<span>Opaca and Marginal zone stays outer and does not move during chick gastrulation,
The zone opaca is a thick fringe ring comprising of more than one cell, it is joined to the germ wall. The Marginal zone lies at the fringe between the range opaca and the region pellucida</span>
Answer:
The correct answer is - Photosynthesis takes carbon from the atmosphere and brings it to the geosphere and into plants.
Explanation:
Photosynthesis is the process that involves converting light energy to chemical energy stored in the form of sugars with the help of carbon dioxide and water as reactants.
The carbon is pulled from the atmosphere in the form of carbon dioxide for the process to the geosphere and then used by the plants (biosphere). In plants, it is trapped by the chlorophyll present in chloroplasts and water is entered in the light-dependent reaction and carbon dioxide is used in the light-independent reaction.
The specific water heat has an elevated capacity that requires more amount of energy to heat.
Explanation:
By the’ heat capacity’ we mean the absorbing capability of heat in a material and ‘specific heat’ determines the heat amount required for increasing the water temperature of 1 gram by 10 Celsius.
Water has a high heat capacity that is caused by its hydrogen bonding. When heat is applied in water and is absorbed by it, it breaks the bond of hydrogen influencing molecules of water to travel freely. This specific heat in water makes it take longer time to heat and to cool.
Answer:
To understand how insulation works it helps to understand heat flow, which involves three basic mechanisms -- conduction, convection, and radiation. Conduction is the way heat moves through materials, such as when a spoon placed in a hot cup of coffee conducts heat through its handle to your hand. Convection is the way heat circulates through liquids and gases, and is why lighter, warmer air rises, and cooler, denser air sinks in your home. Radiant heat travels in a straight line and heats anything solid in its path that absorbs its energy.
Most common insulation materials work by slowing conductive heat flow and convective heat flow. Radiant barriers and reflective insulation systems work by reducing radiant heat gain. To be effective, the reflective surface must be in contact with an air space.
