Answer:
enzymes are biological catalysts which speed up the rate of biochemical reactions
Increasing the concentration of enzymes would speed up the rate of photosynthesis and respiration due to the fact that the enzyme substrate complex can occur on a much larger scale i.e. more enzymes would be able to bind with more substrates producing more Oxygen in the case of photosynthesis and more ATP in respiration
Decreasing the concentration of enzymes would have the opposite effects
The differences in enzyme concentrations affect rates of photosynthesis and respiration are process accelerators.
What enzymes are involved in photosynthesis?Enzymes such as Rubisco, sedoheptulose-1,7-bisphosphatase, aldolase and transketolase dominate the control of photosynthesis. Reductive fixation of CO2 requires ATP and NADPH and their concentrations in the stroma increase when chloroplasts are illuminated.
The chemical reactions involved in photosynthesis are controlled by enzymes . The temperature increases the number of collisions increases, therefore the rate of photosynthesis increases. However, at high temperatures, enzymes are denatured and this will decrease the rate of photosynthesis.

Explanation:
describe in detail, the pathway of an oxygen molecule as it moves from the air outside your body, into your blood and to cell in a muscle in your arm
Answer:
The oxygen molecule enters the human body from the mouth or nose and reaches the phraynx and then the larynx, trachea and the bronchus. It then enters the lungs which then the red blood cells takes the oxygen from the blood and carries it to the muscle in the arm.
The pathway of an oxygen molecule from the air outside your body to a muscle cell in your arm involves several sequential steps, including inhalation, gas exchange in the lungs, transportation through the bloodstream, and diffusion into muscle cells.
During inhalation, you breathe in air through your nose or mouth. The air travels through your respiratory system, passing through the trachea (windpipe) and into the bronchi, which branch into smaller tubes called bronchioles. Eventually, the inhaled air reaches the alveoli, tiny air sacs located at the end of the bronchioles in the lungs.
In the alveoli, oxygen molecules diffuse across the thin walls of the air sacs and into the surrounding capillaries. Oxygen diffuses from an area of higher partial pressure (in the alveoli) to an area of lower partial pressure (in the capillaries). Hemoglobin, a protein within red blood cells, binds to the oxygen molecules in the capillaries, forming oxyhemoglobin.

19. Engineer It In some rivers and lakes, dams
are constructed to harvest energy by converting the
kinetic energy of moving water into electrical energy.
Water from behind the dam flows through a turbine
that transforms kinetic energy into mechanical
energy. The turbine turns a generator that converts
mechanical energy into electrical energy.
The water from behind the dam could flow to the
turbine either through an opening near the middle or
top of the dam or by flowing over the top of the dam.
Which type of water flow would be the best design for
sending a consistent flow of water past the turbines?
Explain your reasoning.
Answer:
A hydroelectric dam converts the potential energy stored in a water reservoir behind a dam to mechanical energy—mechanical energy is also known as kinetic energy. As the water flows down through the dam its kinetic energy is used to turn a turbine.

Explanation:
in q 1, part a, we need to tell what we observed in the growth of plants. we observed that the plant h was groing faster and healthier that plant g due to the fact that it was provided with a nutritive solution.
in its part b, we write the conclusion, i.e the plant which was provided with a nutritive solution grew more as all minerals required by the plants were replenished properly.
In q2, part a, we just compare their physical properties such as the plant g was not as healthy as plant h and plant h grew faster and taller than plant g.
in q2, part b, we just write what the solution is supplying the plant with, you can also check each one of their speciality on the web and write it also.

why would one gene work as a barcode for one species and not for another
One gene work as a barcode for one species and not for another because for different species different barcodes are used.
Every specie is different than another organism genetically so it also needs different barcodes for every other specie. If all the species are made up of the same gene then we can say that one barcode is used for all of them but its not the case.
Every organism has different and its own gene so one gene barcode is not acceptable for all species but for the original one so we can conclude that one barcode is used for one species and not for another.
