Answer:
Explanation:
In metaphase (a), the microtubules of the spindle (white) have attached and the chromosomes have lined up on the metaphase plate. During anaphase (b), the sister chromatids are pulled apart and move toward opposite poles of the cell.
Answer:
11.7 g in 1 L of water.
Explanation:
Molarity (M) or Molar concentration is a measure used in chemistry for solutes in a solution.
It is defined as mol/ L (number of moles per litre).
0,2 M means we have 0,2 mol/ L
In order to know how many grams this means we need to look up the molecular weight of the solute. In this case NaCl: 58.443 g/mol
= 
X= 
X= 11.69 g
The solution has 11.69 g of NaCl in 1 L of water since its an adequate polar solvent for NaCl dissolution.
Answer:
The correct answer is option d.
Explanation:
An illustration of epigenetic change is a microbe, which can stimulate modifications in the host DNA, causing suppression of defenses or weakening of individual cells. Epigenetic changes modify the physical composition of DNA.
One of the examples of epigenetic change is DNA methylation. DNA methylation refers to the supplementation of methyl group, which inhibits some of the genes from getting expressed. One of the conditions of DNA methylation is cancer.
In the majority of cancer, the tumor cells go through global hypomethylation. The tumor suppressed genes seem to turn highly methylated in the conditions of cancer.
Genetic Change in Viruses. Viruses are continuously changing as a result of genetic selection. They undergo subtle genetic changes through mutation and major genetic changes through recombination. Mutation occurs when an error is incorporated in the viral genome
