18°C converted to Fahrenheit is 64.4° F
The lichens show mutualism and they are found in every biome of the Earth. The lichens have algae and fungus associated with them and they live in a mutualistic relationship with each other. Lichens can grow on soil where no other species can grow like rocks, barren soils and they enrich the soil on dying where other plants and trees can grow.
Lichens being pioneer species change the environment by building up the soil and liberating nutrients. Also the lichens contribute to the chemical weathering of the soil releasing phosphate along with erosion and weather conditions.
When the simple plants die, the wildflowers and other plants start growing replacing lichens or mosses.
From the above explanation it can be concluded that lichens alter the abiotic environment and favor other species of plants to grow by breaking down rocks from soil and providing nutrients.
Answer:
ventilation
Explanation:
Breathing, also known as ventilation, is the process of moving air or water in order to facilitate the gas exchange between the external and internal (body) environment, mostly to eliminate carbon dioxide (CO2) and bring in oxygen (O2). For example, fish are aquatic animals that need to run water over their gills to get the O2 that they need to survive (gills are organs that create a large surface area for ventilation). Moreover, insects ventilate their tracheal system to get O2. Finally, terrestrial vertebrates (i.e., amphibians, reptiles, birds, and mammals) use organs called lungs to exchange O2 and CO2 between their cells and the external environment.
An enzyme's shape is determined by the sequence of amino acids in its structure, and the bonds which form between the atoms of those molecules. ... Different types of enzymes have different shapes and functions because the order and type of amino acids in their structure is different.
Denature means to destroy the characteristic properties of (a protein or other biological macromolecule) by heat, acidity, or other effect which disrupts its molecular conformation.
Answer: Option A.
Explanation:
Crystal meth is a type of methamphetamine drug that is in form of glass or shiny bluish rocks. It is a highly addictive stimulants that affect the Central nervous system. It is used to treat sleep disorder and attention deficit hyperactivity disorder. The drug increases the dopamine level in the brain.
