randi notes in his "Encyclopedia of Claims, Frauds, and Hoaxes of the Occult and Supernatural," "Beginning about the year 100 and reaching its flower in medieval times, alchemy was an art based partly upon experimentation and partly upon magic. Early investigators of natural processes centered their search on a mythical substance they knew as philosopher's stone, which was supposed to possess many valuable attributes such as the power to heal, to prolong life, and to change base metals into precious metal — such as gold." (This "philosopher's stone" was not a literal stone but instead a wax, liquid, or powder that held magical powers.)

Explanation:

Asteroid and Comets:

While asteroids consist of metals and rocky material, comets are made up of ice, dust, rocky materials and organic compounds. When comets get closer to the Sun, they lose material with each orbit because some of their ice melts and vaporizes. Asteroids typically remain solid, even when near the Sun.

Planets and dwarf planets:

The main difference between a dwarf planet and a planet is size. Because they are smaller, dwarf planets lack the gravitational forces needed to pull in and accumulate all of the material found in their orbits.

Inner Planets and Outer Planets

Inner planets are the closest 4 planet to the Sun in the solar system. They are mostly made of rocks(Mercury, Venus, Earth, and Mars.) Outer Planets are the 4 planets that are the most far away from the Sun. They are mostly made up of ice, and gas (Jupiter, Saturn ,Uranus and Neptune.)

Earth and Venus

While Venus and Earth have similar sizes and are solar system neighbors, they have evolved very differently. Venus today lacks oceans, appears to lack plate tectonics, and has a massive carbon dioxide atmosphere that creates a greenhouse effect that makes the surface a hot hell.

It takes the moon 29.5 calendar days to orbit Earth. The moon is currently in the third quarter lunar phase, and it’s November 10th. On approximately what date will the new moon occur?

November 17th b) November 24th c) December 1st d) December 8th

Answers

Answer:

Explanation:

dffffffffffff

1. C; It’s less than a month which means it’s more predictable of it being a full moon. It isn’t D as that’s a month and when that passes, it will be third quarter again; Seeing as the Third quarter is after the full moon.

2. A; Each moon phase is about 7 days, so the transition of the third quarter to new moon would take about 7 days.

Select the characteristics of a hydrogen bond: hydrogen attracted to weakly positive atoms a gravitational force intermolecular force between hydrogen and oxygen, fluorine, or nitrogen an attraction between polar molecules

Answers

Answer:

intermolecular force between hydrogen and oxygen, fluorine, or nitrogen

an attraction between polar molecules

Explanation:

these are the correct answers....

Hydrogen bond is a type of intermolecular force between hydrogen atom and oxygen, fluorine, or nitrogen atoms Thus, the correct option is C.

What is Hydrogen Bonding?

A hydrogen bond is a type of an intermolecular attractive force in which a hydrogen atom is covalently bonded to a small, highly electronegative atoms i.e., nitrogen, oxygen, and fluorine. Hydrogen atom is attracted to a lone pair of electrons on an atom in a neighboring molecule. Hydrogen bonds are very strong compared to other dipole-dipole interactions. However, these bonds are weaker than covalent bonds.

Hydrogen bonds are responsible for the surface tension properties of water. The bonds are also responsible for the relatively high boiling point of water molecules because of strong attractive forces.

Therefore, the correct option is C.
