Consciousness refers to a state of awareness or alertness in which the subject is cognizant of one's environment and self. It allows people the awareness to selectively focus on certain stimuli.
The following statements does not describe a key feature of consciousness: C. Consciousness is permanent. In contrast, consciousness is not permanent because consciousness is dependent upon the functioning of the brain.

Explanation:
Proteins in the plasma membrane have several functions based on their components, location etc. For instance, if the protein transcends the entire plasma membrane it could be a transport protein, responsible for the import and export of certain molecules between the cell and the extracellular matrix (ECM). If the proteins are resting at the surface of the cell, facing the ECM, their role could be to detect components in the ECM, relaying a series of messages back to the nucleus so that the cell can ‘decide’ what it should do with this information (is it being told it should undergo apoptosis, should it begin to divide, should it migrate?). As well as this, it could be involved in the detection of foreign bodies such as pathogens. This is an extremely job for these proteins because if the cell does come in contact with a pathogen, the cell can use these proteins to engulf the pathogen and through a series of steps, present the antigen on their major histocompatibility complexes (either 1 or 2 depending on the cell type) or HLA’s for human cells. Thus it can be concluded that protein functions vary widely in the plasma membrane and due to the vast number of proteins that can be found there, it’s difficult to narrow down the exact main of functions of all these proteins put together.

Answer:

Explanation:
Tay–Sachs disease is an autosomal recessive disorder. The possible genotypes and phenotypes are:
- TT = normal
- Tt = carrier
- tt = Tay-Sachs disease
I will use <em>p </em>to call the frequency of the dominant <em>T</em> allele, and <em>q</em> the frequency of the recessive <em>t</em> allele.
If the population is in equilibrium, the frequency of the tt genotype is q².
The frequency of the Tt genotype is 2pq.
The Tay–Sachs carrier frequency will be 0.033
