A. IS WHAT I WOULD CHOOSE
Answer:
The DNA is more closer to bacteria.
Explanation:
Mitochondria and chloroplast are considered as semi-autonomous organelle because they contain their own genetic material. The mitochondria and chloroplast evolution can be explained by the endosymbiont theory.
The DNA of mitochondria and chloroplast are more closely related to bacterial chromosome rather than eukaryotic chromosome. Both the organelle and bacterial DNA are double stranded and their translation can be inhibited by the chloramphenicol. Some of their replicating enzymes also show similar characteristics.
Thus, the DNA is more closer to bacteria.
The right answer is to perform photosynthesis (more precisely to convert ADP to ATP by ATP synthase).
Light comes to us in the form of photons. These photons have a different energy potential depending on their wavelength.
When a pigment picks up a photon corresponding to its absorption capacity, one of its electrons goes into the excited state. This energy can be transmitted in 3 ways: either by spreading it in the form of photon or heat; both ways lose energy. The third is to transmit resonance energy and there is almost no loss of energy.
A photosystem consists of a reaction center and a collector antenna to optimize the absorption of photons triggering photochemical reactions in order to operate the ATP synthase to produce ATP in the presence of a hydrogen gradient.
Answer:
Genetic drift is simply a change in the frequency of alleles in a population.
Like shown in the comic A, there are different genes present on chromosomes. All of these genes are made up of a pair of alleles. These alleles determine the genotype and the resulting phenotype of an organism.
If none of the alleles is favored by the environment, then a population will have equal no.of all the variant forms of a trait. Like shown in the comic B, both the green and the grey animals are favored equally.
But if natural selection occurs and one form of the allele variant is favored, then a genetic drift will occur. Most of the organisms will have the alleles which are favored by the environment. Like shown in Comic C, where the grey alleles are favored more than the green alleles.
Answer: The correct answer is peripheral
Explanation:
The Peripheral nervous system consists of the following:
- sensory neurons, which leads all parts of the body to the central nervous system
- motor neurons that runs the central nervous system to all parts of the body.
Thus, Peripheral nervous system is the answer
