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

Answers

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.

How is climate change like a game of Tetris? How can kids stop climate change? What are some of the ways that you will help?

Answers

Answer:

Climate change is like a game of Tetris because a lot of little things add up to it. you don't fill up the screen in Tetris in one move, small things build up over time.

Kids can stop climate change by being environmentally conscious and making an effort to reduce the size of their carbon footprints. They can choose to take public transportation instead of driving to school, they can take colder or shorter showers, and they can reduce their waste by using reusable bags at the grocery store or reusable cups instead of throw aways.

Some of the ways that i will help is by bringing my own reusable cup next time i get a soda at the gas station and taking shorter showers.

Friend me!!!!

Explanation:Loess is made of silt that were wind blown from vertical cliffs.

Sand dunes are basically hills of sand. They form when wind is impeded by a rock and it drops some of the sand as it hits the rock. Slowly the deposited sand builds up to form bigger dunes.

Hills since sand dunes are hills also, this is also considered a formation made by wind deposition.

Explanation:

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.

Answers

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.

A. 0%
B. 25%
C. 50%
D. 75%

Answers

A would be a good answer

A genetic cross between two F1-hybrid pea plants for spherical seeds will yield 50% of plants with a heterozygous genotype in the F2 generation. Thus, the correct option for this question is C.

What is a Genotype?

A genotype may be defined as the ultimate combination of alleles of those genes that are subsequently selected for specific study in order to reveal some genetic facts and traits of an individual.

According to the question, the two F1-hybrid pea plants for spherical seeds have the genotype of Rr and when these two genotypes are crossed with one another, it produces offspring with the genotypes RR, Rr, Rr, and rr. In this set of offspring, 2 of them have heterozygous genotypes.

Therefore, a genetic cross between two F1-hybrid pea plants for spherical seeds will yield 50% of plants with a heterozygous genotype in the F2 generation. Thus, the correct option for this question is C.

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?

Answers

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.
