Answer: The correct answer for the fill in the blank is- May be placed in the Plantae kingdom.
An organism that produces food by photosynthesis can belong to three kingdoms that are Monera ( example- cynobacteria) , Protista ( example- algae) and Plantae ( example- green plants).
Thus, it is not necessary that the organism must be placed in Plantae kingdom as it may belong to any of these three.
Organisms belonging to Animalia kingdom do not perform photosynthesis.
Thus, second option is the right answer.
The tryptophan operon is a repressible operon meaning that it is active when there's less TRP available. Therefore, to control the TRP operon when tryptophan is available, the tryptophan molecule must bind to the TRP repressor.
Answer:
I am pretty sure that the answer is A.
Explanation:
Protein kinases regulate the cell cycle by giving the "go-ahead" or "stop" signal at checkpoints in the cycle. A mutation/disruption in the protein kinases can result in it not doing its job properly. As a result, it can give the 'go-ahead' signal to all cells (mutated or not) to continue through the cell cycle. A distrupted kinase will infleunce the enviornment for a cancer cell as the cancer cell can continue to divide continuously.
I do not think the answer is D because G-couped receptirs are not involed in the regulation of the cell cycle. Additionally, I do not think the answer is C since the production of cAMP (a secondary messgenger amplifies transduction signals; this doesn't have anything to do with cancer?) Finally, between A and B I know that a direct result of cancer is due to a distruption in either protien kinases or growth factors (not in the answer choices). Since one of the factors that leads to cancer is present in answer choice A, I think that is the one. However, this is just my reasoning, I am not 100% sure!
Answer:
B
Explanation:
results don't always support a hypothesis in an experiment
success in an experiment doesn't necessarily represent your grade
a good experiment will achieve the same results when repeated
Answer:
Derived traits shared among the species or other groups in a dataset are key to helping us build trees. As shown above, shared derived traits tend to form nested patterns that provide information about when branching events occurred in the evolution of the species.
