Answer:
Explanation:
The unicellular organisms basically classified into prokaryotes and eukaryotes. In case of bacteria the nucleus was completely absent but the replication and translation process were combined together. so there is no need of complexity. The genome is under control of one replication of origin i.e. the replication of DNA and translation for proteins synthesis takes place simultaneously and again no complexity. The organism is depend on these proteins and DNA for different purposes like fission, energy production etc.
If we think about Eukaryotes there is separate boundary for DNA and protein synthesis Nucleus and rest of cytoplasm with organelles. The complexity increases because of functional variations and functions occur at different times. So the whole genome replication is not needed every time and there are separate Origin of replications for segments of DNA (genes). Along with these there are non-functional DNA segments (introns functionally they won’t give proteins). To eliminate them there is a separate process after mRNA synthesis called post transcriptional modifications. After this protein synthesis takes place at cytoplasm. There is one more check point called post translation modification where protein modification (functional diversity) allocated. To adapt the changing environment, stress, reproduce and for any functions there is a wide diversity if we compare prokaryotes and eukaryotes.
When electromagnetic waves strike an obstacle, what usually happens is that part of the wave is absorbed by the obstacle, part is reflected back and part is transmitted through the material.
However, in case of a dark object; the dark object acts as a perfect absorber and absorbs all the electromagnetic waves.
So, the right answer is the diagram showing only absorption of the wave by the surface.
Answer:
Rapidly and Accurately
Explanation:
As an example, eukaryotic human DNA replicates at a rate of 50 nucleotides per second.
Replication occurs so quickly because multiple polymerases<em>, or think: enzyme+polymer=polymerase,</em> can synthesize<em>, or combine or fuse,</em> two new strands at the same time by using each untwined strand from the original DNA double helix as a guide.
DNA replication is so much faster than bacteria replication because it's extremely difficult to replicate DNA accurately, as well as copying molecules that tightly complexed with histones in nucleosomes, which work together to form chromatin, which is the material that chromosomes are composed of, and it's further composed of protein (histones), DNA, and RNA.
Therefore, the reason for human cells taking significantly less time to replicate its genome is <u>accuracy</u>.
One reason could be that they do not have most of the seven characteristics of life (reproduction, homeostasis, heredity, response to the environment, growth, cellular organization, and metabolism.)
<span>The correct option is this: THE HEART BEGINS BEATING.
A fertilized egg takes about 40 weeks to reach full maturity. At week 5, the developing fetus resemble a tadpole; at this stage, the circulatory system has begin to form and the tiny heart has started beating and the baby is the size of a sesame seed. By week 6, the heart beat of the baby can fully be detected through scan.</span>
