Answer:
The five spheres of Earth are the geosphere, hydrosphere, atmosphere, cryosphere, biospheres.
The ocean is one environment that is comprised of both the hydrosphere and biosphere. The ocean, being nothing but water, serves as the whole known world to all marine life within, which serves as the biosphere component.
Mountainous environments are also made up of multiple spheres; including, but not limited to, cryosphere, geosphere, with a little bit of biosphere as well. Mountains--which are giant rock formations created by years of seismic activity--are mostly covered in snow near the peaks due to low temperature, which will melt at different points during the year. A small assortment of wildlife call these areas home, such as jackrabbits, white-tailed deer, mountain goat, bear, gray wolf, coyote, lynx, and wolverine.

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.

think about photosynthesis and cellular respiration
• identify what form carbon takes after the light-dependent reaction of photosynthesis
• identify what form carbon takes after cellular respiration
pls help
Explanation:
The Calvin cycle takes place in the stroma and uses the ATP and NADPH from the light-dependent reactions to fix carbon dioxide, producing three-carbon sugars—glyceraldehyde-3-phosphate, or G3P, molecules. The Calvin cycle converts ATP to ADP and Pi, and it converts NADPH to NADP+.

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)
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.

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:

What occurs when the air temperature is equal to the dew point temperature? A:The relative humidity is 100%, so evaporation occurs. B:The relative humidity is 100%, so condensation occurs. C:The relative humidity is 0%, so condensation occurs. D:The relative humidity is 0%, so evaporation occurs. Is it B?
Answer:
B
Explanation:
When the air temperature is equal to the dew point temperature, the relative humidity would be 100% and condensation occurs.
The dew point temperature is a temperature at which the air is saturated with water vapor and some of it begins to condense as liquid water. As the air temperature cools further, more and more water condenses as liquid water and this is essentially what constitutes precipitation.
The correct option is B.
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.

C. RNA moves the DNA code to the ribosomes for protein synthesis.
D. DNA makes proteins in the nucleus.
Answer:
RNA instruct dna to make protien
The statement (A) best summarizes the process of protein synthesis.
What is protein synthesis?
Protein synthesis is the process in which cells make proteins. It occurs in two stages: transcription and translation. Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus.
Moreover, protein biosynthesis (or protein synthesis) is a core biological process, occurring inside cells, balancing the loss of cellular proteins (via degradation or export) through the production of new proteins. Proteins perform a number of critical functions as enzymes, structural proteins or hormones.
Therefore, ribosomes are the sites in a cell in which protein synthesis takes place. Cells have many ribosomes, and the exact number depends on how active a particular cell is in synthesizing proteins.

Which process takes the most energy? a.) Heating 10 kg of ice to the melting point. b.) Heating 10 kg of water to the boiling point. c.) Melting 10 kg of ice at a constant temperature. d.) Turning 10 kg of water to steam at a constant temperature. e.) None of the above.
Answer:
d.) Turning 10 kg of water to steam at a constant temperature.
Explanation:
Heat energy is the energy absorbed or released by a body or an object due to temperature difference. It flows from a body or system of higher temperature to that of lower temperature.
When heat energy is applied to change the state or phase of an object, a lot of energy is required in the process. The major two types of heat flow involved for the process are: specific heat and latent heat.
Therefore in the given question, the process that requires most energy is turning 10 kg of water to steam at a constant temperature.
