sex hormones

Answer the following question given this paragraph: Carbon dioxide emissions into the atmosphere from fossil fuel burning have been rising for the past several decades. Q: Emissions of what gas into the atmosphere from fossil fuel burning have been rising for the past several decades? A:
OPTIONS:
- sulphur
- oxygen
- neon
- carbon dioxide

Answer: carbon dioxide

Question: Answer the following question given this paragraph: Photosynthesis changes light energy to chemical energy. The chemical energy is stored in the bonds of glucose molecules. Glucose, in turn, is used for energy by the cells of almost all living things. Photosynthetic organisms such as plants make their own glucose. Other organisms get glucose by consuming plants (or organisms that consume plants). Q: What does photosynthesis change light energy into? A:
OPTIONS:
- electrical energy
- carbon energy
- radiation energy
- chemical energy
Answer: chemical energy

input with options: Answer the following question given this paragraph: Q: Who controls prey population? A:
OPTIONS:
- ecosystems
- bees
- parasites
- predators
output: predators

Q: Answer the following question given this paragraph: Members of the genus Trypanosoma are flagellate protozoa that cause sleeping sickness , which is common in Africa. They also cause Chagas disease , which is common in South America. The parasites are spread by insect vectors. The vector for Chagas disease is shown in Figure below . Trypanosoma parasites enter a person's blood when the vector bites. Then they spread to other tissues and organs. The diseases may be fatal without medical treatment. Q: Members of the genus trypanosoma are flagellate protozoa that cause what? A:

OPTIONS:
- cancer
- hypertension
- mutations
- sleeping sickness

A: sleeping sickness

Answer the following question given this paragraph: What is a cell? Gradient Physical difference between two regions of space, in such a way that the molecules tend to move in response to the gradients. Diffusion Movement of the molecules in a fluid, from the regions of high concentration to those of low concentration. Passive transport Movement of substances in a membrane that doesn't need to use energy. Simple diffusion Diffusion of water, gases or molecules across the membrane. Facilitated diffusion Diffusion of molecules across the membranes with the participation of proteins. Osmosis Diffusion of the water across a membrane with differential permeability. Transport that needs energy Movement of substances across a membrane generally in opposition to a gradient of concentration with the requirement of energy. Active transport Movement of small molecules using energy (ATP). Endocytosis Movement of big particles towards the interior of the cell using energy. The cells enclose particles or liquids. Pinocytosis (Literally cell drinking) Form in which the cell introduces liquids. Phagocytosis Way of eating of the cells. It feeds in this case of big particles or entire microorganisms. Pseudopods False feet (the amoeba). Exocitosis Movement of materials out of the cell with the use of energy. It throws waste material. Isotonic The cytoplasm fluid of the interior of the cells is the same that the outer. Hypertonic solution. Q: Pseudopods are false what? A:
OPTIONS:
- eyes
- teeth
- fingers
- feet
feet
