Answer:

B. Voltage is when current flows from higher to lower potential energy.

Explanation:

Voltage refers to the difference in electric potential between two points. Current in the wire always flow from higher potential to lower potential due to voltage. At the electric source, voltage of current is high but when it moves through wire, the amount of current decreases when it reaches to the other end of the circuit. This is because of the resistance present inside the wire which causes heat energy and some of the current is lost.

The correct answer is option B. Voltage is when current flows from higher to lower potential energy.

Voltage is the difference in charge, in this case, made by the electrons, that results in electrons flowing from a place of high concentration to one of low concentration. We call the flow of electrons current, and we measure voltage in Volts (V).

It is a unit that we use to measure the intensity of the current.

Answer:

Sugar

Explanation:

Photosynthesis is a process that certain organisms undergo. Plants, algae, and certain bacteria use this process to produce their own food. These organisms are called producers or autotrophs.

The equation for photosynthesis is:

carbon dioxide + water + light energy —-> glucose + oxygen

The plants turn carbon dioxide, water, and light energy from the sun into glucose and oxygen. The glucose, or sugar, becomes the food for the plant. The oxygen is the waste product.

The question asks us what is produced during photosynthesis.

Chloroplasts are not produced, but they are where photosynthesis takes place. Carbon dioxide is not produced, but it is used in the process. The correct answer is sugar. Sugar is produced, and it is the food for the organism.

All cells have these four parts in common: a plasma membrane, cytoplasm, ribosomes, and DNA.

Explanation:

Answer:

All cells share four common components:  

a plasma membrane, an outer covering that separates the cell’s interior from its surrounding environment

 cytoplasm, consisting of a jelly-like region within the cell in which other cellular components are found

DNA, the genetic material of the cell

ribosomes, particles that synthesize proteins. However, prokaryotes differ from eukaryotic cells in several ways.

Answer:

Explanation:

The graph that shows the presence of nitrogen fixing bacteria in the soil would be graph 2.

Nitrogen fixing bacteria are bacteria that are capable of converting atmospheric nitrogen into plant-usable nitrogen in the soil. The conversion is done in two stages;

1. First, atmospheric nitrogen is converted into ammonia.

2. Ammonium is converted into usable nitrate

Hence, the correct graph is the one in which the amount of atmospheric nitrogen decreases with a corresponding increase in the amount of ammonia. This would indicate the conversion of nitrogen into ammonia which is the first step in nitrogen fixation by nitrogen-fixing bacteria.

Graph 2 represents the presence of nitrogen-fixing bacteria in the soil.

This is because in this graph the concentration of atmospheric nitrogen (N2) is lower and the concentration of ammonium (NH4) is higher. The nitrogen-fixing bacteria converts or fixes atmospheric nitrogen that can't be absorbed by the plants into ammonium or nitrates which can be absorbed by the plants and make necessary amino acids for the body so we can conclude that graph 2 indicates the presence of nitrogen-fixing bacteria in the soil.

Answer:

To examine the importance of light to a plant's growth.

Explanation:

To give a background to this question, I will define a key term "Photosynthesis". Photosynthesis is a compound word made up of photo (which means "light") and synthesis (which means "to put together").

It is the process by green plants use sunlight to obtain nutrients from carbon dioxide and water.

The experiment us meant to examine the effect of deprivation of sunlight on a plant's growth.

Therefore, the essence of keeping one set of seedlings in the light is to compare if there is any difference in growth between the seeding kept in the dark cupboard and that kept in the light.

This enables us to conclude whether or not light is important for the growth of a plant.

1. Energy is often considered the “Fuel of Life”. Primarily, it is needed for maintaining basic

metabolism (maintenance energy). Any excess is then used for production of meat (growth)

and/or eggs (production). Fed too much energy, hens become overweight (excess growth)

leading to poor production. If fed too little energy, hens begin using protein to meet their basic

maintenance needs and egg production may be compromised. As is the case with most things

in life, balance is the key. This article is an attempt to provide a flock manager with some tools

to use when making decisions on feeding energy to a breeder flock. Some of the research

cited is not current and is in no way intended to be anything more than an example of the

thought processes that may be helpful when making difficult decisions about feeding.

Energy is essential to meet our most basic needs: cooking, boiling water, lighting and heating. It is also a prerequisite for good health – a reality that has been largely ignored by the world community.

2. Coal and diamond are two examples of carbon allotropes, where the carbon atoms are bonded together in different configurations. These structural differences result in very different material properties, such as hardness.

On its own, carbon cannot form diamonds under the surface of the Earth. Both coal and diamond are made primarily from carbon, but their chemical structures are significantly different. Coal is formed from highly impure carbon that often contains elements like oxygen, selenium, hydrogen, nitrogen and sulfur.

Answer:

With the use of pesticides, farming can be faster and it also detracts insects and weeds

Answer:

One advantage inorganic fertilizers offer is that they are fast acting. These nutrient-rich salts dissolve quickly and are immediately available to the plants depending on them to provide essential nourishment in the form of nitrogen, phosphorus and potassium.Organic fertilizers usually contain plant nutrients in low concentrations. Since many chemical/inorganic fertilizers are concentrated and very soluble, it's easier to apply too much and damage your plants. Fresh, non-composted manure can damage your plants as well, because some manure contains harmful amounts of salts

Answer:

The correct answers are "heterozygous", and "homozygous dominant".

Explanation:

Galactosemia is a condition where people are not able to process the sugar galactose. People with this condition have one gene mutated, which does not allow the proper synthesis of the enzyme that breaks down galactose. Galactosemia is inherited as an autosomal recessive genetic condition, therefore, only children that are homozygous recessive develop the condition. Children that are heterozygous or homozygous dominant, will not develop galactosemia.

All systems work together to stabilize the body.

Explanation:

Certain systems work with each other in order to maintain homeostasis, which is essential for the body. For example, when blood circulates through the digestive system, it picks up nutrients absorbed by the body during its last meal. Additionally, blood carries oxygen taken in by the lungs. The circulatory system works with the respiratory system here to distribute oxygen to other parts of the body.

Answer:

30% thymine

Explanation:

If 30% of Adenine is present, it would be reasonable to assume that 30% of Thymine will be present, as the ratio between the two complementary nitrogenous bases will be roughly equal. Therefore, that leaves us with 40% between Cytosine and Guanine.

Answer:

Ecosystem services play important role in human sustainability. Ecosystem services include provisioning,regulating, supporting, and cultural.

Provisioning include production of food and water which is one of the essential requirement for human survival and provided by ecosystem in the form of plants or other animals. No food means no human life.

Regulating may include the control of disease and climate.Humans at different regions are susceptible to particular temperature and diversity in Climate provide required atmospheric condition for human survival. Climatic changes causes global warming which bring many diseases and temperature fluctuations that affect human sustainability. Diseases decreases human population and affect human susceptibility so ecosystem controls the diseases that increases chance of human survival. More diseases with no medicine may result into high mortality rate.

Supporting, such as oxygen production and nutrient cycles are important factors that support human sustainability because nutrients provide energy to humans to do work and oxygen is must for their living.

Cultural involve recreational and spiritual benefits. Recreational and spiritual benefits include regulation of physical and mental health and social interaction with  other people  that keeps a human healthy and happy for living a good life.

Hence, ecosystem services promote and affect human sustainability.
