What needed to be present in marine mud to form fossil fuels?
Carbon and Hydrogen.
Answer:
Mostly decaying organisms are needed to present in marine mud to form fossil fuels.
Explanation: When organisms and plants died and sank to the bottom of swamps and oceans, brown soil-like materials called peat are formed. Over millions of years, the peat became covered with sand, clay and other minerals and the peat is converted into layers of sedimentary rocks. After a long time, different type of fossil fuels are formed.

Answer:
Explanation:
a) Isotope, one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behaviour but with different atomic masses and physical properties.
b) The number indicates the isotope's mass number.
c) Isotopes can be told apart by their mass numbers. Isotopes of the same element have the same quantity of protons in their nuclei.

How do the properties of each of these materials vary? Paper and Cardboard, Plastic, Wood, Metals
PLEASE HELP NOW
The properties of all of these material vary from each other. Paper, cardboard and plastic are insulators and metals and conductors. Each of them has different physical properties.
What are physical properties ?The physical properties of a substance include properties which changes its physical structure, size, shape, phase etc. Solubility, conductivity, resistance etc. are also physical properties.
Here, paper, cupboard and plastic are insulators and they does not conduct electricity. Whereas, metals are very good conductors and they have wide range of applications in optoelectronic devices.
Each of these materials has different melting temperature and different uses. Their density also vary significantly. The paper is the less dense one here and metals are denser.

1. Using D10W and a vial of NaCl 4 mEq/mL, how many mL of NaCl are needed to prepare 250 mL of a
D10/NS solution?
a. 4.8mL
b. 9.6ml
c. 19.6mL
d. 154mL
To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

The corn crop in an area is prone to infestation by larvae from moths that feed on the cornstalks and ears of corn. The techniques used by two farmers to protect the corn crop are described below.
Technique A: Sprayed his corn crop with an insecticide. The insecticide is known to kill all honeybee, butterfly, and moth larvae.
Technique B: Used a genetically modified variety of corn. The plant produces an insecticide which selectively kills only the moth larvae as it feeds on the corn.
Which technique is likely to have less of an impact on the environment?
Technique B because it may help humans who consume corn to fight bacteria
Technique A because it kills a broader variety of insects to protect the corn
Technique B because it preserves the harmless insects and targets only the moth larvae
Technique A because insecticide use is better for preserving the environment.

The print fossil, original-remains fossil, petrified fossil, carbonized fossil, landform, igneous, metamorphic, sedimentary, cleavage, and geology are the respective matches as given in the question.
Print fossil is imprint of plant or animal and basically known as fossil impression. Original-remains fossil comprises of the original tissues and parts of organism and undecayed plant or animal part. Petrified fossil is replaced by a mineral. Carbonized fossil is only carbon remains. Landform is a mountain. Igneous is from magma.
Metamorphic is from physical and chemical changes. Sedimentary rocks are sandstone. Cleavage helps to identify rocks. Geology is the study of science of earth.

What is the traditional definition of gravity?
Answer:
A force of attraction between things that have mass. Gravity can act between objects that are not even touching. In fact, gravity can act over very long distances. However, the farther two objects are from each other, the weaker is the force of gravity between them.

Answer:
CO2 (Carbon dioxide)Explanation:
The right side is collored blue to indicate that the blood pumping through here is low on oxygen, but high in carbon dioxide. Because the blood is so low on oxygen, and high in carbon dioxide (a byproduct of Cellular Respiration), the blood will be pumped to the lungs where the CO2 is removed, and oxygen is taken in.

In an electrical wire, if instead of copper, plastic wire is used. Would it conduct electricity?Justify your answer.
Answer:
No, a plastic wire would not conduct electricity. This is because plastic is an insulator that does not allow electric current to flow through it. In a wire, electrical conductivity is provided by the movement of charged particles - typically, electrons. Copper is an excellent conductor of electricity because it has a high number of free electrons that are not bound to atoms and can move through the wire very easily. However, in a plastic wire, the tightly bound electrons of its atoms do not allow for the free flow of charges, thus preventing the passage of electric current.
Identify two characteristics shared among transverse waves, longitudinal waves, and surface waves.
Answer: For transverse waves, the waves move in perpendicular direction to the source of vibration.
For longitudinal waves, the waves move in parallel direction to the source of vibration .
They are similar within the sense that energy is transferred within the kind of waves.
Explanation:
The shared characteristics between traverse, longitudinal and surface waves include :
Traverse, longitudinal and surface waves are all mechanical waves They only transport energy without transporting matter.Mechanical waves are simply waves which requires a material medium to propagate. They include longitudinal, surface and traverse waves.
Also, all three waves transfer energy through a medium without the transfer of materials or matter in the medium.
Therefore, all three waves are mechanical waves and do not transfer matter.
