objects are brought into focus on the retina by changes in the curvature and thickness of the
Answers
Objects are brought into focus on the retina by changes in the curvature and thickness of the lens.
What is eye lens?The lens basically directs light rays onto the retina. The lens is clear and replaceable if necessary. As we age, our lenses deteriorate, necessitating the use of reading glasses.
The lens is normally clear and is located behind the iris. The pupil directs light to the lens.
Small muscles attached to the lens can cause the lens to change shape, allowing the eyes to focus on objects that are close or far away.
Light bends (refracts) and focuses on the retina at the back of the eye as it passes through the lens.
The lens's thickness and curvature can be adjusted to focus on objects at various distances and ensure that the image is as clear as possible (this process is known as accommodation).
Thus, eye lens helps to focus the object.

Neural impulses are transmitted to bipolar cells when light energy enters the eye and triggers ________ in the rods and cones.
Answers
Neural impulses are transmitted to bipolar cells when light energy enters the eye and triggers CHEMICAL CHANGES in the rods and cones. This process is known as phototransduction.
Phototransduction refers to the process by which photoreceptors convert light into electrical signals.
Photoreceptors (i.e., rod and cone cells) are specialized cells in the retina of the eye which are capable of converting light into electrical signals and thus trigger different physiological processes.
Phototransduction is triggered by the activation of signaling proteins, that open or close ion membrane channels in photoreceptor cells.

During photosynthesis, plants produce _____________ and oxygen from the _____________________________ of solar energy, water, and carbon dioxide
Answers
Answer:
During photosynthesis, plants produce glucose from simple inorganic molecules - carbon dioxide and water - using light.
Explanation:
Most life on Earth depends on photosynthesis.The process is carried out by plants, algae, and some types of bacteria, which capture energy from sunlight to produce oxygen (O2) and chemical energy stored in glucose (a sugar). Herbivores then obtain this energy by eating plants, and carnivores obtain it by eating herbivores.
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.
