Answer:

Please find the summary of what happens during DNA replication below

Explanation:

DNA replication is the process by which a DNA molecule is duplicated into two identical copies. It occurs in the nucleus of the cell prior to any cellular division. The process includes:

- The double stranded DNA is first unwound by an enzyme called DNA HELICASE into a replication fork consisting of two single strands of DNA.

- Another enzyme called DNA POLYMERASE binds to the DNA and begins to add NUCLEOTIDES to each strand using complementary base pairing rule i.e. A-T, G-C. To do this, short sequences of RNA called PRIMER are synthesized by an enzyme called PRIMASE, which serves as building block for DNA polymerase to act.

- However, DNA POLYMERASE can only work in the 5'-3' direction i.e. on the leading strand which runs from 3'-5' direction. Short pieces of DNA called OKAZAKI fragments are synthesized on the lagging strand, which runs from 5'-3' direction.

- An enzyme called LIGASE joins the okazaki fragments together into a whole DNA on the lagging strand.

After the replication process which follows the SEMI-CONSERVATIVE MODEL of replication, each DNA molecule will contain one old strand called PARENT STRAND and one NEW strand.

prisoha [69]

Answer:

Option D

Explanation:

When amniotic sac breaks and its internal fluid spilled then there are high chances that the fluid may enter into the throat of the infant and may block his/her air passage way. Therefore, in such situation a standard solution is formulated which requires the doctors to suction the air passageway of infant and restrict it from getting choked and contaminated with meconium. A valve mask is primarily used before suctioning  

Hence, option D is correct

jasenka [17]

Answer:

O sal tem uma grande capacidade de absorver água do ambiente.

Explanation:

A passagem de oxigênio pelas guelras de um peixe é um exemplo de difusão porque a difusão ocorre quando a concentração de uma substância é maior em uma região e menor em outra região, de modo que as partículas se movem da região superior para a região inferior. A glicose entra na célula por meio do processo de transporte passivo facilitado porque passa por uma membrana semipermeável por uma proteína específica. O transporte iônico nas células nervosas é o exemplo do transporte ativo porque se move pelo uso da energia contra o gradiente.

O sal tem uma forte capacidade de absorver água do seu entorno, então quando a alface temperada com sal, o sal absorve a água presente no interior da alface, portanto a retirada da água é a retirada da água é a causa do murchamento.

Earning Task 1 rections: Observe a landscape garden in your nearby area. In three to five sentences, give your ideas based on yo
9966 [12]

Answer:

When designing a residential landscape, the most important step is to put a plan on paper. Developing a master plan will save you time and money and is more likely to result in a successful design. A master plan is developed through the 'design process': a step-by-step method that considers the environmental conditions, your desires, and the elements and principles of design. The goal is to organize the natural and man-made features in your yard into an aesthetic, functional, and environmentally sustainable landscape.

THE DESIGN PROCESS

The five steps of the design process include: 1) conducting a site inventory and analysis, 2) determining your needs, 3) creating functional diagrams, 4) developing conceptual design plans, and 5) drawing a final design plan. The first three steps establish the aesthetic, functional, and horticultural requirements for the design. The last two steps then apply those requirements to the creation of the final landscape plan.

The process begins with a site inventory and analysis of soil, drainage, climate conditions, and existing vegetation. This is a critical step for both plant selection and placement and locating family activities and functions. It's important because the same climate conditions that affect the plants—temperature, humidity, rain, wind, and sunlight—also affect you, the user. The next step is to make a list of your needs and desires—this helps you determine how your yard and landscape will be used. The site and user analyses will also help you establish a theme for the form and style of your design. The functional diagram is then used to locate the activity spaces on the site and from this diagram a conceptual plan is developed. The last step is a final design that includes all the hardscape and planting details that are necessary for installation. Throughout the design process there are ten important things to consider:

Understand your site for plant selection and activity location

Remember the user by considering what you want and need

Use a form and/or style theme to help determine shapes and organize spaces

Create and link spaces by designating activity areas and linking with elements

Consider the function of plants for both the environment and the user

Structure the plantings by using massing and layering techniques

Highlight important points such as transition areas and focal points

Pay attention to detail in the materials, the colors, and the surface textures

Take time into account for the growth and maintenance of plants

Protect your resources by using sustainable design practices

UNDERSTAND YOUR SITE

A thorough inventory and analysis of the site is important to determine the environmental conditions for plant growth and the best use of the site. Issues of concern include the soil type, topography, and regional climate. The type of soil determines the nutrients and moisture available to the plants. It is always best to use plants that will thrive in the existing soil. Although soil can be amended, amendment is often costly and most times ineffective. Existing vegetation can provide clues to the soil type. Where plants grow well, note the soil conditions and use plants with similar growing requirements. Pay particular attention to areas where plants are not doing well and adjust when choosing new plants. Topography and drainage should also be noted and all drainage problems corrected in the proposed design. A good design will move water away from the house and re-route it to other areas of the yard.

Climate concerns begin with temperature: plants must be able to survive the average high and, most importantly, the average low temperatures for the region. Use the USDA Plant Hardiness Zone Map (www.usna.usda.gov/Hardzone/) as a starting point to choose plants appropriate for your zone, but remember microclimates within your yard can offer alternatives. Sun/shade patterns, the amount and length of exposure to sun or shade (Figure 1), create microclimates (sometimes called microhabitats). Recording site conditions and existing vegetation on a base map will reveal the location of microclimates in the yard. Plants usually fall into one or two of four microclimate categories-full sun, partial shade, shade, and deep shade. It is important to remember that sun/shade patterns change with the seasons and over time as trees get larger.
