Q: What is the hypothesis that states that the biosphere is its own living organism? Read this paragraph and choose the correct option from the provided answers: The Gaia hypothesis states that the biosphere is its own living organism. The hypothesis suggests that the Earth is self-regulating and tends to achieve a stable state, known as homeostasis . For example the composition of our atmosphere stays fairly consistent, providing the ideal conditions for life. When carbon dioxide levels increase in the atmosphere, plants grow more quickly. As their growth continues, they remove more carbon dioxide from the atmosphere. In this way, the amount of carbon dioxide stays fairly constant without human intervention. Choices: - Big Bang theory - Geiger theory - Pascal's hypothesis - gaia hypothesis A:
(A).
gaia hypothesis

It is a gamete with a haploid number of chromosomes, formed through meiosis. The egg shell membrane encloses the nucleus containing the genetic material and the cytoplasm. Choices: - cerebellum - enamel - exoskeleton - cytoplasm A:

Q: What organ interprets what our sensory organs sense? Read this paragraph and choose the correct option from the provided answers: Sensory neurons in each sense organ receive stimuli, or messages from the environment that cause a response in the body. For example, sensory neurons in the eyes send messages to the brain about light. Sensory neurons in the skin send messages to the brain about touch. Our sense organs recognize sensations, but they don't tell us what we are sensing. For example, when you breathe in chemicals given off by baking cookies, your nose does not tell you that you are smelling cookies. That's your brain's job. The sense organs send messages about sights, smells, and other stimuli to the brain ( Figure below ). The brain then reads the messages and tells you what they mean. A certain area of the brain receives and interprets information from each sense organ. For example, information from the nose is received and interpreted by the temporal lobe of the cerebrum. Choices: - nerves - lungs - thyroid - brain A:
(A).
