Answer:
Global climate models usually work by managing the planet as a set of connected boxes because this facilitates the management of the calculations applied in a climate system that is dynamic, variable and complex, which is due to the fact that there is not an equal pattern of climate in each area of the planet.
Explanation:
Climate models have been designed to show the dynamics of the planet's climate and what can be expected from the changes that occur in the future.
The scientific basis of a climate model is physical phenomena and chemical reactions to which a series of differential calculations are applied to determine the behaviour of:
Global climate models usually divide the planet into sections -such as boxes- making the calculations in each sector, as well as the interaction of each section with the adjacent sections, which greatly facilitates making the differential calculations, showing the climate at a given time and making predictions of future climate behavior.
It is important to mention that a climate model also explains the changes that occur in the climate due to human activity, which is different in each region of the world.

Answer:
Sunlight
Explanation:
Abiotic means not alive, and the insects and fish options are alive, so we can eliminate those. Sunlight and rocks are left. Of these, the rock would not affect the water lilies, not as much as sunlight at least. Without sunlight, the water lilies would not be able to grow and thrive as all plants/flowers have sunlight as one of their basic needs, so sunlight must be the answer.
b. cells do not have much thermal energy; they are relatively cool.
c. temperature is usually uniform throughout a cell.
d. heat can never be used to do work.
Answer:
Temperature is usually uniform throughout a cell (Ans. C)
Explanation:
Heat or thermal energy is a kinetic energy. That is connected with the random movements present in the atoms. Temperature is usually uniform throughout the cell so the most cell can not harness heat to perform work.
Heat is a type of energy which is transfer from one body to another body due to the temperature difference.
It can only perform work if it is transferred from one source which is warmer to a body which is cooler. The temperature in living organisms is usually kept very constant due to the process of homeostasis.
Most cells cannot harness heat to do work because temperatures within the cell are typically uniform, so there's no heat gradient for work to be conducted. Heat tends to be lost instead.
Most cells are not able to harness heat to perform work because heat energy is often dissipated as waste during biochemical reactions. The correct option is c. The temperature is usually uniform throughout a cell. This means that there isn't a high temperature gradient in the cell, which would be needed in order for heat to be used for work. For heat to be harnessed and used for work, there must be a temperature difference because work is done when heat flows from a hotter area to a cooler one. Without a temperature gradient, heat energy cannot be used to perform work within a cell and is instead lost to the surrounding environment.

Answer:
Explanation:
Each of the organelles in the cytoplasm of a cell composed of water, proteins and RNA, and whose function is to participate in the synthesis or manufacture of proteins.
Answer: Arginine is an amino acid that is incorporated into proteins. So if cells can not make or obtain arginine, the cell can not make proteins needed for survival.
Explanation:
Arginine is an amino acid used to build proteins, and it is classified as a semiessential or conditionally essential amino acid.
Proteins are large molecules consisting of long chains of amino acids. They perform many functions such as catalysing metabolic reactions, providing structure to cells and organisms, and transporting molecules, among many others.
Most notably, arginine is part of proteins that play an important role in many different processes such as cell division, immune function, wound healing and the release of hormones. Without this amino acid, the cell cannot manufacture the proteins necessary for proper functioning. So the cell dies because it cannot function properly.
The function of the Calvin cycle is to take CO2 from the air and bond it together to form the molecules that will make the sugar glucose. This process is called carbon fixation . The actual result of the Calvin cycle is not glucose, a 6-carbon sugar, but another molecule called G3P. G3P is an abbreviation for glyceraldehyde-3-phosphate. This molecule is later converted by other chemical reactions into glucose.
