Answer:
Independent variable: The fertilizer given
Dependent variable: Daily plant growth
Constants: How much water they receive daily, How much sunlight the plants receive, type of plant (tomato plant)
Explanation:
Independent variable of an experiment is the variable that is changed or manipulated by the experimenter in order to bring about a measurable response. In this experiment where Sherri wanted to test what fertilizer worked best on her tomato plants. She used 4 different brands of fertilizer. Hence, the FERTILIZER is the independent variable
On the other hand, the dependent variable is the variable that is measured in the experiment. It is the variable that responds to the independent variable. In this experiment, the DAILY PLANT GROWTH is the dependent variable.
Constants are variables that are kept unchanged or constant throughout the experiment. In this case, the constants or controlled variables are: : How much water they receive daily, How much sunlight the plants receive, type of plant (tomato plant)

5. Describe logistic growth and exponential growth.
Answer:
Population Growth Form: The graphic pattern obtained when a population growth is plotted against time is called population growth form or model. There are two types namely: Exponential J-shaped and Logistic or S-shaped.
J-shaped or Exponential Growth Form: At any point of time, population size does not reach the equilibrium.
Explanation:
When resources are limited, populations exhibit logistic growth. In logistic growth, population expansion decreases as resources become scarce.

Cellular respiration classified as________respiration,occurs in the__________.
Answer:
1.a combustion reaction
2.inside of cells
Explanation:
Although cellular respiration can be classified as a combustion reaction (thanks to its release of energy in the form of heat), because it occurs inside of cells, the energy is released in slow bursts, and only after a series of reactions and processes. As cellular respiration occurs, it produces CO2, carbon dioxide, as a waste product.

How do cyanobacteria photosynthesize?
Answer:
hope it helps...
Explanation:
In general, photosynthesis in cyanobacteria uses water as an electron donor and produces oxygen as a byproduct, though some may also use hydrogen sulfide a process which occurs among other photosynthetic bacteria such as the purple sulfur bacteria. Carbon dioxide is reduced to form carbohydrates via the Calvin cycle.

Why do you think there are rarely 5 or 6 links in a food chain? To help, think about how much food it took for all of your energy needs in your life. Imagine if an animal had to eat 10 humans a year to survive.... is this feasible... or there that much energy available?
Answer:
Most food chains have no more than four or five links. There cannot be too many links in a single food chain because the animals at the end of the chain would not get enough food and energy to stay alive.

which source has the widest range of residence time
Answer:
Underground water source
Explanation:
Underground water source has the widest range of residence time. Underground water are usually present deep under the ground and are formed from the rainfall seeping into the soil and remaining there. Evaporation takes a bit of the water and the remaining are usually present for a very long time.
Underground water residence time usually ranges between few weeks to a thousand years which depicts a very wide range.
Predict what would happen to the H+ ion concentration if you added sulfuric acid to water. Would the pH increase or decrease
When a sulfuric acid is dissolved in water, hydrogen ions are produced, increasing the concentration of hydrogen ions in the solution. Result in decrease in pH of solution.
What is PH solution?Indicating the acidity or basicity of a solution, the pH of a solution measures the molar concentration of hydrogen ions in the solution.
The acronym pH stands for “power of hydrogen,” and the pH value in numbers is simply the negative of the molar concentration of H+ ions divided by 10.
A solution's acidity can be determined by looking at its pH, which is a measurement of hydrogen ion concentration.
Pure water slightly separates into ions with roughly equal amounts of hydrogen and hydroxyl (OH) ions.
Nutrient availability, biological processes, microbial activity, and chemical behavior can all be influenced by pH.
Therefore, if you added sulfuric acid to water, pH decrease.

in the reference to genetics what does dominance and recessive mean
Answer: well see if a trait is dominant you are more likely to have said trait if a trait is recessive you are less likely to have said trait
Explanation:
Answer:
dominance is the one that will be seen in a creature, recessive traits will not be seen, but can still be passed on
Explanation:
if both parents pass on the same recessive gene then their child will show that trait, such as two sets of parents, one dark skinned and one light skinned, their children will be dark skinned, but if their children have a child is has a chance of having light skin because they both carry that recessive trait.

Madison is conducting a biotechnology experiment in her kitchen. Her goal is to make yogurt with a pH of 4.5 in the optimal time of 4 hours. Normally, she uses a mixed culture of L. bulgaricus and S. thermophiles to ferment yogurt. She designs her experiment to include the mixed cultures but also with the L. bulgaricus culture alone to see if one would ferment faster. She graphs her results to display her data.The graph depicts the results of an experiment to make yogurt. Over six hours, milk maintains 6.5 pH. When L. bulgaricus is added to milk, the pH declines from 6.5 to about 4.3 in six hours. When L. bulgaricus and S. thermophilis are added, the pH declines over six hours to approximately 3.5.Study the graph of her results.Certain bacteria that produce lactic acid as a waste product during fermentation, an Choose... process, are important to the food industry. This lactic acid is what gives yogurt its Choose... taste. From the graph, based on the pH after 4 hours, the Choose... would taste the most acidic.
Answer:
Firstly, Milk alone did not ferment or change in pH at all, showing that it is a control variable on this experiment. The L. bulgaricus culture alone did not meet Madison's goal to make yogurt with a pH of 4.5 within 4 hours; however, the mixed culture S. thermophilis and L. bulgaricus met Madison's goal of reaching a 4.5 pH. In conclusion, the mixed culture is the fastest fermenting culture that madison has, and it meets her goal of reaching a pH of 4.5 in the optimal time of 4 hours.
