Answer:
Natural selection is a process that leads to evolution. For example variation can lead to this. Say back then one giraffe had a long neck this variation had a chance of being passed down to their children. If it keeps getting passed down by natural selection because its helping the giraffe survive then more and more giraffes will have long necks. Over time if the trait is super beneficial it could lead to the evolution of all giraffes having a long neck.
Explanation:
I used the terms that go with natural selection. If its not correct im sorry i tried lol.
Answer:
Natural selection leads to evolution due to the way reproduction works. In the example of European moths during the industrial revolution, we can see this clearly. When the industrial revolution was going on, there was more pollution, hence darkening the skies and leaving ash. Moths, which before were white with occasional black spots dominated the area until pollution affected their environment. Whiter moths were eaten by birds who could easily see them against the black trees and skies. These moths could no longer reproduce, they were dead. Moths with more black could survive longer to reproduce because they were harder to see. As time went along, the moths turned mostly black, showing an example of evolution.

Answer:
Biotic -- Insects, Weeds, fungi, bacteria, etc
Abiotic -- Sunlight, water, CO2 levels, Salinity, Pressure, etc
Explanation:
Plant development and crop output can be significantly impacted by both biotic (such as weeds, insects, fungi, and bacteria) and abiotic (such as sunshine, temperature, rain, humidity, drought, salinity, air, soil, pollution, magnetic fields, etc.) variables.
What effect of biotic and Abiotic factor in plant growth?Temperature and moisture have a significant impact on the amount of organic matter that is available for use as food and plant production (primary productivity) (net primary productivity).
To support life, development, and reproduction, trees require sufficient amounts of water, heat, light, nutrients, carbon dioxide, oxygen, and other abiotic resources.

How do matters differ and what explains that differences?
What is matter?
~ Matter is something which all physical objects are believed to be made of -- it is a material substance that occupies space, possesses mass, and is made up mostly of atoms (basic unit of matter) which consists protons, neutrons, and electrons, that constitutes the observable universe.
The states of matter~ State of matter is the distinction or the difference in forms of matter we can observe in our daily life. The 5 states of matter thus far are; solid, liquid, gas, plasma, and bose-einstein condensate.
DifferencesMatters differ in characteristics, appearance and compositions. Written here are the basic differences in 3 most fundamental states of matter.
Solid - a matter which composed of rigid and closely packed particles -- particles move only via vibrations. Has definite shape and definite volume.
Liquid - particles can move back and forth, not too tightly packed -- has definite volume but with no definite shape.
Gas - the particles in gas are relatively far apart compared to solid and liquid, they're moving fast back and forth/side to side, and bouncing nonstop. Gas neither have definite shape nor volume, and is way compressible than solid and liquid.

Which of these is the most likely consequence of rising petroleum prices?
A. Increased interest in public transportation
B. Falling transportation costs
C. Lower gasoline prices
D. Less demand for electric cars
Answer: Increased interest in public transportation
Explanation: got it right
Due to public transportation, more vehicles need more petroleum, leading to an increase in petroleum prices, hence option a is correct.
How are petroleum prices rising?Petroleum prices are likely to have risen as a result of both increased demand and worries about supply interruptions. Global demand for oil has been rising, exceeding any increases in supply and surplus capacity.
One major reason is that developing countries, particularly China and India, have been quickly rising. These economies have grown more industrialized and urbanized, contributing to an increase in global demand for oil.
This is because transportation costs will rise, raising the prices of numerous commodities. This is cost-push inflation, as opposed to inflation produced by increased aggregate demand excess growth.
Therefore increased interest in public transportation, leads to rising petroleum prices, hence option a is correct.
