Explanation: The heart, blood and blood vessels work together to service the cells of the body. Using the network of arteries, veins and capillaries, blood carries carbon dioxide to the lungs (for exhalation) and picks up oxygen. From the small intestine, the blood gathers food nutrients and delivers them to every cell.
The heart pumps the blood, this way, the circulatory system work at the organ level. The correct option is 1.
What is organ level of organization?When two or more tissues collaborate for a specific function, this is referred to as organ level organisation.
The circulatory system transports oxygen, nutrients, and hormones to the body's tissues while also removing waste products such as carbon dioxide.
The heart circulates blood throughout the body: The heart is a muscular organ that circulates blood throughout the body.
The heart has four chambers that work together to pump blood: the right atrium, right ventricle, left atrium, and left ventricle.
The right atrium receives deoxygenated blood from the body, which is then pumped to the lungs for oxygenation by the right ventricle.
The left atrium receives oxygenated blood from the lungs and pumps it to the body via the left ventricle.
Thus, the correct option is 1.

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 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.

5. Diagram below shows four moon phases observed during July. O First quarter July 8 Moon Last quarter July 24 New Moon July 16 July 31 On which date would the next New Moon occur?
Answers
Answer:
August 6th
Explanation:
The next new moon will occur on 15 august. The time period between two new moons is 29.5, which is called a lunatic or synodic month.
What is the moon cycle?The moon orbits the Earth once every 29.5 days, which is known as the moon cycle. Each month, as the Moon progresses through its cycle, which includes a New Moon and a Full Moon, it exhibits eight successive phases. A lunar eclipse occurs when Earth passes in front of the Sun and the Moon, obstructing the Moon's exposure to sunlight. The lunar surface is entirely or partially hidden by Earth's shadow.
Every 27.3 days (a sidereal month), the Moon completes one orbit around Earth, but until it reaches the point in its orbit where the Sun is at the same relative position, the Moon has not yet completed a synodic cycle. This is due to Earth's orbital motion around the Sun.
Hence, the next moon will occur on 15 august.

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.
