Explanation bc the solid has particles more packed liquid less packed and gas is vey loose
Answer:
A closed system is a system where only energy is transferred or exchanged with its surroundings. Matter is not part of this exchange. An open system includes the transfer and exchange of both matter and energy with the system's surroundings.
Explanation:do u understand
Answer:
Volcanoes are formed at the divergent and convergent plate boundaries.
<u>During a divergent plate motion, along the mid-oceanic ridge, seafloor spreading takes place. Here it is represented by location B. Due to this, the magma becomes extremely hot and exerts an upward pressure towards the seafloor</u><u>. </u><u>As a result of which the ocean floor slowly rises up forming sea volcanoes.</u> The eruption takes place and the lava forms and deposits on the seafloor, near and along the mid-oceanic ridge. As this region undergoes continuous spreading, so the crust comprised of these rocks slowly moves away from the ridge.
Answer:
The correct answer would be B-80/200.
Allele frequency is defined as relative occurrence of the allele at a particular locus in a given population.
We have a sample population of 100 chickens where
Frequency of homozygous dominant trait (CC) = 45
Frequency of homozygous recessive trait (cc) = 25
Frequency of heterozygous dominant trait (Cc) = 30
Total alleles would be = 100 x 2 = 200
Total number of observed copies of C (dominant allele) = (45 x 2) + 30 = 120
Similarly, number of observed copies of c (recessive allele) = (25 x 2) + 30 = 80.
Hence, the frequency of allele C = 120/200 = 0.6
Frequency of allele c = 80/200 = 0.4
