Answer:
Make an observation.
Ask a question.
Form a hypothesis, or testable explanation.
Make a prediction based on the hypothesis.
Test the prediction.
Iterate: use the results to make new hypotheses or predictions.
Note: Question is Incomplete i have added full question in picture format. And marked correct answers.
Answer:
This question is about antibiotics resistance development in bacteria over time. Resistance develop only when we overuse these antibiotics. Resistance development in bacteria lead to their exponential growth resulting in more infections.
Also See attachment for full question and answer.
The true statements are:
A. Because the population grew more rapidly after time point C, the bacteria must have acquired a second drug- resistance mutation.
C. Bacteria that acquired a mutation that conferred drug- resistance had a growth advantage over non-resistant bacteria.
D. Between time points C and D, drug-resistant bacteria were reproducing faster than non- drug resistant bacteria were dying.
The central nervous system controls the majority of the body and mind. This is easily done as it's comprised of the spinal cord and the brain.
If the central nervous system is damaged, it typically causes terrifying results such as paralyzed below the waist or anywhere for that matter.
Therefore, the central nervous system's function is to control the majority of the body as well as the mind.
Hope this helps!
Answer:
Cyclins are the regulatory subunits of holoenzyme CDK complexes that control progression through cell-cycle checkpoints by phosphorylating and inactivating target substrates. Cyclins drive the events of the cell cycle by partnering with a family of enzymes called the cyclin-dependent kinases (Cdks).
Kinases are a type of enzyme (a protein that speeds up chemical reactions in the body) that adds chemicals called phosphates to other molecules, such as sugars or proteins. This may cause other molecules in the cell to become either active or inactive. Kinases are a part of many cell processes.
Telomeres are DNA-protein structures that form protective caps at the end of eukaryotic chromosomes. They constitute the safeguards of chromosome degradation and are responsible for maintaining genomic integrity.
The key difference between cyclins and kinases is that cyclins are regulatory proteins that have no enzymatic function in the cell cycle, while kinases are catalytic proteins that have an enzymatic function in the cell cycle.
Hope this helps!! Im taking bio right now and its very hard
