Answer:

C. Water molecules flow in both directions at the same rate.

Explanation:

The relative concentration of solutions indicates the direction of movement of water across the semi-permeable membrane. An isotonic solution is that which has the same osmolarity of a cell. As a result, there is no concentration gradient for water across the cell membrane. In this case, water molecules will move through the plasma membrane in both directions with the same rate. Thus, there will be no net movement of water into or out of the cell.

Dafna11 [192]

Dominance involves one allele masking another at the same locus whereas epistasis involves one locus masking a different locus.

Explanation:

Epistasis is a type of gene interaction in which one gene masks or modifies the expression of another gene at a distinct locus.

Dominance refers to the gene interaction in which one allele of a given gene masks the expression of another alllele of same gene.

The comparison of dominance and epistasis give the following  information:

  • Dominance  involves  allelic suppression while epistasis involves non-allelic suppression.
  • Dominance involves a single pair of alleles while epistasis involves two pairs of allele.
  • In dominance, the expression of recessive allele is suppressed while in epistasis, either recessive or dominant  non allele is suppressed.
  • The effect of dominance is due to the dominant allele while epistasis may be due to dominant or recessive allele.

erica [24]

Answer:

Eukaryotic and Prokaryotic cells are fundamentally different.

Explanation:

A prokaryotic cell is basically an entire organism that works within a single cell. Its genetic material is not in a nucleus.

A eukaryotic cell is part of an organism. This cell has its genetic material in the nucleus. In addition, it possesses organelles.

All cells are not the same because some, like the prokaryotic ones, make up an entire living organism. Others, like the eukaryotic cells, are part of much more complex living forms. Furthermore, each cell type within each category has unique functions.

An efficiency apartment can be compared to a prokariote. Prokariotes have everything they need in one cell. A mansion is more similar to a eukaryote. Every room of the mansion is important for the fully equipped mansion.

Homeostasis is maintained by which of the following organ systems in humans?
a_sh-v [17]

A. Multiple organ systems working together

Explanation:

All of the organ systems work together to maintain homeostasis in humans because each system does something different. For example, the circulatory system delivers oxygen rich blood to the bones and the bones create new blood cells. When one thing is wrong with one system, it affects all of the systems, like a disease. Another example of this would be the central nervous systems and endocrine working together to coordinate messages to the brain about the body's state while resting and exercising to maintain homeostasis.
