Answer:
C) polarity
Explanation:
The polar nature of water molecules allows it to dissolve like molecules, such molecules are also polar.
- In water molecules hydrogen bonds provides a special dipole - dipole attraction.
- Here, the hydrogen atom is directly joined to a highly electronegative atom(oxygen, nitrogen or fluorine).
- This leads to a charge separation in which the hydrogen atom has net positive charge and the electronegative one has negative charge.
- This makes the molecule of water polar.
- By this property water easily attracts oppositely charged portions of another substance and then pull them into solution.
This property of water is polarity of water.
Answer:
a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body
so it is like a cell that works in the body but its a (organelles) in side the cell working in it like it is the cell in side the body
C. renewable resources replenish within our lifetime
Answer:
In the field of biology, karyotype can be described as the complete array of chromosomes that an individual possesses.
To use karyotype for determining the genetic disorders, a person must have knowledge about the normal karyotype so that the defected karyotype can be detected by comparison from the normal karyotype. The deletions, insertions can easily be recognized by such a manner.
Answer:
Specialization can be described as a process by which each cell of the body tends to specialize and perform a certain important function for the body.
Although, cells of the body might have a different structure and function, yet they all carry the same chromosomes and the same DNA. However, the expression of genes is what controls the functioning of each cell. The genes which might be expressed in one cell might be repressed in the other type of cell. Hence, this is the differentiation process which allows each cell to perform a unique function.
