First, it is necessary that this scientist decide on what point of the Cretaceous period he wants to study. Among several points he may want to study the evolution of microorganisms of that time, the life of a dinosaur species, or the evolution of dinosaurs, the flora that was established during this period, among others. This is the phase of the scientific method called Observation.
After that, he must enter the phase called "Elaboration of hypotheses" where he will raise questions about the point he decided to study. "How many flower species existed in that period?", "How many of these flowers can we observe today?" among others.
After that, he will enter the phase called "Experimentation", where he will establish a type of experiment and all the experimental factors and variables that will allow the hypotheses to be answered.
After the experiment he will collect the data that will be analyzed and that will give results that will answer the hypotheses previously established. This is the phase called "Analysis of the results".
At that moment, he will be able to reach the last phase of the scientific method, the phase called "conclusion", where he will show the conclusions that the experiment allowed to be established.
It takes the muscle time to act once it receives a response from the nerves. It also takes time for the electric impulse to pass between gaps in the nerves (synapses).<span />
The correct answer is (c.) unicellular eukaryotes. Unicellular eukaryotes apply to most protists. Protists are grouping of eukaryotic cells that do not form any natural group. These eukaryotes include the Golgi apparatus and mitochondria, and for plants they include chloroplasts.
Answer:
Explanation:
Deciduous and Coniferous trees are both Woody plants and can both be found in the forest, but there are significant differences between them including-
1) The leaves of deciduous trees change color and are shed seasonally while the needles of Coniferous trees are not lost seasonally, neither do they turn pale
2) Deciduous trees are flowering plants and so they bear their seeds in fruits while Coniferous trees are gymnosperms and so bear their seeds in cones.
3) Coniferous trees possess needles in lieu of leaves while deciduous trees possess broad leaves
4) Examples of Coniferous trees are firs, junipers, redwoods, spruces, and pines etc. while examples of deciduous trees are oak, maple, and elm etc.
Lysozymes is the correct answer.
