answer is D ( totipotent cells can differentiate into more types of cells )
Answer:
Capillaries connect the arteries to the veins. The arteries deliver oxygen rich blood to the capillaries, where the exchange for oxygen and carbon dioxide occurs.
Explanation:
Hope this helps!
Answer:
1) Founder effect and genetic drift: Small colonizing population did not represent the original gene pool of the source population and was more likely to undergo genetic drift.
2) Natural selection
Explanation:
Evolution of the population of the finches with larger beaks might have occurred due to one of the following mechanisms:
a) Founder effect and genetic drift: Since the size of the colonizing population was small, it did not carry all the genes and their alleles present in the gene pool of the original population. The small population size made it more likely to evolve by any chance event.
b) Natural selection: The availability of different food types in the new habitat led to the natural selection of the larger beaks as the finches with larger beaks might have been able to better exploit the available food resources.
The right answer is 3 nucleotide bases.
5'-CGGCACCGCCCTAAGTCTCT-3'
5'-AGGCACCGCCCTAAGTCTAC-3'
It would be necessary first to align the two sequences side by side so as to be able to compare them, and they should also be in the same direction.
The nucleotides marked in bold are the nucleotides that differ between standard and O. Kisutch.
These nucleotide changes are necessarily due to substitution mutations that exchanged one nucleotide for another in the same location.
D because destroying toxens and destroying tissues are caused by bacteria
