Conclusions

Answer:

100 units

Explanation:

The parent cell holds 200 units of DNA. During the process of cell division, this amount is distributed between the resulting daughter cells, with each cell obtaining half of the DNA present in the original cell.

As mitosis yields two daughter cells, each one will receive 100 units of DNA.

Initially, the scientist needs to determine the specific point in the Cretaceous period he wishes to investigate. This could involve studying the development of microorganisms from that era, the life cycle of a certain dinosaur species, or the evolution of dinosaurs, as well as the flora associated with that epoch, among other topics. This is referred to as the Observation phase of the scientific method.

Next, he will enter the phase known as "Hypothesis formulation" where he will pose inquiries relevant to his chosen study area. Questions might include, "How many flower types existed during that time?" and "Which of these flowers still exist today?" and so on.

Following this, he will proceed to the "Experimentation phase," where he will set up an experiment along with determining factors and variables crucial for answering the proposed hypotheses.

After conducting the experiment, data will be collected for analysis to generate results that address the previously established hypotheses. This step is termed "Data analysis."

Finally, he will reach the last step of the scientific method called "Conclusions," during which he will share the findings derived from the experiments.

Answer:

d. One additional neutron

Explanation:

Phosphorus-32, a radioactive variant of phosphorus, possesses 15 protons and 17 neutrons.

Conversely, Phosphorus-31, the most prevalent isotope of phosphorus, contains 15 protons and 16 neutrons.

This indicates that one isotope has one more neutron than the other.

Answer:

Earth qualifies as an inner planet.

Earth has a greater density compared to Jupiter.

Jupiter is predominantly gaseous.
