The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Air moves in and out of the lungs through the trachea, bronchi, and bronchioles. Blood moves in and out of the lungs through the pulmonary arteries and veins that connect to the heart.
Digestive System gets nutrients (good) from food and hands it over to the blood and Circulatory System then carries those nutrients where they need to go.
The excretory system removes waste from the body. remove waste from the blood. The digestive system breaks down the food you eat into nutrients that provide energy and building materials for cells. The digestive and excretory sytems work together to process the food that you eat.
I believe the correct answer from the choices listed above is the last option It is Joseph Proust's law about the ratios of masses of elements in a compound did John Dalton’s work on the atomic structure help to explain. <span>Dalton's law of multiple proportions is part of the basis for modern atomic theory, along with </span>Joseph Proust's<span> law of definite composition. Hope this answers the question.</span>
Answer:
<em>The above statement is false.</em>
Explanation:
<em>When a single nucleotide is changed at a particular position of the nucleotide sequence, then this change will result in the formation of a faulty protein. </em>
<em>This is because that particular position of the genetic sequence is associated with the formation of a particular protein. All the other proteins formed will be normal. </em>
<em>Hence, we cannot attribute all existing changes between the cichlid and coelacanth/frog on this single nucleotide change.</em>
However, if instead of replacement of a T with a C, an addition or deletion had been made, then the entire genetic code would have been altered. This would have resulted in more number of faulty proteins being formed.
The phosphorous cycle is not considered a true cycle because unlike the others such as the water, carbon, nitrogen and sulphur cycles, it does not include a gas phase, although small amounts of phosphoric acid may make their way into the atmosphere contributing , in some cases, to acid rain.
Very little phosphorous circulates in the atmosphere because at Earth's normal temperatures and pressures, phosphorous and its various compounds are not gases. The largest reservoir of phosphorous is in sedimentary rock.
