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:
1. Make sure there are lots of bike paths
2. Design roads that work well with the area's public transportation
3. Include an HOV lane in the design
Explanation:
Green transportation planning is a form of planning in which roads are designed such that individuals are discouraged to drive alone on the road and at the same time utilized more environmentally friendly means of transportation. It also includes designing adequate lanes or paths for specific kinds of traffic or transportation.
Hence, in this case, the correct answers are:
1. Make sure there are lots of bike paths
2. Design roads that work well with the area's public transportation
3. Include an HOV lane in the design
Answer:
homeostasis
Explanation:
An endocrine system refers to a series of ductless glands and organs responsible for the production and secretion of hormones that are used by the body for the performance of various functions such as metabolism, controlling growth, reproduction, mood, sleep, etc. These hormones are secreted directly into the circulatory system (blood) and then transported to the organs and tissues in the body.
Basically, the endocrine system contributes significantly to the state of homeostasis in the body.
Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment ideal to enhance life and proper functionality.
For example, if a person becomes infected with a pathogen such as a virus. The internal stimulus that most likely takes place in order for their body to maintain homeostasis is that their core temperature increases. This is simply because pathogens such as a virus do not thrive or survive in a hot environment; they're naturally allergic to high temperature (heat).
In conclusion, homeostasis is the term used to describe the maintenance of a constant internal environment or balance by living organisms such as humans and animals.

Answer:
Natural selection occurs if four conditions are met: reproduction, heredity, variation in physical characteristics and variation in number of offspring per individual.
