If energy is traveling from the plant → Goat → Jackal → Lion, what percentage of the energy from the plant will make it up to the lion? How do you know?

Answers

Answer:

Because the goat ate the plant which the energy from the plant transfers from the plant to the goat to the jackal to the lion

The producer receives its energy from the sun, which is the ultimate source of energy. Meaning all the energy we use comes from the sun. Like I said earlier, the energy from the corn moves into the mouse. Not all the energy that the corn has is able to be transferred into the mouse, only about 10% of the available energy is transferred to each trophic level. A trophic level is the position an animal occupies in a food chain. And again only about 10% of energy is transferred from the mouse to the owl.

To find 10%, we can multiply the starting number by 10%. We need to change 10% into decimal form, with is 0.10. Say the corn has 2,000 joules of energy. We will multiply 2,000 x 0.10 = 200

A short cut is to move the decimal over one spot to the left. 2,000.0 to 200.00 or 5,500.0 to 550.00

The carrot has 8,800 Kcal of energy. The rabbit would have 880 Kcal of energy, the fox would get 10% of that, which is 88 Kcal of energy and the lion gets 10% of that, 8.8 Kcal of energy.

This information can also be shown in the form of an energy pyramid. The bottom of the pyramid is always the producer. The next layer of the energy pyramid is the primary consumer, the next level is the secondary consumer, then the tertiary consumer. As we go up the pyramid, the energy decreases. Along with the energy decreasing there is also a decrease in the number of animals available at each level. For example there are more producers than primary consumers, more primary consumers than secondary consumers, and more secondary consumers than tertiary consumers.

DNA polymerase has multiple mechanisms for editing and error correction whereas the capacity for error correction in RNA polymerases seems to be quite limited. However, like DNA mutation, an RNA polymerase error in transcription can cause production of a mutated protein. The limited error correction of RNA polymerase seems to be inconsistent with the potential serious consequence of producing a protein with an altered amino acid sequence. Select three reasons that explain why error correction is not as necessary in RNA polymerases as it is in DNA polymerases.

Answers

The given question is incomplete as the option are not provided however, the correct options are as follows:

Defective proteins are often degraded quickly, making their effects temporary.

Single amino acid substitutions caused by errors in mRNA transcription would not affect protein function.

Unlike DNA mutations, mRNA transcripts have short half-lives and are not inherited across many generations.

Degradation of defective proteins activates mRNA repair pathways RNA polymerases synthesize many transcripts per gene, so only a small fraction of RNA transcripts would have errors.

ch mRNA molecule is only translated once and then degraded

Answer:

The correct answer is - statements 1, 3, and 4.

Explanation:

DNA polymerase is the enzyme that is responsible for the production of the new DNA molecule and any mutation in this enzyme that will inhibit the DNA repair process which affects future generations.

RNA polymerase is an enzyme that is responsible for the transcription of DNA to mRNA and any error-prone mRNAs have chances of degradation. Error in DNA replication is from generation to generation as it is inherited

The process of transcription is quick.

Which of the following would cause an error in DNA replication?

A. DNA ligase connecting chunks of DNA
B. DNA polymerase paring C with G
C. The original DNA strands never being separated
D. DNA Polymerase checking the DNA

Answers

The correct answer is A
The correct answer here would be C. DNA replication is usually semiconservative: Each of the original strand serves as a template for a complementary daughter strand. The processes that occur in DNA replication couldn’t even get started if the strands are never separated.

The other answer choices are true in themselves, and none of them would independently be a cause for error in DNA replication.

A break in Earth’s lithosphere?

Answers

Answer:

A fault is a fracture, or break, in Earth's lithosphere, along which blocks of rock move past each other.

I hope it's helpful!

Earthquakes are the brittle breaking of the lithosphere. There is no sharp boundary between the lithosphere and asthenosphere. The Earth gets gradually hotter as you go deeper, so the viscosity of rocks gradually gets smaller. On the other hand, the crust and mantle are different rock types.

The gene for a long neck also gives stronger, faster muscles, which gives tortoises with this trait
an advantage in catching insects. How would this advantage affect the population of tortoises from
Generation 1? How may that affect subsequent generations?

Answers

Answer:

it would help them thrive

Explanation:

because it anables them to catch more with there stronger faster necks

The shift in the traits of tortoises in the population states how natural selection drove the evolution of the tortoises.

Why do tortoises shift in their traits?

During the evolution, with an extended period of time, the shorter vegetation became less available and tortoises with short necks had the disadvantage to survive in that area.

Tortoise develops genes for a long neck and having stronger, faster muscles, which gives tortoises with this trait an advantage in catching insects.

This natural selection helps the tortoises, to survive by catching more food in a particular area, it states tortoises with long necks are the only tortoises living during evolution.

Therefore, this advantage increases the survival rate of the tortoise population.

In a normal cellular protein, where would you expect to find a hydrophobic amino acid like valine?
A.In the interior of the folded protein, away from water.

B.On the exterior surface of the protein, interacting with water.

C.In the transmembrane portion interacting with lipid fatty acid chains.

D.In the interior of the folded protein, away from water, or in a transmembrane portion interacting with lipid fatty acid chains.
E. Anywhere in the protein, with equal probability.

Answers

Answer:

D. In the interior of the folded protein, away from water, or in a transmembrane portion interacting with lipid fatty acid chains.

In a normal protein, it is expected to find valine in the interior of the folded protein, away from water, or in a transmembrane portion, interacting with lipid fatty acid chains (Option D).  

Aminoacids can contain hydrophilic side chains that interact with water molecules or hydrophobic side chains that cannot make hydrogen bonds and therefore do not interact with water.

In membrane protein, hydrophilic amino acids are arranged so they can interact with water on the surface of the cell membrane,

Moreover, hydrophobic amino acids of membrane proteins are arranged away from water so they can interact with fatty acid chains in the transmembrane portion of transmembrane proteins or with other hydrophobic amino acids in the interior of the folded protein.

In conclusion, in a normal protein, it is expected to find valine in the interior of the folded protein, away from water, or in a transmembrane portion, interacting with lipid fatty acid chains (Option D).

Cellular Respiration and Fermentation

Answers

Answer:

The stages of cellular respiration are: Glycolysis, pyruvate oxidation, Krebs cycle and phosphorylative oxidation.

The fermentation stages are: glycolysis and pyruvate regeneration.

Explanation:

Cellular respiration is a biochemical process that occurs in all aerobic organisms and aims to promote the obtaining of the necessary energy so that the cells can perform the activities they need to perform. Cellular respiration occurs in mitochondria and oxygen must be present in the process.

Fermentation is the biochemical process that replaces cellular respiration in organisms that do not survive in the presence of oxygen, the anaerobic organisms that are some fungi and bacteria. Fermentation also aims to produce cellular energy.
