Lamarck is best known for his Theory of Inheritance of Acquired Characteristics: If an organism changes during life in order to adapt to its environment, those changes are passed on to its offspring. He said that change is made by what the organisms want or need. For example, Lamarck believed that elephants all used to have short trunks. When there was no food or water that they could reach with their short trunks, they stretched their trunks to reach the water and branches, and their offspring inherited long trunks. Lamarck also said that body parts that are not being used, such as the human appendix and little toes are gradually disappearing. Eventually, people will be born without these parts. Lamarck also believed that evolution happens according to a predetermined plan and that the results have already been decided. Lamarcks theory has been disproven and shows that acquired traits are not passed on to offspring.

Gathering information with your eyes is called visual
perception. Option “D” is considered the correct option. Under normal
circumstances light is received by the eye. This light is then broken down into
two parts and they are peripheral vision and central vision. The information
then gets transferred to the brain which is then analysed to extract the actual
information. This is place for getting the actual perception. This is how the visual
perception works with the help of the eye.

The vitreous humor is a clear, gelatin-like fluid within the eye that aids in giving it its rounded shape. It is comprised of several substances, including up to 98% water, sugars, salts, collagen and protein.

<u>Why do forensic scientists use it?</u>
In forensics, the is used to accurately determine a body's time of death. The fluids within the vitreous humor take longer to undergo the decay or putrefaction process. Thus, toxicology may accurately determine this based on the rising potassium levels within the vitreous humor- the levels rise in a steady, predictable pattern for certain time intervals. The potassium levels are usually used in the determination of the time of death or post-mortem interval of a corpse
