how do fossils give evidence of continental drift? List 2 examples using fossils found on different land masses.

Biology
1 answer:
Ivanshal [37]2 years ago
5 0

Answer:

Explanation:

There are many examples of fossils found on separate continents and nowhere else, suggesting the continents were once joined. If Continental Drift had not occurred, the alternative explanations would be:

The species evolved independently on separate continents – contradicting Darwin’s theory of evolution.

They swam to the other continent/s in breeding pairs to establish a second population.

Proteoglycans are a group of macromolecules formed from: a. proteins and glycosaminoglycans. b. proteases and glycosaminoglycans
Marianna [84]

Answer:

Proteins and polysaccharides.

Explanation:

Proteoglycans are heavily glycosylated proteins. These proteoglycans are present in the extracellular matrix of the animal cells and acts as a lubricant for the cells.

Proteoglycans are proteins that are covalently bonded with muco polysaccharidse. Proteoglycans are formed by the bonding between proteins and carbohydrates ( polysaccharides). Proteoglycans can combine with collagen to form cartilage and may affect the stability of a protein.

Thus, the correct answer is option (E).

Assuming dragon genetics follows the same rules as fruit flies, what ratio of genotypes would you expect if the genes were not l
andrew11 [14]

Assuming dragon genetics follow the same rules as fruit flies, we would get the same possible genotype for all 16 offspring provided that the genes are not linked.

Considering dragon genetics, flame eyes (F) are dominant to blue eyes (f) and burbling (B) is dominant to whistling (b).

Now, a dihybrid cross between two homozygous blue-eyed, whistling dragons will yield 16 offspring all with the same possible genotype .i.e. homozygous blue-eyed, whistling type.

Morgan through experiments on fruit flies observed that when the two genes in a dihybrid cross were situated on the same chromosome, the proportion of parental gene combination were much higher than the non-parental type.

He attributed this due to the physical association or linkage of the two genes and coined the term 'linkage' to describe the physical association of genes on a chromosome. The term 'recombination' is to describe the generation of non-parental gene combination.
