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.
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.
Please help!!! Below is a scenario about an experiment; there are three questions referring back to this scenario, so read it carefully. Sherri wanted to test what fertilizer worked best on her tomato plants. She bought 4 different brands of fertilizer, and five tomato plants. She labeled each plant A-E. She did not give plant E any fertilizer. Each plant was kept in the same location, with the same amount of sunlight, and given the same amount of water each day. Each day at noon she measured her plants. 1. What is the independent variable in this scenario? - The type of plant - The growth of the plants - The amount of water given - The fertilizer given 2. What is the dependent variable? - The type of fertilizer - The amount of water given to each plan - The type of plant - Daily plant growth 3. Select all of the controlled variables present. - The type of plant - The type of fertilizer - How much sunlight the plants receive - How much water they receive daily
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)
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.

What are chromosomes?A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are the histones.
Moreover, chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.
Therefore, chromosomes are threadlike structures made of protein and a single molecule of DNA that serve to carry the genomic information from cell to cell. In plants and animals (including humans), chromosomes reside in the nucleus of cell.

7. Mateo and Jackie were on a playground rolling some different sized balls to get them to crash. They
used a tennis ball (the same mass) in both crashes. They tried two Soccer balls-a pink one (more
mass) for Crash l the and a blue one (less mass) for Crash 2.
Answer:
b
Explanation:
beacuse it b and ghcgdd
The answer is A
This is because since the pink soccer ball has a larger mass than the smaller blue soccer ball, it would take a stronger force to move it than it would for blue soccer ball.
What is an example of the effect of environmental factors on cell differentiation?
A. The plant hormones known as auxins stimulate cell elongation in roots and stems.
B. The sex of turtles is determined by temperatures in the nest during incubation
C. The kidneys release more urine in response to an increase in blood pressure.
D. The menstrual cycle is controlled by the hormones estrogen and progesterone.
Answer:
Environmental factors can also influence gene expression and cell differentiation. For example, available nutrients, salinity, and temperature are all factors that can influence gene expression in organisms. In Himalayan rabbits, genes that code for fur color are turned on and off depending on temperature.
Explanation:
I dont have an exact answer but this can help
An example of the effect of environmental factors on cell differentiation is : ( B ) The x of turtles is determined by temperatures in the nest during incubation

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.

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.
