Antibiotics typically work as competitive enzyme inhibitors, they bind to enzymes and prevent them for being able to caring out certain metabolic processes. Antibiotics will effect only certain types of enzymes and typically humans may not produce these enzymes meaning it won’t have an effect on our cells but will kill bacteria. The thing is though we have “good” bacteria in our body that is also killed by antibiotics which in turn cause problems with digestion and other bodily processes. If you want an example of what an antibiotic does, it will prevent an enzyme in the bacteria from producing a membrane and it becomes easier for our bodies to attack the cell, white blood cells have an easier time killing the cell after the enzyme is inhibited. Also this is not to say that all antibiotics don’t affect human cells they may affect them slightly but typically bacteria is what’s killed
Answer: This is because all of the cells in our bodies start from a single fertilized egg. With few exceptions, all cells in a person's body have the same DNA and genes. As cells divide and grow different genes are expressed, resulting in different cell types.
Jerry is using the mindfulness technique.
Mindfulness is a psychological process which involves the focus of one's attention to experiences of the present moment. This process involves meditative techniques and it has been used by clinical psychologists to help people deal with some psychological conditions. Mindfulness has been used to alleviate symptoms of depression, stress and anxiety.
Specifically for stress, psychologists use the mindfulness-based stress reduction program which combines mindfulness, meditation, yoga and body awareness practices.
Answer:
Ribosomes are produced by the nucleus. Specifically, the nucleolus.
Explanation:
<span>Organisms that have ventilation systems will draw in air (or
water) that is rich in oxygen and will draw out air that has carbon dioxide. This
is essential for a multicellular organism to thrive because carbon dioxide is
harmful for an organism since carbon dioxide (CO2) is a waste product. Such is
the system that contain veins, capillaries and arteries. On the other hand, organisms
that don’t have ventilation system, can survive without it because they are
single-celled and the path for the nutrients and needed oxygen is so short that
they can efficiently exchange gases at the surface.</span>
