Answer:
Respiration is a process in which energy is released due to the breakdown of glucose molecules with the addition of oxygen forming carbondioxode, water and energy in the form of Adenine tri phosphate (ATP). In respiration process, carbondioxide is released in the atmosphere and oxygen is used for breakdown of food. This carbondioxide is used by the plants in the process of photosynthesis and oxygen is released in the atmosphere which is again used by animals for respiration.
1- Combustion reactions are exothermic reactions since these reactions result in the emission of heat (heat is a product and not a reactant)
2- A substance with higher specific heat that water would be liquid ammonia. This means that, for the same amount of energy given to both water and liquid ammonia, water will heat faster and gain more thermal energy (in degree celcius) that liquid ammonia.
3- Conduction : occurs when heat is directly transmitted from a material to another due to the difference in temperature between both. Examples are:
a- when using an iron the heat is transferred from the iron to the piece of clothe being ironed
b- if you hold a hot cup heat will transfer to your hand
c- when you hold chocolate with your bare hand it will melt due to the transfer of heat from your hand to the chocolate
d- when you heat food on the stove the heat will transfer from the flame to the pan
e- when you hold ice it melts due to the transfer of heat from your hand to the ice piece
f- when you place hot liquid in a cup the heat will transfer from the liquid to the cup and the cup will become hot
g- if you place a spoon in a plate containing hot food the heat will be transferred from the food to the spoon making it hot
h- when you walk on the sand beach during summer the heat will be transferred from the sand to your feet and your feet will be hot
i- if you hold someone's hand when he/sh is cold the heat will be transferred from your hand to his/hers
j- Light bulbs emit heat, if you touch them this heat will be transferred to your body
4- Convection : is the transfer of heat through liquids or gases. Examples:
a- when water at the bottom of a pot is heated, it transfers this heat to the water above by convection
b- the process of ice melting when left in the air where heat is transferred from the air to the ice
c- the same goes for chocolate melting
d- cooling a frozen substance using running water where heat is transferred from the water to the frozen substance
e- when you stream a hot cup of tea/coffee, you transfer heat from the tea/coffee to the air
f- when a radiator moves the hot air upwards and the cold air downwards
g- when a balloon rises up wen being filled with hot air
h- when the ocean circulates and heat is transferred from warm water to cool water
i- when heat is transferred from a bulb to the surrounding air
j- when you cool the radiator of your car using water where water is transferred from the radiator to the water.
5- Radiation: the emission of energy in the form of waves. Examples:
a- the sunlight (ultraviolet radiations of sunlight)
b- x-rays
c- the flame/light of a candle
d- the gamma radiations from the explosion of a star
e- microwaves of a microwave oven
f- the radiations of the mobile phone which are electromagnetic radiations
g- the beam of a laser
h- placing your hand over warm fire
i- emission of alpha particles from decaying uranium
j- the radio waves
Answer:
The high specific heat of water caused by hydrogen bonding
Explanation:
Specific heat capacity of a substance is the quantity of heat required to raise the temperature of a unit mass of that substance by one degree Celsius (1° C).
Due to the hydrogen bonding present in water, water has a high specific heat capacity of 4184 Joules per kilogram. This means that, water has to absorb 4,184 Joules of heat for the temperature of one kilogram of water to increase 1°C. When compared to other substances such as metals, this is very high. For example, the specific heat capacity of copper is 385 Joules per kilogram which means that it only takes 385 Joules of heat to raise 1 kilogram of copper 1°C.
Therefore water, can absorb a large quantity of heat with very little changes in its temperature. This property of water helps the oceans and seas to serve as heat reservoirs by absorbing a large quantity of heat in hotter seasons and releasing these heat in colder seasons.
You have transcription in which DNA is transcribed into mRNA , then there is Translation in which mRNA is translated into proteins, in other words mRNA translated into amino acids that are going to be bonded together to become a protein
The answer is it has the similar ecological communities and very different species. An ecological community is a certainly happening group of native plants, animals and other organisms that are interacting in a unique habitat. Its structure, composition, and distribution are strongminded by environmental factors such as soil type, position in the landscape, altitude, and climate and water availability.
