Answer:
Option D, Continents cannot cut through the ocean floor.
Explanation:
It was believed earlier that oceans were the land bridges that used to connect different geologic plates of planet earth earlier, had now sank down and thus there exists no connection between the tectonic plates. Therefore, without any link or connection, continents cannot cut through the ocean floor.
Also as per the Land Bridge Theory , there has been continuous shifting of dry land due to which identical land species on different continents were found.
Hence, option D is correct
Ansnswer:
False.
No Mendel principled talk about how different genes assemble unregulated with one another to develop reproductive cells
Explanation:
Gregor Mendel was a scientist and the founder of modern science genetics. He made so findings in 1865 and He proposed three laws and they are;
Law of independent assortment which states that two alleles from different genes separated independently to form gamete.
Law of segregation states that a pair of gene separated to for reproductive cells.
Law of dorminant inheritance states that in heterozygote, dorminant allele will masked the recessive allele.
If the results show that 21% of the nucleotides contain adenine, then the cytosine fraction in vivo is 29% and the thymine fraction is also 21% (options A and C).
<h3>Define double helix model of DNA?</h3>
- DNA is a double helix molecule made up of two long strands of nucleotides.
- There are four types of nucleotides in DNA, each containing a different nitrogenous base: adenine, guanine, thymine, cytosine.
- Adenine always pairs with thymine and guanine pairs with cytosine, according to the base-pairing rules.
- As a result, the percentage of adenine equals the percentage of thymine, and the remaining percentage equals guanine + cytosine (29 + 29 = 58 >> 58 + 21 + 21 = 100).
- Therefore, if the results show that 21% of the nucleotides contain adenine, then the percentage of cytosine in vivo is 29% and the percentage of thymine is also 21%
