Answer:
Enzymes are proteins that catalyse (speed up) vital chemical reactions inside the body. Enzymes will only function properly under a small range of certain conditions, such as preferred pH and temperature. If any conditions are outside their specific range then the enzymes cannot function. This could cause the organism to die. Homeostasis relies on automatic control systems that include nervous responses (nervous system) or chemical responses (endocrine system). Receptors and effectors are also needed

Answer: Name the predominant fatty acid in each of the vegetable oil are given below:
1) The predominant fatty acid in groundnut oil is oleic acid. Its percentage in the groundnut oil is 46.8% on weight basis.
2)The predominant fatty acid in coconut oil is lauric acid acid. Its percentage in the coconut oil is 47 - 49% on weight basis.
3)The predominant fatty acid in palm oil is palmitic acid. Its percentage in the palm oil is 44% on weight basis.
Answer:
A. <u>Biomes are not affected by climate</u>
Explanation:
-
The climate of a biome determines its importance as the biomes are formed as a cause and consequence of the climatic factors and hence the plant growth is affected by this and depends on the climatic types hence the Koppen classification is based on the different climatic zones the relationship among the plantains.
- An example of the Mediterranean climate i.e Cs chappal biome. Has and extremely dry summers and plants are adapted to the extreme season of the variation in the temperatures and the rainfall patterns.
Answer:
D
Explanation:
Water has a fairly high specific heat, which means that enough heat must be added to it to break the hydrogen bonds between the molecules, allowing them to move freely from each other and escape the water's surface.
<u>Answer:</u>
<em>
heat is released by the combustion of
of methane</em>
<u>Explanation:</u>
The value of enthalpy determines whether the reaction is exothermic or endothermic. If the enthalpy change is positive, then the reaction is endothermic (heat or energy released) and if the enthalpy change is negative then the reaction is exothermic (heat or energy absorbed).
