I don’t know what plant were presented in your lesson. So, I did sunflowers. The tropism I used was photo tropism
Answer:
Cells
Explanation:
High-powered microscopes are used in order to see microscopical (extremely small) structures of objects that cannot be seen with a naked eye.
When we look at a leaf, we will see the composition of it and the structural patterns that we couldn't see clearly or at all without a microscope.
Leaves consist of cells and spores (stomata) between the cells. Using a microscope will enable us to see them.
Answer:
<u></u>
- <u><em>B) an error occurred, the mass of the reactants should equal the mass of the products. </em></u>
<u><em /></u>
Explanation:
The answer choices are:
- <em>A) no error occurred, some of the products are always lost as heat.</em>
<em />
- <em>B) an error occurred, the mass of the reactants should equal the mass of the products. </em>
<em />
- <em>C) an error occurred, the products should weigh more than the reactants. </em>
<em />
- <em>D) no error occurred, water is not weighed when determining the weight of the products.</em>
<h2>Solution</h2>
The basis to answer this question is the law of conservation of mass.
Any chemical reaction satisfies the law of conservation of mass: mass cannot be either created nor destroyed, so, always, <em>the mass of the reactants equal the mass of the products.</em>
Thus, since he measured the mass of his reactant materials to be 35g and he reported that his products weighed 32g, his data are in clear contradiction of the law of conservation of mass. So, there is an error in his results: <em>the mass of the reactants should equal the mass of the products. </em>
The noble gas notation is the short or abbreviated form of the electron configuration.
It means that you use the symbol of the previous noble gas as part of the electron configuration of an element.
The gas noble previous to antimony is Kr, so you do not use Xe to write the electron configuration of Sb.
The gas noble previous to radium is Rn, so you do not use Xe to wirte the electron configuration of Ra.
The gas noble previous to uranium is Rn, so you do not use Xe to write the electron configuration of U.
The gas noble previous to cesium is Xe, so you use Xe to write the noble notation for Sb. This is it: Cs: [Xe] 6s.
Answer: cesium
The ga
