Explanation:

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.

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.

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.

3. Decayed, ammonification

4. Denitrification

5. nitrite reductase

Explanation:

The nitrogen cycle refers to the series of processes that adds and removes nitrogen from the soil or atmosphere. The series of processes involved in nitrogen cycle are being described in this question as follows:

- Atmospheric Nitrogen (N2) is converted to NH3 (ammonia) in a process catalyzed by the enzyme NITROGENASE in a process called nitrogen-fixation.

- NH4+ (ammonium ion) is converted to NO2- (nitrite) and then NO3- (nitrate) in a process called NITRIFICATION.

- Atmospheric nitrogen (N2) is decomposed or broken down to NH4+ (ammonium ions) as a result of a process called AMMONIFICATION.

- Nitrate is converted to atmospheric nitrogen (N2) in a process called DENITRIFICATION.

- Nitrite conversion to ammonium ion (NH4+) is catalyzed by an enzyme called NITRITE REDUCTASE

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 .

Waves move faster in higher temperature and in solid phase because there is more energy and the particles are closer together.

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.

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.

''How long you will observe this type of problem in your life''

Explanation:

''What is your problem'' is the first question i will ask when a patient arrived at GNMH in order to fully know the condition of the patient. ''How long you will observe this type of problem in your life'' is the second question I will ask the patient, these two questions are enough for knowing the problem. After these two questions I will give him or her the suitable treatment for the removal of the disease or problem.

The question would be ''What is your problem'', ''How long you will observe this type of problem in your life''.

Explanation:

This means that water flows from where it is in a higher concentration to a place where it is in a lower concentration to try to equalize the concentrations of both solutions.

Osmosis is an example of diffusion when molecules tend to be evenly distributed in space.

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
