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
Answer:
b
Explanation:
due to soil erosion ,soil loses its mineral components as they get washed away during a time of flood ,thereby it can determine the minerals present in the soil .

this was sooooo long ago i forgot how to do this
Explanation:
Answer: Literally everywhere. Having an at least basic level of science helps you in day-to-day situations. For example, cooking. Not only is it crucial to understand the chemical and physical processes when cooking, you should also understand the complexity of how these micro and macromolecule exchange processes affect you and your body. Another prime example is your health, or human processes. You might not realize this, but your body is a plethora of complex, interconnected systems and networks that work hard 24/7 to maintain homeostasis (keep you alive). Understanding how our human physiques conduct themselves helps us gain the knowledge to be able to stay alive.
