<u>Answer:</u>
<em>When the volume is constant the pressure increases with temperature. </em>
<u>Explanation:</u>
<em>Gay Lussac’s law precisely explains the relation between pressure and temperature of a system which has constant volume.</em> In a system which has constant volume an increase in temperature indicates increase in temperature as well.
The reason behind the observation of this trend is the change in <em>randomness of particles of the system. </em>
With increase in temperature the particle movement becomes random and fast. <em>The particles hit the container walls at an increased rate and the pressure of the system increase. </em>
Answer: The correct sequence in the expression of a trait is gene > protein > trait (Option B).
Explanation:
During gene transcription, a linear fragment of DNA referred to as a 'gene' is used as template to synthesize a complementary messenger RNA (mRNA) sequence.
Subsequently, this mRNA is then used as template to create a protein by a process called translation.
Moreover, phenotypic traits can be defined as all observable characteristics that an organism has.
The phenotypic traits are largely determined by the expression of either enzymatic or structural proteins, which interact to shape the phenotype of an organism.
In conclusion, the correct sequence in the expression of a trait is gene > protein > trait (Option B).
Small population size is your answer mate.
Answer: C). Extraction
Explanation:
Minerals are the inorganic susbtances obtain from the under surface of the earth crust. They are collectively found in the geosphere of earth.
The mineral formation is a long geomorphic process it does not involve any biological activity. After mineral formation mineral extraction is the next step in the resource cycle.
The extraction process involves mining techniques.
Answer: Subarachnoid
Explanation:
The space in the meninges below the arachnoid membrane and above the pia mater contains the cerebrospinal fluid. Cerebrospinal fluid is produced by choriod plexus( a cluster of capillaries) from the blood. Blood vessels traveling within the subarachnoid space deliver oxygen and nutrients to the spinal cord.
