Which of the following is the correct definition of biomass
Answer:
The total amount of organic matter from plants and animals in a habitat.
Explanation:
Biomass can be defined in ecological terms and in industrial (environmental science) terms. Ecologically, it is defined by the total mass of organisms (not organic matter) given a specific area or ecosystem. This definition is not in the choices therefore the industrial term for environmental science should be appropriate. In environmental science, biomass is the organic matter from living organisms whether wastes or dead animals or plants that can be used as fuel in powering power plants to produce electricity (mainly). Therefore from that definition, the correct answer is: All materials that form from the remains of living organisms.

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.

9. Scientists who study ancient marine life forms usually obtain fossils not from the sea floor, but from areas that were once
undersea and have been uplifted onto the continents. Why?
Answer:
because of the constant change of the earths surface
Explanation:
hope i was able t help you out :)
The fossils have been defined as the impressions of the dead animals and plants in the rock strata. It is found in the areas that were undersea due to the constant movement of plate tectonics.
What is plate tectonics?Plate tectonics is defined as the structure that is present in the crust and the upper mantle that is defined by the lithospheric plates. These plates are made of hard rocks that show interactions and either move over each other or away from each other.
It shows the formation of the land and seas due to the alteration in the rock strata that results in convergence and divergence. The rock layers are also observed from the fossils that are dead imprints of the organism from ancient times.
They are found in the areas that were once under the sea but now are extracted from the continents. It has been due to the continuous movement of the plate tectonics that alters and modifies the earth's surface by the movement.
Therefore, plate tectonics is the reason that marine fossils under the sea are now found under the continents.

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.
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)
