Chromosomes are composed of deoxyribonucleic acid (DNA) mole

There are mainly two molecules that function as genetic material in living organisms.

These are ribonucleic acid(RNA) and deoxyribonucleic acid(DNA).

The organisms having DNA as genetic material require packaging of DNA as it is a long polymer of deoxyribonucleotides.

In the case of human beings, the length of DNA in a cell is approximately 2.2 meters which is very large as compared to the size of the nucleus( approximately 10^-6 meters).

So, the DNA has to be made compact for it to be present inside the nucleus of a cell.

Therefore, the DNA present inside the nucleus of a cell undergoes coiling and compaction through several stages before finally becoming a chromosome, which is shown in the adjoining diagram.

Thus, chromosomes are composed of deoxyribonucleic acid (DNA) molecules.

<span>At the end of meiosis II, compared to the DNA from the original cell, the DNA in each of the four new cells is C)half as much and genetically different from the original. Meiosis is the type of cell division in which the genetic material is reduced by half. Thus, choices B and D are incorrect. Further, the exchange of genetic material between homologous chromosomes so-called the crossover occurs during meiosis, so DNA in new cells will be genetically different from the original DNA. Thus, the correct choice is C.</span>

Name two medical technologies that have helped combat the spread of disease in cities. Explain how each technology has helped.
JulijaS [17]

Answer:

contact tracing and global surveilliance

Global surveillance of emerging infectious diseases aims to rapidly detect changes in the incidence rate of endemic diseases and in promptly recognizing and characterizing syndromes caused by previously unknown pathogens of epidemic potential.

Contact tracing has provided a way for local and state officials to prevent the spread of disease before it can affect the majority of the citizens in an area.

hope this helps, plz vote me the brainliest :)) thnks

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.
