B) Suspect 2 is a match to the DNA evidence found on the victim.
Half life is the time taken by a radioactive isotope to decay by half of its original mass. In this case the half life of carbon-14 is 5500 years.
The original mass is 30 g and the new mass is 3.75 g.
New mass = Original mass × (1/2)^n, where n is the number of half lives;
3.75 = 30 × (1/2)^n
1/8 = (1/2)^n
n = 3
Thus, the time taken will be; 3 × 5500 = 16500 years.
D, I’m assuming that’s their is a another so you give on group nothing and the other group the vitamin C
Answer:
46 chromosomes
92 Chromatids
One DNA molecule
Explanation:
The interphase part of the cell cycle is divided into 3 sub-phases namely; G1 phase, S-phase and G2-phase
G2-Phase occurs when the cell grows more to make more proteins and organelles. This also when the cell reorganize its contents in preparation for mitosis. The number of chromosomes will therefore, remain the same but the DNA molecule will be one in preparation for mitosis where it can then divide into two
