The test that they can use in differentiating the gypsum and
quartz which are considered to be minerals is the mineral test. The mineral
test can differentiate the hardiness of the minerals, as well as their;
acidity, magnetism, streak, specific gravity and even their tenacity.
The statement 'Exploring the relationship between the material in a rock sample and its hardness' correctly describes an experimental investigation (Option C).
<h3>What is an experimental investigation?</h3>
An experimental investigation is defined as a procedure used in the scientific method to test an explanation or hypothesis, which can be confirmed or rejected.
In conclusion, the statement 'Exploring the relationship between the material in a rock sample and its hardness' correctly describes an experimental investigation (Option C).

Answer:
The system of measurement that is used through out the world is know as <u>International System of Units or, in French, Système International (SI).</u>
<u />
Explanation:
In order to describe motion, scientists use SI units to describe the distance an object moves.
<u>In system international (SI) or metric units, motion involves the units meters and seconds. </u>
Due to the consistency of units used the information described by one individual in a country is easily understandable by someone else in a different country .
For example: if someone describe the speed of an object to be 30 meters per second, anyone using the same units can understand this. whereas , the use of units such as foot per second is understandable to only small number of countries
Answer:
The correct answer is plants have two parts life cycle spending one part of their life in diploid phase and the other part in the haploid phase,human spending their lives in diploid phase and produces gamets that are haploid.
Explanation:
There are two stages in the life cycle of plant one is gametophyte stage which is haploid and the other is sporophyte stage that is diploid.
but in case of humans the overall life cycle proceed in diploid phase and produces gamets that are haploid.
In case of human male produces haploid gamet known as sperm and the female produces haploid gamet know as ovum. The sperm and ovum fuses to form diploid zygote,
The number and appearance of chromosomes in a cell is called a karyotype. A karyotype can only be seen and studied with a microscope. ... Karyotype analysis can reveal abnormalities, such as missing chromosomes, extra chromosomes, deletions, duplications, and translocations.
