Science can be used to address societal issues and to inform policies. Hope I Helped :)
Answer:
Conclusion
Explanation:
When doing a science lab, the conclusion is the part at the end of the lab where you describe what you've learned and whether or not your hypothesis was supported by your results.
Answer:
a. It is a competitive inhibitor.
Explanation:
A competitive inhibitor competes with the substrate for the active site of the enzyme. Binding of the competitive inhibitor to the active site of enzyme forms enzyme-inhibitor complex and does not allow the substrate to bind to the enzyme. This inhibits the reaction. However, the competitive inhibition is overcome by increasing the concentration of substrate around the enzyme to facilitate its binding to the enzyme's active site.
According to the given information, malonic acid competes with succinate for the active site of enzyme succinate dehydrogenase and inhibits the reaction. This inhibition is overcome by increasing the succinate concentration around the enzyme. This makes malonic acid a competitive inhibitor to succinate dehydrogenase.
The correct answer is they are produced by cyanobacteria.
Stromatolites are being produced by cyanobacteria.
Stromatolites are termed as layered mounds, which have columns and also sheet like rocks which are originally formed with growth of layers.
Lichen stromatolites is a type of stromatolite which is formed by layered structures rocks and they are formed above water.
Answer: The organism that has the adaptations described that enable it to survive in the tundra is the POLAR BEAR.
Explanation:
ADAPTATION is defined as the process by which an organism becomes fitted to its environment thereby enabling the organism to live successfully and reproduce.
In any population, an organism is able to survive if it has features that help them to fit and compete successfully in that environment.
From the question, a typical example was given concerning the POLAR BEAR (Ursus maritimus) and it's best fitted environment which is the tundra.
The tundra is a type of biome that is treeless marshy vegetation which is composed mainly of dwarf shrubs. It's has a cold climate (Arctic region) with long icy winters and very short summer with an average temperature of 10°C.
Ursus maritimus has a variety of adaptations which enable it to survive in the tundra. These adaptations include:
--> The presence of a thick coat of insulated WHITE FUR: this helps it to survive the cold environment by acting as an effective insulator. The fur is also found at the base of its large paws with small bumps, which protects it against cold surfaces and provides its with a better grip of ice as it walks across it. It also gives it a concealing coloration making it unnoticed while it stalks its prey in the snow. These are the features that enables it survive the terrestrial environment if tundra.
--> it also has some aquatic adaptations which enables it to hunt it's favourite food which is seals. The presence of large front paws which are slightly webbed allows them swim for a long distance in search of food.
