What is Air pollution?
Release of chemicals into the atmosphere that are harmful to both human health and the health of the entire planet is referred to as air pollution.
Globally, air pollution causes up to seven million deaths annually, according to the World Health Organization (WHO). Currently, nine out of ten people breathe air that is more polluted than what is considered safe by the WHO, with those in low- and middle-income nations suffering the most.
In the US, the Clean Air Act, passed in 1970, gives the Environmental Protection Agency (EPA) permission to protect public health by controlling the emissions of these dangerous air pollutants.
Therefore, Air pollution is caused by both human and natural occasions. Natural actions like volcanic eruptions, forest fires and wind erosion are examples of how nature pollutes the air is a false statement.

Seeds can grow into which of the following types of plants?
Answer:
Seed can be grow on both types of plants sometimes in monocot and sometimes dicot plants is is available in all plants when gynoecium and andrcium mate then formation of seed takes place
Final answer:
Seeds can develop into gymnosperms, such as conifers, gink-gos, that produce seeds, or angiosperms, which are flowering plants that include trees, vegetables, grasses, and decorative flowers.
Explanation:
Seeds can grow into various types of plants, which are primarily categorized into two groups: gymnosperms and angiosperms. Gymnosperms are plants like spruce, fir, and pine as well as gink-gos and cy-cads that produce na-ked seeds not enclosed by fruit.
On the other hand, angiosperms are flowering plants and they include a variety of species from broadleaved trees such as maple, oak, and elm, to vegetables like potatoes, lettuce, and carrots, as well as grasses and ornamental flowers like roses, irises, and daffodils. Seeds can also give rise to field crops such as wheat, forage and turf crops, and a wide range of vegetable and ornamental species, and tree and shrub seeds.

Characteristics of mitosis include
the most common kind of cell division
four daughter cells produced when parent cell divides
same number of chromosomes in each daughter cell as in the parent cell
different DNA in the daughter cell than in the parent cell
Final answer:
Mitosis is the process by which a single parent cell divides to produce two daughter cells that are genetically identical to each other and the parent cell, with the same number of chromosomes.
Explanation:
Characteristics of mitosis include:
The most common kind of cell division
Same number of chromosomes in each daughter cell as in the parent cell
Mitosis is a process where a single parent cell divides to produce two genetically identical daughter cells. This is known as somatic cell division.
During the stages of prophase, metaphase, anaphase, and telophase, the chromosomes are equally separated, ensuring that each daughter cell obtains an exact copy of the DNA, with the same number of chromosomes as the original cell. This is typically seen in diploid cells, which would have 46 chromosomes or 23 pairs in humans.
This ensures genetic continuity and is critical for growth, development, and repair of multicellular organisms. In contrast, meiosis results in four genetically distinct daughter cells with half the number of chromosomes.

all of these lists describe causes of global warming, EXCEPT:
a.)volcanoes, asteroid impact, changes in Earths plates
b.)energy production, burning fires, deforestation
c.)burning of fossil fuels,bchange in energy from the sun, energy production
d.) burning fossil fuels, change in energy from the sun, changes in Earths rotation.
Final answer:
Answer option a.) volcanoes, asteroid impact, changes in Earth's plates does not describe a cause of ongoing global warming. Recent warming is primarily caused by human activities such as energy production and burning fossil fuels.
Explanation:
The list that does not describe a cause of global warming is a.) volcanoes, asteroid impact, changes in Earth's plates. While volcanic eruptions can affect the climate by releasing large amounts of particulate matter and sulfur dioxide into the atmosphere, which can have a short-term cooling effect (known as the haze-effect), they are not a significant ongoing contributor to global warming.
Asteroid impacts are extremely rare and not a current factor in climate change, while changes in Earth's plates are geological processes affecting the Earth's surface and do not directly influence the atmospheric conditions that lead to global warming. The primary causes of recent global warming include energy production, burning of fossil fuels, and deforestation, which elevate levels of greenhouse gases in the atmosphere, thereby increasing the greenhouse effect and raising global temperatures.

If a force of 40 newtons moves a cart a distance of 9 meters, the work done is Nm. If the same force moves the same cart three times that distance, the work done is Nm.
Answer:
1. 360 Nm
2. 1080 Nm
Explanation:
Work done is a product of the force and the displacement.
Work= Fd where F is the force and d the displacement.
For scenario 1 where distance =9 meters the work done=
40 N×9 m= 360 Nm
For scenario 2 where distance= 9×3 =27 m the work done =
40 N × 27 m = 1080 Nm
Explanation:
It is given that,
Force acting on the cart, F = 40 N
Distance, d = 9 m
Work done is given by :
[tex]W=F\times d[/tex]
[tex]W=40\ N\times 9\ m=360\ J[/tex]
If the same force moves the same cart three times that distance, d' = 3 × 9 = 27 m. Now work done is given by :
[tex]W'=F\times d'[/tex]
[tex]W'=40\ N\times 27\ m=1080\ J[/tex]
Hence, this is the required solution.

How does the temperature of water change if you heat it after it has already reached the boiling point?
A. it does not change
B. it increases
C. it decreases
D. it increases then slowly decreases
Answer:
A. it does not change
Explanation:
the temperature of water does not change if you heat it after it has already reached the boiling point
after boiling point the temperature becomes constant and the heat energy supplied is used for vaporization .
Answer:
A. it does not change
Explanation:
This is because when water is heated to its boiling point of 100degrees celsius, more energy is usually needed to convert the liquid to gas so the additional heat helps in this conversion.
Water temperature doesn’t change when it reaches the boiling point till all the water evaporates into the atmosphere. When there is no more water, the temperature increases according to the nature of the container.

How do mutations lead to variation
Answer: Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
Answer:
The mutations cause genetic differences in a population, which causes the genetic variability, since the population is no longer homogeneous.
Explanation:
Mutations are random changes in DNA, which determine the appearance, behavior and physiology of organisms. These changes in DNA are primarily responsible for genetic variability between individuals in a population, and they occur most often in natural ways, when DNA does not replicate correctly. Changes in DNA can also be caused by having external sources, such as your exposure to chemicals or radiation.
