what are two roles of bacteria in a nitrogen cycle
Answer:Nitrogen-fixing bacteria convert free nitrogen gas into nitrogen compounds. ... Bacterias that are decomposers recycle nitrogen compounds in the soil by breaking down animal wastes and dead plants and animals. 3. Other bacteria break down nitrogen compounds and release free nitrogen back into the air.
Explanation:
"The nitrogen fixing and bacteria of decay" is the two major role of bacteria in nitrogen cycle."
What is nitrogen fixing?Nitrogen fixing can be define as the process in which It is possible to see nitrogen converting to nitrate.
What is bacteria of decay?Bacteria of decay can be define as the process in which it is possible to see nitrogen waste converting to ammonia.
What is nitrogen?Nitrogen can be referred as element which is kept in boron family in the periodic table.
Therefore, the two role of bacteria in a nitrogen cycle is bacteria of decay and nitrogen fixing.

What is a way to make magnets?
Heating
Pressure
Freezing
Answer:
Heating is the answer
Explanation:
I took the quiz and i know its a late response
Freezing is a way to make magnets from ferromagnetic substance.
What is Curie temperature?Curie point, also known as Curie Temperature, is the temperature at which the magnetic characteristics of some magnetic materials abruptly change. Remnant magnetism manifests in rocks and minerals below the Curie point, which for magnetite, a common magnetic mineral, is approximately 570 °C (1,060 °F).
In some magnetic materials, atoms that act as small magnets spontaneously align themselves below the Curie point, which for iron is 770 °C (1,418 °F). Because the atomic magnets in each microscopic region (domain) of ferromagnetic materials, such as pure iron, are aligned in the same direction, their magnetic fields reinforce one another.

Which of the following is not true about both scientific laws and scientific theories?
Answer:
In general, a scientific law is the description of an observed phenomenon. It doesn't explain why the phenomenon exists or what causes it. The explanation of a phenomenon is called a scientific theory. It is a misconception that theories turn into laws with enough research

I need help with question ii) Calculate the speed of these radio waves.
I don't know if I started it right.... I need help plss!!!
Answer:
Speed = Wavelength x Wave Frequency. In this equation, wavelength is measured in meters and frequency is measured in hertz (Hz), or number of waves per second. Therefore, wave speed is given in meters per second, which is the SI unit for speed.

Which of the following is an example of a valid experiment?Adding Minutes to different types of soda and recording/comparing the reaction height.Asking your friends what kind of candy they like and recording the responses.Building a baking soda volcano
Asking your friends what kind of candy they like and recording the responses.
recording answers are a valid experiment. but at the same time adding minutes to different types of soda and recording is another great idea.
Statement A is correct. Adding Minutes to different types of soda and recording/comparing the reaction height is an example of a valid experiment.
What is an experiment?An experiment is a technique used to prove or disprove a theory, or to test the efficacy or probability of something that has never been done before.
Experiments reveal cause-and-effect relationships by illustrating what happens when a specific component is changed. Experiments have a wide range of goals and scales,
but they always rely on a repeatable technique and rational interpretation of the outcomes. Natural experimental research is also available.

Give three examples of properties of elements
Answer: Atomic number, Atomic Mass, Ionic radius
Explanation:
The three examples of properties of elements are Atomic Number, Melting Point, and Electronegativity are the properties of the element.
Atomic Number: The atomic number of an element is the number of protons found in the nucleus of an atom of that element. Each element has a unique atomic number.
Melting Point: The melting point of an element is the temperature at which it transitions from a solid state to a liquid state. Different elements have different melting points, which can vary widely.
Electronegativity: Electronegativity is a measure of an element's ability to attract electrons toward itself in a chemical bond. It is an important property in determining the nature of chemical bonding and the reactivity of elements. Elements with high electronegativity tend to attract electrons strongly.
Other properties include atomic mass, density, boiling point, reactivity, and many more, which contribute to the diverse behavior and characteristics of elements in the periodic table.

What are the characteristics of bones? (list 7)
What role do joints play?
What are the two types of joints?
What are ligaments?
Answer:
1) The human skeleton performs six major functions: support, movement, protection, production of blood cells, storage of minerals, and endocrine regulation. protection of internal organs
2) Joints are where two bones meet. They make the skeleton flexible — without them, movement would be impossible. Joints allow our bodies to move in many ways.
3)A joint is a point where two or more bones meet. There are three main types of joints; Fibrous (immovable), Cartilaginous (partially moveable) and the Synovial (freely moveable) joint
4)A ligament is a fibrous connective tissue which attaches bone to bone, and usually serves to hold structures together and keep them stable.

Energy can't be created or destroyed - Law of Conservation of Energy.
If this is true, where does the mechanical energy go when skateboarding? Eventually the skateboarder will slow down and stop if she doesn't add more mechanical energy by pushing. Choose the most correct statement below.
Energy isn't conserved and actually gets used up.
Mechanical Energy converts into potential energy and then she stops.
Mechanical Energy gets converted into thermal energy through friction.
explain your answer
Answer: Mechanical Energy gets converted into thermal energy through friction
Explanation: when the skateboard is rubbing against whatever it’s rolling on it creates friction which slows down the skateboard, the mechanical energy is then converted into thermal energy. If you’ve ever touched the bottom of a wheel after going fast it typically feels a little warm.
