What is earthquake and its causes?An earthquake is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves.
Earthquakes are the result of sudden movement along faults within the Earth. The movement releases stored-up 'elastic strain' energy in the form of seismic waves, which propagate through the Earth and cause the ground surface to shake.
Over 80 per cent of large earthquakes occur around the edges of the Pacific Ocean, an area known as the 'Ring of Fire'; this where the Pacific plate is being subducted beneath the surrounding plates.

If a man has red-green color blindness, a sex-linked dominant trait, what is a possible genotype of his father? I. XR Y II. Xr Y III. XR XR IV XR Xr A. Only III B. I and III C. I and II D. I, III, and IV
Answer:
C
Explanation:
The possible genotype of his father is [tex]X^RY[/tex] and [tex]X^rY[/tex].
For sex-linked traits, an affected man always inherit the affected allele from the mother. The other chromosome, which is the Y chromosome is always from the father and this confers maleness on individuals.
The father of a man affected for a sex-linked trait can be affected for the same trait or otherwise. It does not have any bearing on the male child since the father only donates the Y chromosome to the male child.
Hence, in this case, the father can either be affected for the same trait ([tex]X^RY[/tex]) or be free from it ([tex]X^rY[/tex]).
The correct option is C.

All materials within ecosystems can be recycled.
Answer:
All the things expect enegry are recycled.
Explanation:
When the decomposer decomposes the organic substances than they are taken by plants in the form of nutrition and minerals. Likewise, the food prepared by the plants are taken by animals and the nutrition is recycled. The oxygen and carbon dioxide cycle is also recycled. When the animals releases carbon then the plants take it and gives out the oxygen. In this way oxygen and carbon dioxide cycle is also maintained in nature.But incase of enegry it cannot be recycled but frequently transfered from one form to another form.

If snow be white, why then her breasts are dun;
If hairs be wires, black wires grow on her head.
I have seen roses damask'd, red and white,
But no such roses seel in her cheeks;
And in some perfumes is there more delight
Than in the breath that from my mistress reeks.
I love to hear her speak, yet well I know
That music hath a far more pleasing sound:
I grant I never saw a goddess go,

And yet by heaven, I think my love as rare,
As any she belied with false compare.

which words in the sonnet indicate that the tone is satirical ?
Answer:
"black wires"
"reeks".
Explanation:
William Shakespeare's "Sonnet 130" is a satire or mocking critique of the conventional sonnets that writers write. In this sonnet, he talks of a young lady who is short of conventional beauty ideals.
In the given lines from the sonnet, the poet/ speaker talks of his mistress whose "eyes are nothing like the sun" and he keeps on describing her features as opposed to one praising his lover. Rather, the speaker in this sonnet uses the negative descriptions in describing his mistress, like calling her hair "black wires" and her breath "reeks", far from the delightful perfumes that a lady is supposed to exude.
Thus, the two words that have a satirical tone in the sonnet are "black wires" and "reeks".

synthesis.
RNA polymerase
DNA strand
Answer:
its transcription
Explanation:
The process shown in the diagram is called transcription.
Transcription represents the first stage of protein synthesis. During this process, genetic information on DNA templates are transcribed to genetic codes in the form of messenger RNA.
The transcription process starts with the binding of the RNA polymerase enzyme to the promoter region of a gene. This causes the unwinding of the double helix structure of DNA in the binding region. Thereafter, the RNA polymerase starts synthesizing the complementary bases of the DNA template.

