a. State any two parts of the brain. b. Mention any two excretory products. c. Explain any one adaptation of a leaf to photosynthesis. d. Describe how fraternal twins are produced. 2. Figure 1 is a diagram of the human digestive system. Use it to answer the questions that follow.

a) Step 1: Identify two major parts of the brain. • The brain consists of several parts, including the cerebrum, cerebellum, and brainstem. The two parts are: 1. Cerebrum 2. Cerebellum b) Step 1: Identify two substances excreted from the body. • Excretory products are waste substances removed from the body. The two excretory products are: 1. Urea 2. Carbon dioxide c) Step 1: Explain one adaptation of a leaf for photosynthesis. • Leaves are adapted for photosynthesis in several ways, such as having a large surface area to absorb maximum sunlight. One adaptation is: Leaves have a large surface area to absorb as much sunlight as possible for photosynthesis. d) Step 1: Describe the process of fraternal twin formation. • Fraternal twins, also known as dizygotic twins, occur when two separate eggs are released from the ovary and are fertilized by two different sperm. The process is: Fraternal twins are produced when two separate eggs are released from the mother's ovaries and are each fertilized by a different sperm. This results in two distinct zygotes, which develop into two separate embryos. Send me the next one 📸
