The process of activating photoreceptors by altering the photopigments is known as PHOTOTRANSDUCTION. It involves the mechanism by which light can be converted into electrical signals.
Phototransduction refers to the mechanism by which light can be converted into electrical signals.
Visual phototransduction occurs in the part of the eye known as the retina, in specific cells called photoreceptors and ganglion cells.
Photoreceptor cells include rod cells and cone cells, which are sensitive to light.

Explain why carbon dioxide is constantly given off during the Krebs cycle.
Answer:
Hope it helps
Explanation:
mark me brainliest and follow me for more answers
Glycolysis and the citric acid cycle both produce carbon dioxide, which is a crucial byproduct (Krebs cycle). This oxidized carbon is a metabolic waste product that must finally be eliminated through transit to the lungs and subsequent exhalation into the environment.
What is the purpose of Krebs cycle?
Pyruvate is converted into three different products by the Krebs cycle: carbon dioxide, a little quantity of ATP, and the reduced molecules NADH and FADH.
Each acetyl group adds two carbon atoms to the citric acid cycle. On each cycle turn, two carbon dioxide molecules are emitted.
However, these do not include the identical carbon atoms that the acetyl group contributed on that turn of the circuit.
Therefore, carbon dioxide is constantly given off during the Krebs cycle.

Ovulation starts when the secretion of Luteinizing hormone (LH) peaks in females.
Ovulation is simply the release of eggs from the ovaries of females. It happens as a part of the menstrual cycles of the female gender.
The release of eggs from the ovary is triggered by an acute rise in the level of LH in females. LH in males stimulates the production of testosterone.

A submicroscopic virulent agent that infects animals, plants, bacteria etc. is called viruses. They are capable of copying inside host cells only. Viruses cause many diseases in animals and plants.
The correct discussion is:
Student A believes that viruses are not living organisms.
The student's statement can be explained as:
The virus is not capable of reproducing on its own without a host system. Therefore they cannot fit in the definition of a living organism. They just have a genetic material encapsulated in protein coats and do have defined cell structures, unlike prokaryotes and eukaryotes.Therefore, viruses are not contemplated to be living.

Which process occurs at location W? precipitation evaporation condensation transpiration.
Answer:
Precipitation
Explanation:
If it's the graph that I am thinking of, then it is precipitation. This is where raining occurs in he picture.
The biogeochemical cycle where the water circulates from the atmosphere to the Earth surface in a continuous motion is called the water or hydrological cycle.
The process that occurs at location W is:
Option A. Precipitation
The water cycle can be explained as:
The water cycle has four main components that are evaporation. condensation, precipitation and runoff.When an atmospheric substance falls on the ground in the form of rain, snow hails etc. are called precipitation.When the water from surfaces turns into vapours and moves upwards in the atmosphere is called evaporation.The vapours in clouds turn into water droplets ready to fall as rain or snow is called condensation.Transpiration is a plant function in which surplus water is exhaled from the stomata of the leaf.Therefore, the water cycle shows precipitation.

Outline what has to occur in the body for a reflex and a voluntary action to occur.
Answer:
For involuntary actions (reflexes) the information is first detected in the sensor and travels along sensory neurons to the spinal cord. Once the action potential reaches the spinal cord, the information is transmitted across the synapse to the motor neuron. for voluntary actions,
movements are commanded by the motor cortex, the zone of the cerebrum located behind the frontal lobe. The motor cortex sends a neural message that moves through the brain stem along the spinal cord and into the neural network to the muscle being commanded.

Mountain chains in northern Europe and West Africa match the Appalachian Mountains in terms of their ages and the sequences of rock layers that make them up. in 3-5 sentences analyze these observations and explain what conclusions can be drawn from them.
The above observation shows that the mountain chains in Northern Europe and West Africa are part of the Appalachian Mountains as a result of the same age, matching of rocks, etc
A mountain chain simply means a row of high mountain summits or a contiguous ridge of mountains within a larger mountain range.
The theory of plate tectonics establishes a co-relation with these mountain chains by understanding their movements. It was shown that Europe and Africa were part of the same landmass in the past. Due to the gradual movement of plates, both continents move apart.
