Answer:

Basically land pollution is caused due to urbanization, mining, industrialization, landfill and improper waste disposal of agricultural chemicals . Major chemicals responsible are pesticides, lead, heavy metals, petroleum hydrocarbon etc.

Explanation:

Mining:

This creates large holes in the ground which in a long run causes soil erosion. Mining also removes the topsoil making teh soil barren land.It also releases harmful chemicals that contaminates the air and soil.

Industrialization:

The waste from the industry contains heavy metals in it. Which pollutes the urban soil as well as the cropland. Among all lead is most toxic that causes major part of land pollution.Also the chemicals makes the land infertile for making cultivation in it.

Main sources of land pollution are fertilizer use, overflowing landfills, deforestation, nuclear waste etc.

Explanation:

Land pollution is less visible when compared with water pollution but the effects of it are fatal. Several factors cause land pollution. In order to increase productivity agricultural sector uses chemical fertilizers and pesticides.  

These chemicals remain in the soil and the soil gets depleted of its fertility and the soil gets poisoned. These chemicals may also get washed into nearby water sources polluting the water body as well. Overflowing landfills are also a major cause of land pollution.  

It is not always possible to recycle all the waste generated. The waste that is dumped in landfills causes land pollution.

Final answer:

One of the weaknesses of the Articles of Confederation was that Congress had no power to levy and collect taxes.

Explanation:

One of the weaknesses of the Articles of Confederation was that Congress had no power to levy and collect taxes. While Congress had the authority to coin and borrow money, it did not have the power to impose taxes on the states or collect revenue. This limitation made it difficult for the national government to fund its operations and fulfill its responsibilities.

1. There was just a single branch: There was only one branch of government because the Articles of Confederation established a unicameral legislature known as the Congress. This absence of partition of abilities was a shortcoming since it focused an excess of force in one body.

2. It was impossible to make laws: This is an inadequate choice. It appears to allude to the way that under the Articles of Confederation, Congress had the ability to make regulations, however it missing the mark on ability to successfully uphold them. This shortcoming made it challenging to lay out and keep up with the rule of law all through the country.

3. Laws could not be enforced: As previously stated, Congress lacked the authority to enforce its laws. This shortcoming brought about an absence of power and prompted a breakdown in policing, it trying to keep everything under control and resolve questions.

4. Congress lacked the authority to impose and collect taxes: This is a substantial shortcoming of the Articles of Confederation. The focal government missing the mark on power to force and gather charges from the states. This restricted the public authority's capacity to raise income and asset its tasks actually.

Congress's inability to levy and collect taxes was a weakness of the Articles of Confederation; the power to maintain an army was not a weakness.

Among the various limitations of the Articles of Confederation, the inability of Congress to levy and collect taxes was a major weakness. The Articles only allowed Congress to request money from states, rather than impose taxes directly. Moreover, without the power to enforce laws, the federal government under the Articles had to rely on the states to execute its decisions, often leading to inefficiency and lack of uniformity. However, contrary to the given options, Congress did have the ability to create and maintain an army and a navy, regulate trade and commerce with foreign nations and among the states, declare war, and conduct foreign relations, which was not a weakness as implied by one of the choices. The national government's significant lack of enforcement powers and its inability to impose taxes made governing difficult and were rectified in the subsequent U.S. Constitution.

Therefore, the statement implying that Congress had no power to levy and collect taxes is NOT a weakness of the Articles of Confederation, but in fact, it was a prominent weakness that the national government faced during that time.

Explanation:

4) actively transport water molecules out of  its cell

Active transport is a mediated process that requires an energy input and the use of specialized membrane proteins to move against the concentration gradient. These proteins require energy in the form of adenosine triphosphate or ATP in order to facilitate necessary conformational changes to the large protein molecules to alter the spatial location of the molecule. For instance, with Na+, K+ pumps in cell membranes.

The paramecium would need to move the water molecules against their concentration gradient, out of the cell. Thus it would need to use active transport to pump water out and maintain its osmotic balance.

Final answer:

Density, which is mass per unit volume, affects how slowly or quickly a liquid flows. Denser liquids, with a higher mass to volume ratio, flow slower than less dense liquids.

