Answer:
All the statements are true and the correct option is;
D. All of these are true
Explanation:
Ecosystems change over time. ... Sudden disruptions such as volcanoes, floods, or fires can affect which species will thrive in an environment. Other disruptions are caused by human activities
An ecosystem ecosystem is an area where a community living (biotic) and non living (abiotic) things such as plants, animals, other organisms, landscape, natural sources and weather interact to create an apparently sustainable system
An ecosystem undergoes several changes over time due to environmental disturbance which results in the variation of the ecosystem's structure and change rate due to the natural disturbance and/or human activity
Therefore all the statements are true.
Answer: Ras activity would be significantly slower in its response to extracellular signals.
Explanation:
• GTPase acts as a catalyst in converting RasGTP (active state) to RasGDP (inactive state)
• A mutant lacking the GTPase activating protein cannot activate GTPase so thee will nit be any functional GTPase
• if GTPase is not present then RasGTP may be expdessed for longer periods of time and there will be a lag until it eventually switches "off)
The electron transport chain is part of the overall processes of cellular respiration and photosynthesis. The solution is A.
Answer: Climate is the long-term average of weather, typically averaged over a period of 30 years. Some of the meteorological variables that are commonly measured are temperature, humidity, atmospheric pressure, wind, and precipitation.
Explanation:
Answer:
NADH
Explanation:
Electron carriers such as NADH produced during glycolysis and the Krebs cycle pass their electrons to the electron transport chain, which results in synthesis of a lot of ATP.
