What do most plants need to grow?
What do most plants need to grow? Plants, like all living organisms, have basic needs: a source of nutrition (food), water, space in which to live, air, and optimal temperatures in order to grow and reproduce. For most plants, these needs are summarized as light, air, water, and nutrients (known by the acronym LAWN). How […]
What is a policy how is it different from a law quizlet?
What is a policy how is it different from a law quizlet? How does it differ from a law? A policy is a formalized body of expectations that describe acceptable and unacceptable employee behaviors in the workplace. The difference between a policy and a law is that ignorance of a policy is an acceptable defense. […]
What is the coldest dwarf planet?
What is the coldest dwarf planet? However, since 2006, Pluto is no longer considered to be a planet because specialists have realized that it is much smaller than we imagined, giving it the status of a dwarf planet. Today, two planets can claim the title of “coldest planet in the solar system”: Neptune and Uranus. […]
What are genetic characteristics?
What are genetic characteristics? Genetic characteristics are the traits you inherit from your parents. They include your physical structure, your biochemistry and, to some extent, your behavior. The environment also plays a substantial role in how your genetic characteristics, especially the behavioral ones, are expressed. What are some examples of genetic characteristics? For example, one […]

Is carbon a homonuclear diatomic? Homonuclear diatomic molecules include hydrogen (H2), oxygen (O2), nitrogen (N2) and all of the halogens. The element carbon is known to have a number of homonuclear molecules, including diamond and graphite. Which element does not exist as a diatomic molecule? Carbon Why Sulphur does not exist as diatomic in nature? […]
Is gravity created by mass?
Is gravity created by mass? So, the closer objects are to each other, the stronger their gravitational pull is. Earth’s gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body. That’s what gives you weight. Does rotation affect gravity? While the spinning of the […]
What comes first population or community?
What comes first population or community? Individuals make up a population; populations make up a species; multiple species and their interactions make up a community; and multiple species and their interactions make up ecosystems when you include the abiotic factors. This is the hierarchy of ecology. What defines the number of organisms living in a […]

Your heart pumps blood through a complex network of blood vessels. When your blood circulates through your digestive system, for example, it picks up nutrients your body absorbed from your […]
What forms of energy changes take place when a gun is fired?
What forms of energy changes take place when a gun is fired? A bullet stores chemical potential energy in its gunpowder. When the bullet is fired, this chemical energy is converted into kinetic energy and heat. Why does the Dart have a little bit of gravitational potential energy before it is fired? However, the dart […]
