Answer:
Similarities among organisms lead scientists to relate organisms
Explanation:
Fossils found in sedimentary rock can be compared to one another and to living organisms to compare similarities and differences.
Answer:
conseving is important so that future generations of wildlife will have a better life
cleaning up is important because so that wildlife wont get traped in waste
chiming in is important because one perosn wont make a difference but as a group you can do more

Answer:
The way to find a codon is by arranging the sequence of nitrogenous bases of the mRNA in groups of three, the triplets. Once the codon is found, the anticodon corresponds to a complementary triplet to that codon.
Explanation:
Codon corresponds to a triplet of mRNA nitrogen bases encoding an amino acid. Anticodon is responsible for carrying amino acids to the ribosome, according to the information of the mRNA, and the sequence of its triple must be complementary to that of the codon mRNA.
If, for example, a codon of the mRNA is AUG, its anticodon of the tRNA must be UAC, that is, complementary. Then, for the indicated exercises:

To test his hypothesis, the student will have to design an experiment to measure the effects of <u>temperature on cellular growth</u>.
To test the effects of temperature on cellular growth the student will have to create an experiment containing the there kinds of variables:
- Dependent
- Independent
- Control
In this experiment, the control variable will be the kind of cells used, as well as the incubation methods being used. We identify these as the control variable given that they will remain constant.
The independent variable will be the Temperature at which we will place each cell being studied. The dependent variable, on the other hand, is by definition, what we seek to measure. In the case given it would correspond to the amount of cellular growth.
To test his theory of the effects of temperature on cellular growth, a student can design an experiment in which the control variable will be the cells themselves, the independent variable will be the Temperature, and the cellular growth can act as the dependent variable.
