Answer:
Grain size, sorting and shape of particles in sediment or rock can influence how much empty space is available to store water (porosity) and the ability of groundwater to move through the material (permeability). Aquifers are water-bearing formations with good porosity and permeability and are important groundwater resources.
Explanation:
Answer:
Transcription is the synthesis of RNA from the DNA. It is further divided into three steps:
Initiation: In this step at first, there is binding of RNA polymerase to the group of transcription factors, it binds at the promoter. It is followed by unwinding of DNA double helix, and then the synthesis of RNA starts.
Elongation: The RNA polymerase extends across the DNA template, it adds the base pairs in 5' to 3' direction. In the same step proofreading of RNA is done to eliminate the errors in synthesis.
Termination: In this step RNA polymerase detaches, at certain stop signals, adding of further base pairs is also terminated by RNA polymerase. The newly synthesized transcript of RNA is released.
<u><em>Answer: Climate change is a long-term shift in global or regional climate patterns. Often climate change refers specifically to the rise in global temperatures from the mid-20th century to present,natural accidents and humans, can cause changes in Earth's energy balance, including: Variations in the sun's energy reaching Earth. Changes in the reflectivity of Earth's atmosphere and surface. Changes in the greenhouse effect, which affects the amount of heat retained by Earth's atmosphere and Volcanic eruptions can affect climate change, First, they release the greenhouse gas carbon dioxide, contributing to warming of the atmosphere. But the effect is very small. Emissions from volcanoes since 1750 are thought to be at least 100 times smaller than those from fossil fuel burning.</em></u>

Answer:
a) the pyrimidine ring is assembled before being bonded to the ribose phosphate, whereas the purine ring is bonded to the ribose phosphate as it is formed
Explanation:
There are two ways for the synthesis of purines and pyrimidines:
- de novo synthesis-from basic simple units
- "recycling" synthesis-reuse of metabolites
Purines are synthesized directly on ribose sugar, in segments.
Pyrimidines are attached to the ribose after the synthesis of the base.
The correct ordering of the steps in scientific research is given below:
- Research question
- Hypothesis
- Background research
- Controlled experiment
- Data collection
- Data analysis
- Conclusion
<h3>What are the steps in scientific research?</h3>
The steps in scientific research refer to the steps or procedures that are followed by scientists in making scientific discoveries that explain observed phenomena.
The steps in scientific research are as follows:
- Research question - this is the question that a scientist seeks to answer based on his/her observations
- Hypothesis - statements made by scientists to explain their observations
- Background research - research is done to find support for or against the hypothesis.
- Controlled experiment - tests carried out to disprove or prove the hypothesis
- Data collection
- Data analysis
- Conclusion
