Answer:
Burning fossil fuels
Explanation:
Greenhouse gases are the main human causes of global warming.They basically act like a warm blanket around the earth and trap heat. Causing the earth to get warmer and temperatures to rise.
The two main greenhouse gases we add to the air are methane and carbon dioxide.
The main source of carbon dioxide is the burning of coal,oil,gas and petrol(fossil fuels)in power stations.
We produce far more carbon dioxide than any other greenhouse gas. And its production has been on the rise since the industrial revolution.
So the burning of fossil fuels resulting in carbon dioxide is the main cause of global warming.

In a population of spiders there are three different sizes: small, medium, and large. ---The large spiders are easily seen by predators. ---Small spiders have a difficult time finding food. What will most likely happen to this population of spiders after many generations?
Answer: Over time the medium spiders will be most common out of the three.
Explanation: Because of natural selection the large and small spiders wil die leaving more medium spiders alive. So now the medium spiders can reproduce and make more medium spiders so there will be much more medium spiders compared the the small and large ones.

In his analysis of different species’ DNA, E.Chargaff discovered the base-pairing rules of DNA.
1.) Chargaff’s rules state: The amount of adenine is equal to ? and the amount of cytosine is equal to ? .
2.) if a sample of jellyfish DNA is 14% cyotsine, approximately how much adenine would there be in that same sample? Show your work.
Answer:
1. Thymine, Guanine
2. 36% Adenine
Explanation:
1. Edwin Chargaff, who proposed the complementary base pairing rule, stated in his rule that the amount of purine bases (Adenine and Guanine) is equal to the amount of Pyrimidine bases (Cytosine and Thymine). This means that, in a DNA molecule, the amount of adenine is always equal to Thymine (A=T) and the amount of Cytosine is equal to Guanine (G=C).
Also, the total amount of the four nucleotide bases that make up a DNA molecule is equal to 1 or 100% i.e. A+T+G+C= 100%
2. Based on the rule above, if a sample of jelly fish DNA contains 14% Cytosine, the amount of its complementary pair (Guanine) will also be 14%.
Hence, Cytosine and Guanine will collectively occupy 14+14=28% of the DNA.
To find the amount of the other two bases i.e. Adenine and Thymine, we subtract 28% from 100%
That is, 100 - 28 = 72%
If both Adenine and Thymine contains 72% and each must be equal, we divide 72% by 2 to get the amount of each.
Hence, 72/2 = 36% of Adenine and 36% of Thymine.
According to the question, Adenine will contain 36% in the Jellyfish DNA.

Soil at the shore of Lake Erie in Pennsylvania has a high sand and gravel content. Which of the following is a characteristic of this type of soil?
A) extreme acidity
B) rapid water drainage
C) extensive producer biomass
D) significant depth before hitting bedrock
Answer:
rapid water drainage
Explanation:
These are example of granular (sand and gravel)soils.They are more permeable to water, and therefore can not retain water molecules.They are non-cohesive soil,with high strength and capacity to withstand slope.
High acidity is not a characteristic feature of soil with sand and gravel.In addition, such soil lacks biomass therefore can not support plant growth. The soil type is not a yardstick to determine the dept of soil type.Consequently, rapid water loss due to porosity is the best option.

Sunlight enables plants to use water and carbon dioxide during photosynthesis to make and store sugar. Any animal that eats the plants can convert the sugar into the energy it needs to move from place to place. Which three types of energy are involved in this example?
Answer:
Solar energy, Chemical energy and Mechanical energy
Explanation:
Sunlight enables plants to use water and carbon dioxide during photosynthesis to make and store sugar:
The type of energy utilized here is solar energy. The energy from sunlight which is the solar energy is captured by the chlorophyll in plants enabling them use water and carbon dioxide to produce their own food.
Any animal that eats the plants can convert the sugar into the energy it needs to move from place to place.
The energy from the sun which is the solar energy is converted into chemical energy, and the animal that eats this plants gains some of this energy and converts it to mechanical energy, the energy needed to do work: motion energy e.g. moving from place to place.
Answer:
Light energy from sun
Chemical energy
Kinetic energy.
Explanation:
Light energy is gotten from sunlight which is use with carbondioxide and water to produce sugars.
The chemical energy is the substance that undergo chemical reaction to produce another substance. The light energy cause a chemical reaction that breaks carbondioxide molecules and water to produce sugars.
After the animal eat the food, it's get chemical energy and it's is converted to kinetic energy for movement.
Kinetic energy is the energy posses by a body in motion.

I require assistance. Oil is a fossil fuel used to run cars, heat up homes, and produce electricity. Oil can be removed from the bottom of the ocean through drilling. Drilling machines dig deep down into the Earth. When oil is found, pipes carry it to the surface. Sometimes, accidents happen that cause the oil to spill into the oceans. The oil can not only kill marine organisms, but when it reaches the surface of the water, some chemicals evaporate, become part of the atmosphere, and pollute the air.

Answer:
Option D, the "biological ladder"
Explanation:
The food chain is the network of organism in which all are dependent on each other for their food, energy source and survival.
The circle of life depicts the time frame starting from origin of a life form till its death and the intermediate stages.
The tree of life basically determines which organism has evolved from which other organisms.
The biological ladder represents the development of species from simple form to a much complex form.
