Answer:
stages of the nitrogen cycle
1. Nitrogen-fixation
Legume plants such as peas, beans and clover contain nitrogen-fixing bacteria. These bacteria live in swellings in the plant roots called nodules. Nitrogen-fixing bacteria convert nitrogen gas from air into a form that plants can use to make proteins.
Free-living nitrogen-fixing bacteria are also found in the soil. When they die the nitrogen they have fixed into their biomass is converted into ammonium.
2. Feeding
Animals consume plant protein, digest it using specific enzymes and absorb the free amino acids.
3. Production of nitrogenous waste products
Animals cannot store excess protein in their bodies. They break it down and turn it into waste products and excrete them from their bodies.
4. Decomposition
Decomposers (some free-living bacteria and fungi) break down animal and plant proteins (from dead organisms) and nitrogenous waste products to release energy. As a result of decomposition nitrogen is released into the soil in the form of ammonium.
5. Nitrification
A group of free-living soil bacteria called nitrifying bacteria convert ammonium into nitrates in order to obtain energy.
6. Uptake of nitrates
Non-legume plants absorb nitrates from the soil into their roots and use the nitrates to produce their proteins.
7. Denitrification
This is when bacteria in the soil convert the nitrate back into nitrogen gas which then gets released back into the atmosphere.
Nitrogen-fixing bacteria take nitrogen gas from the air and transform it into a form that plants can use to build proteins.
Nitrogen-fixing and nitrogen in proteins:The nitrogen they have fixed into their biomass is transformed to ammonium when they die. In the soil, free-living nitrogen-fixing bacteria can also be discovered.
Nitrogen-fixing bacteria may be found in legume plants such as peas, beans, and clover. These bacteria dwell in nodules, which are swellings in the plant roots. Nitrogen-fixing bacteria transform nitrogen gas from the air into a form that may be used by plants to create proteins.

Answer:
The correct answer is - carrier.
Explanation:
If an individual posses an allele for the disease and does not affect by the disease such a person known as the Carrier of the disease. Such a person only posses one allele of the mutated gene or disease gene and a normal gene in their genotype.
They are mostly heterozygous for the particular trait or disease, therefore, do not get affected by the only allele of the disease gene. Generally, such a disease found in a recessive gene that causes it to masked in a person and carried to the next generation.

what is gene expression? What are the two stages of gene expression? What happens during those two stages?
Answer:
Gene expression is the process by which information stored in DNA is used to direct the synthesis of a specific gene product. This synthesis takes place in two stages: transcription and translation.
Explanation:
Gene expression is the process that makes it possible to obtain proteins from genes. Genes are nucleotide sequences of DNA that encode the information necessary for protein synthesis. This synthesis takes place in two stages: transcription and translation. Transcription takes place in the nucleus and in it one of the two strands that make up the double strand of DNA serves as a template for a specific sequence to be copied into a single stranded RNA molecule. Subsequently, this RNA leaves the nucleus and carries the message - the nucleotide sequence - to the ribosomes, hence the name of messenger RNA (mRNA). Translation is a cytoplasmic process in which the mRNA molecule is decoded to generate a specific chain of amino acids, called a polypeptide (the protein). The correspondence between nucleotides (mRNA) and amino acids (protein) is what is called the genetic code.
Which statement best describes energy transfer in a food web
(1) energy is transferred to consumers, which convert it to nitrogen and use it to make amino acids.
(2) Energy is transferred to converted into oxygen and transferred to consumers
(3) Energy from the sun is stored in green plants and transferred to consumers.
(4) Energy transferred to consumers, which use it to produce food.
Answer:
4)
Explanation:
when dealing with the food chain and how the energy transfer out through the food chain. you have to first think about the supporters of the food chain which are the consumers see the consumers consume as much as they can to be able to reduce the food when they able to reduce the food it balances out between the other supporters in the food chain for example the consumers, producers, decomposers
Explain how the changes in the trends for smoking may affect the occurrence of cardiovascular disease.
6 MARK QUESTION
Answer:
Smoking and cardiovascular disease
Smoking increases the risk of cardiovascular disease in several ways:
Smoking damages the lining of the arteries, including the coronary arteries. The damage encourages the build-up of fatty material in the arteries. This can lead to a heart attack or a stroke.
Inhalation of carbon monoxide in cigarette smoke reduces the amount of oxygen that can be carried by the blood.
The nicotine in cigarette smoke increases the heart rate, putting strain on the heart.
Chemicals in cigarette smoke increase the likelihood of the blood clotting, resulting in a heart attack or stroke.

1.) What is the percentage chance of producing a boy?
2.) What is the percentage chance of producing a girl?
Answer/Explanation:
There is a 50% chance of producing a boy. The is a 50% chance of producing a girl. To find percentage divide the desired factor by the possible outcomes. In this case, it 1 divided by 2 which is 0.5. Multiply the decimal by 100 to find the percentage.
1/2 = 0.5
0.5 x 100 = 50%
In a food chain, if 50,000 calories of energy are in the Ferns. How many calories of
energy will be available for the fish, which are the secondary consumers?
Answer:
500 calories
Explanation:
If ferns are primary producers and they only get 50000 calories then the next level of the food pyrimid will only get 1o percent of that. Next come primary producers which would get 10 percent of what the primary consumers would get so they would get 5000 calories. Next would be the secondary consumers which is the fish. they would get 10 percent of what the primary producers get so they would only be receiving 500 calories. I HOPE THIS HELPS
