Answer:
A
Explanation:
All living organisms ranging from unicellular prokaryotes to multicellular eukaryotes contain genetic material (DNA). This genetic material is usually found on structures called CHROMOSOMES. Although, the chromosomes are contained in the genome of all living organisms, there are differences.
The genetic material of the bacteria (a typical prokaryote) is a single DNA molecule that makes up its single circular chromosomal material, unlike in eukaryotes that contains double-stranded DNA molecules on linear chromosomes. This single circular chromosome of bacteria is found naked in a region of their cell called NUCLEOID, as they do not possess a membrane-bound nucleus that houses it (a unique characteristics of eukaryotes).
The mitochondrial and Chloroplast DNA mentioned in the other options are all components of eukaryotic cells. Bacteria, as a prokaryote does not contain this organnelles. Hence, they are not single replica.
Answer:
Membrane proteins perform a variety of functions vital to the survival of organisms: Membrane receptor proteins relay signals between the cell's internal and external environments. Transport proteins move molecules and ions across the membrane.
Explanation:
they help transport some substances through the membrane.
Answer;
Evolutionary psychologists; behavioral psychologists
Evolutionary psychologists look at the genetic tendencies that we share as a species, whereas behavioral psychologists explore human genetic differences.
Explanation;
-Evolutionary psychology is a theoretical approach to psychology that attempts to explain useful mental and psychological traits such as memory, perception, or language,as the functional products of natural selection. Evolutionary psychology is focused on how evolution has shaped the mind and behavior.
-Behaviorism is concerned with how environmental factors affect observable behavior. The behaviorist approach proposes two main processes whereby people learn from their environment: namely classical conditioning and operand conditioning.