Explanation:

Density is defined as mass per unit volume and is a crucial factor in determining how fluids flow. The density of liquids is typically higher than that of gases because the molecules in liquids are more closely packed together. Consequently, denser liquids tend to flow slower than less dense ones due to increased intermolecular attraction and resistance to movement.

To calculate density, the formula is density = mass/volume. Applying this to the statement that 'the denser a liquid, the slower it flows', it can be inferred that if we have two liquids, the one with a higher mass to volume ratio will be denser and hence, will flow slower.

For example, if we have two liquids with the following properties:

Liquid A will have a density of 2 g/cm³, whereas Liquid B will have a density of 1.5 g/cm³. Hence, Liquid A is denser and will flow slower than Liquid B.

Liquid A flows slower. Hence the correct option is a.

The density of a liquid is a crucial factor influencing its viscosity and, consequently, its flow characteristics. Density is determined by the ratio of mass to volume, and a higher density generally corresponds to a slower flow. In the provided data, Liquid A has a mass of 18 units and a volume of 10 units, resulting in a density of 1.8 units. In contrast, Liquid B has a mass of 8 units and a volume of 20 units, giving it a lower density of 0.4 units.

The significant difference in density indicates that Liquid A is denser than Liquid B. According to the relationship between density and viscosity, denser liquids exhibit higher viscosity, leading to slower flow rates. Therefore, the conclusion is that Liquid A flows slower than Liquid B due to its higher density, underscoring the critical role of density in determining the flow characteristics of liquids. Hence the correct option is a.

Complete question:

The denser a liquid, the slower it flows. The table below shows the mass and volume of two different liquids.

B 8 20

Which of the two liquids flows slower?

A: Liquid A flows slower.

C: They both flow equally.

D: This cannot be decided.

Answer:

B) Na+

Explanation: Na+ molecule is polar, oxygen and carbon dioxide are nonpolar molecules. The cell membrane is a phospholipid bilayer made up of lipid molecules with polar and nonpolar ends. Since it is a bilayer, two phospholipid layers are arranged, one on the other in such a way that one faces the back of the other. The non polar ends are away from outside and inside of the cell, while  the polar ends faces towards all the molecules inside and outside the cell.

Since polar-polar molecules repel each other, Na+ can't pass through the cell membrane easily. So it uses the proteins attached the cell membrane inside and outside to transport such molecules by using energy in terms of ATP.

Answer:Use a greater number of plants

Explanation:

A biology student wanting to study how the amount of light affects the growth of aquatic plants over the course of a week should opt for plants that have higher growth rate and choose more number of plants.

These are the plants which grow in water and these are accompanied by the water as their habitat.  

Watery plants have thick cuticle covering on their plants where the waxy covering on their part help to minimise the damage they can cause to plants.

Ensuring that all the plants  should get equal amount of light along with equal amount of nutrition along with equal conditions without any change in the experiment setup.

Taking up more number of plants will help to record in more and have a maximum of result without any much of exceptions. These kind of instructions will help the student in fetching up the positive result.

Therefore, It is wiser to give equal conditions to the plant along with more number of plants to be taken.

Answer: Glycogen

Explanation:

The energy in the human body is stored in the form of glycogen. In human beings the glycogen is stored primarily in the liver and muscle cell.

In liver the glycogen can make upto 5-6% of the organs fresh weight. and can store 100-120 grams of glycogen in it.

Glycogen is released slowly from the liver when the body is starving or the blood glucose is being consumed by the body.

Then there is a need that the stored glycogen is used by the rest of the cells.

Glycogen is the carbohydrate that is used for energy storage in the liver. It's a complex polysaccharide that is broken down into glucose for immediate energy when needed.

The carbohydrate used for energy storage in the liver is glycogen. Glycogen is a complex polysaccharide that serves as the main form of energy storage in animals, especially in the muscles and liver. When the body needs energy, it breaks down glycogen into glucose, which can be used for immediate energy or sent to the body's cells for use in cellular respiration. This makes glycogen a crucial factor in maintaining the body's energy balance.

Answer:

By experimentation and observation

Explanation:

For ATP production in the electron transport chain.

