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.
I would say Satellites. Satellites are the only thing here I see can measure things globally, the rest is more regional.
Answer:
With respect to the overwhelming similarity in behavior between males and females, 22 PAIRS of chromosomes are unisex (seen in both males and females)
Explanation:
Both male and female have 22 pairs of chromosomes which are called <em>Autosomes </em>with the last pair of sex chromosome which might either be XY in males while females with XX
Answer:
Star P is smaller than star Q
Explanation:
Absolute brightness is defined as brightness of a celestial object or star from a Standard distance usually taken as 10 parsecs from Earth. If one star is brighther than the other then there can be two variable playing major role given that they are at same distance –
a) composition of star and
b) Its size.
The larger the star, the more energy it will emit per second and hence more will be its absolute brightness.
Thus, star P is smaller than star Q
Answer:
The answer must be c: natural selection
Explanation:
All the other answers only help rappid food production which will lessen the use of natural selection over time.
