Given what we know, we can confirm that the cell theory states that all cells come from preexisting cells despite the cells in a multicellular organism being so different from one another due to cellular differentiation.

<h3>What do we know about cellular differentiation?</h3>
  • Cellular differentiation involves the selective expression of DNA.
  • When only specific parts of the DNA sequence are expressed, and thus only specific proteins are formed, a cell can differentiate.
  • This allows the cells to specialize themselves despite all of them containing the same DNA.
  • Over time, this has allowed all cells, despite sharing a common origin, to become vastly different.

Therefore, given that cellular differentiation controls what genes of a cell are expressed in order to allow the cell to specialize itself into a specific cell type, this explains why even though all cells share a common origin, they can all be very distinct.

Which muscles do you control when exercising? cardiac muscles skeletal muscles involuntary muscles smooth muscles?
Mashutka [201]

While doing exercise, one can control skeletal muscles only.

The body has three kinds of muscles, that is, skeletal muscle, cardiac muscle, and smooth muscle. The skeletal muscles are linked with the bones of the skeleton, that is why these are under control and are known as voluntary muscles.

On the other hand, the smooth muscles like skeletal muscle can never be under control. These muscles helps in pushing substances, like blood or food through organs. The cardiac muscle is also an involuntary muscle, which is found only in the heart. These muscles helps in contraction of the heart and can never be controlled.

How do genetics (genetic predisposition) and the environment work together to cause substance abuse in individuals? What is the
vampirchik [111]

Answer: The drug abuse is influenced by the environment and exerts influence on the gene expressions.

Explanation:

The genetic make up of the person is decides, which genes will be expressed and develop a trait in an individual. But this genetic expression can be influenced by the environmental factors like food, exposure to sunlight, and others. This study which relate environment with the genetic make up is called epigenetics. No person is drug addict by birth but the consumption of drug can influence the genetic make up and traits in a abuser. So here, the environment is influencing the genetic basis of a abuser.
