Answer:
D. It goes through incomplete metamorphosis.
Explanation:
Damselflies do not hide away inside a pupa to transform into their adult form. Instead, they shed their skin several times as they grow, changing shape a little each time. <em><u>This process is called incomplete metamorphosis</u></em><em><u>.</u></em>

Answer:
Answer 1: The purpose of an experiment is to test a hypothesis.
Answer 2: Scientists commonly measure intensive properties to determine a substance's identity, whereas extensive properties convey information about the amount of the substance in a sample.
Answer 3: These principles are at work in the fundamental elements of the scientific method, such as formulating a hypothesis, designing an experiment to test the hypothesis, and collecting and interpreting data. In addition, more particular principles characteristic of specific scientific disciplines influence the methods of observation; the acquisition, storage, management, and sharing of data; the communication of scientific knowledge and information; and the training of younger scientists.
Answer 4: Data collection tools refer to the devices/instruments used to collect data, such as a paper questionnaire or computer-assisted interviewing system. Case Studies, Checklists, Interviews, Observation sometimes, and Surveys or Questionnaires are all tools used to collect data.
Answer 5: The purpose of an experiment is to test out your hypothesis. If your hypothesis is correct, then it is a theory that could work every single time the experiment has been performed by scientists.
Answer 6: ?
Answer 7: the first step toward teaching my students how to critically think about how they structured an argument or explanation was to implement the Claim, Evidence, Reasoning (CER) framework. While the premise behind CER isn’t anything new to the way science teachers already think, it provides an entirely different approach toward how students connect their experiences and previously learned content into something that is much more reflective of being scientifically literate.

Explanation:
1. As given, cell cycle is of 8.30 hours.
G1 phase= 4 hours;
S phase= 2 hours;
G2 phase = 2 hours;
M phase= 30 minutes.
2. Adding up each phase shows that the cell cycle is 8.5 hours long. As after 9 hours, the radio labeled cells would have passed through a full cycle ( from G-1 to m phase) and be in either S phase or G2- phase and none cell would have entered M Phase.
3. DNA synthesis occurs only in S-phase, so the incorporation of any radioactive nucleotide happens in S-phase only.
4. M phase, cell divide itself into two daughter cells.
