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.

"My mistress"

Read Shakespeare's "Sonnet 130."
My mistress' eyes are nothing like the sun;
Coral is far more red, than her lips red:
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,
My mistress, when she walks, treads on the ground:
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 ?

Answers

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".

Answer: “black wires” and “reeks”

Cell division is preceded by two growth phases. Besides growth, both G1 and G2

Answers

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.

Why does the troposphere contain the most water vapor out of the atmosphere? Everywhere says that it does but why?

Answers

Answer:

The troposphere does contain the most water vapor out of the atmosphere

Explanation:

The troposphere does contain the most water vapor out of the atmosphere because the troposphere is where all the weather conditions like: rain cloudy, hurricanes take place and all the weather conditions have water vapor because most of the weather conditions have clouds, or water vapor.

Because plants release water during the transpiration process, the troposphere contains the most water vapour in the atmosphere. This remains here, and as a result rain forms.

   

What is the atmosphere?

   

The atmosphere is the earth's outer layer, which is further subdivided into troposphere, stratosphere, mesosphere, and so on. The troposphere is the part of the atmosphere closest to the earth, and it is where rain and clouds form.

The upper stratosphere is less disturbed and more stable than the troposphere, as less wind disturbance is seen here. In this layer, planes and jets are travelling. It has a special layer called the "ozone layer" that protects the earth from the UV light of the sun. The mesosphere is the coolest of these atmosphere layers.

The troposphere has disturbances such as those caused by winds; clouds form here. There are various gases, such as oxygen, carbon dioxide, nitrogen, water vapor, and so on. The water vapour is the result of transpiration from plants and evaporation from water bodies.

Hence, this troposphere layer contains water, because the water above it cannot remain liquid due to the increased temperature of the stratosphere.

7. List all the possible different gametes that could be produced from the following parents:
a. Tt
b. GG
с. ff

Answers

Answer:

a. Tt - Gametes T and t

b. GG - Gametes G only

с. ff - Gametes f only

Explanation:

Gamete formation or meiosis is a cellular division of the reproductive cells in sexually reproducing organisms. Meiosis produces daughter cells (gametes) with a reduced number of chromosomes (by half) as the parent cell.

According to Gregor Mendel in his law of Segregation, he stated that the alleles of a gene get separated into gametes in such a way that only one allele can be found in the gamete. The separation is random and equal.

Based on this, a heterozygous parent Tt will produce gametes with alleles T and t in an equal proportion. Since parents GG and ff contains the same alleles in their genotype, they will produce gametes with only one type of allele each i.e. Gametes with alleles G and f respectively.

HEY UJALA CAN U PLEASE HELP ME IN THIS QUESTION HOW HORMONES ARE INVOLVED IN OSMOREGULATION OF KIDNEYS

Answers

Answer:

Hormones are involved in the osmoregulation of kidneys by regulating the levels of water.

Such as if the water level is excess in the body fluids, the hormone will help the kidneys to filter as much water as they can from the glomerular capillaries. So, As a result dilute urine is formed.

Now, If the water level is very low in the body fluids, the hormone will help the kidneys to absorb most water and filter less water from the glomerular capillaries. As a result the urine formed is concentrated.

In Chapter 3, "Coordination and Control" You will come to know that the hormone is ADH (Anti-diuretic hormone) called vasopressin.

Answer:

Kidney plays a very important role in Osmoregulation by regulating the amount of water reabsorbed.Anti Diuretic harmone produced by pituitary gland plays a key role.Kidney regulate osmotic pressure of a mammals blood through extensive filtration and purification in a process known as osmoregulation.

The loop of Henle establishes a salt gradient in the medulla, anti diuretic harmine regulates the level of water reabsorption in the collecting duct.

Harmones like ADH helps in reabsorption of water.

This is because they are more productive and perform better because they have expertise range of experienceand working methods that can boost problem-solving capacity and lead to greater productivity. They tend to have more integration and communication than homogeneous group because they bring broader ideas and new perspectives to the table and many members will be partaker of the community.

Answers

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.
