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.

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.

Explanation:
How did this piece of evidence change your thinking about the channel on Mars? Explain your ideas below.
The piece of evidence changed thinking about the channel on Mars because it shows that the rock was formed next to flowing water as such rock formations exist on Earth and were formed by flowing water.
Was there flowing water on Mars ?The geologic process that could have created the channel on Mars is water moving. We can infer from the image that water running across the terrain on Mars created channels similar to those on Earth.
We can claim that the flowing of water creates the channels on Mars because when the water runs for a long period from the same region, it takes the sediments and creates channels.

Draw a model of Earth’s orbit around the Sun that explains why Earth has four seasons. Be sure to show the tilt of Earth’s axis. The model need not be drawn to scale.
Answer:
i gave you guys the link to the drawing
Explanation:
Earth is revolving around sun along with rotation on its own axis with tilt in the axis. The different positions of earth with respect to sun creates different seasons in earth.
What are seasons?Different distance of earth from the sun at different times make the climate of earth also different. The seasons experienced in earth are summer, winter, spring, autumn and monsoon.
The closes distance of earth with sun make the season summer and the farthest distance creates winter seasons. The slight tilting in the earths orbit on its rotation make the heat radiated from the sun different in different regions.
Each square centimeter of the earth receives more light and heat while the sun is overhead since it is dropping directly on you. Less heat can be absorbed when the sun is lower in the sky because the light is more evenly distributed over the earth's surface.
The sun is higher when you are on the portion of the earth where the axis points more towards the sun and lower when you are on the part of the earth where the axis points away from the sun because of the tilt of the earth's axis.

Individual organisms have a variety of traits that make them different from each other. Traits such as fur color and eye color vary from one individual to another. What determines the traits of an individual organism?
Answer:
Traits can be determined mostly by genes but can be by environmental factors, or a combination of both. Traits can be qualitative (such as eye color) or quantitative (such as height or blood pressure) A given Trait is part of an individual's overall phenotype.
