Cortés's army besieged Tenochtitlán for 93 days, and a combination of superior weaponry and a devastating smallpox outbreak enabled the Spanish to conquer the city.
B. All the cells of the body have the same DNA, but use different parts of it.
C. All the cells of the body are exactly the same as the original zygote cell.
D. All the cells of the body have pieces of the original cell’s organelles
Answer:
B
Explanation:
Different cells use different parts of the DNA strand to perform their functions
Answer: B
Explanation: How does a complex organism such as a human develop from a single cell—a fertilized egg—into the vast array of cell types such as nerve cells, muscle cells, and epithelial cells that characterize the adult? Throughout development and adulthood, the process of cellular differentiation leads cells to assume their final morphology and physiology. Differentiation is the process by which unspecialized cells become specialized to carry out distinct functions. All the cells of the body have the same DNA, but use different parts of it.

The probability that an offspring of the cross shown above will have the genotype Bb is 1:2. The correct option is D.
Alleles are the variations of the gene or trait of an organism. One gene contains a variation of the same type of trait. These traits come to form the mother and the father of the offspring.
They are of two types, the dominating and recessive. The dominating allele is denoted by a capital letter and the recessive gene is denoted by a small letter.
Here, the dominating allele is brown fur, B and the recessive allele is b, white fur. When crossing over happens, there is the probability of having the genotype Bb is 2:4 which will be 1:2.
Thus, the correct option is D. 1:2.

Answer:
D, 1:2
Explanation:
There are two squares that have Bb, and two that don't. Therefore, 2/4 is equivalent to 1/2
Answer:
Incorporating radioactive nucleotide must be done to ensure DNA made is a laboratory is radioactive
Explanation:
Radioactive nucleotide are generally used in the detection of some specific nucleic acid series. These are the typically incorporated inside the DNA and RNA series for detection as well as analysis. These nucleotide involves radioactive phosphates, digoxygenin, biotin, fluorophores and enzymes. It was first used in 1935 by George de Hevesy. P32 and S35 labelled as the nucleic probes and now the phosphates is being in large use. Hydrogen can also be used in-situ hybridisation which gives greater resolution and less sensitive in long exposure.
