Answer: Conclusion
Explanation:
Scientific method can be defined as a detailed plan for conducting research in a particular scientific domain. This is used to give scientific explanation for natural phenomena. In scientific method a hypothesis is created, observation is made, experimentation is conducted and then finally a conclusion is made to address the hypothesis.
Therefore, after the research is completed the conclusion is made by analyzing all the facts related to the literature and results of the experiments.
First let me say this, i may be wrong. I think it would change over time because first of all the sandstone has different densities. Different kinds off rocks erode and get broken down by the wind at different rates. If its density is higher, it will take longer to erode
Mammalian fertilization comprises sperm migration through the female reproductive tract, biochemical and morphological changes to sperm, and sperm-egg interaction in the oviduct. Recent gene knockout approaches in mice have revealed that many factors previously considered important for fertilization are largely dispensable, or if they are essential, they have an unexpected function. These results indicate that what has been observed in in vitro fertilization (IVF) differs significantly from what occurs during “physiological” fertilization. This Review focuses on the advantages of studying fertilization using gene-manipulated animals and highlights an emerging molecular mechanism of mammalian fertilization.
I believe its D. response neuron.
Hope this helps!
