Answer:
The correct answer is "II. peroxisomes, I. mitochondria, and III. lysosomes".
Explanation:
The differences in organelles density are utilized for purification purposes, creating density gradients that helps to isolate each organelle separately. The correct order of organelles from most dense to least dense is: peroxisomes, mitochondria, and lysosomes. Peroxisomes have a density of around 1.19 g/ml, mitochondria of around 1.07 g/ml, and lysosomes of around 1.04 g/ml.

Explanation:
Cell membranes are barriers which protect and regulate the movement of substances in and out of the cells. It is a semi-permeable and selective structure.
In the passive transport system, substances move along a concentration gradient and it doesn't require energy. The examples of passive transports include; simple diffusion which transports carbon dioxide and oxygen, osmosis and facilitated diffusion which transports charged molecules like ions, sucrose etc.
In active transport, substances move against the concentration gradient. This requires energy. The two main types are: primary active transport, which uses direct metabolic energy e.g Na+/K+ pump, and the secondary active transport system which couples the transported molecules with another molecule moving along the gradient, example the Na+/glucose transporter.
Allowing a scientist to hide information from the public and other scientists has many consequences. By hiding findings, it can prohibit other scientists from using the findings to further advance the research process. It is crucial that findings are shared so advancements in things such as medicine, mental health, physical health, and all other sciences can progress to better help people. If, for example, a scientist found that there are links to cancer and sugar, withholding that information from the public would therefore prevent people from taking precautions against cancer.
I think the correct answer would be the third option. Environmental influences include family dynamics, neighborhood quality, and educational opportunities. These influences involve everything that surrounds an individual. The environment one is subjected to greatly affects the totality of that person may it be psychological, social, physical, behavior or attitude, beliefs and perception. For instance, if a child grow up in an environment that is healthy where relationships are nurtured and love and respect is present between members, then most likely this child would grow with great self esteem and would have the same characteristics as the people he lived with.
