Answer:
Many scientists were skeptical of the endosymbiotic hypothesis because it didn't seem to fit into the theory of evolution as it was understood then. Between 1900 and 1950, biologists made many key discoveries in the field of genetics by focusing on small, random changes in DNA — mutations — that occur when a cell reproduces.
Explanation:
C would be the correct answer
Correct answer: D). DNA technology can increase genetic diversity by producing more variant alleles.
The genetic diversity can be increased by the mutation that creates new alleles in the population. The recombinant DNA technology enables the joining of DNA from the two or more than two sources that allow changing the genetic composition of the living organism. The genetic diversity helps the population to adapt to the changing environment.
Hence, the correct answer would be option D.
Answer:
It will be on the cytoplasmic side of the endoplasmic reticulum
Explanation:
The inner mitochondria protein called Adenine Nucleotide Translocator or ADP/ATP carrier protein, maintains the transport of ADP into the matrix of the mitochondria from the cytoplasm for ADP to be available for ATPase synthesis of ATP, from ADP and Pi(inorganic phosphate ion) during chemiosmosis of oxidative phosphorylation in the mitochondria.
The same carrier proetin also convey the synthesized ATPs back to the Cytoplasm for cellular utilization.
Therefore the ATP binding site should at the cytoplasmic side of the E.R, because the cytoplasm of the E.R is the site of deposits of synthesized ATP s, thus proximity of the ATP-binding site to it is needed.
Answer;
3. the two organisms belong to the same kingdom
Explanation;
-The classification of living things includes 7 levels, from the highest to lowest rank: kingdom, phylum, classes, order, families, genus, and species . The most basic classification of living things is kingdoms.
-The broadest classifications are by domain and kingdom; the most specific classification is by genus and species.
Therefore; if two organisms are in the same phylum, then it means they both belong to the same kingdom, because kingdom is the rank of classification higher than phylum.
