Answer:

D. Open circuit

Explanation:

When a light bulb connects to an electrical power supply, an electrical current flows from one metal contact to the other. As the current travels through the wires and the filament, the filament heats up to the point where it begins to emit photons, which are small packets of visible light.

Answer:

When turning on a light, you are causing a closed circuit, which is a path that allows electricity to flow through it. In this case, the circuit is closed when the switch is turned on, allowing electricity to flow from the power source, through the light bulb, and back to the power source. This causes the light bulb to light up.

Option A, closed circuit, is the correct answer.

Answer:

The correct answer is - Eukaryotic DNA replication begins at multiple origins of replication, while prokaryotic DNA replication begins at a single origin of replication.

Explanation:

There are several differences in the prokaryotic and eukaryotic DNA replication as it takes place in the cytoplasm in prokaryotes whereas it occurs in the nucleus in the eukaryotes. The other difference is that it is a continuous process in prokaryotes but it occurs during the S phase only in eukaryotes.

In prokaryotes, the DNA replication begins at a single origin of replication in both directions and in eukaryotes, DNA replication starts at multiple origins of replication.

Option(B) Ureter is the correct option.

The ureter is a vital part of the urinary system in humans. It is a muscular tube that connects the kidneys to the urinary bladder. Each human has two ureters, one attached to each kidney, and they play a crucial role in the transportation of urine from the kidneys to the bladder.

The primary function of the ureter is to carry urine that is produced in the kidneys to the urinary bladder for storage before it is eliminated from the body through urination. The ureters accomplish this by using peristalsis, a wave-like muscular contraction, to propel urine along their length.

The ureters have a complex anatomical course. They originate from the renal pelvis, which is the funnel-shaped structure that collects urine from the kidneys. From there, they extend downward, crossing over the brim of the pelvis and passing behind the peritoneum, the membrane lining the abdominal cavity.

The efficient functioning of the ureters is essential for the proper elimination of waste products and maintenance of fluid balance in the body. Any obstruction or abnormality in the ureters can lead to conditions like kidney stones, urinary tract infections, or urinary reflux.

In summary, the ureters are muscular tubes that transport urine from the kidneys to the urinary bladder. They rely on peristaltic contractions to propel urine, and their structure and positioning help ensure unidirectional flow.

The products of photosynthesis are glucose and oxygen.

The process of photosynthesis involves two stages: the light reaction and the dark reaction.

During the light reaction, ATP and NADPH are formed. Light reaction gives rise to the formation of oxygen.

During the dark reaction(Calvin cycle) there is utilization of carbon dioxide along with ATP and NADPH formed during light reaction to form glucose.

mass = 44g

volume= 44L

1 liter = 1000cm^3

hence 44L = 44000cm^3.

Density = mass/volume

If the numbers are way under 1,000 it may indicate a hurricane is being formed. When the numbers are above 1,020 it indicates an area of strong high pressure.

The energy is related to the change of state represented by the model by: D. Atoms lose energy as a gas changes to a liquid.

A model of the transition from a gas to a liquid is shown in the accompanying image. It demonstrates how atoms or molecules change from being widely scattered as in a gas to being concentrated as in a liquid.

The atoms in this process move from a higher-energy state  to a lower-energy state releasing or losing energy in the process. The most common kind of energy loss is heat.

The example of elemental carbon is diamond and it is pure form of carbon. Thus, option A is correct.

Elemental carbon is pure form of carbon and it does not contain other elements and present in natural form. Due to this reason it is known as elemental.

In elemental form pure atoms are not attached to any other atom. Example is diamond which is allotrope of carbon in which there is only carbon atom attached to each other.

Methane and proteins are compounds consist of a combination of carbon and other elements and they are not come in category of elemental carbon.

Therefore,the example of elemental carbon is diamond and it is pure form of carbon. Thus, option A is correct.

Explanation:

To systematically investigate the yellowing of the plant's leaves, you can follow these steps:

1- Observation: Observe and note that after five days in the room, most of the plant's leaves have turned yellow.

2- Question: Ask yourself, "Why did the leaves of the potted plant turn yellow after being kept in the room for five days?"

3- Hypothesis: Make an educated guess about the possible cause of the yellowing. For example, you could hypothesize that the lack of sunlight in the room caused the leaves to turn yellow.

4- Experiment: Design an experiment to test your hypothesis. Place another potted plant in a different room with similar conditions but with sufficient sunlight.

5- Data collection and analysis: Record and compare the condition and color of the leaves in both plants after five days. If the plant with sunlight has green leaves while the one in the room still has yellow leaves, it supports your hypothesis.

6- Conclusion: Based on your observations and the results of the experiment, conclude that the lack of sunlight may be the cause of the yellowing of the plant's leaves.

By following these steps, you can systematically ask the right questions, form a hypothesis, conduct an experiment, and reach a conclusion using the scientific learning process.

Hope it helps!!! :)

A systematic method to ask the right questions, make educated guesses, conduct scientific experiments, and arrive at a conclusion is to follow the scientific method as follows:

A hypothesis could be; The yellowing of the plant's leaves is a result of reduced exposure to sunlight.

The yellowing of leaves in a potted plant kept away from sunlight is primarily due to a process called chlorosis which is the loss or reduction of chlorophyll in plant tissues.

When a potted plant is kept away from sunlight or receives insufficient light, the plant is unable to carry out photosynthesis. Consequently, the chlorophyll content in the leaves decreases, and they start to lose their green color.

Answer:

The products of the reaction decreases

Explanation:

When the product are formed in a chemical reaction it leads to decrease in chemical reaction rate in a cell.

Some chemical reactions are fast and some are slow due to presence of different  factors.

The collision between the reactants specially at the reactive site of the molecule will be needed to complete the chemical reaction.

So larger the size of reactant slower be the reaction or even no reaction occur due to less collision.  

The more surface area of the particle lead to more collision and faster the reaction.

More Concentration of chemical reactants lead to faster the reaction rate. Higher the pressure of the reactant lead to faster the reaction rate.

Increasing in temperature can also lead the molecules move faster, average kinetic energy of the molecule can also increases.

This could happen through diffusion because, as there is a high concentration of neurotransmitters close to the diffusing axon and a low concentration nearer to the receiving neuron.

The synapse that connects the following neuron's axon and dendrite allows neurotransmitters to pass through. Neurotransmitters adhere to the dendrite's membrane. The binding permits passage of the nerve impulse through the receiving neuron.

When neurotransmitters are being released from the presynaptic cell, their concentration is at their peak. The neurotransmitter can easily diffuse across this small distance to the postsynaptic neuron because the synaptic gap between the presynaptic neuron and postsynaptic neuron is so small.

Usually, before making a drug analysis, hair must be washed to avoid considering external environmental drugs deposited on hair (the last option).

Once drugs incorporate into the hair, they bond to different components composing highly stable complexes that can not be altered for several years. In fact, drugs can remain in the hair for hundreds of years.
