<span>The propositions are:
A. The gas in the car is the digestive system that provides the necessary energy.
B. The frame of the car is the digestive system that provides structure and support to the body.
C. The exhaust system of the car is the excretory system that removes waste.
D. The engine of the car is the digestive system that circulates nutrients to the rest of the body.
E. The oil in the car is the excretory system that protects and coats the body.
The right answer is: C and D
*The exhaust system in the car removes waste from the engine like carbon dioxide, carbon monoxide, and several oxidated particles that are unuseful. The same thing for the excretory system in human, it excretes urea, creatinine, and urobillongen (all are wastes from a metabolism).
*The nutrient in the car are represented by the fuel, it is the component that gives energy to the wheels to roll.</span>
<span>How many different types of offspring (genotypes) are possible as a result of this cross, according to the punnett square? The correct answer is 3.
With three alleles we have a higher number of possible combinations in creating a genotype. Notes: As you can count, there are 6 different genotypes & 4 different phenotypes for blood type.</span>

The answer is B. Invasive species are successful in novel environments due to lack of a natural predator or competition. Therefore if the non-native share a niche with other fish in the lake ecosysem, there will definitely be competition for resources. This could lead to competitive exclusion of one species or resource partitioning between the species. Consequently, the non-native fish species will not invade the new environment unchecked.