Hydrogen atoms contain 1 proton and 1 electron while being devoid of neutrons. When they lose their electron they form an ion or H+, a particle carrying a unit of positive charge. At the mitochondrial membrane, the outer membrane freely allows for the passage of H+ while the inner membrane does not.  Mitochondria require H+ concentration gradients to produce ATP; i.e. high concentrations of  of H+ in the intermembrane space and low H+ within the mitochondrial matrix.  

The H+ being pumped outside the mitochondrial matrix leads to increased H+ within the intermembrane space, due to its high permeability.  This forms a gradient where there is a differential in the number of protons on either side of the membrane the protons flow or re-enter the matrix through the enzyme ATP synthase, which makes the energy storage molecules of ATP from the reduction of ADP and inorganic phosphate, Pi.

Further Explanation:

During respiration in the mitochondria, oxidative phosphorylation occurs. This  describes a process in which the NADH and FADH2 made in previous steps of respiration process give up electrons in the electron transport chain these are converted it to their previous forms, NADH+ and FAD. Electrons continue to move down the chain the energy they release is used in pumping protons out of the matrix of the mitochondria.

This forms a gradient where there is a differential in the number of protons on either side of the membrane the protons flow or re-enter the matrix through the enzyme ATP synthase, which makes the energy storage molecules of ATP from the reduction of ADP. At the end of the electron transport, three molecules of oxygen accept electrons and protons to form molecules of water.

Final answer:

The electron transport chain pumps H+ ions across the mitochondrial membrane using energy from high-energy electrons, creating an electrochemical gradient used to drive ATP synthesis through a process called chemiosmosis.

Explanation:

The electron transport chain in mitochondria plays a pivotal role in cellular respiration by using the energy from high-energy electrons to pump H+ ions across the inner mitochondrial membrane. This process creates an electrochemical gradient, which is essential for ATP synthesis. High-energy electrons are donated by NADH and FADH2 and move through a series of protein complexes within the inner membrane. As electrons pass through the electron transport chain, they go from a higher to a lower energy state, which releases energy used to transport H+ ions against their concentration gradient from the mitochondrial matrix to the intermembrane space.

The accumulation of H+ ions in the intermembrane space generates a significant electrochemical gradient, comparable to water pressure behind a dam. This gradient represents stored energy that, when released through ATP synthase, an integral membrane protein complex, drives the synthesis of ATP. This diffusion of H+ through ATP synthase down their concentration gradient and the associated production of ATP is known as chemiosmosis.

When a household installs a dual flush toilet, the water is mainly conserved by limiting its consumption and thus eliminates the unnecessary loss of water.

Explanation:

A dual flush toilet is similar to a standard toilet but includes some water conserving features. It is an effective way to reduce the amount of water used in flushing . It has two buttons to select two different flush settings, one for the liquid waste and the other for solid waste. Normally less water is needed to get rid of liquid waste than solids. Some models of dual flush toilet system reuses the water in the hand washer for flushing. Standard toilets use siphoning action, where a siphoning tube is used to drain the waste. While flushing, a large volume of water enters the toilet bowl which fills the siphon tube and siphon pulls the waste and water down the sewer pipe. The siphoning action stops, when the bowl emptied and air enters the tube producing a gurgling sound. Dual flush toilet has a large hole at the bottom of the bowl and a wash down flushing design to push the waste down into the drain. This system needs less water per flush as no siphoning action is required. Also the waste is easily drained out of the bowl because of the large hole at the bottom of the bowl. In a dual flush toilet, the liquid waste flush utilizes only half the amount of water than the solid waste flush. The main disadvantage of a dual flush toilet is that it is more expensive than a normal toilet..

Metabolic pathways involve a series of biochemical reactions converting substrates to final products through anabolic and catabolic pathways.

Metabolic pathways are a series of sequential biochemical reactions that convert a substrate molecule through a series of metabolic intermediates to yield a final product. Anabolic pathways build complex molecules from simpler ones, requiring energy, while catabolic pathways break down complex molecules into simpler ones, producing energy. This balance between building (anabolism) and degradation (catabolism) constitutes metabolism.
