Receptors in muscles provide the brain with information about body position and movement. The brain controls the contraction of skeletal muscle. The nervous system regulates the speed at which food moves through the digestive tract.Your muscular system is closely connected to the nervous system.
Answer:
a new fossils are constantly being discovered
Explanation:
Answer: Black allele has frequency of 0.14.
Red allele has frequency of 0.86.
The frequency of heterozygotes is 0.241
Explanation: <em>Hardy-Weinberg model </em>states the frequency of alleles in a population will stay in equilibrium as long as there are external influences. It is also used to determine alleles frequencies using the following equations:


p represents frequency of dominant allele;
q represents frequency of recessive allele;
2pq is frequency of heterozygotes;
For the frequency of red allele, which is dominant, we can use:




p = 0.86
For the black allele:



q = 0.14
Frequency of heterozygotes is
2pq = 2(0.86)(0.14)
2pq = 0.241
<u>Frequencies for a population of Muscovy ducks are </u><u>0.86 for red allele, 0.14 for black allele and 0.241 for heterozygote.</u>
Yeah they are and it’s because
