- Cobalt Chloride paper is used as an indicator for testing water leaks or high humidity. Moisture turns the paper light pink/white.
Goat Bladder Paper is a semi-permeable membrane that restricts the passage of colloidal solutions.
Cobalt Chloride paper Goat Bladder Paper It is used for the process of transpiration to check the presence of water. It is for the process of osmosis as a semi-permeable membrane.
2. ACTH - Adrenocorticotropic hormone is secreted by the pituitary gland and stimulates the adrenal cortex.
IAA - Indole-3-acetic acid is a type of auxin. It is a naturally occurring plant hormone.
ACTH - Adrenocorticotropic hormone IAA - Indole-3-acetic acid ACTH controls the production of another hormone called cortisol produced by adrenal glands, which are located above the kidneys. Cortisol plays an important role in responding to stress. IAA is the main auxin in plants, regulating growth and developmental processes such as cell division and elongation, tissue differentiation, apical dominance, and responses to light, gravity, and pathogens. Roots are most sensitive to fluctuations in IAA level.
3. Greenhouse gases are those which take part in the greenhouse effect and have a negative effect on the environment. Example - Increase in temperature. Some examples of greenhouse gases are Carbon dioxide, Methane and Nitrous Oxide.
Ozone Depleting Substances are man-made gases that are known to destroy ozone once they reach the ozone layer. Some examples are chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), and hydrobromofluorocarbons (HBFCs).
Greenhouse gases Ozone Depleting Substances They trap heat that would otherwise escape from the atmosphere, hence result in raising the temperature of Earth. These are chemicals that damage the ozone layer in the upper atmosphere. Some ODS also have a global warming potential so they contribute to climate change.
4. Transpiration is the process of water passing out from the surface of a plant or leaf.
Guttation is the secretion of droplets of water from the pores of plants.
Transpiration Guttation Removal of pure water in the form of water vapor, through opening and closing of stomata from the surface of leaves during daytime. It produces a cooling effect and can also lead to the wilting of leaves. Secretion of water droplets that might contain organic and inorganic substances, from the margin of leaves in the nighttime or early morning, depending upon the availability of water in the plant and humidity.
5. Synapsis is a term used in cell biology. for the fusion of two homologous chromosomes.
Synapse is a term used in neuroscience for the junction between two neurons.
Synapsis Synapse It is the fusion of two homologous chromosomes during meiosis, which facilitates the exchange of genetic material and also results in the production of recombinant chromosomes. It is the junction where two neurons propagate nerve impulses, hence facilitating the nerve impulse transmission between the gaps between two neurons.
