Answer:
The correct answers are "coal", "petroleum", "fuel cells" and "oil".
Explanation:
The energy solutions that release pollution into the air are coal, petroleum, fuel cells and oil. Coal was one of the first sources of energy to be used in the industry, the smoke generated from coal power plants is extremely dangerous and pollutant. Petroleum and its by products are very contaminant as well, producing high amount of carbon dioxide emissions as well as other greenhouse gases. Fuel cells are much cleaner than the other energy solutions however they still produce contamination into the air, specifically one ounce of pollutant for every 1,000 kW·h produced. Oil is also a contaminant of air, particularly when oil spills take place which are producers of carcinogens and aerosols.

Answer:
Primary succession.
Explanation:
Ecological succession refers to the changes involved in the species structure of a community that is established in a particular habitat over time. The succession is of two types: the primary succession and secondary succession.
When the succession takes place on the barren land then succession is considered primary succession.
In the given question, the moss invades and colonizes the rocks and breaks them into the soil. Here the moss species is known as the pioneer species and since the moss grows on the barren rock, therefore, is considered the primary succession.
Thus, primary succession is correct.
-Meiosis I produces two gametes that have exactly the same genetic make up.
-Meiosis II creates four daughter cells that are genetically different from one another.
-After meiosis I, two daughter cells with haploid number of sister chromatids are produced.
-Four gametes with haploid number of chromosomes and single chromatids result after meiosis II.
Answer:
after meiosis I two daughter cells with haploid number of sister chromatids are produced.
the parent cell in meiosis I is diploid and has 2n chromosomes.
four gametes with haploid number of chromosomes and single chromatids result after meiosis II.
Explanation:
Answer:
Meiosis II creates four daughter cells that are genetically different from one another.
After meiosis I, two daughter cells with haploid number of sister chromatids are produced.
Four gametes with haploid number of chromosomes and single chromatids result after meiosis II.
Explanation:
b) 36%
c) 66%
d) 58%
e) 24%
Answer:
Option C, 66%
Explanation:
Zoonotic pathogens are the ones which are transmitted from animals to human beings.
As per the study of world health organisation, nearly 61% of human diseases caused by pathogens are due to Zoonotic pathogens. This percentage has increased from last ten decades to 75%.
As per Center for Disease Control and prevention, more than 50% pathogens are Zoonotic pathogens
These pathogens can enter human being through various medium such as air, water, contaminated food, hand or mouth contact etc.
Some common examples of disease caused by zoonotic pathogens are -
Malaria, dengu, Typhoid etc.
Hence, option C is correct
Answer:
E. lack peptidoglycan, are the smallest free-living organisms AND have sterols in their membranes.
Explanation:
Mycoplasmas are also called pleuropneumonia-like organisms (PPLO) are the smallest free-living, prokaryotic organisms. They do not have a cell wall and is bounded by a plasma membrane which contains sterol.
Since cell wall is absent in them, they lack peptidoglycan. These are present in animals, plants, insects, soil and sewage. They grow better in the aerobic environment but can also live as facultative anaerobes.
Mycoplasma cause infection, affects cell metabolism, gene expression.
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.
