Answer:
1. Lipids perform three primary biological functions within the body: they serve as structural components of cell membranes, function as energy storehouses, and function as important signaling molecules.
2.The collection of proteins within a cell determines its health and function. Proteins are responsible for nearly every task of cellular life, including cell shape and inner organization, product manufacture and waste cleanup, and routine maintenance.
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.
Answer:
*~(￣▽￣)~*
Explanation:
"the definition of biomass is renewable energy source from Living or recently living plant and animal materials which can be used as file. for example of biomass :- plant material that produces electricity with steam.an example of biomass is animal fossil fuel".

Which system of the human body controls body loss and regulates body temperature?
Answer:
Our internal body temperature is regulated by a part of our brain called the hypothalamus. The hypothalamus checks our current temperature and compares it with the normal temperature of about 37°C. If our temperature is too low, the hypothalamus makes sure that the body generates and maintains heat.
Explanation:
Answer:
hypothalamus
Explanation:
It is the main organ which guides other organs to maintain body temperature

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.

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.
According to the scientific theory of atoms, which of the following statements best describes the location of electrons? A. in the nucleus of the atom B. both in the nucleus and around it C. outside the nucleus and often far from it, in the electron cloud D. outside the nucleus, yet very near it because they are attracted to the proton
Answer:
D. Outside the nucleus, yet very near it because they are attracted to the proton
Explanation:
Electrons are located outside of the nucleus of the atom, which is made up of neutrons and protons. In physics, the space they take up is informally referred to as the electron cloud. Protons and electrons are attracted to each other, because the positive electric charge of the protons is attracted to the negative charge of the electrons. This is why the electrons are very close to the nucleus.
The best statement that describes the location of electrons is D whichis Outside the nucleus, yet very near it because they are attracted to the proton.
What is electron?An electron is a negatively charged subatomic particle. It can be either free , or bound to the nucleus of an atom.
Electrons in atoms exist in spherical shells of various radii, representing energy levels. The larger the spherical shell, the higher the energy contained in the electron.
Thus, option "D" is correct.

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)

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.

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.
