Explanation:
some of the advantages of inorganic farming.
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

Which graph shows the presence of nitrogen-fixing bacteria in the soil
Answer:
2
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.

Our experiment was to keep one seedling set in a light place and the other set in a closed cardboard box. So my question is to explain why it is important to keep one set of seedlings in the light. I hope to get a perfect answer
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. How are populations of chimpanzees affected by slash and burn agriculture? 2. Which features of chimpanzees make them more disadvantaged than other primates?
Answer:
1. Slash and Burn agriculture refers to a technique of farming that requires plants in a forest or woodland to be decimated to create a cultivable expanse of land.
Some of these plants are usually homes to wild chimpanzees. The more they are cut down, the deeper into the forests they would migrate, that's if they ever find a place like it.
2. When compared to the other primates such as monkeys, baboons, etc their larger body size, puts them at a disadvantage. This is because when they are placed in a restricted space, they need more food which in turn translates to increased height and weight.

Angelina is learning how to build circuits. She starts by connecting a light bulb to a battery with copper wires. In her studies, she reads that the current flows due to a difference in potential energy in the system. Which statement describes what is happening to cause current to flow? A. Voltage is when current flows from lower to higher potential energy. B. Voltage is when current flows from higher to lower potential energy. C. Amperes is when current flows from lower to higher potential energy. D. Amperes is when current flows from higher to lower potential energy.
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.
What is voltage?
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).
What is Amperes?It is a unit that we use to measure the intensity of the current.

In a sample of double-stranded DNA, 30% of the nitrogenous bases are adenine (A).
What percentage of the nitrogenous bases in the sample are thymine (T)?
Choose 1 answer:
A. 20%
B. 30%
C. 60%
D. 70%
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.
For children who do not have galactosemia, what are their possible genotypes for this trait?
a pedigree chart for the inherited genetic condition galactosemia
heterozygous
homozygous dominant
homozygous recessive
no inheritance for this trait
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.
Answer:
its heterozygous and homozygous dominant

how to ecosystem services affect human sustainability
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.
