Answer:
The correct answer would be - complex eyes evolved in the gradual steps, each of which was fully functional and adaptive in improving visual acuity.
Explanation:
The natural selection of the complex traits such as the vertebrate eye (complex eye) are seems to be problematic, many biologist think that the complex eyes evolution is take place in gradual steps and each step of this evolution was adaptive and functional in improving the visual acuity.
The steps that were involved are like light sensitivity patch, a deepening hole or pit that help in sharp vision and many other random evolution steps.
Thus, the correct answer is- complex eyes evolved in the gradual steps, each step of this evolution was fully functional and adaptive that helps in improving visual acuity.
It’s a term for molecules present in organisms that are essential to one or more typically biological processes, e.g. cell division.
Answer:
The correct option is option C, nucleus
Explanation:
As the scenario described in the question, the medicine X functions on the DNA as it's characteristic shows that it is damaging the DNA. The DNA is present inside the nucleus of a cell. Hence, for a medicine to function on the DNA, the medicine must enter the nucleus of the cell as it is the location where the DNA is present.
Other options like, option D, is not correct because the process of conversion of mRNA into proteins takes place in the ribosomes and DNA is not present there.
Answer;
- Hydrogen peroxide
Explanation;
-Enzyme catalase is a protein enzyme present in most aerobic cells in animal tissues. Catalase is present in all body organs being especially concentrated in the liver & erythrocytes. The brain, heart, skeletal muscle contains only low amounts.
The substrate for the enzyme catalase is hydrogen peroxide. It catalyzes the decomposition of hydrogen peroxide to water and oxygen.
2H2O2 = 2H2O + O2
Answer:
Animals in the same order are similar evolutionarily, but are still very different species.
Explanation:
Animals in the same order have a common evolutionary ancestor that may give them similar traits, but the species can still be very different with morphologies.
