Answer;
Endosymbiotic theory is important as it explains the origin of the chroloplast and mitochondria. It also explains the formation of the eukaryotic cells.
Explanation;
Endosymbiotic theory explains the origins of eukaryotic cell organelles such as mitochondria in animals and fungi and chloroplasts in plants.
Mitochondria and chloroplasts are believed to have developed from symbiotic bacteria, specifically alpha-proteobacteria and cyanobacteria, respectively.
Answer:
Ribose sugar
Explanation:
Ribose sugar is the 5 carbon sugar that is a structural component of RNA which is different from the sugar that is found in the DNA. In DNA deoxyribose sugar is present in which the 2' hydroxyl group is absent and is replaced by a hydrogen atom.
RNA is made up of nucleotide monomers which consists a ribose sugar, a phosphate group and a nitrogenous base attached to the sugar. In RNA in place of thymine nucleotide, another nucleotide uracil is present. Transcription is the process by which DNA is converted into RNA.
The new nucleotide adds towards 3' end of growing nucleotide by a phosphodiester bond. So the right answer is ribose sugar.
Answer:
A) the sexually reproducing species
Explanation:
Although we do not know how the change in temperature directly affects the bacteria species, we can say that the species that reproduces sexually are more likely to thrive because these species are also able to reproduce asexually. In other words, this species handle two mechanisms of reproduction
Unlike the species able to reproduce sexually (and asexually), the other species only reproduces asexually. Therefore, if the change in temperature affects asexual reproduction, the species that have both mechanisms will thrive using sexual reproduction, but the other species (not able to reproduce sexually) will not survive.
The correct answer is D. It kinda makes since although it could be B, I would go with D let me know if correct.
Answer:
C
Explanation:
<em>A person with garbled speech may have experienced damage to the frontal lobe portion of the brain.</em>
<u>This is because the left portion of the frontal lobe of the brain is an area that has been touted to be responsible for the control of speech in humans. Research in the past has shown that damage to that region of the brain affects the formation of spontaneous speech as well as motor speech control.</u>
Hence, garbled speech in someone that has experienced stroke can be attributed to damage to the frontal lobe.
Correct option: C.
