The external crystal form of a mineral Rounded: Any clast with smooth edges. Usually indicates abrasion by moving water or wind. Also the answer to this question is in magmas/ lavas many mineral grains are growing simultaneously. These grains grow into one another and form an interlocking texture.
Answer:
By monitoring changes in the population of a specific indicator species, scientists may draw conclusions about changes in a specific pollutant's levels. In addition, this method of pollution measurement demonstrates the impact of pollution on vulnerable species.
Explanation:
Answer:
Solid 1 has the smallest amount of plasma membrane per volume of cytoplasm
<em>Note: The question is incomplete. The attachment below gives the complete question</em>
Explanation:
The outermost surface of a cell is bounded by the plasma membrane which functions to maintain the integrity of the cell as well as control the movement of particles in and out of the cell.
The ratio of the surface area of a cell to the volume of the cell indicates how big the cell is. When the surface area to volume ratio is small, the cell is very big, but if the surface area to volume ratio is big, the cell is small.
From the attachment below, the surface area (plasma membrane) per volume of plasma of the rectangular solids are as follows:
Solid 1: 10/2 = 5 cm⁻¹
Solid 2: 12.18/2 = 6.09 cm⁻¹
Solid 3: 19.0/2 = 9.5 cm⁻¹
Solid 4: 34.24/2 = 17.12 cm⁻¹
Solid 5: 65.79/2 = 32.895 cm⁻¹
Solid 1 has the smallest amount of plasma membrane per volume of cytoplasm
<span>Survival of at least a few members of a population after a major environmental change is most dependent on 3) variations in many different traits in many individuals in the population.
Variation is important for a species which wants to survive huge changes in the environment. If they cannot adapt to their new surroundings, they won't be able to survive. This is where variation comes in - it enables a species to develop new techniques and traits necessary for survival.
