Answer:
Hardness of a mineral is defined as the resistance to breaking, and density is defined as the mass of a substance per unit volume.
The density and hardness of a mineral, that is formed from through metamorphism are relatively much harder because the metamorphic minerals are formed under extremely high temperature and pressure conditions. These are high-grade minerals.
On the other hand, the density and hardness of a mineral formed through evaporation are much weaker in nature, because these minerals are formed when the water is eliminated due to the high rate of evaporation.
So, it can be concluded that the density and hardness of as mineral formed through the metamorphic process is highly stronger and harder than those that are formed through evaporation.
Answer:
Option (1)
Explanation:
Sediments are defined as broken materials such as rock fragments, soil particles, that are transported from one place to another by the agents such as wind, water and ice. The sediments are formed from the weathering of rock bodies.
The source of a sediment refers to the point (location) from which the sediments are originated.
The fragments of other rocks can be considered to be a source of sediment because these are broken fragments were initially a part of another rock, that eventually weathered, and eroded and deposited at a different place.
hence, the correct answer is option (1).
Answer: The correct answer is -
C) the child inherited chromosomes from both parents.
The child inherits 50% of the chromosomes from his father and other 50% from his mother (through fusion of male and female gametes that are sperm and egg respectively).
Due to this, child exhibits some of the paternal traits and some of the maternal traits. As per the given information in this question, mother is short with black hair and father is tall with red hair. The child produced is tall with black hairs. This also suggests that tall height and black hair are dominant traits (depicted by dominant gene variant) that suprress the expression of recessive trait (depicted by recessive gene variant), which are short height and red hairs.
