a. True
Explanation:
Bruce Wallace was a professor emeritus of genetics who performed many population studies. He worked in 1958 at the University of Cornell as a professor of genetics. In 1963, he performed a population study wherein the recessive allele <em>It </em>was at a frequency of 0.5. The population was propagated for 10 generations and the frequency of <em>It</em> for each generation was determined.
The result of this study showed that<em> lt/lt </em>died without reproducing, whereas, individuals with genotype <em>+/+ </em>were normal.
Answer:
The correct answer would be - 9 hours.
Explanation:
The half life of a drug is the time that is required to decrease or reduced to one half of the its original achieved level or the highest amount previously taken. The half life of drug is also known as the time a drug take to complete its action.
At a dose of 500 mg the Fluoxitine drug would be 250 mg in 3 hour as it is given that half life of this drug is 3 hours, 125 mg in 6 hours, and in the end 62.5 mg in 9 hours.
Thus, the correct answer is : 9 hours.
Each cell is alive even if it is part of a multi celled body, and all living organisms consist of one or more cells. Also, cells reproduce by dividing so it follows that all existing cells must have arisen by division of other cells. As a cell divides it passes it hereditary material- its DNA- to offspring.
Answer:
At dawn the squid prepares to hide in the sand for the day and it ejects about 95% of the bacteria from the light organ in order to reduce or stop the growth of bacteria population in the squid. This will prevent the bacteria population from reaching a level too high for the squid to support.
Bacteria and plants both have cell wall and this is the main similarity !
in accurate all bacteria, cell wall may not be present !
