The lungfish Protopterus aethiopicus has a genome 38 times larger than that of humans. Most of the DNA in this species is noncod

ing repetitive DNA. How could you create a library of clones that would let you compare just the genes in the lungfish to the genes in humans?

Answer:

1.Carbon dioxide is converted to sugar used for food. - 1. Location- A

2.Carbon trapped in fossil fuels is converted to carbon dioxide. - 2. Location- C

3.Organic carbon is converted to fossil fuels. -3. Location- E

4.Carbon dioxide is converted to carbonates.- 4. Location- D

5.Sugar is broken down and converted to carbon dioxide. - 5. Location- F

Explanation

1. Carbon dioxide is converted to sugar used for food: The carbon dioxide is converted into sugars by the process of photosynthesis, which occurs in the green plants. Plants trap carbon dioxide and sunlight from the atmosphere, to synthesize their food.

2. Carbon trapped in fossil fuels is converted to carbon dioxide: The fossil fuel produced deep inside the earth, acquired by the factory. From the factory the carbon dioxide liberated to the atmosphere.

3. Organic carbon is converted to fossil fuels: The organic carbon obtained after the degradation of organic matter is responsible for the synthesis of fossil fuels.

4. Carbon dioxide is converted to carbonates: The carbon dioxide from the atmosphere gets dissolved with water of the water body and termed as carbonic water.

5.Sugar is broken down and converted to carbon dioxide: The glucose or sugar as a source of food in plants gets broken down into carbon dioxide and water by the process of respiration.

Answer:

Introduction In ecology and biology, abiotic components are non-living chemical and physical factors in the environment which affect ecosystems. Biotic describes a living component of an ecosystem; for example organisms, such as plants and animals. Examples Water, light, wind, soil, humidity, minerals, gases.

Having freckles (F) is dominant over not having freckles (f). A parent with freckles is crossed with a parent without freckles.

Step2247 [10]

Answer:

This is a trick question, and only because the question is vague

Explanation:

Use a Punnet Square to figure out the percentages.

If the parent with freckles (let's just call them Parent A) is homozygous dominant, their genotype would be FF. The parent without freckles (Parent B) has a genotype of ff.

In any situation, the probability of these two having a child that is homozygous dominant for freckles is 0%. (see punnet squares for more info).

Now here's where it gets a little more confusing because the question is kind of vague on this.

Assuming that Parent A is homozygous dominant (both genes for this are dominant (FF)), then the probability of having a heterozygous (non-identical genotype letters, meaning they carry the recessive trait) genotype is 100%. However, if Parent A is also heterozygous, then that percentage decreases to 50%

For Situation A (Parent A is homozygous dominant), the probability of a homozygous recessive genotype is 0%

For Situation B (Parent A is heterozygous dominant), the probability of a homozygous recessive child is 50%.

Please see the Punnet square I made for more information.

Key:

- Homozygous Dominant: FF

- Heterozygous Dominant: Ff

- Homozygous Recessive: ff

(heterozygous recessive does not exist, because that would mean one of the genes is dominant, which would overpower the recessive gene)

I really hope this helps, and if you're confused by this, please do not hesitate to let me know!
