Answer:
20 ( B )
Explanation:
Given data:
a and b are 10 map units apart
b and c are 20 map units apart
a and c = 30 map units apart
<em>condition </em>; Triple heterozygote testcrossed
number of progeny = 1000
<u>Determine the number of double crossover result </u>
P( crossover between a and b ) = 10/100 = 0.1
P( crossover between b and c ) = 20/100 = 0.2
p( double crossover ) = 0.1 * 0.2 = 0.02
hence number of double crossovers = number of progeny * 0.02
= 1000 * 0.02 = 20
From this information, you can conclude that the organism is NON FASTIDIOUS.
A non fastidious organism is one who will grow in most culture mediums, that is, it is not selective when it comes to nutrients and will use any available source as a source of food and energy.
The type of bond that are show in the diagram above is option C which is metallic bond and it is a chemical bond or electrostatic force of attractions that exist between conducted electrons in metal ions.
<h3>What is metallic bond?</h3>
Metallic bond is a form of chemical bond or force of electrostatic attractions that exist between the positively charged metal ions which give room for conduction of electricity or heat.
This type of bond only occur in metallic substances or objects alone. This is characterized by high boiling and melting points.
Therefore, The type of bond that are show in the diagram above is option C which is metallic bond and it is a chemical bond or electrostatic force of attractions that exist between conducted electrons in metal ions.

The Serratus anterior in man is homologous to the Serratus ventralis muscle in the cat. The Serratus anterior is a muscle that originates on the surface of the 1st to 8th ribs at the side of the chest and insects along the entire anterior length of the medial border of the scapula. The Serratus anterior acts to pull the scapula forward around the thorax. Serratus ventralis in the cats looks like fingers because it attaches to the ribs, but has nothing to attach to between the ribs.
