You are called to investigate a lake in your home town, where the residents fear that a broken pipe from the local sewage treatment plant has turned the formerly pristine lake eutrophic. You test the water and find very low levels of oxygen. What stage of euthrophication is this lake in?
Answer:
The correct answer is - The decomposers decompose dead algae and plants which take up most of the oxygen.
Explanation:
Eutrophication is taken place when there is a high amount of nutrients, minerals are present in a waterbody which allow algae to grow rapidly and cause depletion of oxygen due to the decomposition of dead organisms. There are the following stages in the eutrophication process:
- rapid growth of Algae and other plants
- due to algal bloom, the sunlight is blocked, and plants and organism start dying.
- The decomposers take up most of the oxygen by decomposition
- The animals start dying without oxygen

how are the processes of photos sentences and saw your respiration opposites of one another
Answer:
This question is not well structured. Based on understanding, the correct structure should be: How are the processes of photosynthesis and respiration opposites of one another?
They are opposite because photosynthesis uses the products of cellular respiration and vice versa.
Explanation:
Photosynthesis and cellular respiration are both metabolic processes that occurs within the cells of living organisms. Photosynthesis is the process where green plants synthesize food (sugar) in the presence of sunlight using carbon dioxide (CO2) and water (H2O). The general equation is as follows:
6CO2 + 6H2O → C6H12O6 + 6O2
On the other hand, respiration is the process whereby cells of living organisms synthesize usable energy (ATP) for use by breaking down glucose (C6H12O6) in the presence of oxygen. The equation is as follows:
C6H12O6 + 6O2 → 6CO2 + 6H2O
Based on the observation of the reactants and products of each process, it can be realized that the PRODUCTS of one process is the REACTANTS of the other. In other words, photosynthesis makes use of CO2 and water as REACTANTS, which are the PRODUCTS of respiration while cellular respiration uses glucose and oxygen as REACTANTS, which are PRODUCTS of photosynthesis.

What is the rule of proteins?
The function of a protein is determined by its shape. The shape of a protein is determined by its primary structure (sequence of amino acids.) The sequence of amino acids in a protein is determined by the sequence of nucleotides in the gene (DNA) encoding it.

Answer:
B
Explanation:I took the test if u need help follow me
Waves move faster in higher temperature and in solid phase because there is more energy and the particles are closer together.
What is meant by intermolecular force ?Intermolecular force is defined as the force of attraction experienced between the neighboring molecules in the same state.
Here,
During higher temperature and when in a solid phase, the waves exhibit movements very faster than in other phases.
This is because, when the temperature of the system is increased, the energy of the molecules in the system will be increased to a higher level. This energy formation is in the form of kinetic energy of the molecules.
Molecules in the solid phase have a greater intermolecular force of attraction with their neighboring molecules. Therefore, the molecules in the system will be more closer to each other.
As the kinetic energy of the molecules in the system increases, the molecules will start vibrating. These vibrating molecules induces the vibration to their neighboring particles, since they are closer together.
As a result, more and more highly energetic molecules are set to vibrate, which causes the wave to move faster in the system.
Hence,
Waves move faster in higher temperature and in solid phase because there is more energy and the particles are closer together.

Which two changes would increase the density of ocean water?
A. Increasing the amount of light that enters it
B. Decreasing its salinity
C. Increasing the amount of water that evaporates from it
I D. Decreasing its temperature
Answer:
The answer is simply D.
Explanation:
One factor that does affect density is the temperature. In general, most substances become less dense as temperature increases and more dense as temperature decreases.
The amount of water that evaporates from the ocean and the temperature are the two factors that influence its density. So options C and D are both true for this statement.
What is the effect of temperature on density?
The ocean water has more salts and minerals dissolved in it, so it is denser than normal fresh water. Some factors further decrease or increase the density of the ocean water. When the temperature drops, the water cools and ice forms. The ice is denser than the water, so it will sit below it.
As the temperature rises, the water evaporates, increasing salinity because more salts are present in the ocean water than in the water itself. The concentration of salt in the ocean determines the salinity of the ocean, and it can increase the density of ocean water when the concentration of salt is higher.
Hence, the amount of water that evaporates from the ocean and the temperature are the two factors that influence its density. So options c and d are both true for this statement.

g With respect to their 3' and 5' ends, the two polynucleotide chains of a double-stranded DNA molecule are:
Answer:
They are antiparallel
Explanation:
They are antiparallel because one strand of 3' faces the end of 5' of another strand and 5' end of one strand faces 3' end of another strand. Which indicate that 5 phosphate group faces the end of 3 hydroxyl group and they are of opposite directions to each other because it has opposite polarity with each other .

Penicillin-binding protein 2a, encoded by the medA gene, isn’t affected by beta-lactam antibiotics.
True
False
Answer:
The correct answer is - false.
Explanation:
Penicillin-binding protein 2a or PBPs are protein produced by bacteria that binds with the β-lactam antibiotics such as penicillin. They play role in the cell wall synthesis of bacteria by producing peptidoglycan by catalyzing the reaction.
β-Lactam antibiotics bind with the PBPs and cause the disruption to peptidoglycan cross-linking in the biosynthesis of the cell wall and ultimately lysis of bacteria takes place and cell death.
how energy is recycled in an ecosystem. how our atmosphere maintains its temperature. the importance of decomposers in an ecosystem. the one-way flow of energy in an ecosystem.
Answer:
The flow of energy in ecosystems is unidirectional or one-way.
Explanation:
Energy is the ability to do work. Energy flows in one direction in an ecosystem and is not recycled. This is because during the transfer of energy from one level to another, energy is lost. Most of the energy received from the sun by producers, plants, is lost as heat to the surroundings. The rest energy is converted by plants to produce food in the form of chemical energy.
Primary consumers feed on plants and secondary consumers feed on the primary consumers and so on up to quaternary consumers. However, at each level of energy transfer, some energy is lost as heat during respiration, some as unused or undigested materials, while some others are used for each organisms metabolic activities. About 90% of energy in a trophic is used at that trophic level. Therefore, only about 10% as much energy is available to organisms at each successive trophic level. Therefore, energy is not recycled in ecosystems.
Earth's atmosphere maintains its temperature by means of the earth's energy balance. This refers to how incoming from the sun and outgoing energy from the earth are in balance, thereby keeping earth's temperature constant.
Decomposers, are organisms such as bacteria, fungi, and small animals such as ants and worms that eat and decompose dead and waste organic matter and which recycle nutrients back into food chains making them available for plants use. Therefore, decomposers are an essential components of all ecosystems.

In three sentences or fewer, explain the difference between using geothermal energy to generate electricity and using the geothermal gradient to heat your home with an underground heat pump.
Answer:Tapping of geothermal energy to produce electricity is done on a larger scale compared to the tapping of the geothermal gradient using a geothermal heat pump. Harnessing geothermal energy is also reliant on geological conditions such as in the area of convection boundaries while geothermal gradient can be harnessed virtually anywhere on the earth surface.
