Answer:
Carbon can bond with many elements
Explanation:
Carbon can bond with many elements, including itself, to form macromolecules. Moreover, it can form four bonds, and that makes possible many different arrangements of the atoms in the molecules.
A is <em>wron</em>g. Carbon is among the seven smallest elements in the Periodic Table.
C is <em>wrong</em>. Carbon is found in living things because it can form macromolecules, not the other way around.
D is <em>wrong</em>. Carbon can bond with many other elements beside itself.
The correct answer is:
CO2 diffuses passively out of the cell.
O2 in respiration is converted to water. O2 diffuses in to the cell.
Explanation:
Cellular respiration is the chemical reaction in which glucose and oxygen are converted into water, carbon dioxide, and energy (ATP). In this reaction, glucose and oxygen are reactants, while water, carbon dioxide, and energy (ATP) are products. Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to change biochemical energy from nutrients into adenosine triphosphate and then discharge waste products.
Answer: Lets choose a food processing company for scientific study.
Explanation:
Scientific study is the study which involves taking observations on the samples being studied experimentally. Drawing evidences from observations to prove a scientific fact.
In a food based company, several scientific tests are required to be done to check the shelf-life, quality, quantity of the ingredients, and to check whether they are fit for consumption or not all of these parameters have to checked through experimental procedures.
Knowing that she is already 75 years old, even though we don't know her health conditions, we can conclude that the vitamins might help her to avoid any deficiency related to minerals and vitamins, and it might also help her if she has an alimentary restriction meaning that she can't it a food that contains a needed vitamin or mineral.
Hope it helps,
Happy homework/ exam/ study!
