Mendel chose the pea, one of many species, to study because the plants and seeds exhibit a variety of distinctive characteristics that appear in two readily recognizable forms (e.g., seed shape is round or wrinkled; plant height is tall or short).

George Mendel, the father of genetics, chose pea plants for his genetic experiments for a variety of reasons, including

• Garden plants are simple to grow.

• Pea plant blooms are hermaphrodites, which means they exhibit traits of both sexes.

• Plants of the pure breed can be easily obtained through self-fertilization.

• Pea plants produce more quickly than other plants.

• They have a high rate of survival and remarkable disease resistance.

Gregor Mendel's research on pea plants led him to the fundamental ideas of inheritance. He came to the idea that genes are passed down from each parent as unique, paired units.

Mendel observed how parental genes separated and if they showed up as dominant or recessive qualities in the offspring. Gregor Mendel experimented with hybridization on about 29,000 pea plants. Mendel found that peas were the perfect subject since they possessed seven easily observable features that he could control. He set up two settings before starting his pea studies.

As a result, we can infer that Mendel chose the pea as the species to study out of all the others since it has a diversity of distinguishing traits in both its plants and seeds.

The population is not in hardy weinberg equilibrium, because it does not match the previous generation.

The frequency of individuals = individuals/total population

The frequency of Green individuals = 1092/1200

The frequency of Green individuals = 0.91

                                                       q² = 0.91

                                                    √ q² = √0.91

                                                         q = 0.953

By using the first Hardy-Weinberg equation:

                                                                p + q   = 1

                                                                p + 0.953 = 1

                                                                p   = 1 - 0.953

Varicella Zoster is an infectious viral disease causing chickenpox in children and shingles in grown-ups. Inoculation plays a crucial part in avoidance and lessening complications.

Women and noblemen,

Nowadays, I would like to examine a vital and predominant viral disease known as Varicella Zoster. Varicella Zoster, commonly alluded to as chickenpox, is caused by a varicella-zoster infection. It fundamentally influences children, but can too affect grown-ups who have not been already contaminated.

Varicella Zoster presents as a profoundly infectious sickness characterized by a particular hasty, fever, and common disquietude. The infection spreads through coordinated contact or respiratory beads, making it effortlessly transmissible inside families and communities.

Whereas chickenpox is for the most part a gentle ailment in children, it can lead to more serious complications in grown-ups, pregnant ladies, and people with debilitated resistant frameworks. These complications incorporate pneumonia, bacterial contaminations, and in uncommon cases, neurological complications such as encephalitis.

Luckily, the improvement of a profoundly successful antibody has essentially diminished the frequency of Varicella Zoster around the world. Immunization not as it were secures people from the distress and potential complications of chickenpox, but too makes a difference anticipate the infection from spreading inside the community.

In any case, Varicella Zoster doesn't halt at chickenpox. Once the introductory contamination settles, the infection remains torpid inside the body and can reactivate a long time afterward, causing a condition known as herpes zoster, or more commonly, shingles.

Shingles are characterized by a difficult hasty that ordinarily happens in a single dermatome, regularly along the middle or confront. The reactivated infection can cause critical pain and inconvenience, enduring for weeks or indeed months. Moreover, complications such as postherpetic neuralgia, a persistent torment disorder, can happen, especially in more seasoned people.

To combat the chance of shingles, an isolated antibody called the shingles antibody or herpes zoster immunization has been created. This antibody not as it were makes a difference anticipate shingles but moreover diminishes the chance of postherpetic neuralgia.

In conclusion, Varicella Zoster, enveloping both chickenpox and shingles, could be a viral contamination that has critical suggestions for open well-being. We have made significant progress in reducing the burden of this disease through extensive vaccination efforts.

In any case, ongoing efforts to prevent Varicella zoster from returning to our communities and to protect powerless populations require prompt attention and vaccination.

Much obliged to you for your thought. Let's collaborate to ensure a better future for everyone.

Primary succession and secondary succession are two different processes of ecological succession that occur after a disturbance in an ecosystem.

Primary succession is the process by which a new ecosystem is formed on barren land where no soil or organisms exist, such as after a volcanic eruption or glacial retreat.

The process begins with the colonization of bare rock or sand by pioneer species like lichens and mosses. Over time, these organisms break down the rock or sand, creating soil that can support the growth of larger plants like grasses and shrubs. Eventually, trees and other complex organisms take root, creating a mature ecosystem.

Secondary succession, on the other hand, occurs when a disturbance, such as a wildfire or human activity, destroys an existing ecosystem but leaves behind soil and some organisms.

The process begins with the growth of pioneer species that can quickly colonize the area, such as weeds and grasses. As the ecosystem recovers, more complex organisms move in, and the ecosystem slowly returns to its previous state.

In summary, primary succession occurs on bare land without soil or organisms, while secondary succession occurs on land that has been disturbed but still contains some soil and organisms. The processes of succession are essential for the renewal and recovery of ecosystems after a disturbance.

We breathe through nasal cavities, amphibians through the skin, the nasal mucosa of amphibians is less specific than the human one, amphibians' lungs are primitive, they need a specific pH for breathing.

Amphibians have a primitive lung in the adult stage that is not efficient enough to be the animal's only form of respiration, which is supplied by cutaneous respiration. Thus, adult amphibians have lung breathing and skin breathing.

Amphibians have three structures for breathing: the lungs, the mucous membranes of the pharynx and mouth, and the skin. The lungs are made up of two pouches with no internal division. When still in the larval stage, they breathe through gills.

Pulmonary breathing occurs in all terrestrial vertebrates. In amphibians, it can be seen that, in addition to pulmonary respiration, these organisms need gas exchange performed on the surface of their body (cutaneous respiration).
