For the last 30 years, human use of fertilizers has had a significant impact on the nitrogen
cycle. Which statement explains how fertilizers impact an ecosystem?
O Fertilizers increase the amount of fixed nitrogen available in the ecosystem.
O Fertilizers decrease the amount of nitrogen fixed by organisms living in the ecosystem.
O Fertilizers kill off important nitrogen fixing bacteria.
Fertilizers decrease the amount of fixed nitrogen available in the ecosystem.
Answer:
It's C
Explanation:
Hope this helped :)))
The fertilizers show a significant impact on the nitrogen cycle as the fertilizers kill off the important nitrogen fixing bacteria which are present in the soil. Thus, the correct option is C.
What is Nitrogen cycle?Nitrogen Cycle is a biogeochemical process through which the nitrogen present in the environment is converted into many different forms, consecutively passing from the atmosphere to the soil to the living organisms and back into the atmosphere after decomposition. It involves several processes including the nitrogen fixation, nitrification, denitrification, decay and putrefaction of the nitrogen compounds.
Intensive fertilization of the agricultural soils of normal soil can increase the rates at which nitrogen in the form of ammonia is volatilized in the environment and lost to the air. It can also speed the microbial breakdown of ammonium and nitrates in the soil which results into enhancing the release of nitrous oxide. In addition to this, excessive use of fertilizers also kills the nitrogen fixing bacteria present in the soil.
Therefore, the correct option is C.

1. Compare and contrast mitosis and meiosis. 2. What major event occurs during interphase?
Answer:
1.
contrast between mitosis and meiosis
Mitosis
- it takes place in somatic cells in multi cellular organisms in order to provide growth, however, in unicellular organisms it is reproductive division as well. is the means of reproduction in single-celled organisms. Other organisms use it for the growth of tissues (somatic cells)
- exact number of chromosome in offspring
- no recombination or crossing over
- no pairing found
- major phase: prophase, metaphase, anaphase, telophase
Meiosis
- takes place in sex cells to form gamete formation during sexual reproduction
- half of the chromosome number found in gametes of the parents thus, known as reduction division
- due to crossing over takes place recombination found.
The pairing of chromosomes takes place
- major steps:
Meiosis 1 – prophase, Metaphase, anaphase, Telophase, and
Meiosis 2: Prophase, Metaphase, Anaphase, and Telophase
2. Interphase takes place prior to both mitosis and meiosis which is divided into 3 sub phases-G1, S and G2 phases.
The major events are as follows:
G1- RNA and protein synthesis takes place and cell grows in size
S- DNA replication takes place, Centriole duplication occurs and synthesis of histone proteins.
G2- RNA and Protein synthesis continues.
What two major events occur during meiosis that give the new cells genetic variation
Genetic variation is increased by meiosis
Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote. Recombination or crossing over occurs during prophase.

Do you solar cells, wind farms, tidal power, hydropower and thermal energy will solve our future energy needs?
Yes, according to my point of view I strongly believes that solar cells, wind farms, tidal power, hydropower and thermal energy will solve future energy needs.
Which source of energy is common now a days?The most common energy now a days is coal and by burning fossils fuels, we are risking climate change as well as limiting our resources. Supplies won’t last forever especially at the rate we are going. By using sun, wind, and water as sources of energy, we have renewable energy which would not run out anytime as soon as we required. Those energy charges are low cost and solves pollution issues too.
Heat energy has been transferred from one place to another by three main processes and in convection, heat energy has been carried by the movement of particles of matter. In conduction, heat is transferred by particles vibrating. In radiation, heat is carried directly by electromagnetic waves.
Therefore, Yes, according to my point of view I strongly believes that solar cells, wind farms, tidal power, hydropower and thermal energy will solve future energy needs.

