what is plants?
what is biology?
Answer: Didn't quite understand but if you mean plant biology then, ' Plant biology is the lab science area of plant study although they may spend some time in the field collection samples and taking records of plants in their natural habitats. It requires not only an understanding of a plant's biology but also its chemistry. This will include its genetic coding.'

A radioactive material has a half-life of 30 days. You begin with 4 grams of radioactive material.
a. How much of the original is left unchanged after 90 days?
b. After 120 days?
Give explanation. Don't go.ogle.
Answer:
a. 0.5 grams b. 0.25
Explanation:
Just use the half-life formula(I linked it below)
a. 4(1/2)^90/30=1/2
b. 4(1/2)^120/30=1/4
A. 0.5 grams is left unchanged after 90 days.
B. 0.25 grams is left unchanged after 120 days.
What is Half life?The half-life of a radioactive isotope is defined as the time it takes for half of the radioactive isotope to decay. It is stable in specific radioactive isotopes. It is unaffected by circumstances. It is also independent of the initial amount of that isotope.
It can be find out by this formula:-
[tex]N=N_o (1/2)^n\\\\[/tex]
where, N= quantity of the substance remaining
[tex]N_o[/tex]= initial quantity of the substance
n= number of half lives
For above given example,
Given that radioactive element X has a half-life 30 days
Hence the number (n) of half-lives in 90 days
n=90/30
n=3
The amount N of radioactive element X left after n=3 half-lives with initial amount [tex]N_o[/tex]=4 gm
[tex]N=N_o (1/2)^n\\\\\\N= 4 (1/2)^3\\N= 4(1/8)\\N= 0.5 gms\\\\\\[/tex]
For 120 days, n=120/30
so, n= 4
Then,
[tex]N=4(1/2)^4\\N=4(1/16)\\N=0.25 gms[/tex]
Thus, A. 0.5 grams is left unchanged after 90 days.
B. 0.25 grams is left unchanged after 120 days.

Which is an advantage of safely using uranium as an energy source, rather 1 point
than using coal? *
Uranium produces energy without polluting the atmosphere, while burning coal can
increase the CO2 in the atmosphere.
Uranium reduces the amount of thermal pollution, while burning coal can increase the
amount of thermal pollution.
Uranium is the most cost-efficient energy resource, while coal is the most expensive
energy resource.
Uranium can be easily mined from deep within Earth, while coal is a hard resource to
mine from deep within Earth.
Which change would best aid a farmer in making the transition from
1 point
Answer:
While demand is increasing for uranium, there are both advantages and disadvantages to consider in this metal. The benefits include safer and more efficient nuclear power plants. The kind of energy that is produced is clean with no greenhouse gases and the cost of operating a nuclear power plant is inexpensive.

Accordingly, once you diluted the ammonia completely, it is suitable for disposal. You can pour the aqua ammonia down the kitchen sink, or flush it down your toilet. However, beware if you have a septic drainage system, the solution will proceed to mix with the water underground and pollute it.
The tilt of the Earth's axis and it rotation affect weather, because the ________ allows some latitudeds to be heated at a greater rate while Earth ________.
Answer:
Tilting of earth and Earth has four growing season.
Explanation:
The tilting of earth allows some latitudeds to be heated at a greater rate while Earth has four growing season due to this tiltation of earth. If there is no tilting of earth occurs, there will be no seasons. Earth's axis is tilted about 23.5 degrees from the plane of its orbit around the sun which greatly affect the weather of various parts of the earth so we can say that tilt of the Earth's axis and it rotation affect weather around the world.

Describe three ways that the growth of suburban populations would have affected land and aquatic ecosystems around cities.
Answer: The three ways the growth of suburban populations( urbanisation) would affect the environment include:
--> Insufficient water availability,
--> Waste-disposal problems, and
--> High energy consumption.
Explanation:
The growth of suburban population is also called URBANISATION. This is defined as the rapid growth of an urban area which occurred due to the movement of individuals from rural areas into the urban area. There are different reasons why individuals migrate to urban areas these include:
--> for a better access to health care services
--> for more education opportunities
--> To combat the problems of unemployment and
--> for better participation in political and social activities.
The three ways the growth of suburban populations( urbanisation) would affect the environment include:
--> Insufficient water availability: the increase in the urban population creates a high demand for water use both for industrial and domestic uses.
--> Waste-disposal problems, and
--> High energy consumption.

Deforestation, Water pollution, Introduction of invasive species
Explanation:
For ages, human beings have been altering the natural ecosystems and causing irreparable damages to nature. Development drove to an unmeasurable advance over new unpopulated areas.
Some of the principal human activities responsible for biodiversity loss are
• the uncontrolled use of unrenewable resources,
• overexploitation of renewable resources;
• land destruction for the mining industry, farming and cattle industry, buildings, and other infrastructures;
• the unplanned advance of cities, and opening of new roads to connect those cities.
All of them involving
deforestation and fragmentation of natural landscapes; water, air, and soil pollution, species loss, and reduction of biodiversity. Introduction of invasive species.And the growth of suburban populations is a frequent human activity causing an impact on nature. To mention a few ways in with this action might affect ecosystems, we can name the followings,
Deforestation:
The growth of suburban populations is indefectibly related to deforestation. New open areas are needed for buildings, roads, and service establishments, such as natural gas or water ducts, light, and others. There hardly exists planning about the cities´ growth and conscientious conservation of nature.
Water pollution:
Water is severely polluted while constructing buildings and roads. The wastes of materials used for construction, oil coming from transport and machinery, human wastes, among other sources of contamination reach the rivers or lakes, polluting them and altering the natural equilibrium.
Introduction of invasive species:
It is very common to use ornamental vegetable species, proceeding from other areas or countries to arrange the gardens, streets, and parks. These species might become invasive and uncontrollable, causing severe damage in native endemic species by competing for resources. The whole ecosystem structure changes.
Deforestation, water pollution, and the introduction of invasive species are some of the causes of biodiveristy loss.

Which of the following is a likely result of deforestation?
the amount of carbon dioxide removed from the atmoshpere is reduced.
Wind blows soil away because the plant cover has been removed.
Water runs off the land more rapidly and causes floods.
All the above.
Answer:
All of the above
Explanation:
Trees reduce carbon, if there aren't trees they can't reduce carbon, trees help hold soil together with their roots, and (I believe) trees help stop floods by slowing down erosion and keeping everything in place.
