Answer:
D diffusion across a membrane
Explanation:
Based on whether or not energy input is required, there are two types of processes viz: passive and active. Passive processes are those that do not require energy input in form of ATP while active processes require energy input to occur.
An example of passive process is DIFFUSION, which is the movement of molecules from a region of high concentration to a region of low concentration across a membrane. Diffusion is passive i.e does not require energy, because movement occurs down a concentration gradient.
Other processes in the options like cell division, DNA replication and protein synthesis all require energy input to occur.
If science is to be defined at,
science is a systematized body of knowledge. Science is where the organized set
of facts were obtained and is used as a tool, model or paradigm to gather such
evidential data. Science is not a fact but an existential body in which comprises
the study of the anatomy and physiology of a certain object by the means of
observation, hypothesis, experimentation, interpretation and conclusion of the
gathered facts. Or what others would describe the scientific process.

Answer:
The Mendelian principles of inheritance ARE APPLIED IN HUMANS. Both plants and animalls posseses two alleles (forms) of each gene, and are inherited in Mendelian ways. Some genetic diseases are Mendelian diseases and are inherited according to Mendel laws, those are the diseases caused BY A SINGLE GENE. However, there are multigenic diseases (that involves more than one gene), multifactorial diseases (which involves several genes and environmental factors), and chromosomic diseases (like 21 trisomy) and all of these does not follow the Mendel laws.
