What is density? Q1 options:

the amount of salt in water

the amount per unit volume of a particular material

a measure of salinity

the weight of water

Q2 (0.25 points)
As the amount of salt in water increases, the of the water increases.

Question 2 options:

humidity

temperature

size

density

Q 3 (0.25 points)
Deep, cold water is the . Warm, shallow water is the .

Question 3 options:

densest; densest

densest; least dense

least dense; least dense

least dense; densest

Question 4 (0.25 points)
Which layer of the ocean is the least dense?

Q4 options:

they are all the same

closest to the ocean floor

closest to the surface

middle layer

Q1: C. salinity Q2: density Q3: B. densest, least dense Q4: C. closest to the surface

Explanation:

Q1: The term "salinity" refers to the concentrations of salts in water or soils.  Q2: when the amount of salt in the water increase which usually gathers mostly at the shallow top of the ocean which is where the warm shallow water gathers, when the warm water has enough salt in it, it sinks to a deeper location causing its density to heighten and that's also what makes it cold.  Q3: When layers form in the ocean, the water containing the most dissolved salt tends to form the bottom layer. The water having the least amount of salt is usually on top, because it is the least dense.  As more solids are dissolved in water, the water becomes more dense.  Q4: Cold water has a higher density than warm water. Water gets colder with depth because cold, salty ocean water sinks to the bottom of the ocean basins below the less dense warmer water near the surface.  I really need brainliest please do so.

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle
