this is for science, and if i get the questions right, I pass, but the teacher never taught us the lesson, idrk y. so i really need help:( Im giving away 11 points so please give me your best answers ;)



1. As an astronaut travels from the surface of Earth to a position that is four times as far away from the center of Earth, based on the Law of Gravity which of the following statement is true?



a. mass remains the same and the gravitational pull from Earth decreases


b. weight remains the same and the gravitational pull from Earth changes


c. weight increases and the gravitational pull from Earth stays the same


d. mass decreases and the gravitational pull from Earth increases


2. A satellite is sent into orbit around the Earth, In which of the following situation would the gravitational force be the greatest?

3. High and low tides are the regular pattern of rising and sinking ocean-water levels. They are caused when the sun’s gravity and the moon’s gravity pull on ocean water. The moon’s gravity has a greater effect on Earth’s oceans than the sun’s gravity. Why would the moon have a greater effect than the sun?



a. The moon has less mass than the sun.


b. The moon is closer to Earth than the sun.


c. The moon is not as hot as the sun.


d. The moon has less mass than Earth.




4. Which statement about the universality of gravity is false?



a. The gravitational force between two objects depends only on their masses.


b. Any two objects that have mass also have a force of gravity acting between them, no matter how far apart they are.


c. The gravitational force between two objects increases if the objects move closer together.


d. The gravitational force between two objects increases if mass is added to one object.

The motion of an object can be described by its
OA. speed.

A newborn child was brought to the hospital nursery before he was marked with his parents' names. The hospital workers must use what they know
about genetic outcomes to determine whom the child belongs to. They use his traits to help them. The baby has freckles (F dominant), and attached
earlobes (I recessive). They believe that the baby most likely belongs to a couple in which the man has attached earlobes but no freckles. It is known that
the woman is heterozygous for freckles and earlobe type.
Complete the Punnett square below to determine the probability that the child belongs to this couple. List the possible combinations of the father's
alleles across the top and the possible combinations of the mother's alleles down the left side. Then write your answer in the space below. Include a
brief statement explaining how you reached your answer.

A researcher attempts to use a segment of ribosomal RNA as a molecular clock to calculate the date of the last common ancestor of two species. He finds that the two species diverged from a common ancestor 150 million years ago. These particular species have abundant fossil records that strongly suggest that these species diverged 100 million years ago. Which of the following answer choices best describes a reason for the discrepancy in the date of the last common ancestor of these species?

A. Ribosomal RNA is not a reliable molecular clock and should not be used for dating.
B. The neutral mutation rate used in calculating the last common ancestor date may not have been accurate.
C. It is highly likely that the two organisms did not share a common ancestor, so the results are invalid.
D. A large portion of the ribosomal RNA is not vital to survival, so it is not likely to be well preserved.

Piyush is asked to classify samples of bacteria as bacilli, cocci, or spirilla.
