Answer:
c
Explanation:
Random distribution of the Isopods should be 50/50 in A and B.
Chi-square = where O = observed frequency and E = expected frequency
Chamber O E Chi-square
A 18 10 = 6.4
B 2 10 = 6.4
<em>Total Chi-square </em>= 6.4 + 6.4 = 12.8
<em>Degree of freedom</em> = 2 - 1 = 1
<em>Tabulated Chi-square</em> (α = 0.05) = 3.8415
The calculated Chi-square exceeds the critical value, hence, it is significant and not due to random.
<em>The correct option is </em><em>c</em><em>.</em>
Cancerous cell just continue to divide giving rise to mases of cells called tumor.
Breast milk provides antibodies to fight diseases.
Breast milk is produced by mammary glands in the breasts and its main function is feeding an infant. Breast milk is the primary source of nutrition for newborns. The composition of the milk includes immune-boosting white blood cells, as well as stem cells, which can help organs develop, antibodies, proteins, amino-acids, oligosaccharides, growth factors, hormones, enzymes, vitamins, minerals…

Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes. However, unlike prokaryotic cells, eukaryotic cells have: a membrane-bound nucleus. numerous membrane-bound organelles (including the endoplasmic reticulum, Golgi apparatus, chloroplasts, and mitochondria)
