Plants and animals use glucose as a soluble, easily distributed form of chemical energy which can be 'burnt' in the cytoplasm and mitochondria to release carbon dioxide, water and energy. Pure monosaccharides, such as glucose, attract water.
An animal's body breaks down carbohydrates and converts them into simple sugar such as glucose. Glucose in the form of energy is carried through the blood and delivered to every cell of the body.
What is the function of sugar in animals?Carbohydrates are an important compound of all life on this planet. Both plants and animals utilize carbohydrates as a source of energy to keep their body functioning at the most basic level.
Carbohydrates fulfill needs by helping in the synthesizing of other chemicals and giving structure to cells within the body. Carbohydrates are carrying out normal functions such as growth, movement, and metabolism.
Carbohydrates store energy in the form of starch and provide either simple or complex sugars. Polysaccharides, give a steady supply of energy while sugars, monosaccharides, and disaccharides, supply quick energy on dissolving.
Carbohydrates have the side effect of helping with the processing of other body's chemicals. As carbohydrates break down, they release energy.

Consider the following system at equilibrium. CaCO3(s) Double headed arrow. Ca2 (aq) CO32â€""(aq) The addition of which compound will cause a shift in equilibrium because of a common ion effect? CCl4 CO2 CuSO4 Na2CO3.
The compound that has been capable to shift the equilibrium with common ion effect has been [tex]\rm \bold{Na_2CO_3}[/tex]. Thus, option D is correct.
The complete equation for the decomposition of calcium carbonate has been:
[tex]\rm CaCO_3\rightleftharpoons Ca^2^+\;+\;CO_3^2^-[/tex]
The equilibrium has been the state in the reaction, when the number of products and has been equivalent to the number of reactants. The increase or decrease in the concentration of any of the reactant or product results in the shift in the equilibrium.
For the given reaction, the addition of Calcium or carbonate ions to the solution results in the increase in the product concentration with the common ion effect, and thereby shifts the equilibrium condition.
The ions liberated by the following compounds has been:
[tex]\rm CCl_4\;=\text{not dissolved}\\CO_2\;+\;H_2O\leftrightharpoons CO_3^-\;+\;H^+\\CuSO_4\leftrightharpoons Cu^2^+\;+\;SO_4^2^-\\Na_2CO_3\leftrightharpoons 2\;Na^+\;+\;CO_3^-[/tex]
The compound, that has been capable of liberating the carbonate ions in the medium has been [tex]\rm \bold{Na_2CO_3}[/tex]. Thus, it results in the shift of the equilibrium due to common ion effect. Hence, option D is correct.

an electric field. In which two ways did this experiment change scientists' understanding of the atom?
O It showed that atoms combine in different proportions.
O It showed that atoms can be divided into smaller parts.
M It showed that all atoms of the same element are similar.
D
It showed that individual atoms could be destroyed
showed that all atoms contain electrons.
The two ways the cathode ray tube experiment changed scientists'
understanding of the atom was it showing that atoms can be divided into
smaller parts and all atoms contain electrons.
J.J Thompson was the scientist which performed the cathode ray tube
experiment and was able to ascertain it was negatively charged as a result
of it being deflected to the positive electrode.
His observation showed that the atoms contain sub-atomic particles called
electrons which are negatively charged.

The percent of attacks on the dark-colored mouse models is how many times greater than the percent of attacks on light-colored models
The number of times the percentage of attacks on the dark-colored mouse is greater than the percentage of attacks on light-colored mouse is four (4) times.
Let the percent of attacks on the dark-colored mouse be D.Let the percent of attacks on light-colored mouse be L.Given the following data:
Light-colored mouse models = 20 percentDark-colored mouse models = 80 percentTo determine the number of times the percentage of attacks on the dark-colored mouse is greater than the percentage of attacks on light-colored mouse.
Therefore, we would simply divide the percentage for the dark-colored mouse by the percentage for the light-colored mouse as follows:
[tex]Number \;of\;times = \frac{D}{L}[/tex]
Substituting the given parameters into the formula, we have;
[tex]Number \;of\;times = \frac{80}{20}[/tex]
Number of times = 4 times.
