Definition Of polar molecules and nonpolar molecules please?
Answer:
Non polar molecules are symmetric with no unshared electrons. Polar molecules are asymmetric, either containing lone pairs of electrons on a central atom or having atoms with different electronegativities bonded.
Explanation:
When things are different at each end, we call them polar. Some molecules have positive and negative ends too, and when they do, we call them polar. If they don't, we call them non-polar. Things that are polar can attract and repel each other (opposite charges attract, alike charges repel).

describe why rocks found at the bottom of the river are smooth and flat.Please in your own words,My teacher would get mad
The rocks found at the bottom of a river smooth and flat because those are collides with each other.
Explanation:
At the bottom of the river, the rocks which are found are very smooth and the shape of these rocks are flat because the rocks at the bottom collide with each other.
This results in the chipping off parts of the rocks and this results in the surface of the rock to become smooth and becoming flat. Moreover the sand found at the bottom acts as a sand paper creating resistance and smooth-ens the rocks at the bottom of the river.
Abrasion, which is the physical wearing away of a material by friction, is the process that results in the formation of smooth and flat rocks often found at the bottom of rivers.
What is Abrasion?Abrasion is the process of rubbing or scraping away a material, by rubbing against a rough surface or causing friction. This type of mechanical weathering can be brought about by a variety of things, including wind, water, snow, and human action. Rock, metal, plastic and wood are some of the materials that may be subject to abrasion.
This may result in material loss and modification of the appearance and texture of the surface. Natural features such as the smoothness of river boulders or the roundness of pebbles on a beach can also be the result of friction. Sandblasting, grinding and polishing are some examples of industrial abrasive applications.
Therefore, Abrasion, which is the physical wearing away of a material by friction, is the process that results in the formation of smooth and flat rocks often found at the bottom of rivers.

why do hurricanes weaken when they hit land

The role of DNA segment that do not code for proteins
Answer:
The non-coding regions of DNA are called introns. They are significant in evolution since they offer a great 'recipe' for recombination with genes/exons. Therefore, this offers variations among individuals on which natural selection could act upon to help a population adapt to changes in the environment. Introns also offer an additional step in gene regulation through the splicing of introns in making of mRNA.

The diagram shows the reproductive system of a plant.
Which of the following best describes the interaction that occurs between a plant's reproductive parts during self-fertilization?
Pollen is released from the stigma and is transferred to the anther. A pollen tube grows down from the anther through the filament and fuses with the ovule, where the sperm fertilizes the egg.
Pollen moves from the ovule up through the style and is released from the stigma. The pollen is transferred to the anther, where the sperm fertilizes the egg.
Pollen is released from the anther and is transferred to the stigma. A pollen tube forms and grows through the style. The pollen tube reaches an ovule within the ovary where the sperm fertilizes the egg.
The correct answer is pollen is released from the anther and is transferred to the stigma. A pollen tube forms and grows through the style. The pollen tube reaches an ovule within the ovary where the sperm fertilizes the egg.
This option correctly defines the interaction that occurs between a plant's reproductive parts during self-fertilization as it explains the pollination process and fertilization, when pollen grains are released then are transferred to the stigma the pollen tube is there that reaches ovule and the sperms fertilize an egg.
What is pollination?
Transfer of pollen from anther to the stigma of plants. Pollen is released from the anther and is transferred to the stigma. A pollen tube forms and grows through the style. The pollen tube reaches an ovule within the ovary where the sperm fertilizes the egg.
Thus it is clear that the answer explained above is correct describes the interaction that occurs between a plant's reproductive parts during self-fertilization.

cause changes in other Earth systems.
Answer:
interaction in the Earth's biosphere cause the change in other Earth system as the biosphere and atmosphere are dynamic, constantly reflecting these interaction. and Biosphere-Atmosphere Interactions focuses on the sources and sinks of greenhouse gases (GHGs), air pollutants, particulate matter, water, and energy between the Earth's surface and the atmosphere.
The Earth's biosphere is closely interconnected with other Earth systems, such as the hydrosphere (water), atmosphere (air), and geosphere (land). Changes in one part of the Earth's biosphere can have significant impacts on other Earth systems, and vice versa
What is a biosphere?Biosphere means interactions with each other and their physical environment.
For example, changes in land use, such as deforestation or urbanization, can affect the Earth's water cycle and climate. Deforestation, for example, can lead to increased runoff and erosion, which can alter the availability and quality of water in an ecosystem. Deforestation can also lead to an increase in atmospheric carbon dioxide, as trees and other vegetation absorb and store carbon dioxide during photosynthesis. This can contribute to global warming and climate change.
Similarly, changes in the Earth's climate, such as an increase in temperature or a change in rainfall patterns, can affect the biosphere. Warmer temperatures can lead to the range expansion of certain species and the loss of habitat for others. Changes in rainfall patterns can affect the availability of water for plants and animals, which can lead to changes in the distribution and abundance of species in an ecosystem.
