Earth would fly off into space in a straight line if the gravity
between Earth and the Sun ended
Explanation:
The Earth's orbit is made through gravity and inertia. If gravity between the Sun and Earth had ended, inertia would make the Earth travel in a straight line because there is no gravity to pull it towards the sun and keep it in motion.

Carbon-14 an isotope of carbon is found in all living things. Find information on how archaeologists use this to calculate the age of fossils and some ancient remains.
Answers
Answer:
Radiocarbon dating is the most common method by far, according to experts. This method involves measuring quantities of carbon-14, a radioactive carbon isotope — or version of an atom with a different number of neutrons. Carbon-14 is ubiquitous in the environment.
Explanation:
Carbon-14 an isotope of carbon is found in all living things. Archaeologists use this to calculate the age of fossils and some ancient remains by radioactive dating.
Radioactive dating is also known as radiometric dating. It is a method that is used to determine the age of rocks and fossils by measuring the decay of radioactive isotopes. It is based on the principle that certain isotopes of elements are unstable and undergo radioactive decay over time, transforming into different elements or isotopes.
By measuring the ratio of parent isotopes to daughter isotopes in a sample, scientists can estimate the age of the sample.

Temperature, humidity, pressure, gravity, altitude, vibration, stress, strain, and illumination are among the variables.
What are precision and accuracy?
Accuracy is the capacity of an instrument to measure the precise value. In other words, it refers to how closely the measured value resembles a reference or genuine value. Small readings can be taken to increase accuracy. The calculation's inaccuracy is decreased by the little reading.
The precision of a material is defined as the degree to which two or more measurements agree with one another. It is incredibly precise but not always accurate to measure something if you weigh it five times and get 3.2 kg each time. Accuracy is not necessary for precision.
The degree to which a measurement is accurate in relation to its real value. The degree to which the same results are produced by repeated measurements under the same circumstances is known as precision.
Therefore, temperature, humidity, pressure, gravity, altitude, vibration, stress, strain, and illumination are among the variables.

Proper lane placement can include positioning your car...
A. away from other cars.
B. 36 inches from the right or left line.
C. one inch from either lane line.
Answers
Proper lane placement can include positioning your car 36 inches from the right or left line. Therefore, option B is correct.
What is lane positioning ?Using different lane positions to make adjustments for potential problems and create larger space between car and problem situations. Lane position is the placement of car in the center, on the right, or on the left of a lane. The width of a lane is twelve feet on most highways or streets.
There are three main positions are lane position 1 is center of lane, lane position 2 is left side, and lane position 3 is right side. Position 2 is left side of lane is for car.
Position 3 is a vehicle placement to the right when a restriction to path of travel or your line of sight occurs. Proper lane placement can include positioning your car 36 inches from the right or left line.
Thus, option B is correct.

Which of these statements best describes which traits are expressed by an organism? A. An organism expresses all the traits for which it carries genes.
B. An organism expresses only the traits whose genes are inherited from a parent.
C. An organism expresses only the traits whose genes it will pass on to its offspring.
D. An organism expresses some traits for which it carries genes while others are dominant
Answers
The statement that best describes which traits are expressed by an organism is A.
An organism expresses all the traits for which it carries genes. This is because an organism's traits are determined by the combination of genes it carries, which includes both dominant and recessive genes. Even if a trait is not expressed in an organism, it can still be carried in its genes and passed on to its offspring. Therefore, all the traits for which an organism carries genes have the potential to be expressed in either the organism or its offspring.
B-An organism expresses only the traits whose genes are inherited from a parent.

You and your family have decided to plan a trip to the Grand Canyon this summer. The pictures below show the features of a part of the Grand Canyon and where the Grand Canyon is located (red star). Explain how the Grand Canyon was likely formed and how it will continue to change in the future. In your response, be sure to include the following: Earth’s geologic processes that have likely shaped the landform
A general timescale of how long this process may have taken
Evidence from the unit and relevant unit vocabulary (mechanical/physical weathering, erosion, sedimentation)
Answers
The Grand Canyon began its formation about 5 my ago by the erosive action of the Colorado River. Its sedimentary layer composition reflects its history, keeping fossilized living forms that used to inhabit the area.
--------------------
The Grand Canyon formation began approximately 5 million years ago, thanks to the erosive action of the Colorado River.
The strength of the colorado river caudal, together with deglaciation and humidity factors, began to cause an uncontrollable erosion process in these lands that were previously part of the sea bottom.
Originally many strata and sediments accumulated at the bottom of the ocean. With time these extensive areas were exposed when the Rocoses Mountains got formed by the end of the cretaceous (70 million years ago).
Now, by looking at the composing layers, it is possible to understand its formation.
The Grand Canyon is almost entirely composed of sedimentary rock.
It was formed while sediments of sand and mud got deposited in thick layers at the bottom of the ocean and got compacted through the pass of time until becoming a rock.
Sedimentary rocks have been chronologically accumulating for years, reflecting the geological formation known as superposition.
According to this sedimentary deposition, we can distinguish the older rocks located in the deepest areas from the younger rocks in more superficial layers.
Each layer keeps fossilized organisms that used to inhabit this area in the past.
