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.

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.

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.

During the Carboniferous Period, what were largely responsible for regulating the climate on land masses? A. Land masses B. The glaciers C. The North and South Poles D. Large oceans
Answer:
D. Large oceans
Explanation:
During the Carboniferous period, the majority of the land masses were merged into one large supercontinent, with smaller landmasses being very close to it. This meant that there was one enormous ocean surrounding the supercontinent, but also one smaller one that was getting deeper into the land masses. The large Panthalassic Ocean had huge effect on the climate on Earth in this period. Because it was so large, it produced very large air masses, mostly warm and wet, causing a lot of precipitation, resulting in warm and wet climate in most of the planet. It was also an ocean that was capable of producing storms and waves much larger than anything we can see nowadays, managing to cause lot of damage along the coastlines of the supercontinent.
During the Carboniferous Period, glaciations and the formation of Pangaea played a major role in regulating the climate on land masses. The drier and cooler conditions led to significant ecological and evolutionary changes in plants and animals. The correct option is B.
During the Carboniferous Period, the climate on land masses was largely regulated by glaciations and the resulting cooler global climate. Towards the end of the Carboniferous, a trend toward a drier climate with evidence of glaciation and lowered sea levels is observed. These changes had significant impacts on the distribution and evolution of plant and animal life, favouring adaptations for drier conditions such as xerophytic leaves in gymnosperms and the development of eggs that could survive outside of water for vertebrates.
The development of a single supercontinent, Pangaea, further influenced the continental climate, creating arid inland regions due to the distant moderating effects of the large oceans. Glaciations affected the climate by contributing to the formation of land bridges between continents and altering the habitats and distribution of life on Earth.
Whats 2 examples of homologous structures?
Answer:
Homologous structures are those that share evolutionary and developmental origins. When discussing them one usually refers to those that have different uses in organisms. For instance the malleous and stapes bones in the middle ear of mammals are used to transfer sound whereas in most lizards these bonse are used in jaw articulation.
Other examples will be the forelimbs of a quadrupeds that includes the same bones as the human arm.
Another interesting example is the equivalent of one of the wrist bones in most mammals is used as a pseudo thumb in pandas.
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.

DNA replication is not a process that can cause speciation.
Speciation
The process by which new species are formed from the existing species is termed speciation.
Speciation Types
Allopatric SpeciationParapatric SpeciationPeripatric SpeciationSympatric SpeciationFactors Affecting Speciation
Genetic Drift- Genetic drift leads to the formation of new species by causing a population of organisms to be genetically distinct from the original population.Natural Selection- Natural selection is the process in nature by which organisms that adapt to their environment tend to survive and reproduce more than those less adapted to their environment.Geographic isolation- The populations of species are divided by geographic barriers. These geographic barriers may include rivers, water bodies, and mountains.Mutation- The accumulation of many small genetic changes in a population is known as mutations.Therefore, Option (D) DNA replication is the correct answer

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.
