Answer:
Theory
Explanation:
A scientific theory is what best fits your description. A scientific theory basically explains aspects of the natural world. However, scientific theories are not just ideas, it is based on collaborative works that tests the idea through the scientific method. Theories are verified through repeated testing.
Scientific hypotheses can eventually become a scientific theory when results have been verified through repeated testing.
Answer:
Option-D
Explanation:
Arabidopsis is a model organism plant used by scientists all over the world to study the genetic mutations and the effect of various factors on the plant.
In the given case, it has been mentioned that the plants were growing in the drought or no water conditions and the high salinity or high salt conditions.
The high salt condition interferes with the absorption of other nutrients whereas, in less water condition, the loss of water from the plant not equals the absorption as a result of which the plant dehydrates.
Thus, Option-D is correct.
At really high pressures, carbon dioxide does form a liquid phase. Anyway, dry ice is much, much colder because carbon dioxide freezes at a lower temperature:-79 degrees Celsius or -109 degrees Fahrenheit!
Answer:
51.84%
Explanation:
p² + 2pq + q² = 1 and p + q = 1
p = frequency of the dominant allele in the population
q = frequency of the recessive allele in the population
p² = percentage of homozygous dominant individuals
q² = percentage of homozygous recessive individuals
2pq = percentage of heterozygous individuals
p = 0.72 => p² = 0.72² = 0.5184
=> Percentage of the rats are normal sized: 51.84%
