In the start of the light cycle, light-dependent reactions harness energy from the sun in order to create chemical bonds. These bonds are known as ATP and NADPH. These are the molecules that carry energy which are made in the stroma. The stroma is where the Calvin cycle takes place.
Answer:
B) integral proteins is your answer to the question.
A neuron enters hyperpolarization when there's an efflux of the potassium ions and the influx of chlorine ions. This moving out of positively charged cations and moving in of negatively charged anions makes the neuron enter a state of negative membrane potential. If a hyperpolarized neuron is stimulated by an oncomming action potential, it fails to get excited. This is because the neuron has its potassium ion channel inactivated by the negative potential. The potassium ion channel can only be activated when the potassium ions slowly leak inside to neuron to make it enter the state of resting membrane potential.
Answer:
B. First 200 feet
Explanation:
The first 200 feet deep zone of the ocean is termed as Photic Zone of the ocean because this zone receives sufficient quantities of light so that the phytoplanktons that are found in this are become enable for Photosynthesis. This zone is critically important because we know that phytoplanktons are the primary producers in oceans and the food web of the ocean starts with these phytoplanktons. This zone is considered to be the area of highest net primary productivity.
The eye spot and the chloroplasts work together to help the euglena survive because the eye spot senses the light and the dark. Since euglena need to do photosynthesis in which uses light energy to make usable energy, to get food, the eye spot will tell the euglena where to move in order for it to be able to do photosynthesis.