Consider aerobic cellular metabolism from the beginning to end. What is the sequential order of the metabolic processes that starts with glucose and results in the production of carbon dioxide, water, and ATP?
Explanation:
This starts with substrate level phosphorylation(glycolysis) in the cytosol of cytoplasms.Two ATPs are needed for phosphorylation of glucose.With eventual formation of 4 ATPs with 2NET GAIN ATPs,NADH+,and Pyruvate.
The Pyruvate reacts with co-enzyme A to form Acetyl coA-This is the bridge reaction or link reaction.
The Acetyl Co-A diffuses into the mitochondria where it combines with oxaloacetate to form citrate,the latter form Alpha ketoglutaric succinic,fumate,malate and back to oxaloacetate.The cycle of events is called the Kreb's Cycle.
Net of 2ATPs are formed,co-enzymes NADH+ and FADH2 ,water molecules,and Co2 are produced.These takes place in the mitochondria.
Then the NADH+ and FADH2 takes the hydrogen ions into the inner mitochondria where Hydrogen is split into electron and Protons.This forms the beginning of oxidative phosphorylation.
The electrons are transmitted by the carrier proteins to form the electron transport chains,which provide the PMF. The latter pumps the protons across the walls of mitochondria into the intramembrane space.
The high concentration of the protons produce the elecrochemical gradients which make the protons to diffuse back into the matrix. it is the changes in the elctrochemical gradients that supply the energy needed by ATPase enzymes for synthesis of ATPs. A total of 28ATPs are produced in oxidative phosphorylation.
Answer:
The total ATPs produced in the sequence of glycolysis pyruvatre,Co-enzyme A, kreb's Cycle and oxidative phosphorylation are 32ATPs per molecule of glucose splits in Glycolysis.

Functions of: [A] nucleolus [B] plasma membrane.
Answer:
The nucleolus is considered as the brain of the nucleus. It occupies around 25% of the volume of the nucleus. It is mainly involved in the production of subunits which then together form ribosomes. Therefore, nucleolus plays an important role in protein synthesis and the production of ribosomes in eukaryotic cells.
The primary function of the plasma membrane is to protect the cell from its surroundings. Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells.

Which viral replication cycle is represented in part A of this diagram?
O A. Dormant cycle
OB. Replication cycle
C. Lysogenic cycle
O D. Lytic cycle
Answer:
The correct answer is - option D. lytic cycle.
Explanation:
The lytic cycle is one of the two viral reproduction cycle. Generally, it is the major reproduction cycle. In this cycle reproduction of the viruses takes place inside the host cell and produce more viruses. In the production of the more viruses the host cell and it''s destruction takes place in the end. The 5 steps that takes place are as follows:
1- attachment - viruses attach to the cell.
2-penetration- only nucleic acid or genetic material is injected into the host cell through the hole made by the tail fibers and enzymes.
3- synthesis - replication of viral nucleic acid and protein and envelope.
4- assembly - assembling of the new viruses formed.
5- release.
Thus, the correct answer is - option D.

Crop rotation is a method of soil conservation because _______. a. the land produces more than one type of crop b. it requires plowing and tilling that reduces soil compaction c. it does not use the same parcel of land in sequential seasons d. it avoids the depletion of soil nutrients
Answer:
d. It avoids the depletion of soil nutrients.
Explanation:
Crop rotation is the process of planting different crops in the same area of land in rotation. This allows the breathing of the soil as well as the retention of nutrients in the soil.
Crop rotation is one form of conserving soil as it helps in saving the nutrients of the soil from getting depleted. As different crops require different nutrients, the change in crop plantation between different types of crops help in maintaining the fertility of the land. This way, when crops are planted in rotation, there is also the rotation of the different nutrients required for the different crops planted, thus allowing the cycle of nutrient change to take place.
Thus, the correct answer is option d.

Cell division is preceded by two growth phases. Besides growth, both G1 and G2
Answer:
A
Explanation:
a. contain checkpoints that determine if the cycle will continue.
b. help move chromosomes to the new daughter cells.
c. produce more chromosomes before the cell divides.
d. grow and produce enough cytoplasm to fill two cells.
The correct answer would be that G1 and G2 contain checkpoints that determine if the cycle will continue or otherwise.
The cell cycle generally has three checkpoints that happen at G1, G2, and M phase of the cycle.
At G1 checkpoint, the integrity of the DNA of the cell is assessed to ensure that there are no damages and other conditions such as size and energy reserve are checked.
At G2 checkpoint, the cell is assessed for proper chromosome duplication to ensure that there are no mistakes or damages. The size of the cell and the amount of protein are also checked to ensure that the cell is ready for the active division phase.
At M checkpoint, correct attachment of the spindle fiber to the kinetochore of the chromosomes is checked. This checkpoint is also known as the spindle checkpoint and it happens towards the concluding phase of the metaphase stage.
The correct option is therefore, A.
