The greater an object's ____ the stronger the gravitational force on it.
A. mass
B. distance
C. weight
Answers
Answer:
The greater an object's mass the stronger the gravitational force on it.
The greater an object's mass, the stronger the gravitational force on it.
What is the force of gravity?The force of gravity depends directly on the mass of the objects and inversely on the distance between them. Therefore, an object with a greater mass will have a stronger gravitational pull on other objects, regardless of their distance apart.
The weight of an object is a measure of the force of gravity on it and is equal to the object's mass multiplied by the acceleration due to gravity. So, while mass and weight are related, they are not the same thing. Mass is a measure of an object's amount of matter, while weight is a measure of the force of gravity acting on an object.

Granite takes much longer to form than basalt. How will the size of the crystals in granite be different from the size of the crystals in basalt?
Answers
Answer:
The size of the crystals in granite will be different from the size of the crystals in basalt depending on how they are formed and how they are cooled which determines the nature of the crystals they produce. Granite takes a much longer time to form than basalt because granite takes a very long time to cool down since it is intrusive giving minerals to be well-formed and producing a bigger size of crystals with individual mineral grains that are can be seen without the need for bigger magnification. While basalt crystals are much smaller as the crystals form very quickly because the magma comes out of the earth and cools quickly giving rise to fine-grained minerals.
Explanation:
Granite and basalt are both igneous rocks.
Granite takes a longer time to cool as it hardens under the earth's surface causing the delay in cooling while basalt takes a shorter time to cool as it hardens above the earth's surface.

How does the nucleus, cell membrane, and ribosomes work together?
Answers
Answer:
Eukaryotic cells have a true nucleus, which means the cell's DNA is surrounded by a membrane. Therefore, the nucleus houses the cell's DNA and directs the synthesis of proteins and ribosomes, the cellular organelles responsible for protein synthesis.
OR
In the nucleolus, new ribosomal RNA combines with proteins to form the subunits of the ribosome. The newly made subunits are transported out through the nuclear pores to the cytoplasm, where they can do their job.
The nucleolus inside the nucleus produces ribosome components, which are synthesized just outside of the nucleus form ribosomes.
The spindle then sends mRNA towards the ribosomes, which is used to code for protein synthesis.
Other organs in the cell, including the mitochondria and lysosomes, are surrounded by lipid membranes that isolate them from other components in the cell.

Use the drop-down menus to match each part of the scenario to the correct scientific practice.
Kiran records the height of each plant―those with a colored filter and those without.
Kiran explores the growth of a plant in natural light, then repeats the experiment with the same plant type but different colored filters.
Kiran turns in a written lab report to her science teacher.
Kiran wonders, “Will colored light affect the growth of a plant?”
Kiran writes in her notes that adding a colored filter over a plant affects its growth because the heights of the plants under the colored filters were less than the height of the plant with no filter.

The graph shows the changing levels of hormones during menstruation and ovulation. What happens to hormone levels during ovulation, and why is this important?
Answers
Answer:
The estrogen level decreases during the ovulatory phase, and the progesterone level starts to increase. And it is important, because hormones that are being releazed stimulates the egg to move from the fallopian tube, which then leads to menstruation.
Explanation:
The ovulatory phase begins with a surge in luteinizing hormone and follicle-stimulating hormone levels. Luteinizing hormone stimulates egg release (ovulation), which usually occurs 16 to 32 hours after the surge begins.
Answer:
Hormone levels generally decrease.
