What is the average for the following set of measurements?
lisabon 2012 [21]
20C

The average is getting the total number of data points and diving by the number of how many data points were added together.

Average is similar to mean. Mean in statistics is the level where all the data points fall into or just simply the average point.

2/5

Cells group together to create tissue

3/5

Tissues group together to make organs

4/5

Organs group together to make organs system (A human does not have an organ system if say the stomach or heart is taken out(Because it kills them))

One of the drugs that have emerged in the last few years to help reduce cravings in opioid addicts is
joja [24]
Patients will use medications to re-establish traditional brain functions and reduce cravings. Medicines are accessible to the patients for treatment of opioid, tobacco, and white plague.

One of the drugs that have emerged in the last few years to help reduce cravings in opioid addicts is Methadone.

There are some other drugs available to treat such addicts. For example, buprenorphine, and naltrexone are also used to treat opioid addiction.
<span>Methadone and buprenorphine controls the withdrawal symptoms and provides relief to patients facing cravings. </span>

What are the real world applications of biology? And why is it important to us?
Papessa [141]

Foods and Beverages

People consume biological products both to survive and for enjoyment. Livestock provide food for humans, and those animals in turn need their own food to survive. Plants provide endless options for food: feed for animals, fruits, vegetables, oils for eating or cooking and flavoring extracts. Beets and sugarcane can be made into sugar for sweetening. Honeybees use flower nectar and make honey. Sugar maple trees’ sap can be boiled to make maple syrup. Coffee comes from coffee tree seeds, whereas tea originates from tea plant leaves.

Microbes and enzymes enable the creation of foods such as cheese, yogurt and bread. Barley, yeast and hops work together to make beer, with enzymes activated with the malting of barley and the yeast metabolizing in fermentation. Wine is made in similar fashion from grapes and other fruits.

Other biological processes aid in food production. Compost made from decaying plant and animal waste serves as a natural fertilizer for organic crops. Whether insect or bird, pollinators continue the process of plant life, giving humans and other animals food and beverages to eat and drink.

Clothing and Textiles

People wear clothing made from biological substances. Cotton provides material for many clothing items. Linen, made from flax, is another plant-based fabric. Even polyester is made from biomass in the form of fossil fuels. Plants provide the basis for fabric dyes and nylon. Carpets, upholstery, curtains, towels and countless other household textiles are made from plants.

Care

Biological sources make up the ingredients for many personal care and beauty products. Shampoo, henna dye, lotion, cosmetics, perfumes, diapers, loofahs, nail polish remover and soap represent only a few examples of biology-based everyday items.

Transportation and Leisure

Tires are made from the rubber of the rubber tree. Wood serves as the source for sports equipment such as baseball and cricket bats, bowling pins and lanes. People often play sports on living grass turf. Musical instruments such as clarinets, violins, drumsticks, drums and pianos contain biologically sourced components. Many boats are still made of wood, as are docks. Boaters still use plant-based ropes.

Buildings

Many homes around the world are built from plants. Wood from trees provides framework for houses and other buildings and the furniture within them. Rugs and other floor covers are made from wood, cork, fibers and linoleum, all plant-based. Paper from wood, erasers from rubber, inks, pens and pencils all derive from plants.

Fuels

Many fuels used today originated from a biological origin. Fossil fuels such as petroleum and natural gas formed from decayed plant and animal matter. Modern biofuels are made from plant material. Ethanol made from plant sugars is blended with gasoline to increase fuel efficiency. Algae, corn, wheat, rapeseed oil and sugar beets provide the basis for biofuels. This opens up a relatively new realm of renewable fuel to counteract carbon emissions.

Healthcare and Medicine

Doctors, nurses, and other medical staff must study biology to learn how to aid both humans and animals. Learning about the human body’s inner processes, organs, neurological system, blood, reproduction, development and diseases all prove essential for treatment and research.

Biological items also aid medicine. Many medicines contain plant-based ingredients. Aspirin was derived from the acetylsalicylic acid found in willow tree bark. Foxglove provides the basis for a heart medication. The anti-cancer drug Taxol is another example of a biologically derived medicine. Plants even form the basis for bandages, whether cotton or latex.

The realm of biotechnology also stands at the forefront of healthcare options. Additionally, many biological products are regulated for medical science and research use. Among these, blood and blood components, human tissue, monoclonal antibodies and proteins such as enzymes and growth factors all contribute to vital research for new medicines. Biology is far more than a school subject; it aids in making life better for everyone on Earth.

10. If one strand of DNA is
soldi70 [24.7K]

Answer:

Explanation:As previously stated, DNA is a macromolecule that's made up of individual subunits called nucleotides. Each nucleotide has three parts:

Brought to you by Sciencing

A deoxyribose sugar.

A phosphate group.

A nitrogenous base.

DNA nucleotides can contain one of four nitrogenous bases. These bases are adenine (A), thymine (T), guanine (G) and cytosine (C).

These nucleotides come together to form long chains known as DNA strands. Two complementary DNA strands bond to each other in what looks like a ladder before winding into the double helix form.

The two strands are held together through hydrogen bonds that form between the nitrogenous bases. Adenine (A) forms bonds with thymine (T) while cytosine (C) forms bonds with guanine (G); A only ever pairs with T, and C only ever pairs with G.

Complementary Definition (Biology)

In biology, specifically in terms of genetics and DNA, complementary means that the polynucleotide strand paired with the second polynucleotide strand has a nitrogenous base sequence that is the reverse complement, or the pair, of the other strand.
