Answer; 
Alleles are passed from the parents’ sex chromosomes to the sex chromosomes in the offspring. 
Explanation; 
-Sex linked traits are traits that are carried by the sex chromosomes and inherited together. 
-Gene exists in alternative forms called alleles and each allele for a trait is inherited from each parent.
-Sex traits, like the other traits, are passed from parents to off spring through the process of sexual reproduction.
 
        
                    
             
        
        
        
Answer:
The skeletal muscles connect to the bones and work with connective tissue at the joints to allow for movement. The muscles connect to the nervous system and allow initiation of movement through nerve signals to and from the brain. The bones and muscles are supported by connective tissue, which plays an integral role in structural support.

Answer: 
 *Sensory adaptation* is the common adaptation in all three sense. Sensory adaptation is the process in which changes in the sensitivity of sensory receptors occur in relation to the stimulus. All senses are believed to experience sensory adaptation.
Explanation:
This adaptation is shared as well as used differently as explained below.
1) Hearing+balance :In terms of hearing, our ears adapt to loud sound as it hits the small bones located in the inner ear. The loud sound leads the inner ear bone/s to contract. This contraction causes the reduction or delay of transmission of sound vibrations to the inner ear. Detection of the vibrations follows. However, this process of auditory adaptation usually does not work very well with loud sounds that are sudden or instantaneous. Examples of these sounds are gun shots or explosions
2)Smell :Low concentrations of several chemicals present in the air can be detected by the sensory receptors in the nose. These chemicals that we quickly detect include those in perfumes or air fresheners