Some individuals can develop kidney failure after consuming fava beans. What is the biochemical rationale for this observation?A. A deficiency of glucose-6-phosphatase that resulted in failure to synthesize essential red cell membrane proteins.B. A deficiency of glucose-6-phosphate dehydrogenase that resulted in failure to maintain glutathione in a state that prevents destructive lysis of the red blood cell.C. A deficiency of transketolase that resulted in the failure to provide ribose for the DNA and RNA needed to repair red cells.D. A deficiency of transaldolase that resulted in the failure to maintain glycolysis in the red cells. E. A deficiency of sedoheptulose that resulted in the failure to maintain the integrity of the red cells.
The correct answer to the question is option B
A deficiency of glucose-6-phosphate dehydrogenase that resulted in failure to maintain glutathione in a state that prevents destructive lysis of the red blood cell.
The deficiency of Glucose 6 phosphate dehydrogenase is a genetic disorder,when certain foods are consumed,the deficiency symptom to the enzyme is triggered and one of such food is Fava beans.
in Fava beans, Vicine is found, and this Vicine is an alkaloid glycoside.
Vicine is an oxidant,and it is toxic by causing disease favisim in individuals.The individual being affected are the ones that have hereditary loss of the Glucose 6 phosphate dehydrogenase enzyme.
But favisim only occurs when Fava beans is ingested fresh, that is without cooking it.
Following this,there is the development of acute intravascular hemolysis within 4-24hours after the ingestion of the Fava beans,there might also be a fall in the hemoglobin content of the blood and this may result in fatal condition.
But in cases that are acute, that is case of hemolysis, blood transfusion is vital and also in the case is kidney failure, dialysis must be done.
The reason why blood transfusion is very necessary is because the blood transfused may not have red blood cells that are deficient of Glucose 6 phosphate dehydrogenase,also the cells can have normal lifespan in the blood circulation of the recipient.
This Glucose 6 phosphate dehydrogenase is vital because it is a metabolic enzyme of Pentose phosphate pathway and it is also important for the metabolism of red blood cells.It also gives red blood cells protection from oxygen species that are harmful and reactive.
Option A is a metabolic disease that is
inherited which results in accumulation of glycogen and fat in liver.
Option C is as a result of deficiency in thiamine and malnutrition.
Option D is as a result of mutation in transaldolase gene.
Option E is as a result of genetic mutation.

Which division has a single preganglionic neurons with many axon collaterals that forms 20 or more synapses with postganglionic neurons?
a. sympathetic motor division
b. parasympathetic motor division
c. sympathetic sensory division
d. parasympathetic sensory division
Answer:
i believe its c
Explanation:
A single sympathetic preganglionic fiber has many axon collaterals and may synapse with 20 or more postganglionic neurons.
The postganglionic axons typically terminate in several visceral effectors and therefore the effects of sympathetic stimulation are more widespread than the effects of parasympathetic stimulation.

How can the role of epigenetics in cancer be reconciled with the idea that cancer is caused by the accumulation of genetic mutations in tumor-suppressor genes and proto-oncogenes
Answer:
Epigenetic mechanisms control the activity of genes involved in DNA repair pathways and cell growth
Explanation:
Epigenetics can be defined as the study of the alterations in gene expression patterns that do not involve alterations in the DNA sequence. Epigenetic mechanisms include 1-DNA methylation, 2-histone modifications (i.e., methylation, acetylation, phosphorylation, ubiquitination, etc.) and 3-non-coding RNA pathways (microRNAs, long ncRNAs, etc). These epigenetic mechanisms work together to control gene expression patterns by activating or silencing genes at the level of transcription, in a mode that is dependent on the cell type and developmental stage. In consequence, the failure of the epigenetic mechanisms modifies the activity of genes which may be involved in DNA repair pathways and thereby it may lead to severe disorders including some cancers.
Which cellular structure in plant cells is most responsible for having less flexible animal cells
Answer:
The cellulose cell wall in plants
Explanation:
All eukaryotic cells, both plant and animals cells have a cell membrane which is an outer covering of the contents of the cell. Also plants and animals cells have many structures and cell organelles in common such as the mitochondria, the endoplasmic reticulum, ribosomes, golgi bodies, etc. However, plant cells have a more rigid structure than animals cells because of the presence of an extra structure known as the cell wall, covering their cell membranes.
The cell wall is a rigid layer that is found outside the cell membrane and surrounds the cell, providing structural support and protection. The cell wall is composed mainly of cellulose, but contains proteins as well as other polysaccharides too.
Another structure present in plants that serves to maintain the rigidity of the plant cell is the large central vacuole. The main role of the vacuole is to maintain turgor pressure by pushing the plasma membrane against the cell wall due to the pressure of fluids contained within it.

How does ground water relate to lakes or rivers?
All lakes and rivers are replenished by groundwater.
When ground water reaches the surface it can form lakes or rivers.
Groundwater can affect the size of lakes and rivers.
Lakes and rivers produce groundwater.
Answer:
When ground water reaches the surface it can form lakes or rivers.
Explanation:
Groundwater in valleys is often pushed under pressure by rainwater that falls on the nearby highlands. If the water table reaches the surface, a lake, a river, or a spring is formed. A spring in desert country is surrounded by plants that take advantage of the water supply, forming an oasis. Water now coming to the surface at oases in the Sahara Desert came from rain that fell on hills near the desert during the Middle Ages--eight hundred to one thousand years ago.
