Answer:
mg of powder 1 and mg of powder 2
Explanation:
Let "X" denotes weight of powder 1 added to the new mixture and "Y" denotes weight of powder 2 added to the new mixture
Total weight of vitamin B1 in the mixture is equal to mg
Total weight of vitamin B2 in the mixture is equal to mg
Equation 1
Equation 2
Let us simplify the above two equations, we will get
Substituting value of X in equation 2 we get
The answer to this question would be letter C because a dependent variable depends on the project. For instance, If there is a scientist trying to see which plant will grow the fastest just using water. The plant depends on the water. hope this helps!
Molecular clocks B. TAKE ADVANTAGE OF THE FACT THAT ALL MUTATIONS HAPPEN AT A STEADY RATE.
The molecular clock is a technique used involving the mutation rate of biomolecules to deduce when in prehistoric times have two or more lifeforms diverged.
Answer:
Oxygen is formed from carbon dioxide in <u><em>photosynthesis</em></u>, while carbon dioxide is formed from oxygen in<u> </u><u><em>respiration. </em></u>
Explanation:
Photosynthesis can be described as the process by which plants make glucose and oxygen from carbon dioxide and water in the presence of sunlight. By this method, plants are bale to make their own food. Cellular respiration can be described as a process by which plants convert oxygen and glucose into water and carbon dioxide along with the release of ATP. The process of photosynthesis and cellular respiration are opposite of one another and are equally essential.
