Answer:
The conclusion is that different matters have different biomass percentages.
Explanation:
Different matters have different biomass percentages because they are formed from different elements. each biomass is formed from the elements such as carbon, oxygen, hydrogen and nitrogen. for example, the human body is composed of 30 percent of biomass while 70 percent is water. the percentages of different elements are carbon (12%), nitrogen (0.6%), hydrogen (62.9%), oxygen (24%), calcium (0.24%) and phosphorus (0.14%). At each level, only 10 percent of biomass is transferred to another level and remaining 90 percent releases in the form of heat.
Answer:
The correct answer would be - 1. group 2.period 3. less 4. more
Explanation:
elements that have a place with same group contains same number of valence electrons. Thus, they will in general show comparable chemiccal properties.
At the point when we move over a period at that point number of electrons get added to a similar shell. Therefore, there will be no expansion in size of elements.
Additionally, metals are the elements that have a place with group 1, 2 and d-block group are otherwise called metals. Metallic character of elements diminishes when we move left to directly in a periodic table.
As most responsive metals are put on the left half of occasional table.
Since, size of elements increases on descending the groups. Along these lines, a elements can lose its valence electrons due to the less forrce of ttaraction between valence electrons and its neucleus.
Answer:
b. Some carbon dioxide will move from chamber A to chamber B.
Explanation:
The two chambers are separated from each other by a separator that exhibits the properties of the cell membrane. It means that the separator film is semi-permeable in nature. The concentration of CO2 in the chamber A is 80%. This is relatively higher than its concentration in chamber B (20%). The concentration gradient will drive the passive diffusion of some of the CO2 from chamber A to chamber B so that the concentration becomes equal in both the chambers.
