Answer:
Engine is very much similar to the muscular system in a car.
Explanation:
The system is made up of the tissues which work with skeltal system to control the movement of the body is called Muscular System. In a car the engine is very much similar to the muscular system. They both help their systems to move. Without them the car or body would not going to operate.Like the human body car parts are also specialised & perform specific tasks, but they all depend on each other.Many would compare the engine of the car with heart of human body.The heart is the engine of the body just like the car. Our brain is very much similar to the the car's computer system or CPU.Every car is powered by an engine and most cars use an internal combustion engine which runs on gasoline.A car's overall power is a function of the size of engine as well as the factors such as timing of combustion and the type of transmission used.

Answer:
0.035
Explanation:
<u>cv+ is the wild-type dominant allele over cv, therefore:</u>
- cv+cv+ and cv+cv cause wild-type phenotype for crossveinless
- cv cv causes the crossveinless phenotype
<u>Sb is a dominant mutant allele over wild-type Sb+, therefore:</u>
- Sb Sb and Sb Sb+ cause Stubble phenotype
- Sb+ Sb+ causes wild type phenotype for Stubble
<h3><u>Test cross</u></h3>
It's the cross between the heterozygous female with a homozygous recessive male. Remember that cv and Sb+ are the recessive alleles.
X 
-The male produces only 1 type of gamete: cv Sb+
-The female produces 4 types of gametes:
- cv Sb+ ] Parental
- cv+ Sb ] Parental
- cv Sb ] Recombinant
- cv+ Sb+ ] Recombinant
The genes are linked and separated by 7 map units. A distance of 7 mu means that 7% of the resulting gametes will be recombinant. Because there are 2 possible recombinant gametes, each of them will appear in 3.5% of the cases.
The genotypes and proportions of the offspring resulting from the test cross can be seen in the Punnett Square. The phenotypically wild-type individuals will have the genotype cv+ Sb+ / cv Sb+ (heterozygous for crossveinless and homozygous recessive for Stubble) and a 0.035 proportion.

Answer:
<em>decreased variation in the shades of red over time because no form of the trait is advantageous</em>
Explanation:
Natural selection tends to favor those organisms which are better adapted to live in an environment. These organisms are able to survive and pass on their characteristics to their offsprings.
The red colour of the male cardinal's was selected by natural selection and hence this colour was abundant. If the females choose some other criteria for mating with males, then natural selection will no longer favor the red colour and hence there will be a decrease in the variations of red coloiur.
