Answer
Lamarckism, a theory of evolution based on the principle that physical changes in organisms during their lifetime—such as greater development of an organ or a part through increased use—could be transmitted to their offspring.
Lamarck believed that the stretching elongated the giraffe's neck, which became a useful characteristic and was passed onto future generations. This resulted in the length of the giraffe's neck increasing over time. It is now commonly accepted that Lamarck's ideas were wrong.
Answer:
The correct answer is "photorespiration".
Explanation:
Photorespiration is a process in plants, where molecular oxygen is taken in a light-dependent manner. Photorespiration is often considered a wasteful pathway because it competes with the Calvin cycle, which is much more efficient. In C3 plants the conservation of water promotes photorespiration. This occurs when the C3 plants close its stomata because the environment its too hot, or the carbon dioxide concentration drops to about 50 ppm.

<u>-The Retina</u>
<u></u>
The retina is a thin, transparent layer at the periphery of the eye's interior. Light enters the eye and is detected by specialized neural cells. The light is converted into an electrical impulse, by photosensitive rods and cones. This impulse is transmitted and interpreted by the central nervous system or CNS.
Further Explanation:
The nervous system is subdivided into; the central nervous system (CNS), which includes the brain and spinal cord, within the vertebral column; and the peripheral nervous system, which includes nerves that branch into the rest of the body from the brain and spinal cord. Nervous tissue responds to electrical impulses, allowing for communication between different regions of the body.
The peripheral nervous system is further divided into the somatic nervous system responsible for carrying out sensory and motor information between the peripheral nervous system- including sensory organs like the eyes; and central nervous system;

No bc Mitochondria are rod-shaped organelles that can be considered the power generators of the cell, converting oxygen and nutrients into adenosine triphosphate (ATP<span>). ATP is the chemical energy "currency" of the cell that powers the cell's metabolic activities. This process is called </span>aerobic respiration<span> and is the reason animals breathe oxygen. Without mitochondria (singular, mitochondrion), higher animals would likely not exist because their cells would only be able to obtain energy from anaerobic respiration (in the absence of oxygen), a process much less efficient than aerobic respiration. In fact, mitochondria enable cells to produce 15 times more ATP than they could otherwise, and complex animals, like humans, need large amounts of energy in order to survive.
