Answer:
The main difference between limestone and marble is that limestone is a sedimentary rock, typically composed of calcium carbonate fossils, and marble is a metamorphic rock. Limestone forms when shells, sand, and mud are deposited at the bottom of oceans and lakes and over time solidify into rock
Explanation:
This layering is a result of the process of metamorphism. Metamorphism is the changing of rocks by heat and pressure. During this process, rocks change either physically and/or chemically
Answer:
Dry air.
Explanation:
One definition of dry air is a theoretical sample of air that has no water vapor. Another definition of dry air is air that has a low relative humidity. When the relative humidity drops below about 40%, the air feels dry to the skin.
B only in the nucleus and rough ER
Answer:
d. pxp +2pq
Explanation:
The formula for genotype frequency for a population in Hardy-Weinburg equilibrium is as under:
p² + 2pq + q² = 1
where, p = dominant allele
q = recessive allele
Here,
p² represents frequency of homozygous dominant genotype
2pq represents frequency of heterozygous genotype
q² represents frequency of homozygous recessive genotype
Also, although the genotypes p² & 2pq are different from each other yet phenotypically they both will collectively produce dominant trait i.e. free ear lobes not attached earlobes. So the term "p² + 2pq or pxp + 2pq" represents the frequency of the individuals who show the dominant phenotype in this particular population. Dominant phenotype will comprise 75% of the population.
Correct answer: D). Through an article published in a scientific journal
The first way by which the biology researchers present the result of their latest research is by publishing an article in the scientific journals. Scientific journals are a periodical publication that helps to report the progress of science by reporting new research.
Journals are archived and it is read by other people in the near future. Nowadays some journals are peer-reviewed and it is used by the scientist. it gives the scientist the most accurate and long lasting information about the latest research on science and technology.
