Organization of Cells
Biological organization exists at all levels in organisms. It can be seen at the smallest level, in the molecules that made up such things as DNA and proteins, to the largest level, in an organism such as a blue whale, the largest mammal on Earth. Similarly, single celled prokaryotes and eukaryotes show order in the way their cells are arranged. Single-celled organisms such as an amoeba are free-floating and independent-living. Their single-celled "bodies" are able to carry out all the processes of life, such as metabolism and respiration, without help from other cells. Some single-celled organisms, such as bacteria, can group together and form a biofilm. A biofilm is a large grouping of many bacteria that sticks to a surface and makes a protective coating over itself. Biofilms can show similarities to multicellular organisms. Division of labor is the process in which one group of cells does one job (such as making the "glue" that sticks the biofilm to the surface), while another group of cells does another job (such as taking in nutrients). Multicellular organisms carry out their life processes through division of labor. They have specialized cells that do specific jobs. However, biofilms are not considered multicellular organisms and are instead called colonial organisms. The difference between a multicellular organism and a colonial organism is that individual organisms from a colony or biofilm can, if separated, survive on their own, while cells from a multicellular organism (e.g., liver cells) cannot.

Answer:
A Hypothesis leading to knowledge should be put through severe tests, which includes the estimation of previous knowledge.
According to <em>confirmatory data analysis</em> systems, <em>"Confirmatory research"</em> helps to estimate with precision the value of a hypothesis or findings in a specific study or report, by estimating and evaluating previous studies on the subject matter; since that report doesn't provide evidence for existing hypothesis or evaluates previous existing results on the matter, neither states the absence of it, your professor might point out that <em>"Your report does not attempt to test a hypothesis"</em>. Thereby the answer would be a.)
Answer:
recessive
Explanation:
Alleles are the alternating forms of a gene and may be dominant or recessive. A recessive allele is the one that is not expressed in the presence of the dominant allele. Therefore, the expression of the recessive alleles occurs only in homozygous recessive genotype.
The recessive allele code for a non-functional or less functional protein which is not observed in the presence of fully functional protein encoded by a dominant allele in a heterozygous state. However, in homozygous recessive genotype, when the dominant allele is not present to code the functional protein, the non-functional proteins are apparent and the recessive allele is said to be expressed.
