Answer:False
Explanation:Fossil fuels are the energy-rich substances
Answer:
For example, if the seeds that the bird needs to eat is bigger, over time it will adapt to get a bigger beak to eat the bigger seed. The birds that have adapted reproduce and soon more and more birds that have a bigger beak for the bigger seed are more common. If the type of food available changes than the bird will most likely adapt to eat that food.
Answer:
we need lymphatic system too,it is as important as circulatory system.
Explanation:
The lypmphatic system is part of the circulatory system, known as lymphatic veesels.
Answer:
The ATP synthase can be thought of as a type of molecule motor that is powered by the flow of __H+_ through the subunits and __down_ their concentration gradient.
Explanation:
There are two steps for the synthesis of carbohydrates in plants; one is light reaction and other is dark reaction. In light reaction the ATP and NADPH are produced from sunlight and these molecules are utilized for combining the carbon molecules in dark reaction.
Before we discuss chemiosmosis (Mechanism of ATP production) we should know that light reaction takes place in the thylakoid membrane of chloroplast. During the light reaction electrons removed from water are excited by light in photosystem I and photosystem II. These excited electron release the energy while traveling down the electron transport chain which is utilized to pump the H+ ions to stroma from lumen. This build a concentration difference of H+ ions across the membrane.
So when these H+ ions flow from stroma to lumen i.e. higher potential to lower potential they passes through ATP synthase complex. ATP synthase produces the ATP by the phosphorylation of ADP that why mechanism is also referred as Photophosphorylation.
<u>Answer:</u>
Integrator compares sensory information to a target value.
<u>Explanation:</u>
- Integrator is responsible for sending 'instructions to an effector' based on 'sensory information' which eventually give responses.
- These effectors execute the necessary changes required to adjust with the environment. Integrator act as the control centers.
- Integrators send signals to the effectors after comparing the variables or changes at a definite set point.
- However, its function mechanism is 'dependent on the feedback loop'.
