All of the following statements are true. Decide which of the examples of molecular biology give evidence for evolution. Check a
ll of the boxes that apply. 1 HOX genes are very similar in all animals.
2 Bug wings and bat wings are both used for flying.
3 Many species share much the same DNA.
4 Plant and animal cells have almost all of the same structures.
4 Plant and animal cells have almost all of the same structures.
Explanation:
Evolution corresponds to the process of modification and adaptation of species over time. The current diversity and genetic similarity of living beings is the result of processes of transformation and adaptation of species to various environments, constituting biological evolution. As evidence of this evolution, we can mention:
HOX genes are very similar in all animals: Hox genes encode transcription factors that define cellular identities along the major and minor axes of the body. Its coordinated expression in space and time is fundamental for embryonic modeling. These genes control the development and positional differentiation of cells in the embryo, and their disposition along the chromosome collinear to the parts of the embryo they will regulate. They are present in many different animals representing a huge source of evolutionary change.
Many species share much the same DNA: All living things have DNA molecules that encode all genetic information. Among living things there are similarities and sharing of parts of DNA. This is strong evidence of species evolution. An example of this is the similarity between humans and chimpanzees.
Plant and animal cells have almost all of the same structures: Although there are some differences, plant and animal cells share almost all cell structures. This is a strong indication of how life has evolved on our planet.
<span>The answer is If ducks bark then cats fly. T</span>he converse of the statement If cat fly then ducks bark is If ducks bark then cats fly. <span>The converse of A implies B is B implies A.</span>
The scientist will add up the mass of the protons and mass
of the neutrons to come up with the approximate mass of atom because protons
and neutrons is what consist of the atoms. Therefore, in order to have the approximate
mass of an atom, adding the mass of protons and neutrons will give the result.
<em>A team of astronomers discovers a new planet with water. They notice that the process of evaporation does not seem to be working on this planet. Which statement best explains the state of the water cycle on this newly discovered planet?</em>
<em></em>
<em>The water is trapped as water vapor in the atmosphere and clouds.</em>
<span>No, it does not mean that the interpretation or design of the first experiment was wrong. What it could mean is that using unboiled water or the lack of paraffin was not the catalyst that caused the carbon dioxide to be produced.</span>
