Answer:
The polar head groups of phospholipids interact with water while the hydrophobic hydrocarbon tails are packed away from the water.
Explanation:
A phospholipid contains glycerol to which hydrocarbon tails are bonded. These hydrocarbon tails make the hydrophobic region of the phospholipids and are packed away from the water to make the inner core of the membranes. Glycerol of a phospholipid also has a phosphate group attached to its third carbon. The phosphate and glycerol moiety together make the hydrophilic head part of the phospholipid and interact with the surrounding water.
Answer:
A. I, II, III, and V only
Explanation:
In genetics, an allele refers to the specific form of a gene, which encodes traits. These alleles are usually in pairs in a diploid organism i.e. an organism with two sets of chromosomes. According to Gregor Mendel,
- An allele can either be DOMINANT when the allele masks the phenotypic expression of its allelic pair while the allele that is masked is said to be RECESSIVE.
- Two alleles can also be CO-DOMINANT when the two alleles are neither dominant or recessive over one another but are simultaneously expressed in that particular gene.
- Alleles can also be INCOMPLETELY DOMINANT when one allele is not completely dominant over the other, hence, forms a third intermediate phenotype when in combination with the second allele i.e. in an heterozygous state.
Based on this, an allele can be dominant (I), recessive (II), codominant (III), and incompletely dominant (V).

The correct answer is "i<span>t receives incoming sound information and directly stimulates the auditory nerve to transmit information to the brain."
Cochlear implants function to bypass the damaged cochlea due to sensorineural hearing loss (i.e. chronic noise exposure). Cochlear implants functions just like the hair cells and capture sound and transmit it via the vestibulocochlear nerve or the cranial nerve VIII and then to the temporal lobe in the auditory cortex.
