Answer:
The answer is D. I hope this was helpful!
Explanation:
Answer: Systematics
Explanation:
Systematics is the study of diversity of organisms including past and present and relationships among living things. Systematics as analytical approach, help us to understand the diversity and relatedness of both existing and extinct organisms. Systematics is also important in carrying out the conservation issues because, it attempts to explain the biodiversity which is related to different kinds of species and could be used in preservation and protect the endangered animals and plants.
Cytokinesis is part of M-phase, but not part of Mitosis. M-phase consists of nuclear division (mitosis) and cytoplasmic division (cytokinesis). And yes, telophase is part of mitosis, so it's in M-phase <span>too.

The photosynthesis occurs in the chloroplast, which contains chlorophyll - the green pigment in the plants.
Answer:
The correct selection of answers to the question: Identify the pieces of evidence describing the features of DNA that Watson and Crick used to determine the structure of DNA, would be:
C: The two chains are parallel, both running in a 5´ to 3´ direction
D: A purine base forms hydrogen bonds to pair with a pyrimidine base located on the opposite DNA strand. Specifically, A pairs with T, and C pairs with G.
E: The sugar-phosphate backbones of each DNA helix run antiparallel to one another
F: The diameter of the DNA doube helix is 2 nm, with each purine-pyrimidine base pair spanning an equivalent distance between the two chains.
Explanation:
Although Watson´s and Crick´s research, and model of the DNA helix, became the breakthrough for science, as it visually presented the now known characteristics of DNA, this research was possible due to the way that these two researchers used previous information found by other scientist on the molecule, to finally build their model. All of the options that were selected were part of the research of several scientis, including Mendel, Rosalin Franklin, Linus Pauling, Maurice Wilkins, Oswald Avery and many others, who worked on different aspects of specimens and their specific characteristics, and which led them to discover that organisms possessed DNA, that this was the unit of information that directed all functions in living cells and how this DNA helix was chemically built to understand how it worked, and why it worked the way it did.
