Answer:
Radioactive isotopes has a characteristic half life that is ranging from less than a second to million of years.
Explanation:
One of the characteristics of radioactive material is that the radio active isotopes instantly gives off particles. This process is termed as radio active decay.For this activity pennies are used pennies headed up it means that nuclei have undergone radio active decay, or tails up it means that nuclei that haven't yet decayed.
Answer:
interphase
Explanation:
The cell cycle is divided into two main phases: interphase and mitotic phase (mitosis or meiosis).
Interphase is phase characterized by the the cell growth and DNA copy (replication). During this phase, the cell prepares for division, (mitotic phase).
Interphase has three phases:
G1 or Gap 1 - the cell grows in size and duplicates organelles
S1-replication of DNA
G2 or Gap 2 phase- the cell adds volume to the cytoplasmand repicates more organelles.
Answer:
Explained
Explanation:
Eight prophase cells, one metaphase cell,three anaphase cells, and four telophase cells. It results in 8 + 1+ 3 + 4 = 16 cells.This indicates that the remaining cells of 32-16 = 16 were in interphase.This means the cells spend the maximum amount of time in interphase.This time is equal to half the total cells.
So, if it's a 24-hour process,the interphase should spend 12 hours.
Six hours of prophase, 45 minutes in metaphase and 2 hour, 15 minutes in anaphase, and 3 hours in telophase.
