I believe the answer is B. When a DNA sequence changes, it is mutated
Answer:
Non-covalent interactions.
Explanation:
DNA is present as genetic material in all the living organism except some viruses. DNA also perform important other functions - code for proteins, used as a source of energy.
The DA binds with protein to perform their functions. These proteins may acts as activator for DNA. The proteins binds in the non covalent interactions ( ionic bonding, hydrogen bonding, vanderwalls and hydrophobic interaction) so that proteins may easily detach from the proteins. These interactions helps in the attachment and easily detachment of proteins from DNA.
Thus, the correct answer is non-covalent interaction.
Answer:
Environmental impacts of particles, such as dust and smoke, released from livestock production - impair the visibility, can lead to acid rain, degrade the ecosystem
Environmental impacts of greenhouse gases released from livestock production - increase in atmospheric temperature
Explanation:
Environmental impacts of particles, such as dust and smoke, released from livestock production -
Release of particles such as dust and smoke is referred to as particulate pollution. These particle makes the air unfit for .breathing. If humans inhale it, it will adversely affect the heart and lungs.
These particle impair the visibility, can lead to acid rain, degrade the ecosystem etc.
Environmental impacts of greenhouse gases released from livestock production -
Green house gases will lead to increase in atmospheric temperature
The answer would be a. cancer cells become invasive and grow into a body tissue. Apoptosis is a programmed cell death that certain cells undergo in order to protect the organism. However, sometimes these cells can avoid apoptosis and do not respond to signals to stop dividing (known as uncontrolled cell division); this results in a mass of extra cells (tumor) and that's how cancer happens. Hope this made sense :)
