Correct option A) None.
The male dwarf's father was of normal height; that is, homozygous recessive for achondroplasia. Consequently, the dwarf man of this exercise was heterozygous for the character (say Aa) because this condition is autosomal dominant.
He also has normal vision reason why he is X-NY and X-N which represents the X chromosome with the dominant N allele for normal vision. The woman is color blind and hence a homozygous recessive X-nX-n and of normal height.
Autosomal dominant helps to alleles harbored by any chromosome other than the sexual pair that show complete dominance over the recessive ones. Other diseases such as Huntington's disease, are autosomal dominant.

Answer:
The correct answer is B.changing muscle length
Explanation:
Isometric exercise involves the contraction of a particular muscle group without changing the length of the muscle and the affected joint does not move in the exercise. Isometric exercise helps in muscle strength because they are done in a single position without any movement.
This allows them to improve the strength of a particular position. Some of the isometric exercises are high plank, self-arm wrestling, forearm plank, low squat, etc. So isometric exercise strengthens muscles without changing the length of the muscle.
Producers, also known as autotrophs, make their own food. They make up the first level of every food chain. Autotrophs are usually plants or one-celled organisms. Nearly all autotrophs use a process called photosynthesis to create “food” (a nutrient called glucose) from sunlight, carbon dioxide, and water.
