Which metal is used for cathodic protection? The simplest method to apply cathodic protection is by connecting the metal to be protected with another more easily corroded metal to act as the anode. Zinc, aluminium and magnesium are the metals commonly used as anodes. What is the difference between sacrificial anode and impressed current? The […]
How do you calculate ploidy?
How do you calculate ploidy? Ploidy can be assessed either by chromosome number or by flow cytometry using the DNA index (DI), the ratio of fluorescence in leukemic blasts compared to normal cells. Normal diploid cells have 46 chromosomes and a DI of 1.0, hyperdiploid cells have higher values, and hypodiploid cells lower. What does […]
What happens if u eat chalk?
What happens if u eat chalk? Chalk is considered non-toxic in small amounts. If large amounts are eaten, it can be irritating to the stomach and cause vomiting. Chalk can be a choking hazard for very young children. CAUTION: Eating pool or billiard chalk can be different than school and blackboard chalk because it may […]
What would happen if solar winds hit Earth?
What would happen if solar winds hit Earth? The most powerful solar storms send coronal mass ejections (CMEs), containing charged particles, into space. If Earth happens to be in the path of a CME, the charged particles can slam into our atmosphere, disrupt satellites in orbit and even cause them to fail, and bathe high-flying […]
