Answer:
The correct answer is- B) Cell walls are made primarily of peptidoglycan
Explanation:
There is a difference between the cell wall of bacteria, archaea, and eukarya. The cell wall of bacteria is primarily made up of peptidoglycan which contains two sugar N-acetylglucosamine and N-acetylmuramic acid while archaea contain two N-acetyltalosaminuronic acid (NAT) in place of N-acetylmuramic acid which is called pseudo-peptidoglycan.
Eukaryotic cell wall is also different from archaeal and bacterial cell wall and animals in eukaryotes do not have a cell wall. Therefore cell wall made up primarily of peptidoglycan will allow you to classify the organism as belonging to Bacteria but not Archaea or Eukarya.
The 4 factors affect evolution, according to Darwin’s Origin
of Species are;
Variation
Heritability
Competition
Differential survival
Variation ensures that
there is variability of population traits
on which selection pressures will apply.
Heritability means that the traits must be able to be passed down to offsprings through gametes.
Competition occurs when the individuals in the population compete for limited resources
Differential survival
occurs due to competition for resources
and other selection pressures. This result
to the survival of the strongest and weeding
out of the weak from the population.
Planets like, mercury, venus earth: they are in the increasing order of there masses. however this chain breaks at mars.
Planets like, jupiter, saturn, uranus, neptune are arranged in decreasing order of there masses.
